There are many types of plastic packaging films, including polyethylene film, biaxially oriented polyester (BOPET), BOPP film, CPP film, etc. Each type of plastic film has its own specific characteristics and uses. For example, high-density polyethylene (HDPE) film has good high and low temperature resistance and impact resistance, and is suitable for various environments; while low-density polyethylene (LDPE) film is often used in plastic packaging bags due to its softness and good chemical stability. In addition, polyvinyl alcohol (PVA) high-barrier composite film is widely used in the food industry due to its extremely high barrier properties and environmental protection requirements. The types and characteristics of plastic packaging films enable them to meet the needs of different industries and provide effective solutions for product protection and transportation.
