The combined properties of Hydropol™ can be used with just one other plastic to produce a dual-layer barrier film with at least equivalent functional properties of a multi-layer film.
Additionally, printing without pre-treatment and removal of tie layers adds another simplified dimension. A simple hot water wash system can then remove the Aquapak layer enabling the other material to be cleanly separated and recycled. This brings the possibility of a whole range of complex layered pouches recyclable, with the solubilised Hydropol™ being biodegraded in the waste water stream or in Anaerobic digestion. Aquapak has a patented process to recover the PVOH back into virgin polymer for when sufficient volumes of
