The inner packaging of tablet packaging refers to the packaging that is in direct contact with the drugs, such as aluminum foil. The inner packaging should be able to ensure the quality of the drugs during production, transportation, storage and use, and be convenient for medical use. Changes in the inner packaging materials and containers of drugs should be subject to stability tests based on the materials of the selected drug packaging materials and containers to examine the compatibility of the drug packaging materials and containers with the drugs.
Compared with bottled tablets, the biggest advantage of blister packaging is that it is easy to carry and can reduce the contamination during the carrying and taking of drugs. However, as patients who take drugs regularly, there is a large single dose, which makes the unit cost of blister packaging significantly higher than that of bottled drugs. Some pharmaceutical companies usually choose blister packaging for drugs with higher prices, high technical content and new varieties.
The materials used in blister packaging are mainly PTP aluminum foil and plastic hard sheets, which are mostly used to package tablets, pills and capsules. Blister lidding foil is a sealing material sealed on plastic hard sheets. It uses hard industrial pure aluminum as the base material and has the characteristics of non-toxicity, corrosion resistance, impermeability, heat resistance, moisture resistance, light resistance and high temperature sterilization. Plastic hard sheet materials usually use polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) or composite materials. They have good barrier properties against water, steam and light.
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. In addition, PTP aluminum foil can also be customized according to the needs of different drugs. 8011 aluminum foil is used to make PTP aluminum foil with a thickness of 0.016-0.04mm.
First of all, PTP aluminum foil manufacturers will use high-purity aluminum alloy as the base material, usually requiring a pure aluminum content of more than 99.9% to avoid any potential contaminants affecting the quality of the medicine. High-purity aluminum alloy not only has good barrier properties, can effectively prevent oxygen, moisture and light from invading the medicine, but also ensures that no harmful substances are released during the heat sealing process, maintaining the chemical stability of the medicine.
Secondly, in order to further improve the hygiene standards of packaging, aluminum foil manufacturers will also perform special treatments on the surface of aluminum foil, such as spraying a moisture-proof layer or coating with food-grade coatings. These treatment layers also need to meet strict food hygiene standards to ensure that there is no odor and that the original properties of the medicine are not affected.
In addition, when purchasing raw materials, PTP aluminum foil manufacturers will strictly review the qualifications of suppliers and give priority to partners with international certification, good industry reputation and stable supply chain.
In summary, Haomei Aluminum has set strict raw material selection standards to not only ensure product purity, but also provide a hygienic and reliable barrier for drugs. Welcome to inquire pharma foils from it.
