pressure-sensitive tape

Strips of paper, plastic, etc., opaque or transparent, coated or impregnated on one or both sides (usually the former except for use in encapsulation) with a pressure-sensitive adhesive. In the form of cellophane tape, which is a clear plastic that is glossy on one side and coated with adhesive on the other, it is sometimes used in the repair of torn leaves, documents, etc., and for encapsulating archival papers. In the usual case it darkens with age, is difficult to remove, removes the print when it is detached, and stains the paper to which it adheres. The acetate tape, or transparent mending tape, which has a matte surface and appears colorless when in the roll, has a much higher degree of permanence and does not change color; however, it, too can be damaging to archival materials. Masking tape is strong brown paper tape of crinkly texture, made in rolls of various widths. Its pressure-sensitive adhesive secures the tape firmly to any hard, dry, non-fibrous surface, and it is easily peeled away. It is used to mask areas that are not to be treated. Masking tape generally becomes difficult to remove if left in place for more than a few days or if exposed to high temperature. Benzene or ether, both of which are toxic (especially the former), flammable, and therefore dangerous to use, are solvents capable of removing pressure-sensitive tapes. (233 , 309 )
