Sublimation tape that works.
Number of Items: 2
Very strong and sticky tape. Great to use for sublimation on tumblers. No residual left on tumblers. Holds amazing. Stretch is just enough to help you get things nice and tight.

Durable, Odorless, and Reliable — A Must‑Have 3‑Pack
Size: 3Pack 16"x20" Black
I’m really impressed with this 3 Pack PTFE Teflon Sheet for Heat Press (16 x 20"). The quality is excellent, and the non‑stick surface makes every press come out clean and smooth. One thing I really appreciate is that there’s absolutely no smell, even when using high heat. It makes the whole process more comfortable and professional.
These sheets offer great protection for both the heat press and the materials. They prevent scorching, keep the plates clean, and stop any vinyl or ink from sticking. My projects come out more consistent because the sheets help distribute heat evenly and act as a reliable barrier.
The 3‑pack is a huge bonus. I keep one on my press, one as a backup, and one for different materials like HTV or sublimation. It saves time and keeps everything cleaner when I’m working on multiple items.
The 16 x 20 size is perfect for shirts, tote bags, and larger designs, and the sheets stay flat without curling. If you want something that protects your equipment, has no smell, and delivers clean results every time, this set is definitely worth it.

T shirt Quilt Use
Size: 3Pack 16"x20" Black
I bought this specifically for ironing interfacing onto t-shirts before cutting into squares. Some of the memory t-shirt's had ‘puffy paint’ and other shirts had uncertain designs that may be ruined by ironing without protection or by using just a pressing cloth (cotton material). A teflon sheet was suggested on a you tube video to ‘play it safe’ when making a memory quilt. I felt the heat resistance teflon helped because you need to hold iron in same place for a longer time than ‘regular ironing’ movement. It worked well, the only (minor) issue is you can’t see through it. It did not interfere at all because positioning of shirt and interfacing was in place. I’m a ‘newby’ at this process; this worked for me. This is a good quality material; one sheet can be used for ironing t-shirts forever, I plan on using the other two teflon sheets to line outdoor BBQ drawer.
