Pallet Cover

Pallet Cover, commonly known as a pallet cover or pallet hood in English, is a large packaging protective product specifically designed to cover standard logistics pallets. Its core function is to protect the goods on the pallet from external environmental influences during storage and transportation.

Structure and Materials

Aluminum foil bags are usually composed of multiple layers of materials, each with its specific function. Common structures include:

Three layer structure (most common): PET/AL/PE

Outer layer (PET/nylon): Provides mechanical strength, abrasion resistance, tear resistance, and is suitable for printing.

Intermediate layer (AL aluminum foil): The core barrier layer provides light blocking, oxygen blocking, and moisture blocking functions. Usually, a thickness of 7-9 micrometers (μ m) can play a critical barrier role.

Inner layer (PE/CPP): heat sealing layer, ensuring that the bag can be tightly sealed and safely in contact with the contents. CPP is more suitable for high-temperature cooking.

Four layer structure (higher requirement): PET/AL/nylon/PE

Adding a layer of nylon further enhances the puncture resistance and durability of the bag, commonly used for packaging food or heavy parts with bones, edges, and other materials that may puncture the packaging.
