What Is A Glass Filament Tape?

A glass filament tape or otherwise also known as a strapping tape is a pressure-sensitive tape that is used for several packaging functions such as closing corrugated fiberboard boxes, reinforcing packages, bundling items, pallet unitizing, etc. It is made of a backing material coated with a pressure-sensitive adhesive. The backing material commonly used is usually a polypropylene or polyester film with some fiberglass filaments, fiberglass strands or polyester filaments embedded into it to add high tensile strength. Kindly note that filament tapes with fiberglass filaments will always be stronger than those with polyester filaments. Invented by by Cyrus W. Bemmels, a scientist working for Johnson and Johnson in 1946, filament tape are strong tapes with some grades having as much as 600 pounds of tensile strength per inch width.
