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

This is quality shrink wrap, but best suited for larger tumblers (i.e. 32oz). It will work for 20oz tumblers, but needs to be trimmed about 1.5 inches from the top. Also, when using it for 20oz tumblers, the extra wrap will take longer to shrink fully around the tumbler. It works, but a smaller size would be better for 20oz tumblers. Hence my 4/5 rating. Our lessons learned: Use the low setting on your heat gun to avoid burning through the wrap while shrinking it. Always put a piece of butcher paper down on the grates of the oven to prevent the shrink wrap from melting to the metal grates.

I tried twice, it melted, ripped and burned in the oven so it burned my tumbler. It had a strong smell and made mess both times.

Don’t waste your money. No matter how light I applied heat .. holes appeared. Useless shrink wrap! If I could give it a zero, I would.

I bought these to do sublimation in my convection oven. I still haven’t been able to figure them out. Or it could be the oven too. These tend to melt in my oven.

Worked for my tumblers. I ordered a bigger size but it worked for what I needed ! Glad it was a quick delivery too !! Thanks.

It was to big for 20ounce cups

They are functional. You kinda have to figure out your own method though. I was trying to follow the directions they sent and the plastic kept melting in the oven. I found that keeping it at 300 for 6-10 minutes was perfect. If you use your heat gun used to shrink the wrap too close to the preferations they will rip.

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.

This is by far the worst shrink wrap i have ever seen. It melt while I was trying to shrink it. Then it stuck to the cup and my oven. Just awful
