In pharmaceutical production, when a blister packaging machine is used for packaging products, common molding base film materials are polyvinyl chloride (Polyvinyl chloride, hereinafter referred to as "PVC") and polyvinylidene chloride (Polyvinylidene chloride, hereinafter referred to as "PVDC"), however, the two materials, namely the PVC and the PVDC, have strong pollution, can cause environmental pollution, and can also cause harm to human bodies. Accordingly, pharmaceutical enterprises are seeking new alternatives. Polypropylene (PP) is a powerful candidate, and PP materials are easy to recycle and do not release toxins when incinerated. In addition, if the sealing cover film is made of PP material, the performance of the sealing cover film is equivalent to that of an aluminum foil sealing layer, and the sealing cover film can be easily uncovered like a common aluminum foil so as to be convenient for a user to take out medicines. However, there are still difficulties in the prior art with respect to the processing of PP materials for use in blister packaging.
