Aluminum foil pouches and composite pouches are widely used in food and electronics packaging. With the development of packaging technology, the quality, performance, aesthetics, and practicality of aluminum foil pouches and composite pouches have been qualitatively improved. So, what are the main differences between aluminum foil pouches and composite pouches ？

Aluminum foil pouches are divided into three-layer composite aluminum foil pouches and four-layer composite aluminum foil pouches, composite pouches which can be further divided into ordinary aluminum foil pouches and high-temperature sterilization aluminum foil pouches. The outer layer is made of PET, the middle layer of the composite pouch is made of pure aluminum foil, and the inner layer is usually made of PE or CPP. The center of the four-layer aluminum foil pouch is made of PA, which can greatly increase the strength and insulation function of the aluminum foil pouch. The shape of the aluminum foil pouch is clearly visible in the supermarket; it is still a three-sided package, with a bottom and side gussets. This shape is conducive to placing items and has a three-dimensional feel.

Aluminum foil pouches have heat-sealing, insulation, and light-shielding functions, excellent physical strength, and are very suitable for vacuum packaging of food, electronics, medicine, and exported precision equipment. Other composite packaging bags are mostly divided into two-layer or three-layer structures. The common outer layer is BOPP, and the inner layer is polyethylene. The isolation function of this common composite packaging bag cannot meet the high-temperature sterilization of food and can only achieve the normal packaging effect of goods. However, various beautiful pictures can be printed, and the price is relatively cheaper than aluminum foil pouches.
