Application
The 3/16" size is commonly used as a backing board for paintings, and maybe incorporated into framing packages for works on paper (normally separated by a vapor barrier). The 1/2" thickness is frequently used as a material for tray-pack style crate interiors or to fabricate lightweight inner boxes for both 2D and 3D objects. sometimes used to provide a support in storage where extra rigidity is required. Product grade needs to be carefully chosen to suit the application.
