Scotch® High Tack Box Sealing Tape 375+ is a high-performance packing tape that securely closes a variety of heavy weight box materials, including recycled fiberboard. The strong adhesive securely seals packages to help prevent tampering and tape failure during moving, shipping and delivery. The polypropylene film backing is easy to unwind and resists abrasion, moisture, scuffing and edge tear.

Created for Superior Strength in the Toughest Commutes

The supply chain journey is subject to challenges at every step: hard-to-seal boxes, line slowdowns, tampering, and open package returns. Scotch® High Tack Box Sealing Tape 375+ was created as part of the 3M total system solution to help solve these problems, so you can be confident your packages will stay securely sealed all the way to their destination.

The hot melt adhesives instantly bonds to the box, helping prevent tampering and tape failure – even during extreme shipping and delivery conditions. It features a high tack and instant stick, allowing you to either apply by hand, semi-automatic or virtually jam-free with our 3M-Matic Case Sealers.

Durable and Dependable

Packing and packaging tapes are designed to securely close regular slotted containers (RSC) and packages used for moving, shipping and distribution. These tapes feature durability and high strength and work especially well on challenging recycled corrugate and fiberboard. Because it is consistent and reliable, heavy duty sealing tape is popular for electronics, ecommerce, high value goods and general manufacturing packaging applications.
