Medicine and their wide range of packaging forms have always been the focus of the pharmaceutical industry. Among many types of pill packaging, blister packaging undoubtedly occupies an important position, and the key equipment to achieve this packaging, the blister packaging machine, plays a pivotal role in the pharmaceutical and packaging industries.     Definition of blister packaging   Blister packaging, also known as blow molding packaging, is a form of packaging that uses a specific device to package products with a blister cavity made of plastic material. This form of packaging not only protects the product from damage, but also prevents the product from being contaminated.       Working principle of blister packaging machine   As a commonly used packaging equipment, its working principle is relatively complex but the process is clear and concise. Here are some descriptions of the basic working principle of the blister packing machine.     1. Blister Forming:   First, the packaging material is fed into the blister packaging machine, and through the heating system, we heat the plastic film to a sufficient temperature to soften the plastic film. Then, a specific mold is used to blow the heated plastic film to form a blister shell with a certain depth and shape. For particularly high depth requirements, a physical deepening device can also be added.   2. Filling the product:   After the blister shell is made, the product is automatically filled into each air blister by an automatic feeding and conveying system or manual feeding. If an automatic system is used, a precise positioning system is required during the feeding process to ensure that the product is accurately filled into each blister.   3. Heat-sealed packaging:   After the product is filled, the machine will place another layer of plastic film or paper material on top and heat-seal it through a heat-sealing system to protect the product between the two layers of material. It should be noted that the temperature and time of heat sealing have a great impact on the quality of the packaging. The general PVC temperature is set to 160 degrees Celsius because too high a temperature or too long a time may damage the packaging material, while too low or too short a time may cause the heat seal to be unstable.   4. Cutting shape:   Finally, each packaged product is cut out by the punching station to form an independent blister packaging product. This step also requires a precise positioning system to ensure the accuracy and neatness of the cutting. If there is a misalignment, the originally packaged material will be cut directly, and the entire outer packaging and product will be scrapped.   The operation process of the blister packaging machine needs to comprehensively consider multiple factors such as material properties, mold design, mechanical equipment and automatic control. Its working effect directly af...
