Is the crystal label resistant to high temperatures? Is it durable? Can it be put into the dishwasher?

I am the owner of a printing shop specializing in custom printing. Crystal labels are very popular recently. Many customers have come to ask whether the crystal labels printed by our printers are resistant to high temperatures? Are they not strong? Can they be put into the dishwasher? Then let me share with you our UV crystal label firmness test

We are now testing these transferred items

Scrape the edge of the crystal label hard, there is no warping at all, the pattern is intact, and the fit is 100%

Then we put these items in a pot and boil them for 15 minutes (simulating the high temperature environment of the dishwasher), and keep boiling the whole time.

After boiling, use a dishwashing brush to scrub them vigorously to simulate the flushing force of the dishwasher.

No falling off after high temperature, after boiling + scrubbing, there are no bubbles or peeling on the edge of the crystal label, the pattern color is still bright, and the firmness is as good as before.

Of course, this can also depend on the material of the crystal label. The glue we use is a better one, which is safer and more reliable
