®Sarafil Polyplex Polyester Films

Type: HSE101-R7 Co extruded PET film 15my

Sarafil HSE101-R7 is co-extruded Polyester film with one side heat sealable surface and other side corona treated. The film is produced with 70% post consumer recycled content. It is an Eco-friendly film, contributes to significant carbon footprint reduction in packaging and other applications. It exhibits excellent heat seal, thermal and mechanical properties. Heat seal surface is designed to seal to itself, themoformed APET, CPET, unsaturated polyesters, paper. HS does not seal against polyolefins (PE, PP) and PS. Heatseals are non peelable.

It is the responsibility of the manufacturer of the final packaging and of the food packer to ensure the suitability of ultimate pack for cooking conditions as well as suitability of devices used for cooking. General cooking safety precautions need to be followed when the packs are used in ovens, as direct touch with heating elements and spillage of food contents on heating elements etc. can lead to safety hazards. Packing supplier/designer needs to ensure the requirements of perforations on the film to take care of any pressure build ups during cooking of food.
