Moisture-proof And High-sealing Pharmaceutical Packaging Aluminum oil
Aluminum foil is a widely selected material for solid pharmaceutical packaging materials, and it is also one of the materials with the best packaging effect. With the advancement of technology, people hope to make further progress in the material preparation of aluminum foil for pharmaceutical packaging, so as to improve the moisture resistance and sealing performance of aluminum foil packaging for pharmaceutical use. Specifically, it is to improve the moisture-proof and high-sealing properties of solid medicines such as tablets and capsules that are sensitive to water vapor and oxygen by the aluminum foil for medicine packaging.
The pharmaceutical packaging material industry is an emerging industry. With the use and development of aluminum foil for medicinal purposes, the industry has developed faster since the beginning of the new century. Today, with the emergence of new products and new drugs, the market space of the pharmaceutical packaging industry is broad and the prospects are very attractive. The blister aluminum foil packaging used for solid medicines such as tablets, pills, capsules, and suppositories is also called PTP packaging because it has the advantages of good stability in protecting medicines, fast production speed, lightweight, convenient transportation, and easy portability. It is widely used in a small doses and serialized pharmaceutical packaging.
Then came the cold alu alu foil, aluminum strip foil, tropical blister foil, medicine PVC/PVDC. and many other new pharmaceutical packaging aluminum foil materials.
As an important part of tropical aluminum blister packaging, aluminum foil for medicinal packaging is in increasing demand, and consumers have higher and higher requirements for it, and aluminum foil with poor performance will be gradually eliminated. The aluminum foil blister packaging of solid drugs such as tablets, pills, capsules, and suppositories is the continuation of drug production and the last process for drug reagents. As a packaging material or container that directly contacts drugs, it is an organic component of drugs. Especially for some sensitive pharmaceutical products that are easily deteriorated when exposed to moisture, easily oxidized when exposed to oxygen, and easily decomposed when exposed to light, the packaging materials of these products not only require good barrier properties against moisture and oxygen, but also require protection from light, and To have good machinability and eye-catching color. Most of the existing aluminum foil for pharmaceutical packaging has poor tensile properties, and its breakage rate is very high after molding, so it is impossible to talk about sealing and barrier properties. Therefore, moisture-proof and high-sealing aluminum foil for medicinal packaging has become extremely important.
The purpose of this utility model is to provide a moisture-proof and high-sealing type aluminum foil for pharmaceutical packaging, which has a reasonable structure design, has good stretching and heat-sealing properties, is non-toxic and environmentally friendly, and is resistant to water vapor, oxygen and has good light-blocking performance and is very suitable for packaging sensitive pharmaceutical products, which means that this packaging material can effectively maintain the efficacy of drugs for a long time and prolong the shelf life of drugs. To achieve this high-sealing medicinal packaging aluminum foil, the original preparation method needs to be improved, and a new medicinal packaging preparation method is applied. The moisture-proof and high-sealing aluminum foil for pharmaceutical packaging include an aluminum foil substrate layer. The aluminum foil substrate layer is formed by superimposing and pressing multiple layers of double-zero aluminum foils. The upper surface of the aluminum foil substrate layer is provided with a high-barrier Performance PVDC six-layer co-extrusion cast film layer, the lower surface of the aluminum foil substrate layer is provided with an LLDPE (linear low-density polyethylene) film layer.
Compared with the existing packaging aluminum foil preparation technology, the structure design of the aluminum foil for pharmaceutical packaging is reasonable and ingenious, and the practicability is strong. Water vapor, oxygen, and light have high barrier properties, especially suitable for packaging sensitive pharmaceutical products, which can effectively ensure the efficacy and dosage of the packaged drugs, so it has the advantages of safety, convenience, and long shelf-life;
By combining the water-based VC adhesive tape set on the inner layer with the LLDPE film layer, the heat sealing efficiency and yield of the aluminum foil for pharmaceutical packaging are effectively improved, and the oxygen barrier, moisture barrier, and barrier properties of the aluminum foil for pharmaceutical packaging are effectively guaranteed. Light sealing properties.
