An Overview of PVC Tapes and Where to Use Them
Tapes are thin strips or rolls of material that feature adhesive on one or both sides. They are versatile tools that can be maximised by various industries in sealing, bundling, marking, repairing, mounting, and many more.
As of now, tapes can be made from various materials. One of the materials that can be used in manufacturing tapes is polyvinyl chloride or PVC.
Characteristics of PVC Tapes
PVC tapes feature several characteristics that make them useful in many industries. Some of these characteristics are as follows.
Durable: PVC tapes are durable and can withstand harsh weather conditions, chemicals, and moisture. These properties make them ideal for outdoor applications and industrial settings where exposure to harsh conditions is common.
Flexible: Another property of PVC tapes is they are flexible. Their flexibility allows them to be utilised on curved or uneven surfaces. They can also be torn easily by hand, which makes them convenient to use anytime and anywhere.
Effective: PVC tapes are not only durable and flexible, but they are also effective. They have a strong adhesive that allows them to stick to surfaces like metals, plastics, and fabrics. Their effectiveness makes them useful for sealing, bundling, and marking.
Insulated: PVC tapes are often used in electrical applications since they have strong electrical insulation and protection against moisture, heat, and abrasion. These properties allow them to be useful in protecting cables and wires.
Versatile: Many industries today can take advantage of PVC tapes that feature various colours, widths, thicknesses, and other physical properties. Their versatility makes these tapes effective in almost all applications from various industries.
Cost-effective: PVC tapes, ultimately, are easy to use. They can also be effective for many industrial, commercial, and household applications. All these capabilities make them cost-effective as they are not that expensive.
PVC Tapes Main Applications
All characteristics of PVC tapes make them useful in the following applications.
Electrical insulation: PVC tapes are commonly used in electrical applications for insulating and protecting electrical wires and cables. They provide good insulation and protection against moisture, heat, and abrasion.
Sealing and bundling: PVC tapes are also used for sealing and bundling purposes due to their strong adhesive properties. They can be used to seal containers, boxes, and bags and to bundle items together for shipping and storage.
Pipe wrapping: Aside from electrical insulation, sealing, and bundling, PVC tapes are also used to wrap and protect pipes and other components from corrosion, abrasion, and damage. They are commonly used in plumbing and HVAC applications.
Marking and labelling: PVC tapes are often utilised for marking and labelling purposes due to their ability to adhere to various surfaces. They are commonly used for marking safety hazards, identifying different products or parts, and labelling containers.

PVC Foam Tapes: Advantages and Applications
PVC foam tapes provide sealing and insulation against air, dust, moisture, impact, and vibration. These compressible, flexible tapes come in low, medium, and high densities and conform to tight curves and irregular surfaces. Because of how they’re made, PVC foam tapes speed installation since there’s no release liner for assemblers to remove. These assembly tapes also support roll slitting and die cutting for cost-effective material conversion and manufacturing.
Advantages of PVC Foam Tapes
The benefits of using PVC foam tapes begin with how they’re made. First, liquid polyvinyl chloride (PVC) is poured onto a casting sheet. Heat is applied, the closed cell PVC foam rises to a specified thickness, and an adhesive is direct-coated. Next, the foam is wound into a tape-grade roll. Unrolling the tape exposes the adhesive, which is on the inside rather than the outside of the tape. This construction eliminates the need for a release liner, which saves installers time on your assembly line.
PVC foam tapes can also reduce your material costs and meet precise dimensional specifications. Larger rolls called logs are cost-effective to buy, but they require material conversion. With lathe slitting, a tape converting process, a rotating blade cuts through a log to create multiple tape rolls with specific widths. In turn, these narrower rolls support die cutting. The PVC foam that’s in these die cut tapes provides inherent resistance to fire, sunlight, and many chemicals.
