How to handle the surface of stretch wrapping film correctly

  How to handle the surface of stretch wrapping film correctly? With the continuous emergence of various new materials, new equipment and new processes, the  stretch wrapping film  will develop towards the direction of diversification, specialization and multi-functional composite film.   The longest method for surface treatment of stretched film is corona treatment. The basic principle is: by applying high temperature between the metal electrode and the corona treatment roller (usually a high-temperature, ozone-resistant, and highly insulating silicone rubber roller). The high-frequency and high-voltage power supply generates electric discharge, which ionizes the air and forms a large amount of ozone. At the same time, high-energy electric sparks hit the surface of the film.   The magnitude of the wet tension on the surface of the corona treated stretched film is related to factors such as the voltage applied to the electrode, the distance between the electrode...

How to avoid crystal point in stretch film production?

图片
  Stretch film is a relatively thin film. It has been widely used in various digital products. There are more and more manufacturers of stretch film, and the competition among enterprises is also increasing. Different companies make stretch films. The materials are different, but it is inevitable that you will encounter some quality problems. So how to avoid the occurrence of crystal points in the production of stretched film, the following is introduced by the  stretched film  manufacturer  by Zhiteng. The appearance of crystal points is a common quality problem of stretched film materials. Crystal points refer to pits on the surface of stretched film materials, which are also called bright spots. They mainly appear on three-layer stretched film materials. The main cause is Because silica gel is used for synthesis, silica gel has fluidity. If the surface of the stretched film material encounters the extrusion of some small particles, crystal points will be formed. T...

Why does PE stretch film have glue residue?

图片
  Why does PE stretch film have glue residue? There are many types of  PE stretch films  on the market, such as mobile phones and other electronic products, and food preservation. PE stretch film is a very important protective product in the industry. It can avoid the abrasion and pollution of the product during transportation, and it plays a very important role in the industry. However, we sometimes find that there will be residual glue after the PE stretch film is used. What is the reason?   1. To check whether the high temperature resistance data of the used PE stretch film meets the production request, the temperature resistance is usually 210 degrees-260 degrees.   2. Is the temperature data of the production line within the technical request scale? Is the temperature too high? Check if the temperature sensor is normal.   3. The product's own quality problems, whether it is heated and cured strictly according to the pressure-sensitive adhesive baking d...
