Medical aluminum foil bag packaging is a type that is widely used in daily life. Today, we will take drug packaging as an example to analyze how strict the material selection requirements are for drug packaging materials. Common drug packaging forms on the market generally include granule, powder, tablet, and liquid drug packaging. Next, we will discuss the material selection requirements for granule, powder, and tablet drug packaging.

Medical aluminum foil bag_ Selection of Pharmaceutical Packaging Materials

Pharmaceutical packaging for granules and powders. In most consumers' daily use of drugs, bagged granules and powders that are easy to dissolve and take are two common types of drugs. From the perspective of packaging materials and forms for granules and powder drugs, with the progress of packaging technology and the development of equipment, the medical aluminum foil bag packaging material with multi-layer aluminum plastic composite film has become the primary choice for drug packaging materials due to its excellent barrier performance and outstanding moisture-proof effect. Let's observe from the perspective of technology and equipment. In the national standard "Aluminum Foil for Pharmaceutical Packaging", there are clear requirements for the surface quality of printed text on pharmaceutical aluminum foil, as well as physical and chemical indicators for the performance of the protective layer and adhesive layer, to protect the pharmaceutical PTP aluminum foil from good barrier performance, hygiene and safety, heat sealing performance, and good physical and mechanical properties. To achieve the above performance in the PTP aluminum foil printing and coating production process, it is still necessary to be familiar with the performance of the raw materials used. How to control the heat sealing temperature of particle and powder drug packaging, how to control the filling amount of drugs, and how to test the sealing degree of bag packaging have become important issues that drug manufacturers must pay attention to. Firstly, the control and resolution of packaging heat sealing issues should fully consider the heat shrinkage ratio of packaging materials, as well as the number of layers and materials of composite packaging films.

If the execution temperature of the heat sealing process is too high and the shrinkage ratio is too large, it will cause wrinkles at the edge of the heat sealing. If the heat sealing temperature is too low and the composite film is thick, it will lead to loose packaging sealing. Therefore, in order to achieve good sealing effect quickly and effectively, it is necessary to combine the packaging material details provided by drug packaging material suppliers, as well as relevant parameters such as shrinkage ratio, and achieve sealing based on the characteristics of technology and equipment.
