What Is Adhesive Tape ?

Adhesive tapes is a combination of a material and an adhesive film and used to bond or join objects together instead of using fasteners, screws, or welding. Applying adhesive tapes in lieu of mechanical fasteners enables you to use lower temperature applications, which can simplify the manufacturing processes. Additionally, adhesive tapes can protect your surface area since there is no need to damage the surface by using fasteners or screws. Adhesive tapes are great solutions for automated product production, whereas liquid adhesives are messy and time-consuming because they need to be sprayed or rolled onto the surface before bonding takes place.

What Are Adhesive Tapes Made Of ?

Adhesive tapes consist of a material called a backing or carrier (paper, plastic film, cloth, foam, foil, etc.), which is coated with an adhesive and a release liner if needed. The adhesive-coated backing or carrier is then wound up to form a long jumbo roll of tape. The jumbo roll is then slit into narrow width bands to produce several rolls of tape. Each roll and its composition are unique and can be tailored to specific applications for a wide variety of bonding solutions.

How Are Adhesive Tapes Applied ?

Adhesive tapes can be pressure sensitive, thermally activated or may even require moisture to work. Others, such as latex gums, adhere to themselves.

Most Popular Types Of Adhesive Tapes:

• Pressure sensitive adhesives (PSAs) are tacky at room temperature in dry form. They adhere firmly to a variety of surfaces and require only the application of a finger or hand. PSAs do not require water, solvent or heat activation in order to bond to materials such as paper, plastic, glass, wood, cement and metal. The recommended bonding pressure is 14.5 – 29 psi =^ 10 – 20 N/cm². The temperature during application should be moderate, somewhere between 59º F and 95º F. Lower temperatures might lead to insufficient “wetting” or “coverage” of the adhesive on the substrate. Very high temperatures may cause the tape to stretch when being applied, which could create additional stress in the final application.
• Heat activated tape is usually tack-free until it is activated by a heat source. Heat activated tape requires time at elevated temperatures at 180˚F or higher to achieve a bond.  Heat-activated adhesive allows for aggressive bonding to difficult surfaces such as rubber, EPDM, PU and PVC-based plastic materials. It can be made with different carriers that are suitable for a variety of applications.
• Water activated tape, gummed paper tape or gummed tape is a starch or an animal glue-based adhesive on a kraft paper backing which becomes sticky when moistened. Water activated tape is inexpensive and is used for closing and sealing boxes.
• Non-adhesive tapes, films or laminates do not have an applied adhesive because they are self-adhering. PTFE thread-sealing tape is a type of non-adhesive tape.
