Polyamide Film/Aluminum/PVC Hard Double Aluminum
Cold stamped aluminum is one of the composite materials with the best barrier properties. It adopts a composite structure of PA/AL/PVC. The aluminum foil in the middle can 100% isolate water vapor, oxygen, and ultraviolet rays. Therefore, it is specially used to make blister packaging for medicines. Cold-formed aluminum can reliably maintain the stability of drug efficacy and effectively extend the shelf life.
