Sublimation Shrink Wrap Film,White 7x11 Inch Heat Sublimation Shrink Wrap Tube for Mugs, Tumblers,Blanks, Shrink Wrap Bands for Sublimation,50 Pcs

The first batch I bought was excellent quality, so I reordered, but the second batch was soooo bad. They were so much thinner and melted less than half way through sublimating my cups, which left the cups with less pressure. Ive ruined several cups trying to get them to work to no avail. I thought I would be getting the same product I got the first time, but no such luck. Very disappointing.

Still trying to get used to them but works great.

The shrink wrap shrinks easily. It does not allow the tumbler to get hot enough to allow the image to transfer completely. I followed the heating directions for metal tumblers, but any longer than 4 minutes the plastic began to melt and stink.

Worked exactly how I expected.

Very easy to use. Works great. No ghosting or uneven spots when baking sublimation tumblers in convection oven. Relatively easy to remove. Does melt when laying tumblers on oven rack so I started standing them up and no melting. However, even when it melted in spots, the transfer of ink was not impacted. I will buy again.

it help greatly in sublimating.

These are very easy to use and to get off, they do melt a little , they have melted to my oven while sublimating. I havent tried any other brands. They melt at 350F But they havent effected the quality of the product.

I used this on a 20 oz tumbler and it melted at 375. It has the potential to ruin your projects and cause costly waste. Returning.

Used it for the first time and completely melted in my oven! Beyond upset with this!

These sleeves are not for sublimation. The sleeves bubbled and burst at 330 leaving light spots in my designs. They melted onto several bottles and were impossible to remove without scraping the finish off. they cannot handle the temp and time required for sublimation. I tried multiple times to adjust my settings to see if it was user error, but no. I wasted nearly 10 bottles and cups trying to get the settings right but none kept from being ruined. I have since moved to another supplier and I am much happier.
