The following Teng Yi intelligent to introduce this type of heat shrink packaging machine solution, I hope to help you. The situation of wrinkling in the packaging of the heat shrink packaging machine often occurs in the folding packaging, and there is no one all-around treatment method. Generally, due consideration is given to such difficulties as the following.

1, check whether the shrinkage temperature is not enough.
Treatment method: Increase the temperature (if the upper part is wrinkled, increase the heating temperature, and vice versa, adjust the heating temperature); If the temperature is high enough, you can try to slow down the speed of the conveyor belt, so that the product in the contraction tunnel for a longer time, the contraction effect will be improved.

2, if the above treatment method still can not solve the problem, you can try to replace the heat shrink film, to see if it is the quality of the film, if the shrinkage proportion is small, toughness is not enough, it is recommended to replace the better heat shrink film.

3. If the problem still exists after the above treatment, it is necessary to consider whether the machine is aging, or whether the machine used is a substandard product, the temperature of the hot dryer is uneven, and the hot air flow rate is too small. It is recommended to replace it with a good quality heat shrink packaging machine.
