Adhesive tape is one of the most used handy tools that is used for both indoor and outdoor purposes. From home to the office, this is a must-have tool. Tape repair cracks seal leakage and hang things. Tapes vary for intended purposes. Different types of tapes are available on the basis of uses. Tapes can be pressure sensitive, heat or water activated. There are varieties of tapes namely duct tape, gaffer’s tape, electrical tape, mounting tape, painter’s tape etc.
What is a Tape?
A tape is a tool used widely for sealing, repairing, binding, hanging etc. made of a strip of substrate material coated with adhesive on one side or on both sides.
Basic Design of tapes:
Adhesive tapes design varies on manufactures but three components carrier, release liner and adhesive are basic parts of all tapes.
Carrier or backing
Carrier or backing of a tape is a way to support and separate adhesive coatings. It provides additional stability and strength for handling at the time of assembling tape with the substrate. Carrier or backing also assists secondary operations like die cutting or slitting. Materials for Backing of tapes include Foam, Paper, Tissue, Polyester, Cloth, Polyethylene, etc. It can be different from the base of using purpose. The cloth is used as a carrier for duct tape where PVC is the backing material for electrical tape.
This component of tape is a protective covering which usually separates the adhesive from the backing and another adhesive for double-sided tape. It also facilitates unwind and protect adhesive before final assembly. Materials Suitable for liners are Densified Kraft, Polycoated Kraft, Plastic films, or Board.
The adhesive is the substance coated with a backing material that makes possible holding two or more objects together by intimating surface contact. Adhesive can be many different types. Three main types of adhesives, RUBBER, ACRYLIC, and SILICONE are widely used for manufacturing adhesive tapes.
Types of Adhesive
What type of adhesives are used for manufacturing tapes: Different adhesives are used to make adhesive tapes. They are responsible for tape stickiness on various surfaces. Here are some adhesives as follows :
This adhesive provides tapes with an excellent weather resistance. It facilitates a faster setting time than another form of adhesives.
It provides higher strength with lower shrinkage during curing. It is well known for its toughness. It is chemically resistant and protective against environmental damage.
This adhesive makes highly flexible bonds. and are usually based on butadiene-styrene, butyl, polyisobutylene or nitrile compounds.
Silicone adhesive provides a high degree of flexibility. It can also withstand at very high temperatures.
Polyurethane and Isocyanate adhesives
These adhesives are durable and provide well enough flexibility and impact resistance.
Formates of PSA Tape
Tapes are manufactured in different types of formats based on the coating of adhesive (one sided or double sided tape) and design. Formats of adhesive tape are described as follows :
Single or one side coated PSA tape
These tapes are designed by coating the adhesive on one side of a flexible carrier. Release liners are often used to protect the adhesive of this tape. These tapes are useful when only one substrate is to be bonded and for wet laminating.
Double Coated PSA Tape
Carrier of these PSA tapes is coated on both sides and protected by a release liner. These tapes are capable of binding the same or different substrate on each side of the carrier.
Unsupported or Transfer
These adhesive transfer adhesive tapes are made without a carrier. Adhesive holds itself by its own internal strength. These tapes are used for flexibility and stretch and for bonding to irregular surfaces.
Types of Tapes Based on Activation System
On the base of activation system tapes are classified as follows.
Pressure-sensitive tape or PSA tape will stick with the application of pressure without any solvent like water or heat. These tapes are made with The tape consists of a pressure-sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil. Some have a. This adhesive tape is also known as self-stick tape, sticky tape, or just tape. It has a wide range of applications in home, office, industry, and institutions.
To activate Water activated tape warm water or solvent is necessary. The adhesive used on these tapes is usually starch- or sometimes animal glue-based adhesive. It is also known as gummed paper tape or gummed tape. These tapes are used for closing and sealing boxes. The tape is wetted or remoistened with activating water before closing boxes.
Heat sensitive tape
Heat activated tape remains tack-free until activating it by heating it up to certain temperatures. These tapes are used for packaging like using it on cigarette packs. It is often used in the semiconductor industry.
Different Types of Tape
Tapes are of many variants in term of their property and application. Here are the most popular tapes as follows:
The waterproof tape has the unique property of sticking on the wet surface as well as preventing water along with resisting moisture. It is a regular tape that everyone needs to keep in his toolbox. It is a handy tool for patching any holes or cracks in boat or pool, for sealing leaky pipes and very useful as first aid kit and medical purposes like knee pain or avoiding blistering etc. They are made of strong adhesives like rubber or vinyl and has a waterproof backing. These tapes are often used for protecting the surface from unwanted blistering or crack. You can also use different colored waterproof tapes for quick marking and leveling items.
Duct tape is the easy and instant solution for sealing, repairing any cracks or patching any holes. This versatile tool is useful for more than hundred applications from indoor to outdoor. It is pressure sensitive tape with durable adhesive along with tough but flexible backing. This tape is something that can fix anything.
