HP Adhesive Polypropylene is Peeling!

[BethCanoe]

I work at a museum and we print and cold laminate our own exhibit panels.

We are currently using HP adhesive polypropylene laminated to .5" gator board and it is peeling off and looks awful. At this point we're looking at re-doing a whole exhibit of panels and signs, but I need to figure out what a better material to use would be, or why this peeling is occurring before we re-do it.

We've done this for years and only started having issues in the last two years.

Would photo paper and adhesive gator be a better option? Has anyone had this same issue?

Any help is GREATLY appreciated!

While you most likely have climate control out the yin yang in a place like that, evidently, you've either gotten bad media for the last two years, changed ink types or some other vital ingredient in your equation has mysteriously changed. If you can't afford to buy a flatbed, then outsource it to someone who has one. End of problems for peeling matters.

Not sure why you're using poly and laminating, I would think a standard vinyl w/laminate would work better. Have you changed the laminate you use? Are you prepping the panels different?
I would try a matched vinyl/laminate.

switch to HP Adheasive backed vinyl

That specific product is junk, we use their plain everyday matte poly and mount it with a gmi adhesive.

We need to do it in house, and did successfully for a while, so outsourcing for most of our needs isn't possible. We DO have climate control out the yin yang! Sounds like it might be bad media.

Ok, I think we'll try that. Would that be a better option than adhesive gator and a thicker photo paper?

Good to know! I wonder if we had maybe been ordering the vinyl before and somehow switched to the poly with our realizing.

I've always found it easier to apply adhesive back to a substrate than non adhesive to an adhesive substrate.

what printer are you using? HP5500?

Are you using the white clay coated or kraft paper gator board.

If you're mounting all your prints, switch to something like Gen. Form. 223. Thick vinyl, SUPER for mounting to boards. Can't even imagine why you would print to adhesive poly pro.
