Polyken 824 Shrink Wrap Tape is also known as hull preservation tape and is used for taping edges of shrink wrap to a boat's hull. Also used by auto salvage and reclamation yards. It has a polyethylene film and rubber based adhesive. UV protected for prolonged expose to sunlight. Polyken 824's specially-designed adhesive eliminates residue even after extended periods of exposure. It is also conformable so it adheres to rough surfaces and is also easy to unwind. Shrink Wrap Tape is used to seam shrink wrap film sheeting together; patch holes in shrink wrap; secure waste disposal bags; and to hold doors in place. It is also used for stucco & plaster masking and other outdoor masking applications where UV resistance is required. Our distributor gets this made specially from Berry Plastics in white with serrated/pinked edges for easy tearing - no cutting is needed.
