  1. It is well known that the appearance of acrylic packaging effectively solves the problem of insufficient appearance of plastic bottle packaging. This appearance is similar to the packaging of glass bottles and has the advantages of plastic bottle packaging. Therefore, it is popular with cosmetic container manufacturers and is currently the mainstream type of cosmetic packaging. One of the plastic bottles is the preheating safety of the plastic bottle package. Due to the high temperature and the release of harmful substances, the internal structure of the plastic bottle is unstable, which has been a concern of many consumers. However, we believe this can be based on the idea of applying a pesticide bottle to a bottle to solve the corrosion problem of the plastic bottle. It is obviously a good idea to develop coating materials in plastic bottles to achieve a stable structure similar to glass bottles without releasing harmful substances. The advantages and disadvantages of cosmetic glass packaging and plastic packaging have been around for a long time. You will find the absolute advantage of using plastic packaging instead of glass packaging. The same is true. The share of glass packaging in pharmaceutical packaging is declining year by year and is accelerating, and glass packaging is being replaced by plastic packaging. The replacement of cosmetic packaging materials that look simple is not straightforward. Why reject high quality, inferior cosmetic glass bottles? The root cause is that it is driven by the economic interests of the upstream and downstream of the industrial chain. The dispute between plastic packaging and glass packaging is the battle between the cosmetics company and the glass packaging company. Acrylic wear resistance is close to that of aluminum, with good stability and resistance to a variety of chemicals. Acrylic has good printability and sprayability, and cosmetic bottle manufacturers can achieve the desired surface finish of acrylic glass products through proper printing and spraying processes. The transparency of the acrylic plate is comparable to that of glass, but the density is only half that of glass. In addition, it is not as brittle as glass, and even if it is destroyed, it will not form sharp fragments like glass. The acrylic sheet has an abrasion resistance close to that of aluminum and is resistant to corrosion by various chemicals from time to time. Acrylic sheets have good printability and sprayability. Acrylic products (acrylic products) have the desired surface finish through proper printing (such as screen printing) and spray coating.

  2. Lotion bottles come in a variety of shapes, sizes and forms. They are made from many different types of materials, mostly plastic, glass or acrylic containers. Because of the variety of lotions, whether it is the face, hands or body, the formula of the lotion is very different. This is one of the reasons why lotion bottles are very diverse. Not only that, but there are many options available that allow consumers to choose what they like. Some specific products are contained in bottles that are not well made or difficult to use. The following includes some different options for storing emulsions. Some lotion is stored in a test tube with a lid. These tubes are usually made of plastic and can hold a lot of emulsion depending on their size. Plastic tubes with lids are not always the best choice, but involve lotion bottles. Whether it's a cream, hand cream or other lotion, the lotion sometimes builds up and clumps around the spout. If applied improperly, the lotion will collect on the nozzle or cap, which can be wasteful and can cause confusion. Another problem that some people might have with a capped test tube is that if they forget to completely close the cap, the lotion will be exposed. Over time, this will dry the emulsion and reduce its effectiveness. Secondly, some lotion bottles are also made of plastic, but they do not have a top of the pump cover, but a dispenser with a pump. This is useful for many people who don't want to unscrew or tighten the top or don't want to flip. Pump dispensers are available in a variety of options. There are smooth pumps, lock pumps, lock pumps and foamers. For those who have problems with the power in their hands, this method may be the least laborious. Therefore, for those who have difficulty grasping or twisting things, this option is preferred. The most obvious disadvantage of this method of retaining the emulsion is that it may be as easy as a few times depending on the amount of lotion required. Ningbo RuiChang Commodity Packaging Co , Ltd is a professional manufacturer and supplier of Lotion Pump in China. Would rather provide you with a quality lotion pump.

  3. Cosmetic Airless Bottles are considered a true breakthrough in cosmetic packaging innovation. The airless bottle prevents air exposure, which helps to protect and hide the cream, serum and foundation packaged in each container. Airless bottle packaging helps the shelf life of cosmetic packaging increase by more than 15%. The innovative technology used in these airless bottles includes a diaphragm to help evacuate the product and allow any waste to be used in the bottle. Advantages of use Compared to other cosmetic packaging containers, airless bottles include: The double-walled airless bottle gives the customer the feeling of using luxury goods. However, the double wall has a useful function as a double protector for internal products. Clear plastic wall airless bottles are the perfect choice to add branding logos to the outside. In addition, it allows product coloring to be viewed from the outside to the customer before purchase. airless bottles are also ideal for sensitive products such as natural skin creams, serums, foundations and more. In addition, due to the design and function of the gas-free bottle, it provides a lot of waste for customers and their special product materials. The dose is accurate for each pump. As the piston rises, the customer will drop each product. This prevents customers from causing air contact and difficulty extracting the remaining product. Ningbo RUICHANG Commodity Packaging CO , Ltd. . specializes in the production and supply of high quality Cosmetic Airless Bottles in China, from product development, mold design, material selection, production and processing to “quality”. Efficient production of industry-leading cost-effective cosmetic packaging. Products are exported to Europe and Southeast Asia, and are well received by customers.

