Due to the unique advantages of blister packaging, it has developed rapidly and extended to the outer packaging of injection boxes and medicines, health care products, and even food, cosmetics and other packaging fields. It has become the most important packaging form for future medicines and health care products. The main materials of blister packaging are pharmaceutical blister aluminum foil, plastic hard sheet (polyvinyl chloride PVC) and adhesive.
Aluminum foil is mainly used in the blister packaging of tablets or capsules in pharmaceutical packaging, which not only has good barrier properties, but also is easy to puncture and administer. Blister packaging is made by filling the drug into the hole made of plastic, and then heat-sealing the plastic hard sheet with aluminum foil coated with protective agent and adhesive. Aluminum foil tablet packaging can quickly complete the processes of printing, protective layer coating, adhesive layer coating and drying in one equipment, which is very suitable for mass production.
The aluminum foil material for pharmaceutical packaging is made of electrolytic aluminum with a purity of 99%, which is made by calendering. It is non-toxic, odorless, has excellent electrical conductivity and light-shielding properties, and has extremely high moisture resistance, gas barrier properties and taste retention. 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.
8011 aluminum foil is one of the pharmaceutical packaging materials with good development prospects at present. As a sealing material sealed on a plastic hard sheet, it has the advantages of high cup convexity, high heat-sealing strength, no holes, good sealing performance, and strong light-shielding performance. Compared with bottled tablet medicines, drug blister packaging has the biggest advantage of being easy to carry and can reduce the pollution of medicines during carrying and taking. The size and number of pinholes in aluminum foil have a decisive influence on the moisture resistance, gas barrier and light shading properties of aluminum foil and its composite materials. Aluminum foil should not have dense, continuous, and periodic pinholes; in each square meter, pinholes with a diameter greater than 0.3mm are not allowed, and the number of pinholes with a diameter of 0.1~0.3mm must not exceed 1.
