3 Pack PTFE Teflon Sheet for Heat Press Transfer Sheet Non Stick 16 x 20 Heat Transfer Paper Reusable Heat Resistant Craft Mat

Sheets are about 70 microns / 0.0028 thick. Fabric is woven from flat strands (fiberglass?), then apparently coated with Teflon -- making the surface fairly smooth, but not optically smooth. One sees obvious surface texture under a jewelers loupe... maybe +/- 10 microns on each side. Both sides look the same. Used as release sheets, they may leave a slight pattern on glossy photographs dry mounted with low-temperature film at 185F; I dont find this objectionable, but photographs are noticeably less glossy after mounting. The cut edges of the fabric show a bit of fraying with short strands of fiberglass(?) protruding. The Teflon coating inhibits further fraying, but one should understand that the edge isnt a perfectly clean cut. This shouldnt matter for most applications.

This is the greatest little thing that I can reuse and reuse and reuse. 3 sheets came in my order and to date, I still have only used one. I use these to place over my vinyl on t-shirts and iron on top. I do this so I do not burn the vinyl and to distribute heat evenly. I also use this when some vinyl peels a bit on a shirt after wearing for a while I place on top and iron it back on. Love these sheets. Once I found here I stopped burning my vinyl.

Although I am sure these are excellent for baking (they remind me of thinner versions of the silpat mats we used to bake cookies for a certain sandwich chain) I bought this for crafting. I swear nothing sticks to these! So far I have tried: Hot glue School glue (white pva and glue sticks) Embossing powder and enamel Mod Podge E6000 Oil paint Acrylic paint Sharpies Alcohol inks/markers Clay (airdry and polymer) (Bonus! polymer clay can be molded on this, and carried straight to the oven to bake!) And nail polish My only wish is that it didnt slide around so much but I usually craft on a stainless steel table so I weight it with magnets. Wasnt great as a palette because of the color but it is translucent enough to put a stencil underneath and draw with glue! My son definitely had fun with that. The mats can be cut to size. I gave one to my son with his play doh set and told him to use that whenever he plays with play doh. Cleanup is a breeze with baby wipes or a damp cloth, even after the glue has dried. Be advised you should STORE FLAT OR ROLL GENTLY. Bending it will cause damage in the form of creases as is evident in my sons mat already! But with proper care I forsee these lasting a long time.

Just starting to use these more. Seem to work so far

This sheet works great when I use it with my heat press. It does tend to stick to the top of the press but it always peels right off. No damage or anything to either the sheet or the press. So u dont worry about it. Everything turns out great in the end.

Okay...so yeah, I see why its affordably priced. Not a good quality, very thin and definitely not the color I expected. The item also arrived creased and looked like it was taken from an older stock. I do think itd still be heat resistant and I just need my countertop protected, thats all I need it for anyway. I just hope itll last thats the only thing I doubt itll be because it creases so easily. I couldve done better but as long as it does that, I dont need it to be pretty.

I took a chance and cut these up to fit my freeze-drying trays so I wouldn’t have to use parchment paper anymore, which always has to be cut to fit the trays. To my surprise, it actually worked. Food doesn’t stick to the sheets, and they are easy to wash. This is going to save me a lot of money, and I will definitely buy these again if they ever wear out, which doesn’t look likely. I’m very pleased with my purchase.

Works great and very durable

These mats are huge! At almost 1.5 times the size of a half-sheet pan, and easily cut to fit, I was able to use just 2 of them to cut roasting/baking mats for a half-sheet pan, 2 quarter sheet pans, and also cut 2 slings to use to remove pot-in-pot bowls from my pressure cookers. I still have an entire sheet and part of another left. I dont know anything about using them for crafty things, I bought a nearly identical mat that I cut to a 13 round several years ago. I use it with my baking stone for pizza (baked at 500F) and bread. It has held up beautifully and sticky doughs slide off easily. I paid as much for that one (half sheet size) as I did for all 3 of these much larger mats. Theyre a bonafide bargain and I highly recommend them. If I could give them 10 stars, I would!

good value for the money