  4. PP Bottle are mostly random copolymerized PP resins, which are required to have high fluidity, transparency, rigidity and certain impact resistance, and require high finish, heat resistance and chemical resistance. The melt flow rate (MFR) of PP suitable for the injection-blowing process is 2-20 g/10 min, but most of it is 6-14 g/10 min. Due to the hollow blow molding grade resin, the relative molecular mass distribution is generally wide. In addition, in order to meet the requirements of use and aesthetic requirements after packaging products, PP raw materials must have certain stiffness, impact resistance and high transparency. When producing a random copolymerized PP for a polymerization bottle, attention should be paid to the following control relationship. (1) Relationship between the amount of ethylene and transparency. As the ethylene content increases, the crystallinity of the random copolymerized PP decreases, and the transparency is improved to some extent. In the production of PP resin for bottles, according to the physical properties of processing technology and product transparency, the total ethylene mass fraction is generally controlled at 1.0% to 4.0%. The introduction of ethylene segments in the polymer chain structure can prevent the crystallization of PP. To avoid the formation of large spherulites and to improve transparency. (2) Relationship between ethylene content and rigidity and toughness. With the increase of ethylene content, the cantilever beam notched impact strength of random copolymerized PP is improved, and the yield tensile strength is gradually decreased. Compared with the homopolymer PP, the ethylene segment is introduced into the random copolymerized PP molecular chain, and the molecular regularity is lowered, which causes the crystallinity of the polymer to decrease, and the notched impact strength of the cantilever beam of the product is improved. The excellent impact resistance of the polymer means a loss of rigidity. As the MFR of PP decreases and the ethylene content increases, the cantilever beam notched impact strength increases, but the rigidity deteriorates. This is manifested by a decrease in yield tensile strength, Rockwell hardness and flexural modulus. Therefore, in the molecular design of the beverage bottle resin, it should be considered comprehensively. The beverage bottle forming process requires the resin to have a high melt strength. Therefore, a small amount of ethylene (mass fraction 1% to 4%) is added during the polymerization process, which not only increases the notched impact strength of the cantilever beam but also reduces the rigidity. (3) The effect of the amount of clearing agent added on the transparency of the product. In addition to selecting a suitable amount of ethylene, in order to achieve a satisfactory transparency effect, a nucleating agent which enhances the transparency can be added in the mixing process of the random copolymerized PP to make the transparency more desirable. In addition, due to the presence of crystal nuclei, heterogeneous nucleation is caused, the crystallization rate is accelerated, and the crystal size is uniform, which compensates for the rigidity loss caused by ethylene-propylene copolymerization to a certain extent, so that the resin has good physical properties and shortens molding. Time to reduce the wall thickness of the product. By adjusting the MFR and relative molecular mass distribution, and adding a suitable transparent nucleating agent, a special bottle resin for MFR with a relative molecular mass distribution of about 10g/10min is developed to meet the market demand. https://www.ruichangpacking.com
  5. The appearance of different levels of packaging for cosmetic bottles requires versatility, but it also has its inherent characteristics. The commonalities of appearance requirements include packaging printing patterns and writing should be neat, clear, not easy to fall off, and the color should be uniform. The particularity of the appearance requirements varies depending on the type of packaging. For bottle packaging, the bottle is required to be smooth, smooth, uniform thickness, no obvious scars and deformation, no cold bursts and cracks; the mouth should be straight, there should be no burrs (hairs), lines, bayonet, mating structure It should be intact; the bottle and cap should be tightly fitted and should not be slipped, loose or leaky; the inside and outside of the bottle should be kept clean. 1. Material requirements In order to achieve sustainable packaging, bio-based biodegradable materials have emerged and become a hot topic in the industry. Bio-based biodegradable materials are a new class of materials made from renewable materials, such as crops, trees, other plants and their residues and inclusions, by biological, chemical and physical methods. Products made from bio-based degradable materials are typically green, environmentally friendly, renewable raw materials and biodegradable at one level. At present, major companies such as DuPont and BASF are actively expanding their bio-based chemicals business. As a packaging developer for cosmetics manufacturing companies, the author hopes that biodegradable materials will be used in cosmetic packaging in the future to promote the sustainable development of cosmetic packaging. 