Apr 12, 2018

The stretch film wrap adopts imported resin and advanced flow-yielding film extrusion production process. The stretch film has the characteristics of good tensile properties, tear resistance, strong penetrability, high transparency, good self-adhesion, high shrinkage, tight packaging, and no looseness. Stretch film is widely used in chemical raw materials, fertilizers, food, mechanical and electrical products, light textile products such as single or tray packaging and other strapping packaging.

Step one,

The lower film is mounted on the take-up reel, the clip on the chain clamps the edge of the film, and the running of the chain drives the film to run forward. In order to ensure the smoothness of the tension of the film during operation, the film is installed at the unwinding position. Tension adjustment device.

Step two,
The upper film is mounted on a take-up reel and is heat-sealed with a lower film at a heat-sealing plate through a tension roller, a cursor tracking device and a guide roller. In order to ensure the smoothness of the tension of the upper film during operation, the film is placed at the unwinding site. A tension adjustment device is installed.
Step three,

The entire film with the product needs to be slit in both horizontal and vertical directions so that multiple products after packaging can be cut into individual products.
Step four
When the semi-finished stretched film runs under the stretched forming plate, the lower film is pre-heated by a hot plate and then stretch-molded.
