What are the types of packaging film

The packaging film is mainly mixed and extruded from several different grades of polyethylene resin, which has puncture resistance and high strength. It wraps and wraps the goods stacked on the pallet to make the packaging more stable and tidy, waterproof, and is widely used . The type of packaging film differs depending on the material. Its types are: 　　 PVA coated high barrier film: Its main raw material is polyethylene, where PVA is added with nano-inorganic substances and coated on the surface of the polyethylene material to form this High barrier film.　　 Biaxially oriented polypropylene film: It is made of polypropylene by biaxially oriented. This kind of film has poor printing effect and poor ink adhesion. Therefore, it is often used as a packaging material that is not printed.　　 Low-density polyethylene film: Low-density polyethylene film has average printability. Because of its high cost and high price, it is rarely used.　　Polyester film: Polyester film is often used as a substrate in composite materials. Each packaging film has its own characteristics and can be selected and used according to the characteristics of the product packaging.　　 Cast polypropylene film: It is a polypropylene film produced by a casting process with good sealing properties. The thickness of the cooking class film is generally 60 meters ℃ μ ~ 80, 121, 30 minutes capacity, high temperature cooking, oil resistance, good air tightness, and high heat seal strength.　　 The above is to explain the types and uses of packaging film for everyone.
