After using the heat-shrinking packaging machine for a period of time, wrinkles will inevitably occur, which will affect the normal production. If this happens to the heat-shrinkable film packaging machine, the customer should not be too anxious. Contact the after-sales service, and the after-sales service will provide the customer with solutions. The following is a brief introduction of several solutions. I hope it can help you.

The appearance of wrinkles in packaging often occurs in shrink packaging, and there is no universal solution. The following issues are usually considered:

1. The shrinkage temperature is not enough.

Treatment method: increase the temperature (if there are many wrinkles on the upper part, increase the upper heating temperature, and vice versa); If the temperature is high enough, try to slow down the speed of the conveyor belt and let the product stay in the shrinkage tunnel for a longer time, which will improve the shrinkage effect.

2. If the problem still cannot be solved by the above treatment methods, will the quality of the shrink film be poor? If the shrinkage ratio is small and the toughness is not enough, it is only necessary to replace the shrinkage film.

3. If the problem still exists after the above treatment, it is the aging of the machine, or the machine used belongs to unqualified products, the temperature of the hot oven is uneven, and the flow rate of the hot air is too small. Replace with a high-quality heat-shrinkable packaging machine.

The above are some common problems and solutions. If you can't solve the problems for you, please contact the company's after-sales service in time.
