1. Insufficient heat sealing temperature
In general, when the total thickness of the bag is 80~90 μ M, the heat sealing temperature shall reach 170~180 ℃; The total thickness of the composite bag with brE as the lining is 85~100 μ M, the temperature should be controlled at 180~200 ℃. As long as the total thickness of the bag is increased, the heat sealing temperature must be increased accordingly.
2. Too fast heat sealing speed
The sealing failure is also related to the speed of the sealing machine. If the speed is too fast, the sealing part is sent to the cold pressing part by the traction roller for cooling treatment before it can be heated, which naturally fails to meet the quality requirements of the heat sealing.
3. Improper pressure of cold pressing rubber wheel
There is one cold pressed rubber wheel above and below, and the pressure between them should be moderate. When adjusting the pressure, just clamp the spring.
4. There is a problem with the quality of the packaging bag
The failure of sealing is also related to the quality of the vacuum packaging bag. If the corona treatment of the composite lining is uneven and the effect is not good, and it happens at the sealing position, it must not be sealed. This situation is rare, but once it occurs, the product will be scrapped.
5. If there is moisture and dirt at the sealing of vacuum packaging bag, it will also cause poor sealing
In a word, to solve the problem of poor sealing of the first type, the heat sealing temperature can be properly increased, the heat sealing speed can be reduced, and the pressure of cold pressing rubber wheel can be increased.
