Compared with bottled tablets, the biggest advantage of blister packaging is that it is easy to carry and can reduce the pollution during the carrying and taking of medicines. The materials used for aluminum blister packaging are mainly PTP pharmaceutical aluminum foil and plastic hard sheets, which are mostly used to package tablets, pills and capsules.
The core value of PTP aluminum foil lies in its moisture and oxygen resistance. Thanks to the compact structure and excellent barrier properties of aluminum itself, PTP aluminum foil can ensure that drugs are not damp or oxidized during storage and transportation, maintain stable efficacy, and extend the shelf life of drugs.
This feature is particularly important for drugs that are sensitive to moisture and oxygen, such as biologics, easily degradable drugs, or tablets and capsules containing water-soluble ingredients. It is a key barrier to ensure that patients use medicines safely and have good efficacy.
On the technical level, the production of PTP aluminum foil integrates precision coating, composite processing and molding technology, and each link needs to be strictly controlled to ensure the high quality of the product. PTP medicinal aluminum foil alloy is usually 8011-H18 or 8011-O temper. The thickness is of 0.016-0.04mm.
PTP aluminum foil testing is a method for quality inspection of pharmaceutical packaging materials. PTP aluminum foil is a material commonly used in pharmaceutical packaging, with advantages such as moisture retention, gas and light barrier. It is mainly composed of aluminum foil and glue layer, which can effectively protect the quality and safety of drugs.
The pinhole requirement for aluminum foil used for medicine and health food is that the number of pinholes with a diameter of 0.1-0.3mm should not exceed 1/m2. Since pinholes in aluminum foil are penetrating defects, the health food and medicine will be reduced in efficacy or deteriorate when oxygen, water vapor and light penetrate into them, so the pinhole requirement is very strict.
