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

360 degrees and it melted down n the bottom of my oven

Ordered these before all the reviews started to pour in and I can say they are terrible. They are not for sublimation. They melted with just the heat gun. I ruined 2 tumblers until I went back to check the reviews and realized it wasn’t user error. These are going back.

This product says it’s good up to 400 degrees. It’s not. I put it on my cups and it melted at less than 400. Do not recommmend this product. If I could return them I would but unfortunately I tried a couple thinking it was my error but no it wasn’t.

Delivered quickly, easily to use with heat gun and makes job so much simpler.

It couldn’t handle 350 degrees and ruined tumbler! Not happy at all

The temp from the heat gun (on low) to shrink these to the item makes them melt and disintergrate before you can start sublimation.

Works perfect. Holds my image just as is should. Will purchase more as soon as I need them.

I like it because it’s already cut and ready to uae

I purchased this for sublimating tumblers I was so disappointed the three times I used it. They melted too easy when applying heat and bubbled while in the oven after three minutes. Buy

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.
