Polypropylene (PP): Common Uses in Daily Life
Polypropylene (PP), one of the top five plastics, sees widespread use in everyday items like foam boxes and plastic cups. Here’s how it’s categorized based on primary applications:
Injection Molding
People’s improved living standards boost the demand for PP injection molded products. Products like basins and buckets see peak sales during school seasons, while ornaments and gifts spike during holidays. PP injection molding is common in small appliances, toys, washing machines, and auto parts.
Wire Drawing
Environmental policies impact the demand for cement and building materials packaging, pressuring the plastic weaving sector. PP wire drawing adapts, focusing on either large-capacity or small, specialized packaging. Products include daily-use bags, woven sacks, food packaging, and clear bags.
Film Production
People divide PP films into BOPP, CPP, and IPP types, primarily for food packaging. Compared to PE bags, PP film bags offer better clarity and a sturdier feel. Demand peaks around holidays and festivals.
Fiber Applications
Manufacturers make polypropylene fibers via melt spinning for use in decor and clothing industries. These fibers are versatile, durable, and cost-effective.
Pipe Manufacturing
Non-toxic and heat-resistant PP makes it ideal for water supply and heating systems. PP pipes are lighter, more eco-friendly, and recyclable than alternatives. Their popularity peaks from March to May and September to October, aligning with construction seasons.
