Common Types of Adhesive Tapes

Pressure sensitive tapes
Abbreviated as PSA, this type of adhesive tape consists of a sticky tape, one sided or double sided, which is applied by light pressure. The materials used for the tape range from paper, plastics, films, textiles or cloths, metal sheets or composite materials. The tape is sticky as it is, meaning that it works without thermal application or any other related chemicals, such as solvents or acids. A release liner or other release agents are used on the backing of the tape to prevent sticking before the peeling process.

Heat activated tapes
This type of adhesive tapes is activated when a heat source is applied. They are extensively used when sealing boxes and packaging, such as cigarettes packaging. Other types of thermal tapes can be released when heated. These are used mainly in the semiconductor industry, where special care must be given to small delicate components.

Water activated adhesive tapes
Known also as gum paper tape or gum tape, this type of tape consists of sheets of Kraft paper with and added starch glue or animal glue. The tape becomes sticky and adheres to surfaces only after applying water. Tapes are available in simple layers, double layers or reinforced with fiberglass filaments. The adhesives used can be asphalt or hot melted polypropylene. Water activated adhesive tape can be used for closing boxes, envelopes or other receptacles.
