zhiteng stretch film

  With the wide application of   PE stretch film   in the logistics industry, PE stretch film is a popular packaging material nowadays. The stickiness of PE stretch film, if the stickiness of PE stretch film is good, the packaged products will be stronger and stronger, reducing damage caused by external factors. So what factors will affect the viscosity of the PE stretch film?   The factors that affect the viscosity of the PE stretch film are as follows: 1. Whether the self-adhesiveness is good;   2. How to obtain the viscosity of the PE stretch film itself;   3. The temperature of the cooling roll.   There are many materials for the production of PE stretch film, which mainly depend on the application field of the product. Therefore, if you want to control the viscosity of the PE stretch film, you can work hard on the material. Not all C4-LLDPE can be matched with PE stretch film. C6 and C8 materials are often used because of their ease of processing,...

  How to do if the stretch film tension is not uniform? The  stretch film  is dust-proof and moisture-proof, effectively protecting the goods while packaging the goods. It is an environmentally friendly packaging material. We will encounter uneven tension of the stretch film during use. Today, I will introduce how to solve the uneven tension of the stretch film.   Stretch film tension and equipment display tension have different meanings. Therefore, different equipment display tensions should be set for different types and thicknesses of stretch films. The surface tension of the stretched film depends on the free energy of the plastic film, and the surface energy of the stretched film depends on the film's molecular structure.   One: Non-polar polymer, surface free energy is negligible. The wet surface tension is low, the after-sales service of the Haier washing machine is generally about 30 dyne/cm. Theoretically, if the surface tension of the object is less th...
