Scotch 355 Box Sealing Tape is an industrial-grade packing tape that provides durable performance in demanding packaging environments. The backing is made of polyester – our strongest backing material – and is resistant to abrasion, moisture and scuffing. This high-performance ultra-adhesive packaging tape securely closes double and triple walled corrugated cartons, including those with high recycled content, saving time and reducing closure failures. The tape's conformable backing resists score line breaking and center seam splitting, making it ideal for heavy-duty box and carton sealing operations, including for heavy-weight packages and overseas/export packing and shipping.
