Custom Design Printed Packaging Bags Aluminum Foil Zipper Matte Composite Bags Stand Up Bags

Description

Composite bags are packaging containers made of multiple layers of materials combined by bonding, heat sealing or other methods. They usually include different materials such as plastic, aluminum foil, paper, etc., and have moisture-proof, anti-oxidation, and UV protection functions. The following is a detailed introduction to composite bags:

Raw materials: The raw materials of composite bags include OPP, PE, POF, PPE, PP, composite films, etc.
Production process: The production process of composite bags is divided into side-sealed bags, bottom-sealed bags, middle-sealed bags, three-side-sealed bags, etc., requiring four different machines.​

Feature

1. Outer layer: enhance the mechanical strength of thebag body,
2. Heatresistance, printing performanceand optical properties, etc.
3 Middle layer: the main function of the compositestructure.Such as barrier,
shading,incense, etc.
4 Innerlayer: mainly used for sealing, followed by thepressure of the package material,
drop,sealing performance, etc.

Application:

Snack food packaging
Composite packaging bags can effectively prevent the oxidation and moisture of snacks such as potato chips and nuts. For example, potato chip composite packaging bags are generally composed of multiple layers of materials. The outer layer is a plastic film with good printing performance, which can display exquisite patterns and product information; the middle layer is aluminum foil, which has a strong barrier to oxygen and water vapor and can maintain the crisp taste of potato chips; the inner layer is food-grade polyethylene (PE), which can directly contact food and has good heat sealing properties, which is convenient for sealing and packaging.
