Why the different backings / carriers for the adhesive?
The backing material on which the adhesive is applied to depends heavily on where or how the tape will be used. Common masking tape uses paper as it is economical and the application is typically temporary. CLOTH or DUCT Tapes, as they are known as, are widely used for joining and sealing but typically at low temperatures and in dry conditions. Tapes made of polyester or other plastic films have more stretch, higher temperature ratings and may be used in harsher environments or conditions.
