Types of plastic film: PVA coated high-barrier film: PVA with nano-inorganic substance is coated on polyethylene film and then printed and compounded. It can be used for packaging beverages, milk, soy sauce, vinegar, etc. Biaxially oriented polypropylene film: It is made by co-extruding polypropylene particles to form a sheet, and then stretching it in both vertical and horizontal directions. It is currently the most widely used printing film. Low-density polyethylene film: Generally, it is made by two processes: blow molding and casting. The thickness of cast polyethylene film is uniform, but due to the high price and low cost, it is the most widely used. Polyester film: Using polyethylene terephthalate as the raw material, it is made into a thick sheet by extrusion, and then made by biaxial stretching. It is one of the commonly used barrier composite film substrates. Nylon film: a very tough film with good transparency, good gloss, high tensile strength, high tensile strength, and good heat resistance, cold resistance, oil resistance and organic solvent resistance, Excellent abrasion resistance and puncture resistance. Cast polypropylene film: The polypropylene film produced by the casting process can be divided into ordinary CPP and cooking grade CPP. It has excellent transparency, uniform thickness, and uniform vertical and horizontal performance. It is generally used as the inner part of composite film.层材料。 Layer material. Aluminized film: mainly includes polyester aluminized film and CPP aluminized film. Aluminized film has both the characteristics of plastic film and the characteristics of metal. The use of plastic film PVA coating high-barrier plastic film: can be used to package beverages, fruit juices, milk, soy sauce and vinegar, etc. Biaxially oriented polypropylene film: widely used in the printing field. Low-density polyethylene film: It is often used as an inner film for composite flexible packaging materials. Polyester film: one of the commonly used barrier composite film substrates. Nylon film: suitable for packaging hard items, such as greasy food, meat products, fried food, vacuum packaged food, etc. Cast polypropylene film: This material is used in general gift packaging bags. Aluminized film: It is widely used in composite packaging.
