This is the technical term for any type of "adhesive tape" or "sticky tape". It means that the adhesive, at room temperature, is aggressive and permanently tacky and will adhere to a wide variety of surfaces without the need for more than finger or hand pressure. Tapes can either have adhesive coated one side of a carrier (single sided tapes) or on both sides (double sided tapes). The vast majority of adhesive tapes sold fall under this category, although there are also tapes that are dry or non-tacky to the touch at room temperature and require an activator to get them to bond such as heat, water or some other solvent.
