Characteristic Of Stretch Film Thickness Of Wound Film

When the thickness of the winding film itself is relatively large, it is more difficult to apply, especially the hand winding film, which will reduce the working efficiency of the winding film.
The thickness of the wound film is larger, the viscosity is relatively low. The viscosity of the wrap film is determined by its own characteristics, and in the production, by adding plasticizers to form, too thick wrap film, in the specific production process has different requirements, and in the production formula is also to change, which will reduce the self-viscosity of the wrap film, but also reduce its overall quality. By increasing the thickness of the wrap film, the mechanical performance of the wrap film is sacrificed, but the safety factor of the initial protective layer of the wrap film is significantly enhanced, and the thick packaging is fully guaranteed for the safety of the product. The thicker the wrap film is, the wider the width of the machine equipment, the more difficult it is to produce the wrap film to reach the thickest actual thickness, because the wrap film is a casting film, and in the casting process, it will become thinner. Some single winding film machine equipment, in terms of thickness control is relatively easier.
