AquaFlex paper: PVOH coating and lamination for heat-sealable paper packaging
Paper that seals, with or without a high barrier
Both keep paper as the main material. The AquaFlex layer replaces the plastic film that usually makes paper sealable.
Heat-sealable paper
For non-food packs: toys, cosmetics, accessories and electronics. The AquaFlex layer gives the seal and a printable surface.
High-barrier paper
For food that needs protection from oxygen and moisture: butter, snacks, chocolate and candies.

What was tested
AquaFlex L-BAR and L-OPV coatings on cardboard passed EU food-contact tests (Eurofins MTS Vietnam, 2024).
AquaFlex coating dissolves during paper repulping.
The ISO 14852, ASTM D6691 and ISO 14855-1 results apply to AquaFlex film and coating only, not to the paper laminate as a whole.
AquaFlex paper is also presented on turngreen.world, the TURN GREEN group site.
AquaFlex paper questions
What is AquaFlex paper?
It is paper laminated or coated with AquaFlex, our PVOH material, in place of a plastic layer. The AquaFlex layer makes the paper heat-sealable, and with a metallized layer it gives a high barrier.
Can AquaFlex paper run on my form-fill-seal line?
It is made for vertical and horizontal FFS machines. Send us your product and your packing line and we run a paper trial first.
What happens to the AquaFlex layer when the paper is recycled?
AquaFlex coating dissolves during paper repulping. Our lab test results apply to the AquaFlex film or coating only, not to the whole laminate.
Is AquaFlex paper suitable for food?
The 3 layer metallized structure is designed for butter, snacks, chocolate and candies. AquaFlex L-BAR and L-OPV coatings on cardboard passed EU food-contact tests (Eurofins, 2024). Ask us for the report that matches your structure.
