Cosmetic Bottles Packaging Requirements

Recommended Posts

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.
