Fertilizer Packing Composite Bags Factory Composite Material Pouches
Composite packaging bags are packaging materials with multiple functions, made by combining two or more materials through composite processes. The following is a relevant introduction:
Structure and Materials
- Outer layer: Materials such as polyester (PET) and nylon (PA) are often used, providing good printability, wear resistance and mechanical strength.
- Middle layer: Mostly aluminum foil (AL), polyethylene (PE), polypropylene (PP), EVOH (ethylene-vinyl alcohol co polymer), etc., which play the role of barrier (moisture-proof, oxygen-proof, etc.), aroma preservation and strength enhancement.
- Inner layer: Generally made of polyethylene (PE), polypropylene (PP), etc., which have good heat-sealing performance to ensure the sealing of the bag mouth.
- Small packaging bags: They hold a small weight, usually made of single-layer or double-layer materials. For some with special requirements, they can also be made of multiple layers of different composite materials. They have a wide range of packaging applications, including liquids, powders, blocks and special-shaped objects.
Application Fields
Widely used in packaging fields such as food, medicine, cosmetics and industrial products, such as packaging snacks, beverages, medicines, cosmetics, electronic products, chemical products, etc.
