This unique thermal response is one of the features that set PLS laminators apart from the rest that use heated rollers. Many other laminator manufactures produce laminators that "run out" of heat after a few turns of the rollers, sometimes after only a couple of feet. Most heated rollers (other than ours!) have a tendency to lose enough heat resulting in incomplete lamination and subsequent bond failure. Our Revolution Series Rollers are designed to produce a consistent and perfect thermal output allowing you to have a predicable and sustainable thermal response while laminating thus taking the guess work out of the more unusual tasks.
