There is a lot of concern from users about the heat generated onto avery labels run in a laser printer! But have no fear, our labels are specifically designed to manage and operate in these temperatures, but it should be understood that the paper or labels or whatever you are printing on is only subjected to the temperature for a very short time. However, you should not experiment with putting other materials through your laser printer, some materials will melt and you should leave all the experimentation to us were have tested all our laser labels! Furthermore we have a very wide range of materials, including Removable, Freezer, Block out, Glossy, Semi Glossy, Colours, Fluorescents, Metallic, and plastic grades in Tough White, Matt transparent and Gloss Clear. Which represents the widest, most developed range in Europe which is available either off the shelf or in guaranteed 5 day turnaround!
