Plasticize blueprints and certificates with this Fellowes Caliber A3 laminator. Choose the thickness of the cover you insert and it will automatically heat up within a minute. Because of the HeatGuard function, the housing stays cool, so you do not burn your fingers on the device. Thanks to a built-in sensor, the laminator prevents jamming sleeves and automatically performs again. This ensures that your documents are not damaged. Do you not use the device for 30 minutes? Then it switches itself off so that you do not consume power unnecessarily.
