1 1/4" Blue/Grey Frame Sealing Tape
Frame sealing tape seals off raw wood rabbets and fillets to protect the art and stop acid migration. This tape is acid-free, with a lignin-free buffered paper. It is laminated to a thin aluminum barrier layer and coated with an aggressive, acrylic adhesive that bonds firmly to raw wood. The aluminum provides a barrier that stops acid migration and meets the FACTS standard for maximum preservation framing.
