Lamination to achieve smooth surface over plywood
Lamination is a valid term to use in your application. Countertops are often laminated with Formica™ but I would not consider it to be a product to be rolled on in a manner similar to wallpaper.

I tossed a search to the world wide interweb for "thin laminate" and found a product I was unaware existed. 

It's called cabinet veneer sheet and is produced and sold in various thicknesses and with various patterns. I've seen figures for 1/32" thickness with paper backing (implying self-adhesive) and poly backing, again self-adhesive.

One would expect that you've sanded the plywood prior to application and used a tack cloth or other method to remove sawdust. Read and follow all label directions to get the best bond possible.
