Foil Backed 3.5" Frame Sealing Tape

Lineco's 3.5"  Foil Backed Frame Sealing Tape seals off raw wood rabbets and fillets to protect the art and seals filler boards to the frame. 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.
