In the packaging industry, Polypropylene (PP), due to its low cost and heat resistance, is often used for plastic bottles and films for food and medicine. Polyethylene has wide applications: Low-Density Polyethylene (LDPE) is made into food cling films and packaging bags, Linear Low-Density Polyethylene (LLDPE) is used for heavy-duty cargo stretch films, and High-Density Polyethylene (HDPE) is the top choice for large-capacity barrels and cans of chemical products. In the polystyrene family, General Purpose Polystyrene (GPPS) is used for small transparent gift boxes, and High Impact Polystyrene (HIPS) is used for buffer packaging of home appliances. Polycarbonate (PC), with its high transparency and strong impact resistance, is often used to replace high-end wine and beverage glass bottles. Acrylonitrile Butadiene Styrene copolymer (ABS) is used for packaging boxes of high-end electronic products to provide reliable protection.
