A Method of Identifying the Quality of stretch film

The products directly sold by stretch film manufacturers can be used in many industries. In order to ensure the stable performance of the stretch film, it is necessary to test them. Now let's have a close look at them.

The pallet stretch film and the plastic coated silicon are stripped off, and the side of the mask is coated with glue. The glue is tightly bonded with the adhesive and then pulled away. The glue thread stretched between the glue and the glue can not be more than 0.2 millimeters long, so that the stretch film is less likely to be degumming when used. The thickness of the stretch film is also important because it is related to maintenance. The impact force of the film, usually the thickness of the stretch film is about 9 wire. If necessary, the thickness of the stretch filmshould be added correspondingly, otherwise it will be damaged and damage the processed object.The pallet stretch film can be measured by micrometers. It is not easy to grasp accurately by visual measurement and hand touch. Because the diameter of a hair is about 7 silk, it is hard to get the sensitivity of hand feeling. Some people weigh the weight of each volume by weighing scales. Actually, the maintenance of the bottom paper and the glue thickness of the pallet stretch film are different, so it is difficult to grasp accurately. The thickness of the 9 silk mask is also detected by coating a layer of glue on the reverse side. Up to 11 silks.
