PET and polyolefins, such as PE, PP or ionomers, between PO and PA and between PA and the heat-sealing layer. As a result, DuPont has developed a standard tie layer range, providing resistance during the production process, matching the viscosities of other polymer types used and adhering well to the two substrates during orientation and after thermal relaxation. This range includes DuPont Bynel 21E787 and 22E780, which are suitable for PET/PO, or Bynel 41E687, which is suitable for PA/PO, with
