PP (Polypropylene) is a thermoplastic engineering plastic polymerized from propylene monomers. It has excellent heat resistance, chemical corrosion resistance and good mechanical properties, and is one of the most widely used materials in the plastic packaging industry.
In the field of cosmetic packaging, PP is widely used in lotion bottles, cream jars, powder compacts, bottle caps, pump head assemblies and various injection-molded structural parts due to its stable, safe and environmentally friendly characteristics.
PP material has high temperature resistance, can meet the needs of hot filling and high-temperature sterilization, and at the same time has good resistance to chemical substances such as acids, alkalis and oils, making it suitable for containing skin care products, personal care products and functional formula products.
Through the Injection Molding (IM) process, PP can achieve complex structures, high-precision size control and diversified surface treatments, such as spraying, electroplating, screen printing, hot stamping, etc., thus meeting the dual needs of high-end brand packaging for appearance and function.
In addition, PP is also one of the important materials for the application of PCR (Post-Consumer Recycled) plastic. It can reduce environmental impact through recycling and reuse, which conforms to the current global development trend of sustainable packaging.
