News » Introduction to LDPE Composite Aluminum Foil

LDPE Composite Aluminum Foil is a laminated material made by combining aluminum foil with low-density polyethylene (LDPE). This structure brings together the strong barrier properties of aluminum and the flexibility and sealing performance of LDPE. As a result, LDPE composite aluminum foil is widely used in industries that require high-quality and reliable packaging.

The aluminum layer blocks light, moisture, oxygen, and odors, ensuring long-term product protection. Meanwhile, the LDPE layer adds softness, heat-sealability, and tear resistance. Because of these features, LDPE composite aluminum foil is commonly used for food packaging, medical supplies, and industrial products. Its excellent strength and stability make it ideal for pouches, sachets, lids, and multilayer packaging solutions.
