Aluminum foil is made of electrolytic aluminum with a purity of 99% and is made by rolling. Because aluminum foil has a highly dense metal crystal structure, it can completely block any gas, water vapor and light, so it can protect the packaged objects most effectively. Almost all applications in modern packaging require an opaque or high barrier layer, therefore it is widely used in pharmaceutical and food packaging.
The ptp aluminum foil appeared in some European countries in the 1930s. China first began to adopt foreign technology and introduced foreign equipment and raw materials in the 1980s. Medicines are packaged in various forms such as liquid, injection, tablet, granule, etc. Most of these packages use aluminum foil.
PTP aluminum foil is a sealing material sealed on a plastic hard sheet. It is generally made of 8011 aluminum foil, 8021 aluminum foil, and 8079 aluminum foil. The thickness is generally 0.02 mm. 8011 aluminium foil is often used mainly due to its mechanical properties, no pinholes, good roughness and glossiness.
8079 aluminum foil is an aluminum foil with high strength, good elongation and stretchability. In addition, it is of moisture resistance, air tightness, shading, abrasion resistance, fragrance preservation, non-toxic and tasteless. Therefore, 8079 aluminum foil is widely used in food packaging, pharmaceutical packaging, battery soft packaging and other fields.
1235 aluminum foil is an aluminum foil with an aluminum content of not less than 99.35%. This product is widely used in cables, tapes, batteries because of its excellent mechanical properties such as elongation and tensile strength, excellent anti-rust properties, formability and weldability. Haomei Aluminum can offer 1235 aluminum foil with a thickness of 0.006-0.2mm.
8021 cold form foil has strong mechanical properties, high blast resistance, strong puncture resistance and tear resistance; excellent moisture resistance, shading and extremely high barrier ability. More importantly, it passes multiple tests like mold and bacteria. Its heavy metal do not exceed 0.25ppm, strictly in accordance with industry standards to ensure safety and hygiene.
