Brief introduction of factors affecting the packaging effect of heat shrinkable film packaging machine

In order to improve the appearance of the product and improve the overall grade of the product, heat shrinkable film packaging machines have begun to be widely used. Whether in the electronics industry, the automotive industry or food, etc., heat shrinkable film packaging machines have begun to be used to package products. In the case of real shrinkage, the shrinkage effect is difficult to meet the packaging requirements. What are the factors that affect the shrinkage effect of the heat shrinkable machine? 1. The material of the shrink film is a factor that many customers tend to ignore. In most cases, the shrinking effect is not ideal, and customers focus on the shrinking machine to find problems. The quality of the film is the fundamental factor that affects the shrinkage effect. The same shrinking machine has the same temperature and speed. Experiments on the same package have found that the shrinkage effect of imported shrink film is much better than that of domestic shrink film. 2. The conveying speed of the shrinking machine: the current shrinking machines are all variable frequency speed regulation. The conveying speed of the shrinking machine can be adjusted according to the size of the product and the material and thickness of the film. Usually, when the temperature is constant, it can be improved by adjusting the speed. Shrinkage effect 3. Shrinkage temperature: According to different shrink films, the temperature adjusted by the shrink machine is also different. For example, the shrinkage temperature of PVC is 110~130 degrees, and the shrinkage temperature of pe film is 150~180 degrees. Even if it is the same shrink film, The quality of the film is different, and the shrinkage temperature is also different.

At the same time, as the recent research of Lead Machinery shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
