Cosmetic packaging material is a kind of packaging material industry, which is divided into overall packaging material and partial packaging material.
The overall packaging material usually cosmetics manufacturers will provide drawings or general requirements, handed over to the packaging material manufacturer to produce, while some packaging materials are much more subtle, more specific and demand, divided into partial printing, bottle packaging, bottle body packaging. According to the different types of cosmetic packaging, some small accessories can also be specifically outsourced. The cosmetics packaging industry and cosmetics are closely linked, and now the overall homogeneity of the cosmetics industry has enhanced the value of packaging materials, and in recent years, industry insiders have also called for low-carbon, green packaging services.
1---PET?
Its main characteristics are high air tightness, good compressive strength, high water resistance, very transparent, its transparency is as high as 95%, higher than the transparency of other commonly used plastic packaging containers, but it is not heat-resistant, it is often used in food, beverage bottles, cosmetic bottle packaging materials. It is precisely because of its high air tightness and no capillary pores in the packaging container, so it is used to make a container for packaging alcohol.
2---HDPE
Chinese name high-density polyethylene, which is commonly known as high-density PE, is the second material on the international material identification number. Its main characteristic is good acid and alkali resistance. The products processed with it are translucent and not very good heat resistant, and it is used to make packaging containers with capillary pores. It is commonly used in chemical products such as pharmaceutical bottles, cosmetic bottles and packaging containers.
3---PVC
Chinese name polyvinyl chloride, which is the third material on the international material identification number,
Its main characteristics are transparent, not heat-resistant, before the advent of early PET, it is to replace PET, used in mineral water, juice and other beverages, the current main role is to manufacture building materials for water pipes, and wire enameled outer wire and other uses. Containers made from it will have pores, so it is not suitable for using it to hold wine.
4---LDPE
Chinese name low-density polyethylene, also known as low-density PE, it is the fourth material on the international material identification number, because of its low molecular density, so softer than HDPE, the product processed with it is translucent, not heat-resistant, with pores, but it has good acid and alkali resistance. Containers processed from this material are commonly used in chemical products such as facial cleanser, salad, glue bottle, cosmetic bottle hose, etc.
5---PP
Chinese name polypropylene, it is the number five material on the international material identification number, it is a high-density material, the product processed by it is translucent, heat-resistant, impact-resistant, acid-alkali-resistant, but has pores. It is commonly used in hot filling packaged food, microwaveable cooking tableware, high-temperature food and general household face plates, gargle cups and other daily necessities microwave-level processing such as: measuring cups.
6---PS
Chinese name polystyrene, it is the sixth material on the international marking material number, which is used to process the product transparency, good sealing, but fragile, not heat resistant. It is commonly used to seal cans,
Processing of food boxes.
7---PC
It is the No. 7 material on the international marking material number, and the products processed by it are transparent, highly heat-resistant and not easy to break. It is commonly used in the processing of feeding bottles, distillation barrels, heat-resistant barrels, and medicine bottles.
