  • The aluminum foil bag adopts a three/four-layer structure (PET/aluminum foil/nylon/PE), so it has good waterproof, moisture-proof, anti-static, anti-electromagnetic interference, electrostatic shielding and other characteristics. Mechanical strength and good heat-sealability make it very suitable for packaging electronic components that are sensitive to static electricity and require moisture resistance.


In addition, it can also used for vacuum packaging of precision mechanical equipment, chemical raw materials, food, medicine, optoelectronics, circuit boards, and electronic components, or can also print various exquisite patterns, LOGOs, and colors according to customer requirements.
