Xindacheng EVA solar film production equipment is designed for manufacturing EVA encapsulant film used in photovoltaic (PV) module encapsulation.
The equipment integrates material feeding, extrusion, film forming, cooling, thickness control and automatic winding to provide stable and continuous EVA solar film production. The configuration can be adjusted according to film width, thickness, output and production requirements.
EVA Solar Film Production Process
The EVA solar film production process includes raw material feeding, extrusion, film forming, cooling, thickness control and winding.
EVA material is accurately fed into the extruder, where it is melted and plasticized under controlled processing conditions. The molten material is then formed into a continuous film through the T-die.
After film forming, the film passes through the cooling and thickness control sections to maintain dimensional consistency. The finished EVA solar encapsulant film is then wound into rolls for further use in photovoltaic module manufacturing.

What Is EVA Solar Film?
EVA solar film, also known as EVA solar encapsulant film, is a polymer film used in photovoltaic module encapsulation. During PV module manufacturing, the film is laminated with solar cells and other module layers to provide adhesion and protection.
The quality of EVA encapsulant film is affected by material formulation, extrusion stability, film thickness uniformity and production process control.
Why Choose EVA Film Extrusion Equipment?
For manufacturers planning to produce EVA solar encapsulant film, the extrusion system needs to provide stable material processing, consistent film forming and reliable winding.
Our EVA film extrusion equipment combines these processes into a continuous production system and can be configured according to the required production capacity and film specifications.
