ABSTRACT:
A blank for a paperboard container is provided on one of its surfaces with a layer of food-contacting polymethylpentene. The container formed from the blank, as by bending the blank along fold lines, requires one or more overlapped joints such as the usual manufacturer's joint. To overcome the non-stick properties of the polymethylpentene layer, the layer is flame treated so that it will adhere to a conventional water based, FDA approved adhesive and thereby make possible the formation of a seam or other overlapped joint or joints. Flame treatment is restricted to portions of the area of the polymethylpentene layer that are involved in the formation of the overlapped joint or joints.
