Sealing and shrinking machine after packaging wrinkles how to solve?

2019-02-12

After using the sealing and shrinking machine for a period of time, it is hard to avoid the appearance of wrinkles, so that it cannot achieve the preset packaging effect, but also affect the normal production. The following is a brief introduction of several solutions, hoping to help you.

Packaging wrinkles of the phenomenon, in the heat sealing and cutting shrink packaging machine often appear, there is no a universal solution, usually take into account the following problems.

1. Insufficient shrinkage temperature.

Method of treatment: turn up the temperature (if the upper part is wrinkled more, turn up the heating temperature; if not, turn down the heating temperature);If the temperature is high enough, try to slow down the speed of the conveyor belt, so that the product in the contraction of the tunnel for a longer time, will improve the contraction effect.

2. If the above treatment methods cannot solve the problem, is it possible that the quality of the shrink film is not good? If the shrinkage ratio is small, the toughness is not enough, you only have a good contraction film.

3. If the above treatment problems still exist, it is the aging of the machine, or the use of the machine is not qualified products, hot air passage temperature is not uniform hot air velocity is too small to replace good quality thermal shrinking machine.
