How to grasp the viscosity of the wrapping film

There are many materials for the manufacture of wrapping film, which mainly depends on the application field of the product, so if you want to control the viscosity of the coiled film, you can work hard on the material. Not all coiled films can be matched with C4-LLDPE, and C6 and C8 materials are often used because of their simple processing.

The temperature will also affect the viscosity of the coiled film. Generally, we will put the product in an environment of 15 to 25 degrees. If the temperature exceeds 30 degrees, the viscosity will increase; if it is lower than 15 degrees, the viscosity will increase. , the viscosity will deteriorate again. Because of the polyethylene component in the coiled film, we can adjust the amount of polyethylene in the adhesive layer to achieve the desired viscosity.

Coiled film is mainly mixed and extruded by several different trademarks of polyolefin resin, which has puncture resistance and high degree of resistance. In foreign trade export, papermaking, hardware, plastic chemical, building materials, food and pharmaceutical industries.
