Scotch® Box Sealing Tape 355, one of the very best performers in the Scotch® polyester line of tapes, securely closes double and triple walled corrugated cartons, including those with high recycled content, saving time and reducing closure failures. The polyester backing resists moisture, abrasion and scuffing to hold strong throughout the shipping process.To ensure Scotch Box Sealing Tape 355 would stand up to demanding packaging applications, design engineers combined a thick biaxially oriented polyester backing with a hot melt synthetic rubber resin adhesive to create a tape with high adhesion, tensile strength, and elongation at break. It complies with environmental considerations of ASTM D1974-92 and meets CID A-A-1684B and ASTM D5486 Type III. This tape is water-resistant per ASTM D5570.
