Optical composite film sheet extrusion line helps optical film to be unique

Optical composite film sheet extrusion line helps optical film to be unique

From display devices such as TVs to electronic products such as tablets and mobile phones, more and more industries have an increasing demand for optical films. PC/PMMA composite sheet, an optical film, can achieve excellent glass-like effect through advanced surface treatment technology. This material is gradually being used in the mobile phone back cover market. Having more perfect optical quality and higher flatness is a major guarantee for the glass-like effect of the composite sheet, and it is the basis for this material to go longer and farther on the road of mobile phone back cover.

Why GWELL’s EVA/POE film extrusion Line is more popular? Are there any advanced technologies?

Why GWELL’s EVA/POE film extrusion Line is more popular? Are there any advanced technologies?

Gwell EVA film extrusion line utilizes EVA resins (having 30 to 33% VA content) as base material to produce EVA films for solar photovoltaic cells. In addition, this line can make hot melt adhesive EVA interlayer film by changing the formula and process. Another kind of film is EVA/POE/EVA-EPE, this type of film is made by co-extrusion line.
