Polyester/Vacuum Aluminized Cast Polypropylene/Polyethylene Composite Film PET - VMPET - PE
Polyester/aluminized polyester/polyethylene composite film is widely used in medicine and food packaging. The middle layer of this composite film is aluminized polyester, that is, a layer of aluminum is plated on the surface of the polyester film by vacuum aluminizing, which can effectively play the role of light protection and barrier. The surface layer is also a polyester film with good barrier performance, which not only further improves the sealing performance, but also enables the film surface to carry printing ink well, and the printing effect is rich in color and clear in pattern. The inner layer of polyethylene material makes the heat sealing process easier during bag making, and the pouch made has excellent heat sealing strength, further extending the shelf life of the packaged goods.
