371+ Clear Carton Sealing Tape

This 3M Scotch 371+ tape is a clear polypropylene carton sealing tape designed for machine application. Each roll measures 2 inches wide by 1,000 yards long and carries a 2.1 mil thickness. The hot melt synthetic rubber adhesive delivers a tensile strength of 22 lb per inch. A six-pack supplies enough length for high-volume packing lines.

Light-duty sealing for uniform cartons

The tape suits operations that run case sealers on lightweight, uniform boxes where a 35 °F minimum service temperature is acceptable. Buyers who need heavy-duty holding power, cold-storage performance below 35 °F, or hand-tear convenience should look at other formulations. The light-duty strength rating means it is not intended for over-packed or high-stress shipments.

22 lb/in tensile strength decides fit

The single specification that determines suitability is the 22 lb per inch tensile strength combined with a 42 oz per inch adhesive strength. If your cartons regularly exceed the holding capacity implied by these figures, the tape will not provide a reliable seal. Match the strength rating to your typical box weight before ordering.

Questions about this item

Which 371+ roll size should I pick for general box sealing?

Each roll is 2 in wide by 1,000 yd long and the pack contains six rolls, giving plenty of length for high-volume shipping.

What does the 22 lb/in tensile strength mean when I tape a carton?

The backing resists 22 lb of force per inch of width before breaking, so a standard seal holds firm under typical shipping loads.

How does the 2.1 mil thickness affect machine dispensing?

At 2.1 mil the tape feeds smoothly through most automatic case sealers while still providing a secure bond on lightweight boxes.