2. Structural design requirements For cosmetics, the first layer of packaging is very important and directly related to the quality of the product. The first layer of cosmetic packaging is mostly plastic containers. The structural design of plastic containers is inseparable from the choice of materials and molding processes. Commonly used plastic materials can be divided into two types of soft and rigid materials from texture: typical soft materials represented by PE and PP, and typical hard materials represented by ABS, PMMA, etc. Common molding methods for plastic containers include injection molding, blow molding, injection blow molding, and the like. However, regardless of the molding method chosen, the design and capacity design of the plastic container is critical. 3. Seal design Product sealing is a mandatory quality standard for the cosmetics industry. Usually choose gasket seal and quality (gross weight), volume, date of manufacture and shelf life, or production lot number and limited life, and choose GB / T191-2008 label and packaging. The logo in the logo should be clearly marked, complete and in place. 4. Capacity design There are two general forms of capacity marking: one is a product in which the contents do not flow by weight (g, kg) under normal temperature conditions, and the other is a volume in which the contents can flow under normal conditions. The temperature condition (ml L) is one unit. For products in which the contents can flow, when the weight (g) is used, the weight of the desired contents must be converted into volume units, volume (ml) = weight (g) / product density. This is because the inner cavity space is most conveniently and accurately detected with standard distilled water after molding the packaging container. In designing the capacity of the packaging container, time and temperature, preparation and filling, as well as changes in the volume and shape of the package caused by its own viscosity and other factors should be considered, and therefore should be left in an appropriate space. Design the full capacity of the packaging container. 5. Regulations and standards Full understanding of the relevant regulations and standards for cosmetic packaging is the premise and basis for good cosmetic packaging design. For example, in the No. 75 of the “Measures for the Supervision and Administration of Quantitative Packaging Commodities Measurement” promulgated by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, the net content of products is clearly defined: the quantitatively packaged goods, due to changes in water content, changes in net content Very big. Producers should take measures to ensure that the net content of the goods is accurate under the specified conditions. Therefore, we must make up for these changes by considering the fact that powder products will become smaller over time and the fact that aquatic products will alleviate over time. This should be taken into account when designing the transparent packaging capacity. At the same time, cosmetics manufacturers should also keep abreast of the laws, regulations and standards of national, local and enterprise-related products, such as the “Regulations on the Administration of Cosmetic Labels” and the “Regulations on the Supervision and Administration of Cosmetics”. Hygiene, etc., to ensure that cosmetic packaging meets the relevant provisions of laws and standards. . Meet production requirements Online filling is actually to check whether the packaging design is perfect and the quality of the container is qualified. Because during the preparation and filling process, the substance or substance body is subjected to agitation and impact between the materials to generate bubbles and foam, resulting in a volume change. For example, gel products have a high viscosity and introduce a large amount of air during the mixing process, which causes a large amount of air bubbles to be stored in the semi-finished product, thereby affecting the volume of the product. Shampoo products have an inherent blowing agent component and will be present during the filling process. Due to the high velocity impact, a large amount of foam floats on the surface of the material, thereby increasing the space required for the container; the viscosity of the cream product is high, and the cream surface on the cream surface will have a tapered process after filling. Leveling, if the product combination is completed at this time, the cream body will be in contact with the sealing sheet, which will not only affect the appearance of the combined product, but also cause secondary pollution of the product. Therefore, these phenomena should be fully considered when designing the capacity of these products. In addition, in the scale production process, the packaging component parts need to be suitable for operation on a high-speed assembly line; the requirements for labels, printed patterns and lot numbers on the surface of the container can tolerate the friction generated during high-speed conveyance; Container structure. Stay steady and no dumping will occur. Otherwise, the normal operation of the packaging process, the labor intensity of the operators and the economic benefits of the enterprise will be directly affected.

