Common Problems And Treatment Of Stretch Film1

There will be no quality problems in the normal use of stretch film, but if we do not pay attention to the use or preservation process, it is easy to lead to product problems, if not adjusted in time, it will affect our normal use, next, we will analyze several common problems and treatment methods:

First, the phenomenon of falling film

There are many factors that cause the film to drop under the stretch film, including the width of the film is too narrow, the chain is not tight, the film is biased and other factors.

Solution: We can cut its lower membrane to make its width wider to ensure that it matches the width of the chain. We can also adjust the position of the lower membrane to make the center of the lower membrane coincide with the center of the chain.

Two, the phenomenon of poor molding effect

The main factors causing the poor forming effect of stretch film are heating plate heat is not enough, heating temperature does not match, high temperature or low temperature.

Solution: repair heating plate, make it normal heating, ensure the full supply of heat; Reduce or increase the temperature of the heating plate, adjust the temperature of the heating plate to the appropriate temperature range; Choose appropriate specifications for stretching, heavy stretching using thicker film, light stretching using thinner film.
