Heavy-duty filament tape

3M 89812 is a clear filament tape reinforced with continuous glass yarn filaments and a synthetic rubber resin adhesive. The laminated adhesive layer and multilayer adhesive system prevent delamination while providing strong initial adhesion and long-term holding power on most fiberboard surfaces, including recycled and printed boards. It is designed for heavy-duty sealing, shipping and splicing applications.

Users needing strong box closure

This tape suits packers and shippers who require a tough, clear film that resists abrasion and moisture to keep boxes closed for long periods. It is not intended for light-duty office tasks, decorative wrapping or applications that do not need reinforced filament strength and aggressive adhesive performance.

Glass yarn filament reinforcement

The continuous glass yarn filaments embedded in the polypropylene backing give the tape its high tensile strength and resistance to splitting, making it the key specification that determines suitability for heavy-duty packaging and splicing jobs.

Questions about this item

How do I apply the 89812 tape so the glass filaments do not tear?

Unroll the tape straight onto the box, press firmly with your hand or a roller to activate the synthetic rubber adhesive, and avoid stretching the film which can pull the continuous glass yarns apart.

What part of the 89812 tape degrades first and needs checking?

The synthetic rubber resin adhesive can lose tack after prolonged heat or UV exposure, so inspect the seal on stored cartons every few months and re-tape if the bond feels weak.

At what load does the 89812 tape typically give way during a long haul?

The continuous glass yarn reinforcement holds high tensile stress, but the polypropylene backing will stretch and eventually split if the box shifts repeatedly under heavy stacked weight.
