      Stretch film is the packaging material that we often use. We can know the quality of stretch film through the stretch film production process. When we need to purchase a large number of stretch film, it is necessary to visit the supplier's stretch film production process, so what is the stretch film production process? Now I will introduce it to you.



1. Lower membrane unwinding
The lower film is installed on the winding shaft, and the clamp on the chain clamps the edge of the lower film. Through the operation of the chain, the lower film is driven to move forward. In order to ensure the stability of the lower film tension during the operation, a tension adjusting device is installed at the unwinding position.


2. Upper membrane unwinding
The upper film is installed on the winding shaft, and the lower film is combined with the upper film at the heat sealing plate through the tension roller, cursor tracking device and guide roller. In order to ensure the stability of the upper film tension during the operation, the tension adjustment device is installed at the unwinding position.


3. Slitting
The whole film with products needs to be cut in two directions: horizontal and vertical, so that multiple products after packaging can be divided into a single product.


4. Stretch forming
When the semi-finished stretch film runs under the stretch forming plate, the lower film is pre heated by the heating plate, and then the stretch forming is carried out.
