USAGE
This machine is vertical PVC heat shrink film blowing machine.
PVC heat shrink film made by this machine has good transparency, gloss and high shrinkage, etc., it is popular packaging material, widely used as printing label for water bottle, shampoo bottle etc, and the outer packages of food, beverages, tea, glass products, handicrafts, sanitary wares, cosmetics, electronic products, and so on.
FEATURE
1.The screw is made of high-quality steel 38GrMoAIA, precisely formed by heat treatment, it has the features of high yield, good plasticization effect, and long operating life.
- Temperature is controlled electronically and automatically.
VVVF drive motor enabled the drive smooth and control flexible.
The adoption of four times traction made it possible to suit a wide range of the width of the blown film and improve yields.
Using new screw diameter ratio: 23:1, which is more suitable for high melt viscosity, thermal stability, raw materials plastination. - The second time blowing can adopt water heating tank, it can make the film more transparent and lustrous. Which is more better for printing and making label.
