Your Jackson Flat & Smooth® 7300 laminator has adjustable heat so it can laminate thick or thin plastics. We offer laminating pouches as thick as 30 mils total (15 mils each side) and as thin as 6 mils total (3 mils each side). One mil equals 1/1,000 inch. Changing the heat is as simple as turning the Heat Dial.
The appropriate Heat Setting is listed on the front of the machine, and there is a thermometer on the side so you can see when the temperature has settled.
