You laminate it to hold a form, or apply it to a form. The form is usually made from cut ply wood sides and ribs going across. Often time a layer of bending plywood is laid over top of this to help finished project be smooth.
1: design a curved object
2: build a form to match the curved design
3: Apply the bending plywood to the form to get the thickness you want, with layers of glue between. It is often sold in 3/8” thicknesses, so you end up with 3/4” sheets.
4: clamp with a lot of clamps and cauls. sometimes strap clamps work for convex radii. When designing the form allow a little for spring back.
5: Remove clamps and proceed to finishing steps. you now have a curved object that will hold it’s shape.

here is a picture of the form used to make the bottom section of the banquet
