Polyester / aluminized polyester / polyethylene composite film is widely used in medicine and food packaging. The middle layer of the composite film is aluminized polyester, that is to say, a layer of aluminum is plated on the surface of polyester film by vacuum aluminizing method, which can effectively play the role of avoiding light and blocking. 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 polyethylene material makes the heat sealing process easier, and the pouch has excellent heat sealing strength, further extending the shelf life of the package.
