At present, there are many enterprises producing cosmetics, and there are many kinds of packaging materials used in cosmetics. The materials of cosmetic packaging also include PP, PE, PET, ABS, AS, acrylic, etc. Today, let's talk about what materials are suitable for cosmetic packaging.
PP is also called polypropylene, a semi-crystalline material, it is a kind of high density, no side chain, high crystalline linear polymer, has excellent comprehensive performance. Usually used for cosmetics container wall thicker cream bottles, bottle caps, bottle stoppers, etc.
Polyethylene, referred to as PE, is a thermoplastic resin made by the polymerization of ethylene. Good chemical stability, can resist the attack of most acids and bases (not resistant to acids with oxidizing properties). Insoluble in general solvents at room temperature, small water absorption, excellent electrical insulation.
PET material is an environmentally friendly material, with high barrier properties, light weight, non-crushing characteristics, chemical resistance, strong transparency, can be made into pearlescent, colored, magnetic white, transparent, widely used in the installation of gel water.
ABS is a thermoplastic polymer material structure with high strength, good toughness and easy processing and molding. Also known as ABS resin. Good overall performance, high impact strength, chemical stability, good electrical properties.
AS transparency is better than ABS, and toughness is better. For pots, cups, bottles, etc., transparency, high safety, resistance to fall.
Acrylic is made of injection molded bottles with poor chemical resistance. Generally, paste cannot be directly filled. It needs to be blocked by an inner container. The filling is not easy to be too full. It prevents the paste from entering between the inner container and the acrylic bottle to avoid cracking. The packaging requirements during transportation are relatively high. After scratching, it looks especially obvious, has high permeability, and the upper wall is especially thick, but the price is quite expensive.
