The shrinkage effect of the Stretch Film determines whether the packaging effect of the stretch film is good or not. Therefore, when purchasing the stretch film, the user must test the shrinkage effect of the stretch film. What we want to explain to you today What are the factors that affect the shrinkage effect of the stretch film? The specific content is as follows: 1, the temperature is not enough Each kind of stretch film has its adaptable temperature, especially stretch film with a large shrinkage ratio, which has higher requirements for temperature, so the suitable temperature is the main factor that determines the shrinking effect. 2, speed After the temperature is reached, the speed is adjusted. If the speed is too fast, the stretched film does not shrink well, and the speed is too slow, the stretched film will be scalded. Therefore, the matching speed is another difference in the shrinkage effect of the shrinking machine. A big factor. 3. The direction of the wind The direction of the wind determines the position where the surface of the product is heated, which is especially important for the cuff-type shrink packaging machine. The position of the cuff requires a higher temperature, so the adjustment of the wind direction of the shrink machine is very important.
