Introduction

Plastic plays an important role in cosmetic packaging materials, and the core components of the pump head, spray, bottle cap and other materials supporting the container are plastic, so there is a close relationship between cosmetics and plastic. Among them, the main plastic materials are PP, PE, ABS, PET, PCR, PMMA, etc. In order to distinguish them, it is necessary to understand their characteristics and differences.

PP、PE:

PP and PE are environmentally friendly materials, which can be directly in contact with cosmetics and food, and the material is white and translucent.

1.PP (polypropylene) density is small, the raw material appearance is transparent and light, with chemical resistance, collision resistance. Common cream bottles and hand drawn gaskets are PP materials.

2.PE can be divided into HDPE (high density polyethylene) and LDPE (low density polyethylene). It has perfect chemical resistance, in the field of cosmetic packaging material application, PE material is mainly used in PE hose, PE bottle cap. PP's comprehensive performance is better than PE, PP products light weight, good chemical resistance.

ABS:

ABS is an engineering plastic,not environmentally friendly,high hardness is not easy to deformation, heat resistance, low temperature resistance is good, but can not directly contact with cosmetics, food, in the acrylic cosmetic packaging material is generally the inner cover, shoulder cover material. The color is yellowish or cream white.

PET:

PET (polyester),also known as polyester resin, is made of milky white or light yellow raw material with good transparency and non-toxic properties.It has the characteristics of high density,high hardness, abrasion resistance, but not heat resistance to water soaking or alkali, etc. Part of the polyester material family like PET, including PBT and PETG, is pure as crystal. The hygiene and safety is very good, which also makes them widely used in cosmetic container packaging.

PCR:

The PCR is a kind of Recycled material,the full name is Post-Consumer recycled material,that is,after consumption recycling. PCR is a recycled materials formed by the reprocessing of some waste raw materials,mostly from mineral water bottles,shampoo bottles,lunch boxes,milk bottles and other waste plastics.
