The laminates required to meet the requirements in this area are very often constructed as 2, 3, or 4 ply laminates with combinations of PET, OPA, OPP, CPP, aluminum, and various types of PE with or without barrier.
In all cases there is a laminate designed to meet the requirements of the individual customer.
