Aluminum-plastic composite heavy-duty bags are also called pure aluminum middle-sealed hemming bags, aluminum foil accordion heavy-duty bags, aluminum foil hemming heavy-duty bags, aluminum-plastic composite hemming bags, aluminum-plastic composite hemming bags, aluminum-plastic composite heavy-duty bags, Aluminum foil composite back-seal bags, aluminum-plastic composite middle-seal bags, particle heavy bags, M-shaped hemmed color masterbatch heavy bags, etc.
Aluminum-plastic composite heavy-duty bags are composite packaging in which aluminum film and plastic film are combined through one or more dry compounding processes to form a certain function.
Aluminum-plastic composite heavy bags are generally made of three layers of material films:
The first layer is the surface layer, which can ensure the strength, puncture resistance and anti-slip properties of the packaging bag within a certain temperature range;
The second layer is the barrier layer, which is usually made of aluminum foil to prevent moisture, light, and oxygen;
The third layer is the heat sealing layer, which has good adaptability, permeability resistance and heat sealing properties.
