Masking tape, also known as painter's tape, is a type of pressure-sensitive tape made of a thin and easy-to-tear paper, and an easily released pressure-sensitive adhesive. It is available in a variety of widths. It is used mainly in painting, to mask off areas that should not be painted.
Some inexpensive masking tapes are suited for general use in homes and offices. Others are designed for professional house painters. Masking tapes for automotive or aircraft use have special characteristics for these demanding applications.
