I'd call Loc-tite's consumer help line, 800.624.7767, describe the material and texture as best you can and ask for an adhesive recommendation. They undoubtedly have something that will bind Velcro to the plastic ceiling panels. You may have to go to Fastenal or Grainger to get it. As you've already experienced, removability without damage to the panel is a key factor in adhesive selection so be sure to ask about that, too.
