Global flexible packaging and lidding films supplier KM Packaging offers mono-material food packaging with mono polymer structure lidding films.
KM Packaging offer mono polymer lidding films for all food tray types including PP, Alufoil, CPET, and APET.
Particularly relevant to the meat, poultry, fish and seafood markets, the company offers weld seal mono-material lidding films within our K SEAL range. These have an all-polyester structure and are available with a high-oxygen barrier. The company said they offer exceptional transparency, with excellent anti-fogging properties, and weld seals to rPET or APET trays.
KM Packaging said the entire single polymer pack is designed for recycling in the PET recycling system.
Charles Smithson, managing director of KM Packaging, said the sustainability of packaging solutions to protect, present, and preserve foodstuffs is a key consideration.
“Many manufacturers within the meat and fish industry face the problem of 'How can we move to more mono-material solutions to avoid putting multi-layer trays and films with different plastics combined into the market?’,” he said.
“Our product enables them to switch from hard-to-recycle mixed polymer plastics – for example a PET/PE food tray – to a mono-polymer food tray with the same mono-polymer top film to seal to it.
“Offering excellent weld seals to PET trays, K SEAL has exceptional clarity, anti-mist, and an effective barrier, performing in the same way as existing films used by meat and fish packers, while providing a packaging solution that is 100% designed for recycling in the number 1 PET recycling stream.”
KM Packaging said many tray manufacturers are also responding to the demand to move away from multi-layer and laminated materials for food packaging due to the difficulties of separating them for recycling.
Smithson said his company’s in-house technical team works closely with customers, tray suppliers, and sealing machinery manufacturers to assess and trial lidding films and find the right packaging solution for the application.
“We are currently seeing unprecedented interest from meat and fish packers across Europe for mono-material solutions,” he said.
“We continue to drive innovation in sustainable solutions and these additions to our K SEAL product range complement our existing mono-material lidding films found in our other core ranges, K PEEL and K FOIL. We are also working on incorporating Post-Consumer Recycled (PCR) content into these films.”
