Polyethylene terephthalate (PET) : good barrier, strong chemical resistance. Polypropylene (PP) : Good heat resistance, suitable for high temperature sterilization. 1.2 Metal material of bubble cap: Aluminum foil: the most commonly used backplane material, excellent barrier, easy to open after sealing. Aluminum-plastic composite material: combining the advantages of plastic box aluminum foil. 2.
