Premium high-performance packaging tape with polypropylene backing and synthetic rubber adhesive for heavy-duty box sealing, offering superior tear resistance and conformability under stress.
Scotch® Box Sealing Tape 373 is a premium high-performance packaging tape engineered for heavy-duty applications across a wide range of materials and surfaces. This professional-grade tape features a 2.5 mil (64 micron) biaxially oriented polypropylene film backing combined with a synthetic rubber adhesive that delivers exceptional holding power and tensile strength. The tape is specifically designed for flexibility and conformability under stress, making it ideal for ecommerce, single parcel shipments, and demanding packaging environments where boxes may be over or under-packed.
The polypropylene backing provides superior edge tear and split resistance while resisting abrasion, moisture, chemicals, and scuffing for long-lasting performance. This tape adheres instantly and consistently to most surfaces, including cartons with high levels of recycled content, and meets FDA guidelines for indirect food contact. With an elongation at break of 160% and tensile strength of 30 lb/in (525 N/100mm), the tape ensures secure containment for packages weighing up to 100 lbs. The easy unwind and smooth dispensing characteristics make it compatible with both manual dispensers and 3M-Matic™ Case Sealers for efficient high-speed automated packaging lines.
Scotch® Box Sealing Tape 373 is recommended for heavy-duty packaging applications including recycled liner paper, fiberboard, and regular slotted containers (RSC). It is particularly popular in electronics, ecommerce, high-value goods, and general manufacturing industries where reliability and consistency are critical. Each case contains 36 rolls of 100-meter tape, providing comprehensive coverage for large-volume shipping and distribution operations.
