How is the film loaded into the laminator?
Most thermal roll laminators use two rolls of lamination film. One roll goes on top and the other on bottom. The two rolls of film are loaded onto mandrels. The diameter of the core depends on the laminator. The top and bottom roll are usually wrapped around a few bars and fed through the machine. Be sure the rolls are not on backwards as it could gum up your machine. You can see film loaded onto a roll laminator here.
