PET/AL/PA/PE Multi-Layer High-Barrier Packaging Bag Film

Product information description:

Material:PET/AL/PA/PE

The PET/AL/PA/PE Multi-Layer High-Barrier Packaging Bag is a high-performance packaging solution that combines the advantages of four materials: polyester (PET), aluminum foil (AL), nylon (PA), and polyethylene (PE). Designed specifically for industries with stringent requirements for freshness and protection, such as food and pharmaceuticals, it ensures exceptional performance across a wide range of environments through its unique multi-layer composition.
The PET layer serves as the outer substrate, offering excellent mechanical strength and printability. It supports high-definition color printing and can withstand short-term high temperatures, ensuring the structural stability of the bag. The AL layer is the core barrier layer, providing comprehensive protection against oxygen, water, light, and odors, significantly extending the shelf life of the product. The PA layer, positioned in the middle as a reinforcement layer, boasts excellent toughness, puncture and tear resistance, and good oil resistance, making it ideal for long-distance transportation and large-format packaging. The PE layer, the inner heat-sealing layer, is non-toxic, tasteless, and has a high heat-seal strength, making it suitable for direct contact with food and pharmaceuticals while accommodating high-speed packaging operations.
The core advantages of this packaging bag lie in its extremely high-barrier properties, superior puncture resistance, and broad temperature tolerance range (-40℃ to 121℃), ensuring product integrity and freshness under various extreme conditions. Whether for frozen meats, seafood, high-temperature cooked foods, pharmaceutical raw materials, or pet food that require long-term storage or long-distance transportation, the PET/AL/PA/PE Multi-Layer High-Barrier Packaging Bag is the ideal choice.
