PAP 22 Flow-Pack with Crystal Window for Dry Goods

Challenge

Manufacturers in the dry food segment face a clear dilemma: EU regulations and rising EPR tariffs are pushing them away from plastic composite films, but switching materials carries real operational risk.

  • The Fear: Any change in material stiffness, friction, or sealing behaviour can cause jams, sealing failures, or speed loss on high-speed HFFS/VFFS line
  • The Requirement: A new solution that runs as a ghost — mechanically identical to existing plastic films, while delivering genuine recyclability and a crystal-clear product window.

Solution

We engineered RAPID FLOW — a natural kraft paper flow-pack with an integrated crystal-clear window, classified as PAP 22 monomaterial (<5% non-fiber content).

Transition benefits:

  • Invisible Barrier: We utilized our advanced barrier paper technology. It provides an effective shield against moisture and aroma loss, ensuring the consumer experiences the full bouquet of the product upon opening.
  • Crystal Visibility: The window is crafted entirely from natural cellulose fibres. No PE film, no fossil-based materials — just paper.
  • Sustainability Upgrade: From composite plastic waste to standard paper recycling stream. One bin. No consumer sorting required.
  • EPR Savings: PAP 22 classification significantly reduces Extended Producer Responsibility tax exposure across EU markets.
