As for PVC film preservation units, we usually see two types: casting production line and blowing film production line. We will provide a detailed introduction to these two different units in the following content.

PVC cling film (casting) production line

This type of production line uses PVC resin powder as the main raw material, mixed with various brands of auxiliary materials, thoroughly stirred, and extruded through an extruder to produce self-adhesive PVC cling film. This film has high tensile strength, good droplet performance, high transparency, and good surface gloss performance. The packaged product is both aesthetically pleasing and can maintain the freshness of the food for a long time. Therefore, the PVC cling film produced through this production line can be widely used for packaging and preservation of refrigerated products such as vegetables, cold dishes, fruits, raw meat, etc. in supermarkets, hotels, restaurants, bakeries, and households.

PVC cling film (blow film) production line

This production line uses blow molding method to produce PVC cling film, which has the following characteristics: 1 Thin diaphragm: The lower limit can reach 0.006mm. 2. The roll diameter is large, with each roll ranging from 6000m-9000m, suitable for machine packaging and packaging of small rolls. 3. High yield.
