Sunpro Group has an upper hand in the stipulation of light gauge conversion foils. Foil material, temper, surface, winding, thickness, thickness tolerance, pinhole count, wettability, stickness, splicing etc are taken into consideration when the production of Light Gauge Conversion Foil is carried out. Not only during the production time but during the testing time certificates are being issued regarding the thickness and width of the foil. We even produce the Light gauge conversion foils as per the clients requirements. As per the price is concerned we provide Foils at a very minimal price to our clients.

Sunpro Group manufactures light gauge converter foil with the following general specification. The final product specifications made as per agreed contract with the customers.

Foil Material

Aluminium alloy AA-1200 or AA 1235 conforming to Aluminium Association.Specification.

Thickness

0.007 mm, 0.008mm, 0.009 mm and 0.012 mm

Thickness Tolerance

± 8% over nominal thickness.

PINHOLE COUNT

FOIL THICKNESS (MM)	AVERAGE PINHOLES (PER SQ. M)	MAXIMUM
