In the process of shrink packaging, some problems are often encountered, such as flatulence, atomization, fisheye and so on. These problems can be corrected by adjusting the machine Settings, the most commonly adjusted packaging machine temperature, circulating air speed, conveyor speed, the number of vents and shrink film size. The following heat shrink machine for you to introduce those common problems and treatment plans, I hope to help you! Thank you!

★ flatulence

The hot air is kept in a shrink film

Treatment method:

1. Increase the number of air vents to speed up the leakage of air from the shrink film

2, slow down the speed of the packaging machine conveyor belt, so that the hot air has a longer time to leak out of the shrink film

3, adjust the temperature of the packaging machine to help air leak out of the shrink film

★ Atomization

The surface of the shrink film becomes vague, like a mist

Treatment method:

1, reduce the temperature of the packaging machine, the temperature is too high is the cause of shrinkage film atomization

2. Adjust the speed of the conveyor belt of the packaging machine to reduce the contact time of the shrink film

★ Weak sealing line

The sealing line of the shrink film is easy to break or show small holes.

Treatment method:

1. Lower the temperature of the sealing machine hot sealing knife

2, the sealing line height is not correct, the sealing line height should be half of the height of the packaging

3. The pressure of the sealing frame is not uniform, although the degree and position of the sealing frame should be adjusted

4, the hot sealing knife or sealing base may become dirty, clean the hot sealing knife or sealing base

5. If the heat insulation pad or heat insulation sticker of the sealing base is damaged, the heat insulation pad or heat insulation sticker can be replaced

6, the sealing time is too short, the sealing pressure in the sealing line is not completely separated before disappearing, you can adjust the sealing time
