Container With Edge Protection Features
A container for holding a food product includes a bottom wall, a side wall, and a flange extending from the side wall. The bottom wall, the side wall, and the flange include a base layer, and the bottom wall and the side wall cooperate to at least partially define a cavity of the container. The container also includes an interior surface at least partially forming the cavity, an exterior surface opposite the interior surface, and an edge at the flange that extends between the interior surface and the exterior surface. A coating at least partially covers the base layer and at least partially defines the interior surface, and the edge includes an uncoated portion of the base layer. A protective strip covers the edge and prevents fluid from passing into the uncoated portion of the base layer at the edge.
