Comparison of PET-A, -G, -GAG, -S, -BO
The various PET-types are differ in theirs ability of deep drawing and theirs gas permeability. PET-G, -A, -S and the combinations are used for deep drawing. By contrast the biaxial oriented PET is more heat resistant. That is the reason, that the PET-types be selected per application and properties. In some cases the PET-types are used in combinations.
