Transparent soft PVC film is a type of plastic film that is used for a variety of applications such as packaging, insulation, and printing. It is typically made from polyvinyl chloride (PVC) resin, plasticizers, stabilizers, and other additives that give it the desired properties.

The production process for transparent soft PVC film typically involves the following steps:

1. Mixing: The first step is to mix the PVC resin with plasticizers and other additives in a high-speed mixer. The mixing process helps to distribute the additives evenly and ensure that the PVC resin is properly plasticized.

2. Extrusion: The mixed PVC compound is then extruded through a flat die to form a thin sheet of film. The thickness of the film can be controlled by adjusting the gap between the die and the cooling rollers.

3. Cooling and Calendering: The extruded film is then cooled on a series of cooling rollers to solidify the material and control its thickness. The film is then passed through a set of calender rollers to smooth out any surface irregularities and improve the transparency of the material.

4. Cutting and Packaging: The finished film is then cut into the desired length and packaged in rolls for storage and transport.

Overall, the production of transparent soft PVC film requires precise control of the mixing, extrusion, cooling, and calendering processes to ensure that the film has the desired properties. The film is transparent, soft, and flexible, making it ideal for use in a wide range of applications such as packaging, insulation, and printing. It is also resistant to chemicals, oils, and UV radiation, which makes it a durable and long-lasting material.
