Why can't the cup sealing machine seal the mouth?

The main reason why the manual sealing machine can't seal is that the surface temperature of the sealing ring is too low, which leads to the failure of hot pressing sealing of the film. After long-term use, carbide or impurities are attached to the annular surface of the seal, which leads to poor hot pressing effect, lax sealing and easy opening. The heating switch of the sealing machine failed, and the manual sealing was unstable.

The milk tea sealing machine is small in size and is one of the instruments commonly used in milk tea shops and beverage shops. Milk tea sealing machine can be divided into manual type and automatic type. The milk tea sealing machine should be used at the same time as the sealing film, which is suitable for sealing cups, plastic cups, plastic bowls, paper cups and paper bowls.
