What are heat seal tapes?

These tape is a PTFE coated glass cloth tape with an adhesive backing. It is usually brown in color but can be offered in other colors such as food grade blue. The adhesive that is used to stick this in place is a special high temperature resistant silicone adhesive which has an easy to remove yellow crinkled release liner.

 

What type of machines use these tapes?

Machines that use heat seal tape are more often than not pieces of equipment used within the packaging industry. An example of this would be an L-sealer. An L-sealer works by using a hot nickel chrome wire to cut through a thin plastic film which effectively heat seals a given product within a pouch.

The heat seal tape is used as a heat resistant barrier between the hot wire and the film being cut / melted. The heat seal tape also is a non-stick product so any molten film does not stick to the PTFE (also referred to as Teflon).

 

What types of tapes do you offer?

We offer a few different styles of heat seal tape which range from have adhesive fully on one side or with double sided adhesive strips which are known as barrier, zone or duplex tapes.

Here is a quick run-down of the types we offer.

 

Tefsil 3 Adhesive tapes

This is the thinnest we offer and is popular due to its low cost and ease of thermal transfer. The coated weight of this product (excluding the adhesive) is 150g/m2 with a 5% tolerance on this.

 

Tefsil 5 Adhesive tapes

This is the most common heat seal tape we supply and is very popular with OEM’s. It is a premium grade version and has a total coated weight of 250g/m2. Many companies tend to offer this but with only 230g/m2 so it is always worth checking when comparing prices.

 

Tefsil 6 Adhesive tapes

This grade uses the same base fiberglass as Tefsil 5 adhesive but has even more PTFE coating. This brings the coated weight up to 300g/m2. Again this is a premium product with many companies offer products with 260g to 270g/m2.

 

Tefsil 10 Adhesive tapes

This has a coated weight of 480g/m2 per square meter and is manufactured on a heavier fiberglass glass to Tefsil 5 & 6 adhesive. This is usually used underneath the nickel chrome wire and tends to be requested at 20mm wide.

What is the most common type of heat seal tapes you offer?

We sell an awful lot of our Tefsil 5 Adhesive. This is because it has a really high percentage of PTFE coating compared to the versions our competitors offer and is well suited to a wide range of heat seal machines.
