Shrink wrap machine troubleshooting

I believe that many consumers are not very understanding of the shrink packaging machine, but familiar with for the heat harvesting film, the heat shrink packaging machine can also affect the aesthetics of the heat shrink film, then what is the common troubleshooting of the shrink wrap machine?

Flying: Hot air remains in the shrink film

solution:

1. Increase the amount of breathable hole to speed up the air from the shrink film
2. slow down the conveyor speed of the package, so that the hot air has a longer time from the shrink film
3. the temperature of the packaging machine helps the air leak out from the shrink film

Atomization: The surface of the shrink film becomes blurred, like a mist.

solution:

1. Turn down the temperature of the packaging machine, the temperature is too high, the cause of the injection film atomization
2. adjust the conveyor speed of the packaging machine, reduce the time when the shrink film is in contact with heat

Fish eye: the surface of the fish eye wrinkle

solution:

1. The temperature of the heat shrink packaging machine is too low, and the temperature of the packaging machine can be increased.
2. the speed of the heat shrink packaging machine is too fast, and the speed of the conveyor belt can be lowered.
3. the circulating wind power of the heat shrink packaging machine is too low, and the circulating wind is lowered.

Fish line: a series of wrinkles appear in the corner and edge of the shrink film

solution:

1. too much breathable hole on the shrink film, causing air from the shrink film too fast, the shrink film is not completely contracted, and the amount of breathable hole can be reduced.
2. the speed of the heat shrink packaging machine is too fast, and the speed of the conveyor belt can be lowered.
3. The temperature of the heat shrink packaging machine is too low, and the temperature of the packaging machine is increased.
4. The circulating wind power of the heat shrink packaging machine is too low, and the circulating wind is lowered.

Dog ear: the corner of the assembly of the film into a highly protruding triangle.

solution:

1. The shrink bag of wrap the packaging is too large, and the shrink bag is small.
2. the speed of the heat shrink packaging machine is too fast, and the speed of the conveyor belt can be lowered.
3. the circulating wind power of the heat shrink packaging machine is too low, and the circulating wind is lowered.
4. The temperature of the heat shrink packaging machine is too low, and the temperature of the packaging machine can be raised.

Crushed package: packaging to shrink the shrink film to deformation or crushing

solution:

1. The temperature of the heat shrinkable packaging machine is too high, and the temperature can be lowered.
2. The speed of the heat shrink packaging machine is too slow, and the speed of the conveyor belt can be increased.
3. the shrink bag of wrap the package is too small, and the shrink bag is large.
4. the shrinkage shrinkage tension used is too large, not suitable for the packaging, the use of lower shrinkage tension shrink films

Broken hole: the surface of the contraction film has broken hole

solution:

1. the penetrating air hole is torn and inspect the penetration of the sealing machine
2. the amount of breathable hole is insufficient, increase the number of gas permeable holes
