vings of up to 50 percent over conventional laminate structures, depending on the application, as well as energy savings, and consequently significantly improved life-cycle analysis results.
TripleBubble shrink films typically consist of a PET- or PA-based outer layer, a structural layer based on DuPont Surlyn and a PE-based seal layer, and can be enhanced with an EVOH or PVDC based barrier structure. Here, the partially cross-linked thermoplastic ionomer Surlyn is key to their high shrink, sof
