    Hi everyone,

    We have a small laminator that we use very little.

    We've been having a bubble problem lately.(look at the pic)

    we're laminating coated stock, 250 gsm, offset printed both sides.

    Film is BOPP base, 28 thickness. We've tried diferent temperatures and/or speeds with no success eliminating them. Most strange thing is that problem usually shows up a few minutes after start up but sometimes does not show at all.

    Any ideas wellcome

    Thanks

    Moe
