Pharmaceutical aluminium foil price china

The pharmaceutical aluminium foil price china is affected by the alloy, temper, specification, market demand and the aluminum ingot cost. Haomei supply 8011, 8021, 8079 pharmaceutical grade aluminum foil for medicine storage and packaging. Pharmaceutical aluminum foil is mainly used for processing blister packaging, so it is also called as aluminum blister foil or blister aluminium foil.

For making medicine blister, the pharmaceutical aluminum foil is just a base material, it still needs other material for lamination. The largest amount of blister packaging material is a medicinal PVC hard sheet. Because the drug is sensitive to moisture and light transmission, PVC rigid sheets are required to have good barrier properties of moisture, light and odor. However, the PVC currently used is not ideal for moisture resistance, so it should be in the future. Advocating the use of polyvinylidene chloride (PVDC) or its composite materials, PVDC characteristics are: high molecular weight, high density, structural structure, excellent moisture resistance, good oil resistance, drug resistance and solvent resistance, especially oxygen, water vapor, and carbon dioxide gas in the air have excellent barrier properties. In the case of the same thickness, the barrier performance of PVDC to oxygen is 1500 times that of PE, 100 times that of PP, 100 times that of PET, and the water vapor resistance and oxygen are better than PVC. In addition, the sealing properties, impact strength, tensile strength and other indicators of PVDC materials can meet the special requirements of pharmaceutical packaging, and it is the development focus of pharmaceutical packaging materials in the future. In addition, other composite materials, such as PVC/PVDC/PE, PVDC/OPP/PE, PVC/PE, etc., are also widely used in blister packaging of pharmaceuticals.
