Factors Affecting Stretch Film Viscosity

Stretch film itself has a certain viscosity, which has a profound relationship with its own raw materials. As a relatively common packaging product in the logistics industry, if its viscosity is high, the packaging of the product will be improved. It is more firm, but once the viscosity is reduced, the protective function will be greatly reduced, so it will cause certain damage. Therefore, in order to reduce the occurrence of this situation, we need to find the factors that affect its viscosity and avoid it in time. Specifically, we briefly introduce it below.

(1) There are many materials for making stretch film, which mainly depends on the application field of the product, so if you want to control its viscosity, you can work hard on the material. It is not suitable for all C4-LLDPE materials. C6 and C8 materials are often used because they are easy to process, and the temperature will also affect its viscosity. Generally, we will place the product at a temperature of fifteen to twenty-five degrees. In the environment, if the temperature exceeds 30 degrees, the viscosity will increase; if it is lower than 15 degrees, the viscosity will deteriorate again.

(2) Since there are polyethylene components in the stretched film, we can adjust the amount of polyethylene in the adhesive layer to achieve the required viscosity; because the molecular weight distribution of the stretched film is relatively narrow and the processing range is relatively narrow, so Usually only five percent of polyethylene can be added to reduce the melt viscosity, so that its flatness will also be improved to increase the flatness of the film.

So everyone should understand that the viscosity of the stretch film is one of the important factors in determining the quality of the product. If the product loses its protective effect, what is the significance of the existence of this product? Since it is meaningless, it will not have any effect and effect when using it.
