At ordinary times, when you buy, an important thing is to see the quality, especially the medical blister tray. When purchasing, we should pay more attention to material problems, such as PVC can not be used as food blister, pet can not be used in microwave oven and so on. Moreover, when purchasing medical blister trays, the requirements are higher than those of ordinary blister. There are certain requirements for sterile production and dust-free workshops, and they are very strict with the operators. Please pay attention to the following points when purchasing medical blister pallets: 1. Pay attention to the workshop of blister packaging manufacturers, with a dust-free workshop of more than 100000 or millions. 2. Environmentally friendly sheets must be ***ed to meet the certification of iso100993 and iso11607, so as to ensure that the packaging will not be affected after contacting the equipment. 3. Aluminum film processing is ***ed, because the mold produced by copper mold will increase mold, and only the medical blister tray produced by aluminum alloy is relatively safe.
