What Are The Reasons Why The Sealing Machine Cannot Heat Seal?

1. Please check whether the sealing film is installed upside down. Installing the sealing film upside down is a small mistake that many users often make;

2. Please check whether the heat sealing temperature has reached (about 150~200℃). Note that the heat sealing temperature of sealing films of different materials is different, and the heat sealing temperature of sealing films of different thicknesses is also different;

3. Check whether the sealing speed is too fast. If you do not know how to set it or find any abnormality, please contact the sealing machine manufacturer in time. Generally, semi-automatic or fully automatic sealing machines can set the sealing speed, and the manufacturer will set it according to the needs of users;

4. Please check the installation quality of the upper and lower molds, because some parts may become loose during the logistics transportation process;

5. Please check whether the material of the sealing film is consistent with that of the container (cup/box/bowl) to be sealed. Different materials of the two will also affect the sealing effect. For more relevant introductions, please refer to "About the Selection of Sealing Film".
