from the Blog Single Sided Vs. Double Sided Tape


At BDK, we provide a wide range of high quality adhesive tapes.

With so many different varieties, we thought we would outline some of the differences between single sided and double sided tape to help you decide which would better suit you and your application.

Single Sided Tape

What Is Single Sided Tape?

Single sided tapes only have an adhesive coating on one side. Usually, the backing is treated with a release coating so the adhesive bonds to the correct side of the backing.

What Kinds Of Single Sided Tape Are There?

There are many different varieties of single sided tapes that are suited to different types of domestic and industrial applications, some include:

  • Electrical Tapes – Conductive qualities used for electrical components
  • Masking Tapes – Used for general and industrial masking requirements
  • Foam Tapes – Used for gap filling requirements
  • Foil Tapes – Weather and temperature resistant qualities used for electrical cabling and permanent sealing
  • Protection Tapes – Used for protecting surfaces against daily corrosion

What Is Single Sided Tape Used For?

Single sided tapes can be used to replace traditional mechanical fasteners, such as: bolts, rivets and welds, as they offer a better aesthetic finish with the same amount of strength. They can also be used as surface protection, electrical bonding, sealing and filling purposes, and other domestic applications.

What Surfaces Are Best For Single Sided Tapes?

Single sided tapes are best suited for flat surfaces and can provide adhesion for low surface energy (LSE) materials such as glass or plastics.

What Are the Advantages Of Single Sided Tape?

Some of the advantages of using single sided tapes for your application include:

  • Provides vibration and noise reduction whilst using lighter, thinner materials
  • Provides a more efficient bonding solution, reducing assembly time whilst offering flexibility
  • Provides the ability to bond dissimilar materials
  • Provides an improved aesthetic finish that you cannot achieve with some mechanical fastenings
  • Provides a uniform thickness and gap filling properties whilst acting as a reliable moisture seal

Double Sided Tape

What Is Double Sided Tape?

Double sided tapes have an adhesive coating on both sides and also come under the category of pressure-sensitive components. This way, they are suitable to attach two materials together with a completely invisible bond.

What Kinds Of Double Sided Tape Are There?

There are many different varieties of double sided tapes that are suited to different types of domestic and industrial applications, some include:

  • VHB™ Tape – Very High Bonding tape which is suitable for heavy duty, industrial applications
  • Adhesive Transfer Tape – No backing material, just a silicone release liner
  • Foam Tape – Used for bonding dissimilar materials
  • Thick Bonding – Used for bonding uneven, textured surfaces
  • Thin Bonding – Used for thin gap filling requirements

What Is Double Sided Tape Used For?

Double sided tapes can be used for when you require an invisible bond, whether that may be for bonding parallel surfaces together or for display components. They can be used as an alternative to mechanical fastenings, much like single sided tapes, as they can be hidden whilst still providing strong adhesion.

What Surfaces Are Best For Double Sided?

Double sided tapes are best suited for flat surfaces, but some can be used for uneven, textured surfaces if required. Some suitable materials include: metals, sealed wood, paper and cardboard. Their performance is compromised if you use powder-coated metals or any other chemically adapted substrates.

What Are the Advantages Of Double Sided Tape?

Some of the advantages of using double sided tapes are similar to ones for single sided tapes including:

  • Provides the ability to bond dissimilar materials, especially ones with texture and uneven surfaces
  • Reduces assembly time and eliminates the need for surface refinishing
  • Provides a thinner and lighter alternative to mechanical fastening
  • Provides a uniform thickness and gap filling properties whilst reducing vibration and noise impact
  • Provides an improved aesthetic finish with the invisible bonding capability