  6. French square bottles provide stylish packaging for a variety of goods. Made from sturdy, thick-walled glass, these bottles are easy to clean and ready for packaging, as most types of glass can withstand the higher temperatures required for sterilization. Glass French square bottles can also be reused and recycled without sacrificing strength or quality. Paired with a vinyl-lined phenolic screw cap to eliminate any chemical interaction between the lid and the product and seal the integrity of the product. When considering square bottles for your product, the classic French square bottle offers a high and sturdy version with beautiful beveled edges and four flat panels for easy label and display product information. With their iconic look, they attract a large consumer market. Their square shape allows them to be tightly packed into boxes for transport, saving space and possibly reducing transportation or other transportation costs. Like other shaped bottles, they have a wide mouth that makes them easy to fill and allows for quick dispensing of contents. They can be paired with a continuous threaded screw top or other closure, such as a tamper resistant cap to improve product integrity. These square bottles range in capacity from 0.5 to 32 ounces. Which products are suitable for storage in French square bottles? Like all glass bottles, they are non-porous and impervious, making them ideal for storing food or beverages because external contaminants cannot reach the contents. Common foods stored in such bottles include thicker items such as jams, sauces or syrups. Transparent glass square bottles provide product visibility and are commonly used to package medicines, or health and beauty products. They allow you to quickly assess product levels and reduce overfilling due to lack of visibility.

  7. Cosmetic Bottles come in different sizes and shapes. The most common shapes in cosmetic bottles are cylindrical, oval and rectangular, but some are unique in shape. Most cosmetic bottles are made of plastic or glass and usually have a lid or lid made of metal or plastic. Some of the products packaged in cosmetic bottles include shampoos, conditioners, foundations, nail polishes and nail polish removers. Other products in cosmetic bottles are shower gel, facial cleanser and toner, talcum powder and liquid hand soap. The shape, size and materials used to make certain cosmetic containers are usually determined by the ingredients. For example, creams and creamy eye shadows and blushes are typically associated with small round glass jars having a wide mouth, while skin emulsions are typically in the form of tall containers with narrow openings at the top. Nail polish bottles are usually small and made of glass, while nail polish removers are housed in larger plastic bottles. Perfume is usually packed in small glass bottles, while body lotions, shower gels, shampoos and conditioners are packaged in large plastic bottles. Just as the style of the clothing changes, some designs of cosmetic bottles will change over time. For example, some plastic bottles designed to hold shower gels have hooks at one end so they can be hung from the shower curtain rod or shower head. This is a modern innovation, because the hooks were used in any type of cosmetic bottle until the late 20th century. Cosmetic Bottles require a lid or lid to prevent spillage or leakage of contents and to maintain any aroma. Some bottles have threaded openings so that the lid can be screwed on, while the other bottles are unthreaded and have a plastic cover that can be snapped. The mouth of the bottle must be able to provide a tight, strong fit that not only prevents leakage, but also allows any mechanism such as a pump or sprayer to function properly. https://www.ruichangpacking.com
  8. 1, plastic bottles use plastic bottles are usually PP, PE, K, AS, ABS, acrylic, PET and so on. 2, all cream bottles, caps, stoppers, mats, pump heads and dust covers for thicker cosmetic bottles are injection molded. The PET bottle is formed in two steps, the tube blank is injection molded, and the product is placed in a bottle. Others, such as latex bottles and wash bottles with thinner container walls, are blown bottles. 3, PET plastic bottle material is environmentally friendly material, with high barrier property, light weight, not easy to break, chemical corrosion resistance, high transparency, can be made into pearlite, colored, magnetic white, transparent. It is widely used in gel water. The bottle mouth is usually equipped with 16#, 18#, 22#, 24# caliber, which can be matched with the pump head. 4, acrylic material is a plastic bottle, chemical resistance is poor, individual can not be directly installed and paste, need to cooperate with the internal gallbladder barrier, filling is not easy to overfill, prevent sticking into the internal and acrylic bottles, to prevent cracking, the packaging requirements near transportation are higher, because After scratching, the appearance is relatively high, the air permeability is high, the feeling is high, the feeling is high, the feeling is high, the feeling is high, the wall feels thick, but the price is very expensive. 5, silk screen has popular ink and UV ink, UV ink is better, gloss and three-dimensional sense, should be printed first to confirm the color mining, will spread on the screen of different materials. 6. Plastic bottle cosmetic caps are equipped with inner pad, lid, inner plug and some small spoons or droppers, mainly considering the convenience of sealing and monopoly.

