Blister packaging is one of the main forms of pharmaceutical packaging and is suitable for automated packaging of tablets, capsules, pills, suppositories, and powders. The blister material is filled with medicine in the blister cavity formed by thermoforming or cold stamping, and then the covering material such as aluminium foil blister packaging is heat-sealed with the formed blister material under certain temperature, pressure, and time conditions to form a packaging form.
The aluminum foil covering the blister cavity plays the role of sealing and carrying text and graphic information. It is the inner label of the medicine and a component of the blister packaging system.
There are five types of aluminum foil for medicine packaging:
1. Ultra-light gauge foil is soft tempered with a thickness of 0.006-0.007 mm.
2. Light gauge foil is soft tempered with a thickness of 0.008-0.012 mm.
3. Aluminum packaging foil is soft tempered with a thickness of 0.02-0.05 mm.
4. The thickness of aluminum blister foil is usually 0.012-0.025 mm.
5. Aluminum cold forming foil is soft tempered with a thickness of 0.045-0.06 mm.
The raw material used to produce PTP aluminum foil is industrial pure aluminum foil, which is generally required to have a thickness of 0.02mm, a tensile strength of 98kPa, a burst strength of 90kPa and a surface wetting tension of not less than 32.
The pinhole requirement for aluminum foil for medicinal and health food is that the pinhole with a diameter of 0.1-0.3mm should not exceed 1/m2. Since the pinhole in the aluminum foil is a penetrating defect, the health food and medicine will be reduced or deteriorated by oxygen, water vapor and light, so the pinhole requirement is very strict; in addition, if the thickness of the aluminum foil exceeds the required deviation (10%), it will affect the coating amount of the adhesive layer and the protective layer.
8011 ptp blister foil is a hard PTP aluminum foil used for pharmaceutical packaging. 8011 aluminum foil has the advantages of high cupping value, high heat sealing strength, no pinholes, good sealing, etc.
