Ordinary cosmetics and washing products packaging containers are mostly made of high density and high density polyethylene HDPE. In order to meet the packaging requirements of different products, the materials used in plastic bottles have also become increasingly rich. Cosmetic plastic containers commonly used plastic materials can be divided into two major categories from the texture: soft materials and hard materials.
Typical soft materials for cosmetic containers include PE polyethylene, PP polypropylene, and the like. Appearance after processing: PE polyethylene white waxy translucent material, soft and tough, slightly stretchable, lighter than water, non-toxic. Can match colors, but the color is less vivid. PP polypropylene transparent or translucent material, excellent resistance to twisting. After color matching, the material has a brighter color.
Typical hard materials are ABS acrylonitrile-butadiene-styrene copolymer, PMMA polymethyl methacrylate, and the like. Appearance after processing: ABS material is opaque material with light ivory color. It can be matched into other bright products with high gloss. With tough, rigid and hard material characteristics. The PMMA material is transparent and has a light transmittance similar to that of glass. It has good transparency among plastics but has a low surface hardness. Easy to be scratched and scratched by hard objects.
