Strapping or filament tape is a pressure-sensitive material that allows for bundling applications, carton closing and sealing reinforcement package, unitizing loads, and securing products during shipment.
Filament tapes have reinforcements of tensilized polyproylne, polyester yarn or glass yarn filaments. They vary in tensile strength and adhesive types including: natural rubber, synthetic rubber, modified synthetic rubber, and clean removal.

Additional applications of filament tape beyond packaging include metal coil tabbing, residue-free temporary holding of components in an assembly (appliances), and splicing of belting

In short, they are used with larger heavier jobs where extra tape strength is needed.
