Cosmetic packaging materials, especially skincare packaging materials, are mainly divided into two categories: glass and plastic. What are the uses of cosmetic packaging materials? If you want to know, come and take a look.
The type of cosmetic packaging material is plastic, including PP, PE, PS, PET, PETG, AS, ABS, acrylic, etc. In fact, the common PP material is polymer polypropylene, while plastic is a polymer compound. Harmless, odorless, heat-resistant, cold resistant, and chemically stable. The chemical properties are not easily altered. Another characteristic of this type is milky white, translucent, smooth, and non greasy; PP bottles are softer than PET, easier to pinch, and have lower transparency, so opaque shampoo bottles are commonly used (easy to squeeze). In fact, when coloring, the main use is to use color masterbatches produced by specialized manufacturers (high color concentration particles composed of colorants, carrier resins, and dispersants). Cosmetic packaging materials have good coloring effects. In the production process of cosmetic packaging materials, the color masterbatch is directly added to the product, and after stirring, it can enter the next process normally, and the finished product will have color.
The cosmetic packaging material PE is basically opaque, and the material will be relatively soft, not as smooth as PET. Suitable for hose, lotion bottle, bottle cap, etc. In fact, this product is mainly thermoplastic polyester, with a smooth and glossy surface that can resist friction, good dimensional stability, and high hardness. However, it is not resistant to hot water, immersion, and alkali. This material is environmentally friendly, with high barrier properties, lightweight, not easily damaged, resistant to chemical corrosion, and strong transparency. It can be made into pearlescent, colored, magnetic white, and transparent. Cosmetic packaging materials are widely used in gel water. The transparency of PETG used in the market is better than that of PET, but it is not common in China due to its high cost, high waste, one-time molding, and non recyclable materials. PETG is used for various daily necessities, such as cosmetics bottles, perfume bottles, drug packaging containers, etc. Compared to PET, PETG has higher transparency. And it has better chemical resistance, oil resistance, and weather resistance (yellowing) than PET. In short, current cosmetic packaging materials are all engineering plastics, which are not environmentally friendly and have high hardness. They cannot come into direct contact with cosmetics and food. In acrylic cosmetics packaging materials, it is generally used for inner and shoulder covers. The color is light yellow or milky white. Of course, it should be noted that if the cosmetic packaging material will come into direct contact with the material, please note that there must be no alkane lubricating oil in the material, as it can cause water absorption, expansion, deterioration, brittleness, and cracking in the amorphous region.
After the introduction of the above content, I believe everyone also knows the purpose of cosmetic packaging materials. After reading the article, if you encounter such a situation, you will know where to choose from. I hope it can bring you help. Of course, Yuheng Plastics' products can still meet these needs, and we also welcome the establishment of long-term cooperative relationships with friends from all over the country.
