What is the process of EVA Film Extrusion Line?

An EVA (Ethylene-Vinyl Acetate) film extrusion line is a complete set of industrial machinery designed to transform raw EVA copolymer pellets into a thin, continuous, and uniform film. This film is prized for its excellent clarity, flexibility, softness, toughness, and strong sealing properties. EVA films are widely applied in solar panel encapsulation, laminated glass, packaging, and decorative materials.

Laiyi film extrusion laminating line PERFORMANCE,ADVANTAGES:

• This line adopts vertical oven to ensure the drying performance and save the equipment space.
  
  

• Double station turret shaftless unwinder and rewinder ensures the stability of auto-splicing without reducing line speed.

EVA Film Extrusion Line Extrusion Process:

EVA resin is melted in an extruder.

The molten EVA is extruded through a T-die (flat film extrusion) or a circular die (blown film extrusion).

Film is cooled, stretched, and wound.

Temperature Control: Precise heating/cooling system to prevent premature crosslinking of EVA.

EVA Film Extrusion Line Components:

Extruder (usually single-screw or twin-screw)

Laminator

PLC Operation Cabinet

Chill roll unit or air ring or three rollers chilling (for cooling)

Corona treatment system (to improve adhesion)

Thickness control system

Automatic winding system(Friction Rewinder)

Would you like me to prepare a professional product description of an EVA film extrusion line (like a brochure/website text), or a technical process overview (for engineers)?
