When you’re applying heat transfer vinyl (HTV) to a t-shirt or any other blank, one essential piece of information to know is the peel temperature. Peeling the carrier sheet off HTV at the wrong temperature can prevent the HTV from sticking properly and can damage the finish on shiny or textured HTV. So, is Siser HTV hot or cold peel?

The answer is yes, no and both. Siser HTV comes in a lot of varieties and some can be peeled hot, but some require you to wait and do a warm or cold peel.

In this article, I list all of the hot, warm, and cold peel Siser HTVs and show you how peeling HTV at the wrong temperature can ruin your vinyl.

What do you mean by hot peel or cold peel?

When you are using HTV or iron-on vinyl, the material is made up of two thin layers: the vinyl that will end up on your shirt or other blank, and the carrier sheet. The carrier is a film, usually transparent, on top of the heat transfer vinyl. It “carries” your HTV after its been cut and weeded, and after you’ve pressed the HTV, you peel the carrier sheet off and leave the now-adhered vinyl behind.

(You might also be familiar with the carrier sheet as the film your HTV sticks to when you are weeding. When you weed the excess vinyl from your cut design, you are removing it from the carrier sheet.)

Right after you press your HTV, the carrier sheet – and vinyl – will still be hot. HTV that is labelled “hot peel” can have the carrier sheet removed right away. “Warm peel” or “cold peel” HTV requires you to wait until the HTV has cooled off significantly.

I have a handy reference chart available for download that contains all of the time and temperature settings for every Siser HTV product. It also includes helpful, accurate information on peel temperatures, pressure and layerability. There is a separate chart for using Siser HTV with the Cricut EasyPress as well.

What Siser Heat Transfer Vinyls are Hot Peel?

Siser’s lineup of HTV includes 17 different varieties. The vinyl types listed below are labelled “hot or cold peel” meaning the carrier can be peeled off immediately after pressing. Please note that when HTV is labelled hot peel, it is not required that the carrier be removed while hot. If you have other things on the go, you can remove the carrier sheet from your vinyl at any temperature.

Why doesn’t the carrier peel off my HTV?

If you have tried to peel the carrier off the vinyl and it won’t cleanly peel away, it means it needs more press time. Apply heat for a few more seconds then try peeling again. Follow the time guidelines from Siser – pressing for long periods of time does not ensure a better bond with the fabric. In fact, over-pressing can weaken the adhesive bond and prevent the HTV from sticking to your base material.

What Siser HTV is Cold Peel?

These Siser products are labelled cold peel – that means you need to wait until the HTV has cooled off completely before you remove the carrier. If you remove the carrier too soon, you could damage the finish or lift the vinyl off the base material.

How do you cool down HTV faster?

There are a couple of tricks you can use to make your HTV cool faster so you can remove the carrier:

  1. After pressing, quickly remove your teflon cover sheet and any pressing pillows or mats you are using, because these can all hold heat.
  2. Flip your garment over and rub it over the cool surface of the table top. Rub it for a few seconds and then feel the carrier. If it’s still warm, try rubbing some more or hold it up and gently air it out. This should work to speed up the cooling process significantly.
  3. If you don’t want to move your item between presses, use an acrylic cooling block to reduce the temperature of your vinyl. These thick cut, smooth acrylic blocks help diffuse heat from the vinyl and the carrier sheet and speed up the peel time.

What Siser HTV is Warm Peel?

There are a few Siser HTV varieties that require a short wait to peel the carrier while warm. Make sure you pay attention to the label on your vinyl, because if you try to peel too soon, you can lift up the HTV or damage the finish.

How long do you have to wait for warm peel HTV?

You should wait 15 to 20 seconds before peeling the carrier sheet on warm peel HTV. If it doesn’t peel cleanly, repress for a few seconds, wait for another 15 seconds before you try to peel again.

More HTV carrier peel tips

You can peel the carrier off Siser HTV even if you haven’t pressed it for the full recommended time. This is key if you are pressing multiple layers. The Siser EasyWeed family of HTVs have a 1-second tack, meaning you can press for one second, then peel the carrier according to the instructions (hot, cold or warm). Then you can add another layer of HTV and press your project again. Keep track of the accumulated time to make sure you are not over-pressing your bottom layers! Non-EasyWeed Siser HTV can generally be tacked with a 3-5 second press.

You can press peeled vinyl under a teflon or parchment paper cover sheet. This helps protect the vinyl from scorching or discoloring because of direct contact with the heat platen.
