Need a laminated poster? inkchaser offers several different types of lamination films. A 1.3 mil film is the lightest option and can be rolled. A 3 mil film provides more rigidity. If you need to write on your poster and wipe it off, select a write on/wipe off film. For posters that will be exposed to extreme sunlight for an extended period of time, a UV inhibitor film will provide long term protection.
