It's a bit pricey but the Xyron is perfect for the type of glitter application you are wanting to do. You could also buy sticker paper and peel off the top part to apply glitter.
I use Aleene's Clear Tacky Glue for glitter but it will buckle if it's a large area. You could also try brayering liquid glue on your paper. I have done this before. My paper did not buckle.
