Cosmetic Case

PP is a colorless, odorless, nontoxic and translucent solid substance. Polypropylene (PP) is a kind of thermoplastic synthetic resin with excellent properties. It is a colorless and translucent thermoplastic light general plastic. It has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing performance, etc., which makes polypropylene rapidly developed and applied in many fields such as machinery, automobile, electronic appliances, architecture, textile, packaging, agriculture, forestry, fishery, food industry, etc. Because of its plasticity, polypropylene is gradually replacing wood products, and high strength, toughness and wear resistance have gradually replaced the mechanical function of metal. In addition, polypropylene has good grafting and composite functions, and has great application space in concrete, textile, packaging, agriculture, forestry and fishery.

PP chemical modification, through copolymerization modification, cross-linking modification, grafting modification, adding nucleating agent and so on, can change the macromolecular structure or crystal structure of PP and improve its mechanical properties, heat resistance, aging resistance and other properties. PP chemical modification, through copolymerization modification, cross-linking modification, grafting modification, adding nucleating agent and so on, can make PP macromolecular components and The mechanical properties, heat resistance and aging resistance are improved by the change of macromolecular structure or crystal structure.

This cosmetic case has a modern appearance and can be used for many different purposes. It is especially suitable for many special market demands and can provide different color combinations. Different forms of inner cavity such as blister forming, forming sponge, egg shaped sponge can be applied.
