Adhesive tape is a tape that is coated with adhesive and used to stick objects together.
Adhesive tape that will stick with application of pressure only (i.e. without activation by water, solvent or heat) is known as pressure sensitive tape. It can consist of a wide variety of tape backings and pressure sensitive adhesives.
Single-sided tapes allow joining of two overlapping or adjoining materials, while double-sided tape (adhesive on both sides) allows joining of two items back-to-back.
