Alu Alu Foil
Alu alu foil, also called cold forming foil, or cold-form foil, is a kind of high barrier property of composite material, after cold stamping molding, can replace the PVC part of PTP blister packaging, which could greatly improve the protective for drugs(tablets,pills and capsules), extend the shelf life.
Alu alu foil is the best composite film of blocking performance at present with ultimate protection against water, oxygen and UV radiation.It is especially used for the high sensitive range of pharmaceutical and generic medicines which are highly hygroscopic or light sensitive.
