How to solve wrinkles after packaging by heat shrink packaging machine?
After the heat shrink packaging machine has been used for a period of time, it is inevitable that wrinkles will appear, so that the predetermined packaging effect cannot be achieved, which will affect the normal production. If this happens to the heat shrinkable film packaging machine, the customer does not need to worry too much, contact the after-sales service, and the after-sales service will provide the customer with a solution. Here are a few simple solutions, I hope to be of some help to you. The phenomenon of wrinkles in packaging often occurs in shrink packaging, and there is no one-size-fits-all solution. The following problems are usually considered: 1. The shrinkage temperature is not enough. Treatment method: increase the temperature (if the upper part has many wrinkles, increase the heating temperature, otherwise, adjust the heating temperature); if the temperature is high enough, try to slow down the speed of the conveyor belt, so that the time of the product in the shrinking tunnel is longer, will improve shrinkage. 2. If the above-mentioned treatment methods still cannot solve the problem, is it because the quality of the shrink film is not good? If the shrinkage ratio is small and the toughness is not enough, it is only necessary to replace the shrink film. 3. If the problem still exists after the above treatment, the machine is aging, or the machine used is an unqualified product, the temperature of the hot drying tunnel is uneven, and the hot air flow rate is too small. Replace with a good quality shrink wrapping machine.
