7-layer co-extruded film, BS-1955-03

7-layer co-extruded film, BS-1955-03

7-layer structure (inside to outside): ULDPE 100 µm (heat-sealing layer) / LLDPE 100 µm / adhesive polyolefin 20 µm / barrier layer 15 µm / barrier layer 15 µm / adhesive polyolefin 20 µm / polyester copolymer 50 µm (outer layer); total thickness 320 µm ±10%, adjustable on request

A 7-layer co-extruded film with a double barrier layer. The polyester copolymer outer layer gives better temperature resistance and stiffness than an all-polyethylene structure, suiting bags that need higher mechanical strength and a printable surface, while the ULDPE inner layer provides a clean, low-extractables heat-seal face.
