My laminated items are curling! How can I make this stop?

If your laminated item is curling up or down after it’s gone through the machine, check your user manual for instructions for “film tension.” You’ll need to adjust either the top or bottom tension to correct this problem (typically, if the film curls upward, you’d adjust the bottom tension; if the film curls downward, you’d adjust the top tension). If your tension is correct but you’re getting waves toward the center of the web film as it comes out the back, you’ve probably got “heat waves,” and you’ll need to turn the temp down or slow your speed down a little bit.
