Development of blister packaging
In addition to all kinds of bottle packaging, blister packaging can be considered as the most commonly used packaging. Blister packaging has many advantages, it can provide patients with a single dose of drug packaging, convenient and economical. In addition, aluminum-plastic blister packaging protects the performance of the drug, which is fast in production, low in cost, small in storage space, light in weight, convenient in transportation, safe and reliable.
Because blister packaging has instructions printed on the surface, incorrect distribution of several tablets can be avoided. Therefore, blister packaging will become the main way of tablet and capsule packaging. The following is a brief introduction to the characteristics of pharmaceutical blister packaging and the problems that should be paid attention to in the printing coating.
Blister packaging is the most commonly used ideal packaging method in drug packaging. By aluminum foil, forming gravure and coating protection and heat seal, adhesive, rigid plastic drugs in the hole, mesh, shell and bubble formed by plastic film, can be moved hot seal blanking, to ensure the safety of the product. Blister packaging first appeared in Europe in the 1930s. In the 1980s, China began to introduce technology, equipment and raw materials, from monochrome printing, gradually developed into color multi-color series printing. Blister packaging is widely used in recent years, the fastest growth of flexible packaging materials, food, health products, pharmaceuticals and other fields of the main form of packaging. The main packaging materials of blister plastic are medical PTP aluminum foil, rigid plastic foil PVC and adhesive.
PTP medical aluminum foil is a kind of sealing material which is sealed on the hard medical plastic foil. The surface can print text or patterns, and the front and back have good printing performance. Aluminum foil is made of 99% electrolytes, calendering and other processing aluminum foil, non-toxic and tasteless, good electrical conductivity, light resistance, moisture resistance, etc. In modern packaging, almost all flexible composite packaging materials require high barriers or shading. All aluminum foil is used as a barrier material. This is because aluminum foil has a highly compact metallic crystal structure that is perfectly capable of blocking any gas.
