Comparison Of The Thickness Of Wound Film And Stretch Film

The viscosity of the wound film with larger thickness is relatively low. The viscosity of the wound film is determined by its own characteristics. In the production process, the over-thick wound film formed by adding plasticizers has different requirements on the specific production process, and the production formula should also be changed, which will reduce the self-viscosity of the wound film and reduce its overall quality. By increasing the thickness of the winding film, the mechanical performance of the winding film is sacrificed, but the safety factor of the initial protective layer of the winding film is significantly enhanced. Thick packaging is more fully guaranteed for the safety of the product. If the winding film is thicker, the wider the width of the machine equipment, the more difficult it is for the winding film produced to reach the thickest actual thickness. This is because the winding film is a fluidic film, and in the process of fluidic film, it will become thinner and thinner. Some single winding film machine equipment, in terms of thickness control is relatively easier.