  9. Glass cosmetic containers have many different uses, which is why they vary in size and style. For information on the different options, please continue reading below. Liquid foundation Liquid bases are usually kept in glass containers because they contain liquids and help prevent air drying. The dimensions of clear or frosted bottles include: 1, 2, 4, 8, 16 and 32 ounces. They have a variety of tops that can be used with them, including pumps or orifice reducers. The top cover can be made of aluminum or plastic and will be screwed onto the inside top. There is also a glass roll on the container, which is available in a clear or matte finish. These typically hold 0.35 ounces of liquid and can be used with a rolling top cover to make application easier. Transparent glass thick-walled cans are also used in liquid foundations because the caps are twisted and the foundation can be easily removed by the user. These are usually purchased in .5 ounces or 1 ounce sizes, but are larger and smaller available. These are thick glass, but there are plastic containers that can be opened and closed. Eye shadow Clear glass cosmetic jars of sizes .25 and 2.3 ounces are commonly used for eye shadows. These houses are compact and loosely shaded and twisted to make it easy to open. They have thick walls to protect the interior from the shadows and have different color covers to choose from. There are also square glass jars with round shapes to accommodate the actual product. They have a more luxurious appearance and can hold on average about 1 ounce or more. Lipstick Glass rolling containers are commonly used for lip gloss because they have different colors and make application easy. Rolling balls can also save money because they do not require a separate applicator. They have clear and frosted glass and many other colors. They can hold 0.35 ounces and have a lid that can be screwed onto the rolled top. Transparent glass jars can also be used for lip gloss, but only for solids. The usual size is 0.25 ounces and the wall thickness is 2.3 ounces. They have a twisted lid so users can easily get the internal lip gloss. perfume Perfume is suitable for glass containers because the oil inside it does not seep out like plastic. Commonly used container types are: perfume bottles, roller bottles, cylinders with sprayers, glass bottles and vials with dropper. These all have a cylindrical shape and typically hold between 0.5 ounces and 1 ounce in each cylindrical shape. The only exception is the regular glass container, which can hold 5 ounces or more, usually with a nozzle at the top. The top of the selection will depend on the application method the buyer wants (ie dropper, sprayer, rolling). Most smaller sizes are popular because they are suitable for wallets and are easy to carry. There are other glass shapes that can be used for larger perfumes, which vary in shape. They can hold 3.5 ounces and usually have double walls to add more protection. When choosing a cosmetic container, you will be faced with the material you choose to use for the product. Depending on your product, you can choose from glass, plastic or metal. In the following, some advantages and disadvantages of choosing to use glass as a cosmetic container material are known. Eliminate the risk of hazardous chemicals If you do any research on cosmetic containers and their materials, you will definitely find some information about the dangers of chemicals in plastics. The chemical compound bisphenol A (BPA) has been a headline news for the past few years. This compound is present in the lining of many plastic articles. A study was conducted to determine if BPA is harmful and found to be a factor in various health problems. Although immediate measures have been taken to eliminate bisphenol A in food, health and beauty containers, it is still receiving the attention of many consumers. Choosing a glass cosmetic jar eliminates the risk of BPA mink entering the product. Glass containers contain no harmful chemicals and provide a safe container for your cosmetics. Help the environment Green environmental protection is a major trend in the beauty industry. The brand notices trends in consumers and wants to be more environmentally friendly. One step toward a more environmentally conscious company is to turn to glass cosmetic containers. The environmental benefit of choosing a glass is that the container can be reused or recycled after use. It is possible that plastic containers will be discarded after the product has been used up. Many plastic cosmetic containers cannot be recycled. However, many consumers choose to keep glass containers and reuse them. Those who wish to process empty containers can choose to recycle. Provide more products to consumers In addition to health and environmental issues, most consumers are also interested in getting the most out of it. A major disadvantage of plastic containers is that many of them do not allow the user to remove the last product from the container. It is very frustrating to know that a product still exists in the container and that it is not capable of taking it out. Glass containers are generally easier to use. Glass cosmetic jars typically have wider openings that allow the user to remove the product with a finger or makeup tool. Although glass cosmetic jars have many benefits, they also have some disadvantages. Glass is often slightly more expensive than plastic when making Cosmetic Bottles . This means that additional funds are needed to create the product, and as a result, the cost of the finished product needs to be increased. However, many consumers are willing to pay a slightly higher price for quality products. Another problem with glass is that the container may fall and rupture. This is not only dangerous, but it also causes consumers to lose some products. These are factors to consider when selecting materials for cosmetic containers. https://www.ruichangpacking.com
