Product Description

The 3M 7000142907 is a heavy duty flat stock paper tape designed for surface protection during processing and transit. Known as the 3M Heavy Duty Protective Tape 346, it features a natural tan paper backing at 16.7 mil total thickness with a rubber-based adhesive that bonds firmly to metals, plastics, and a wide range of other materials. At 12 inches wide and 60 yards long per roll, this tape delivers broad coverage for masking and protecting large surface areas. It is suited for both indoor and outdoor applications, making it a versatile option for fabricators, contractors, and trade professionals managing parts or finished goods in transit or in-process.

This tape is commonly used in manufacturing, construction, and trade settings where temporary surface protection is needed. It guards metals and plastics against scratches, scuffs, and contamination during handling, fabrication, or shipping. The wide 12-inch format makes it practical for wrapping large panels, sheet metal, pipe, extruded profiles, and similar workpieces. It performs in both indoor staging environments and outdoor transit conditions.
