White Frame Sealing Tape - Foil Back - Self Adhesive 1 1/4 x 85 ft

Frame sealing tape seals off raw wood rabbets and fillets to protect the art and stop acid migration. An acid-free, lignin-free buffered paper is laminated to a thin aluminum barrier layer and coated with an aggressive, acrylic adhesive. The aluminum provides a barrier that stops acid migration and meets the FACTS standard for maximum preservation framing.
