Laminating Film is Cloudy! What Can I Do?

Laminating Pouches & Film / TroubleshootingHave you ever run a picture or an important document through a pouch laminator only to have it come out with cloudy splotches all over it? It can be pretty frustrating, especially if it is something you really care about. So is there anything that you can do to fix the cloudy splotches? Here are a few tips.

You may have noticed, when you first place a document in a laminating pouch, that the film is translucent. That is because the glue, which lines the inside of the pouch, hasn’t been melted. Once melted, the glue becomes clear and stays that way. If the glue isn’t properly melted, some of that translucent cloudiness remains.

I would say 9 times out of 10, when cloudy splotches and spots appear, the laminator being used is running too cool. Some areas of the film melt and laminate properly, but the rest remains in an “unlaminated” state.

There are two things you can do to fix this problem. The first thing you can do is run your pouch through the laminator again and hope that a couple of passes will properly laminate the film. Your second option is to increase the heat of the laminator and run the pouch through. This should eliminate the cloudy spots.

If you are still noticing cloudy spots, even after adjusting the temperature or re-running the pouches through the laminator, your film may be too old or the laminator may be defective. If the film is too old, you’re probably out of luck and will need to buy new film. Unfortunately, the item you are laminating may be irreparably cloudy. I would certainly try at least running the pouch through another laminator before deeming the project a failure.

Some lower-end pouch laminators may require that you run the laminator through multiple times, every time. This is often the result of the laminator only having 2 rollers, which sometimes results in uneven heat distribution, or the laminator may simply have a week heating element.

For clean and clear results every time, I highly recommend using a laminator with 4 rollers or more. The more rollers used, the more evenly heat is distributed, which in turn produces great results.

Good luck!
