Almost all products in modern packaging that require opaque or highly-barrier composite materials use
aluminum foil as the barrier layer. This is because
aluminum foil has a highly dense metal crystal structure that can completely block any gas.The
aluminium foil for pharmaceutical packaging will account for about 60% to 70% of the future pharmaceutical tablet and capsule packaging, which is one of the most promising pharmaceutical packaging materials at present.The quality of Chinese pharmaceutical
aluminium foil is a little lower than that of the international top level. It is reflected that there are two main problems:1. The number of pinholes in medicinal
aluminum foil is far from meeting the requirements. The pinhole of
aluminum foil is a defect of penetration performance, which affects the barrier performance of
aluminum foil, especially for pharmaceutical packaging. It is easy for oxygen, water vapor, and light to penetrate and reduce the drug's efficacy.The national standard of pharmaceutical foil requires that the pinhole diameter is not more than 0.3mm, and the diameter of 0.1 - 0.33mm cannot be more than 1 per square meter. At present, domestic
aluminum foil rarely meets this standard.2. The thickness of medicinal
aluminum foil is uneven, and the tensile strength is low. Due to the uneven thickness of the
aluminum foil, it will make the the adhesive coating amount difficult to reach the standard during the mechanical coating process of the PTP
aluminum foil, and then affect the combination of the
aluminum foil and the polyvinyl chloride hard sheet.In addition, it also will lead to the break of
aluminum foil after the tension is applied in the actual processing.As a professional manufacturer of
aluminium foil for medicine packaging, Haomei Aluminum digs in on the improvement of the manufacturing process. Now it has 10 sophisticated foil rolling mill instruments and equipment to ensure the stable output of medicinal
aluminum foil.The produced medical
aluminum foil is flat, safe, hygienic, clean, uniform in color, no pinholes, no oil stains,etc. And the heavy metal does not exceed 0.25 parts per million. Haomei pharmaceutical
aluminum foil is strictly in accordance with industry standards. Welcome to contact us if you need.
