Can I use laminating pouches thinner than 80 micron?

The minimum heat setting is enough for an 80 micro pouch and thus should be slightly too hot for say a 70 micro pouch. In reality this just might mean that the thinner pouch laminates not so well and you get waves in the plastic… It also depends on the quality of the pouch, so we advise against laminating low quality thin pouches as there is a good chance this might become trapped in the laminator.
