30. UV resistance of aluminum foil: tests the ability of aluminum foil to resist aging or fading caused by ultraviolet radiation.
Polyvinyl chloride material itself is non-toxic, but polyethylene monomer has liver cancer-causing effects, so when using it, it is necessary to pay attention to the fact that the polyvinyl chloride monomer content of PVC sheets used for pharmaceutical packaging should be controlled within one part per million; on the other hand, polyvinyl chloride material has poor heat resistance and is easily deformed by heat. It is often necessary to add stabilizers and plasticizers to lower the processing temperature and adjust the hardness of PVC. Non-toxic additives should be selected for medicinal hard PVC sheets.
