1. Does the raw material have heat sealing properties?
In the medical blister bubble industry, the preferred material for medical use and hot pressing properties is PETG, followed by PET modified material GAG. The reason why the sealing is not strict, it is necessary to exclude whether PET is used, because PET itself has poor hot pressing performance, and it is highly likely that the heat sealing strength is insufficient.
2. Is the heat-sealed mold uneven or damaged?
When heat sealing dialysis paper medical blister blister, heat sealing mold is needed. Place the blister pack in the heat seal mold and seal the dialysis paper. If the surface of the heat-sealed mold is not flat or other abnormalities occur, it is highly likely that the hot pressing in a certain area is not strict.
3. Heat sealing machine parameters setting
The blister blister for different materials and thicknesses is heat-sealed with different types of dialysis paper, and the sealing time, temperature and pressure value settings are different.
The above three points are the reasons for our analysis of this situation, for reference, more details, you are welcome to consult the contact phone at the top of the website at any time, we will be happy to provide you with detailed services!
