8x12 Inch Sublimation Shrink Wrap Sleeves, 60 Pcs White Sublimation Shrink Wrap for Tumblers, Mugs, Cups and More

I used to use a mug press for my tumblers but I had trouble with uneven heat and pressure so I decided to try the convection oven and shrink wrap method and Im so glad I did. These sleeves are super easy to use and give me even pressure all over.

They melted at 350. Actually, they started melting with just my head gun.

First of all the heat gun was barely blowing and not at the high temp and it immediately started to make burn holes in the wrapper exposing the sublimation paper I had underneath it. I figure I would still just put it in the oven to sublimate my tumbler. Then it melted onto the silicone mats. When we took it out of the oven to unwrap it, the rest of the wrap had more holes throughout it and the wrap literally became hard plastic chunks that you had to literally take something to chip off the pieces of the plastic just to get to the sublimation paper to take off the cup. You can see the bottom of the cup has hard burn plastic pieces on it and as I took a little pick to pop off the hard pieces it would pull off the paint as well.

Have not actually used these to wrap a Cup, Mug or Tumbler yet but when I hold them in my hands they are nice and think and you can just feel the quality with which they are made. Ill update this review once Ive used the wraps but I expect my Sublimation projects to come out beautifully with these aides.

This stuck to the tumbler and won’t come off. The bottom and top edge of the tumbler didn’t have sublimation paper on it, so when I stick the whole assembly in the convection oven, this stuff shrunk more and permanently fixed itself to the parts of the tumbler that were bare.

Se derriten y es casi imposible quitarlo de las superficies

I got these in hopes I could do some 30 oz tumblers...I did the normal process and this thing melted to the tumbler and NOTHING will get it off...wasted a tumbler. If anyone has any tips that would be great.

These are such poor quality, they completely melted into the cup, had to throw it away.

These are awful. They melt and bubble at temperature above 300. Sublimation requires 350-400 degrees to even work, so these are useless. Hard to get them to even shrink to the cup with a heart gun without melting. They also stick to the cup and are impossible to remove.

The shrink wrap melted to my sublimation over grrr
