Pressure on the supply chain to replace hard-to-recycle barrier laminates with mono-material alternatives is relentless, and bpi protec was showing its latest X-Enviro film range to help meet this demand.
The Berry Global (formerly RPC) company’s X-EnviroPouch material can be used in pre-made pouches or in form-fill-seal.
“There is none of the polyester that was typically included in this type of laminate,” says business development director Julie Eller. “But it has all the necessary stiffness and machinability.”
Different grades of polyethylene (PE) maintain the temperature differential between the sealing and top layers. “This means it can run more easily on existing packaging machinery, including those with zipper systems,” she says. “Customers are currently running shelf-life tests.”
Other film variants suitable for food are X-EnviroFresh and X-EnviroFrozen.
