Macro introduces PV sheet line

Macro's PV sheet line, which produces the encapsulant material used in the assembly of solar modules, features its patent-pending low shrink extrusion technology that minimises shrinkage in the final sheet to below 2%, which Macro claims is the lowest on the market. The reduced shrink properties leads to significantly greater yields as less material goes to waste during solar module manufacture.

The line produces encapsulation sheet made of a variety of materials including EVA, PE, PVB, and TPU; however, the technology can also be applied to other applications where low shrinkage is required, such as rigid sheet and lamination films or sheet where shrinkage creates issues with quality.

Macro claims the line is optimised for simplicity by creating sheet without the use of a carrier web and incorporating a two-sided embossing option that allows the sheet to be wound without the need of an interleave web. The line is completed by fully automatic winding technology with zero waste, straight-edge cutovers that creates jumbo rolls up to 1 m in diameter.