Applications for PVC Foam Tapes
PVC foam tapes are available in different densities and are used in automotive, HVAC, general industrial, building and construction, and other applications. Low density PVC foam tapes are a good choice for weather stripping and can replace polyurethane foam gaskets at a much lower cost. Medium density PVC foam tapes provide added strength and increased impact resistance. With their high internal strength, high density PVC foam tapes offer the highest levels of cushioning.
PVC materials are used as door and window glazing tapes, HVAC gaskets and vibration dampeners, and air seals in cleanroom ceiling panels. These slit foam tapes also provide general environmental sealing for access panels, and are used as roof curb seals on large, roof-mounted air handlers. In log homes, PVC foam tapes seal the gaps between logs. In motorcycle helmets, high-density PVC foam tapes provide additional cushioning.

What’s the Difference Between PVC Tape and Duct Tape?
If you need strong and durable tape for your application, PVC tape and duct tape might be on your shortlist of options to consider. So, which one should you choose? The answer comes down to how you’ll use it. As we covered in a previous blog post on choosing the right tape for the job, each solution has a different purpose. Just like you wouldn’t use scotch tape to seal ductwork, you wouldn’t use duct tape to wrap holiday gifts.
This article will look at the differences – and similarities – between PVC tape and duct tape to illustrate the ideal applications for each one, helping you build a better and smarter arsenal of packaging materials.
The Low-down on PVC Tape
Polyvinyl chloride tape, or PVC tape, is a thick and strong premium quality packaging tape designed to accommodate heavy-duty shipments, such as large parts or bulky supplies. It has a flat finish with a natural rubber adhesive that can bond to many surfaces, including cardboard. Known for its quiet release when pulled from the roll, it tape is exceptionally easy to work with because it doesn’t stick to itself, can be readjusted, and is very strong, making it a top-selling customer favorite.
Features of PVC Tape
• Strong, durable, and water-resistant
• Forms a strong bond on surfaces, including cardboard
• User-friendly because it doesn’t stick to itself
• Flat finish with rubber adhesive
• Choose from varying thicknesses, widths, lengths, and colors
• Custom printing available using up to three colors
Best application for PVC tape: heavy-duty packaging. PVC is best for applications requiring durable and thick custom packing tape, such as shipping large parts or heavy supplies.
Next, let’s look closer at the characteristics of duct tape to distinguish it from PVC tape.
The Low-Down on Duct Tape
Duct tape is composed of strong fabric bonded to polyethylene film with a rubber adhesive. As its name implies, duct tape was initially developed for sealing air ducts, with its silver-gray color blending almost seamlessly with metal ductwork. As it grew in popularity, new versions emerged with varying fabrics, films, and adhesives to accommodate many home and commercial repair tasks. However, duct tape does not adhere well to cardboard, making it unsuitable for most packaging applications.
• Flexible, sturdy, and sticky
• Water-resistant adhesive designed primarily for repairs and industrial uses
• The rubber adhesive does not bond well to cardboard or hot, cold, wet, uneven, dirty, or painted surfaces
• Easily tears by hand
• Available in general-purpose, industrial-grade, professional-grade, gaffer’s tape, stucco tape, and coated cloth tape
Best application for duct tape: home or commercial repairs. Duct tape is best for sealing and repairing applications requiring thick tape with a sticky adhesive, such as sealing air ducts.
In the next section, we’ll summarize the number one difference between PVC tape and duct tape.
The Primary Difference Between PVC Tape and Duct Tape
Before we drive home the difference between PVC tape and duct tape, let’s explore a few features that they share. They are both thick with a strong adhesive and have water-resistant properties. While these tapes are similar to each other, the important question to ask yourself is: What do you need it to accomplish? Do you need to repair something? Are you shipping a heavy-duty package?
PVC tape is an excellent solution for packaging because it bonds well to cardboard boxes. Because cardboard’s surface is porous and contains fibers that can break away, duct tape’s bond is prone to failure. So, when it comes to mastering the art of packaging, go for PVC tape for a premium quality tape that can stand up to your heavy-duty shipping needs.
