Why Can't Stretch Film Be Overheated And Stretched?

Although stretch film is a packaging product used in many industries, we must have a lot of troubles when using stretch film. For example, when the stretch film is packaged, the stretch film is originally packed It's still good, but after a period of time after the packaging, it is gradually torn or the molding quality is poor. Why is this?

If we heat the stretch film before packaging, it may be caused by the insufficient heating of the heating plate or the mismatch between the heating temperature and the stretch film. When it is too high, the film sticks to the heat sealing plate. On the other hand, if the haze of the film is increased, the stretch forming will appear partially thin. When the heating temperature is too low, the heating temperature of the film is too low, the stretching temperature of the film cannot be reached, and there are many breakages after stretching. If it is not stretched after heating with a heating plate, it may be caused by excessive stretching.

If the above situations occur, we can divide them into different types to deal with. If it is because of the problem of the heating plate, we can solve the problem of the heating plate first. If the heating capacity is not enough, we need to repair the heating plate first. , so that it can be used after normal heating, which can ensure the normal supply of heat. Secondly, if the heating plate is overheated, the temperature of the heating plate can be adjusted to keep it within a normal and appropriate range. The deep stretched film is stretched with a thicker film, and the shallow stretched film is stretched with a thinner film. The film is stretched, which not only ensures the quality of the product, but also reduces the production cost.
