<p>Multi-layered corrugated containers having at least one flat side, have at least one foldable flap attached at the fold line to the flat side. In the past the fold line has been scored or crushed after the box is formed, and this represents an additional manufacturing step. The container includes a multi-layered sleeve with at least one flap on one end of the sleeve and a fold line separating the flap from the sleeve, the fold line having a strip with no corrugations therein permitting the flap to be bent about the fold line.</p> |
