Application Of Aluminum Foil Blister Medicine Material
The drug packaging of aluminum foil blister is also called blister packaging, also referred to as “PTP” (Nhấn qua bao bì). This type of packaging has many advantages: Đầu tiên, it provides patients with multiple doses of drug packaging, thật tiện lợi và tiết kiệm. Second, the aluminum-plastic blister packaging has good drug protection performance, fast production speed, giá thấp, and storage space. Small, nhẹ, and easy to transport. Thirdly, the safety is good. Because the blister packaging aluminum foil is printed on the surface of the text, the dispenser can avoid the occurrence of wrong drugs during the dispensing process of multiple tablets.
With the “rising star” such as aluminum foil packaging, my country and the world will greatly increase high-quality blister packaging in a period of time to meet the needs of the pharmaceutical market. It is expected that packaging used for pharmaceutical blister materials will account for About 60%-70% of the pharmaceutical tablet and capsule packaging in the future is one of the pharmaceutical packaging materials with the best development prospects.
This article shares some of the development directions of blister packaging and “PTP” materials in the future based on the current domestic use of pharmaceutical foils, pharmaceutical polyvinyl chloride (PVC), adhesives and gravure inks. Most of the data comes from Internet, if there is any infringement, please contact me to delete it.
1.The materials used in aluminum foil bliste packaging also have many fine requirements.
The aluminum foil used in the pharmaceutical blister pack is a sealing material sealed on a hard piece of medicinal plastic polyvinyl chloride (PVC), so it is also called a lidding material. The aluminum foil is made of electrolytic aluminum with a purity of 99% and is made by rolling. Nó không độc hại, không mùi, 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 block almost any gas, hơi nước và ánh sáng, so it can protect the packaged objects most effectively. In modern packaging, almost all require opaque or high barrier layer, so it is widely used.
2. The most widely used blister material for pharmaceutical packaging is medicinal polyvinyl chloride (PVC) rigid sheet.
Since medicines are very sensitive to moisture and light penetration, it is necessary to have good barrier properties against water vapor, light and peculiar smell to the plastic hard film. Tuy nhiên, the currently used polyvinyl chloride (PVC) is just not ideal on the wet and humid side, so it should be promoted in the future.
Polyvinylidene clorua (PVDC) or its composite materials. The characteristics of polyvinylidene chloride are: high polymer density, regular structure, high crystallinity, so it has extremely strong gas and gas sealing, chống ẩm tuyệt vời, good oil, chemical and solvent resistance. Especially it has excellent barrier properties to oxygen, water vapor and carbon dioxide in the air, such as polyvinylidene chloride hard film, and other plastic composite materials PVC/PVDC/PE/PVDC/0PP/PE, PVC/PE, vân vân. The brown composite plastic flakes are widely used in the blister packaging of medicines.
3. Dược phẩm “PTP” aluminum foil printing ink material.
Hiện tại, there are many types of printing inks on the market, with different brands. Tuy nhiên, considering the printing process of medicinal “PTP” aluminum foil and the special requirements of pharmaceutical packaging, the printing ink must have good adhesion to the aluminum foil, the printed text pattern is firm and clear, the application of solvent release, and good heat resistance. Excellent friction resistance, good gloss, non-toxic pigments, no contamination of the packaged drugs due to the migration of chemical components in the ink, and the practical viscosity should meet the process requirements of aluminum foil printing.
