Simple Analysis Of Alu-Pvc Packaging Materials-aluminum Foil
Aluminum foil is usually used together with different kinds of plastic sheets , such as PVC or PS, PET, to pack and seal various tablets and capsules on aluminum-plastic blister machines. Since the pharmaceutical ingredients in many tablets or capsules are quite sensitive to air, moisture and light, during the packaging process, the packaging materials must be considered for their moisture-proof, mildew-proof, heat-proof, frost-proof, and light-proof characteristics to prevent light or moisture from damaging the active ingredients of the medicine or capsule, making it deteriorate or become invalid , and aluminum foil is non-toxic, odorless, good ductility, and has excellent properties in terms of moisture resistance, shading, and gas barrier. Aluminum Foil is widely used in packaging in the food and drug industry. However, it is not easy to make a real good aluminum foil packaging material. First of all, The number of pinholes on the surface of the aluminum foil must be controlled. Too many pinholes will damage the sealing performance and shading performance of the aluminum foil. At the same time, the thickness of the aluminum foil must be consistent. Only in this way can the adhesive be evenly applied to the aluminum foil. Surface, so that the aluminum foil and the plastic rigid sheet can be bonded more tightly during packaging.
