ABSTRACT:
An improved L-type backing board insert for supporting food, such as shingled bacon slices, in a film wrapped package is disclosed comprised of a two-ply laminate. An opaque flexible base ply of pigmented plastic material, such as high density polyethylene, is printed on one side and is provided with a mat finish on the other side. A window aperture is formed in the opaque base ply for viewing both sides of a portion of the packaged bacon. A ply of transparent polyolefinic film, such as polypropylene film, is adhered to the base ply, substantially covering the entire printed face and forming a window over the window aperture formed in the base ply. Use of the polypropylene film provides the backing board with a high gloss finish.
The improved two-ply backing board reduces the amount of ink necessary for printing on the backing board, captures the printing between the two layers of the laminate, and yields an inexpensive, flexible and high quality backing board.
