Type 691 is made of a polyethylen-coated cloth tape. It is waterproof, sticks well on rough and irregular surfaces and it is easy to tear by hand. The tape has a good adhesion. The Gaffer Tape has a matt surface - so it is the solution for application problems whenever a non glossy and non refl ective surface is of importance. You can remove it without any residue of many surfaces up to 14 days.
It is used especially for on stage and back stage jobs in the theatre, opera etc. It is also used for temporarily fixing of cables on carpets etc. and for marking floors.
