Polyethylene (PE)：
- Low-Density Polyethylene (LDPE)：LDPE is flexible and tough, with good transparency. It is widely used in supermarket shopping bags, outer packaging bags, and heat shrink films. It is also an ideal material for food packaging due to its non-toxic and odorless properties, such as being used to package biscuits, candies, and other food items235.
- High-Density Polyethylene (HDPE)：HDPE is more durable and has higher strength compared to LDPE. It is commonly seen in shopping bags, vest bags, and inner packaging bags in shopping malls. Additionally, it is used to make containers, pipes, and other products due to its excellent chemical resistance and mechanical properties12.
- Linear Low-Density Polyethylene (LLDPE)：LLDPE combines the advantages of LDPE and HDPE, with good tensile strength and puncture resistance. It is often used in the production of cling films or blended with LDPE for better performance2.
Polypropylene (PP)：PP has good toughness, is not easily broken, and has excellent tensile and wear resistance. It is mainly used for loading and transporting heavy items like building materials, chemical products, and agricultural and sideline products. Moreover, it has certain moisture resistance and can effectively protect items, along with good acid and alkali resistance. PP is also widely used in the packaging of textiles, clothing, and electronic products35.
Polyvinyl Chloride (PVC)：PVC has high transparency, good softness, and excellent weather resistance and corrosion resistance. It is widely used in the packaging of light industrial products such as cosmetics, stationery, toys, and knitted fabrics, as well as in the packaging of heavy industrial products like furniture, electrical appliances, and hardware products23.
Polyvinyl Alcohol (PVA)：PVA has high transparency, good softness, is not prone to static electricity, and has excellent moisture-proof and preservation effects. Therefore, it is often used in the packaging of food, medicine, cosmetics, and other products to ensure the safety and hygiene of the products during storage and transportation3.
Ethylene-Vinyl Acetate Copolymer (EVA)：EVA has good flexibility, environmental stress cracking resistance, and weather resistance. It is widely used in functional greenhouse films, foamed shoe materials, packaging molds, hot melt adhesives, wire and cable, and toy fields
