Applications & Uses

Suitable Substrates

This adhesive system is suitable for laminating printed and unprinted, transparent or metallized structures. It can be used for the lamination of aluminum foil, PET, cellophane film, BOPA, PE, PP cast and BOPP.

Typical Applications

The laminated structures with this adhesive system show high product and thermal resistance. It is recommended to the lamination of packaging for cookies, pet food, snacks, coffee, pasta, dry foods, labels, pharmaceutical and others.

Usage Recommendations

The increase in the lamination speed must be followed by an increase in the nip roller temperature. It is recommended that the temperature of the nip roller keeps between 10 and 15°C higher than the temperature of the metering roller.