Gaffer’s tape is the ultimate tool when it comes for a tough tape that leaves no residue. It is popularly known for its wide range of applications in media and entertainment industry. Filming, Photography, Entertainment or Music Industry all of them need gaffer tape. These tapes are used for multiple applications like holding cables or wrapping around wires etc.
Packing tape is well known for packaging and shipping products. Shipping and storing boxes require a different type of packing tape. Thickness, adhesive, and backing of packing tape vary on the basis of applications. Usually, these tapes are used as a closure for boxes. Opaque packing tapes are also good for covering writings or logos on surfaces. Specifically on boxes
Painter’s tape is a tool of choice for all professional and dye painter’s. The best painter’s tape gives clean and perfect paint line without peeling off the surface. These tapes are different from other masking tapes specially designed only for painting. This tape to stick to various surfaces such as drywall painted wall, floor etc.
Carpet tape is designed with unique strength and holding power that keeps your carpets, rugs or mats in place. It binds the raw edges of a carpet fragment and joins two or more sections of carpeting to create a single piece.
Mounting tape is the best alternative to screws and nails. These tapes are specially manufactured to attach items to virtually on wall, wood, metal and any smooth or delicate surfaces.
Double sided tape
The double-sided tapes are designed with a thin adhesive layer to each side of a carrier substrate material. It is also known as double-coated tape or double-faced tape. These tapes are used widely for splicing and packaging.
Electrical tape is well known for insulation properties against conductivity of electricity. Most of the electrical tapes are made of fiberglass cloth backing or many plastics. But vinyl electrical tape offers long-lasting and effective installation. These tapes are used to insulate electrical wires.
Drywall tapes are uniquely designed for drywall installation. It facilitates to make joints between drywall sheets. Backing materials of this type are usually made with cloth, paper or mesh coated with gum or pressure-sensitive adhesive. Paper drywall tapes important at typically are the weakest areas like butt joints in a drywall installation. Mesh tapes are a faster fix for the joints where strength is not as much of a concern.
Why Use Adhesive Tapes?
The adhesive has many advantages over other assembly methods like using glues, mechanical fixings etc. Here are some advantages
- Easy applying method with larger stress bearing area.
- Makes bonding between dissimilar substrates.
- Better stress distribution with a higher strength to weight ratio.
- A safer method to use with clean applications.
- Inexpensive with minimal waste of tool.
- Uniform distribution of adhesive to make bonding between substrates.
How to Use a Tape?
How to Apply Pressure – Sensitive Adhesive Tape:
Some general instructions are as follows to apply a pressure-sensitive adhesive tape:
- At first, clean and dry the surface to apply the tape. If any cleaning spray or other product is used to clean the surface, make sure no residue of the cleanser left on the surface.
- The next step is to unwind the tape carefully from the roll and then remove the release liner of the tape, it has any but not to contaminate with a finger.
- Bond the tape as soon as possible to the surface without gapping and entrapping air between them.
- Apply some pressure on the tape while bonding to surface to achieve maximum bond strength.
How to Store Tape Roll
Here are some tips to store tape roll. Storing in a good way is necessary to avoid drying adhesive of the tape.
- At first, store tape away from the light as UV light can penetrate the packaging with time.
- Store the tape in a cooler place like 60°F/15°C. The cooler is better for storing tape rolls.
- Store the tape roll in a dry place so that moisture doesn’t spoil adhesive on the tape by chemical reaction.
- Stock tape rolls on a sale rack at a safe height.
Storing tape rolls in the best way will increase the lifespan of your tape rolls. With cool, dark, and dry storage with proper stacking best tape storage, you can make the best value out of your tapes.
Which Materials Are Used For The Backing Or Carrier?
Adhesive tapes often vary in terms of backing material. Here are some common backing materials as follows :
- Paper: Paper tapes have a paper backing coated with adhesive. These tapes are also known as flat back tape.
- Cloth: The cloth is also used as a backing material for adhesive tape such as duct tape has cloth backing. To provide extra strength and heat resistance, cloth backing is reinforced with a woven cloth or a fabric layer.
- Metal Foil: Metal foils like Aluminum foil, aluminum-reinforced, and lead foils are used as backings for tapes. These backings provide flame and higher temperature resistance and high humidity. To provide more strength, metal foils are often laminated to paper or plastic films. For, PCB manufacturing Copper foil is used as backing.
- Felt: To prevent scratching Felt or non-woven backing tapes are used.
- Foam: Foams are used as backing coated with adhesive and protected by a liner. Foam backing tapes are useful for sealing, mounting, and weather-stripping.
How to Get a Strong Bond with Pressure Sensitive Adhesive
To achieve maximum bonding to substrate from Pressure sensitive adhesive tape, you need to provide the required amount of pressure. You must apply the tape on a clean and dry surface. Because it and derbies will not allow full bonding between the surface and tape. 72 hours is the optimum time for most adhesives. You must be concerned with a surface energy of the material as it allows adhesive flow or wet-out. Materials with high surface energy allow the adhesive to flow where lower surface energy materials don’t allow it.
