GF 401 is a 3.0 mil lustre clear UV pressure sensitive vinyl laminate that offers resistance to ultraviolet degradation with a permanent acrylic adhesive on a smooth 53# liner. This calendared PVC laminate also protects graphics from abrasion and moisture. GF 401 is best applied by the cold laminating process without the addition of heat and is designed to protect digital and screen printed images for exhibit and display graphics. GF 401 can be used in most instances where an overlay with a lustre finish is required on interior or exterior applications.
