Aluminium-Composite Bags

Aluminium-composite bags come in a variety of composite structures, and depending on the application, it is essential to test which aluminum composite delivers the best results. During storage, the foil must not delaminate, nor should the packaged goods be damaged.

Typically, a PET film is laminated onto the aluminum from the outside, while the inside is lined with polyethylene, which allows for easy sealing. The PET outer layer also allows for high-quality printing.

Due to the metallization of the carrier layer, the resulting composite foil provides excellent protection not only against moisture and temperature fluctuations but also against oxygen and light/UV exposure. This makes it ideal for products in the chemical, medical, and pharmaceutical industries, as well as for aroma-sensitive goods like coffee and other foods.

Protection against:

• Moisture
• UV light
• Contamination
• Mechanical impacts
• etc.

The metallization of the backing layer gives the resulting composite foil excellent protection, not only against moisture and temperature fluctuations but also against oxygen and light/UV exposure.
This makes it ideal for products in the chemical, medical, and pharmaceutical industries, as well as for aroma-sensitive goods like coffee and other foods.

For many products and applications, aluminum composite bags are the optimal packaging solution. Their superior aroma barrier allows for the long-term storage of spices, tea, and roasted coffee.

When packaging roasted coffee, a sealed valve in the bag is essential. Roasted coffee releases gases, which are vented through the valve. This is why it smells like coffee in the supermarket's coffee section. Nothing from outside can enter the bag through the valve.

Aroma protection packaging is available as flat, stand-up, and side gusset bags made from aluminum laminated foil.

Bag types:

• 2-side seal
• 3-side seal
• 5-stitching
• Back-stitching
• Stand-up 

With optional tear notch, euro-perforation, lip, valve, or zipper closure.
