ABSTRACT:
A slip sheet for receiving, handling, storing and shipping a unitized load of product is disclosed. The slip sheet includes lips preferably on two adjacent sides allowing it to be gripped and pulled onto a fork truck with the aid of a conventional push-pull attachment. The slip sheet includes a first or bottom sheet of paperboard having lip extensions, a pair of intermediate sheets of paperboard laminated to opposite ends of the bottom sheet and overlying the ends of the lip extension along a first side and the length of the lip extension on a second side, and a pair of top sheets of paperboard laminated to the bottom sheet and to the ends of the intermediate sheets and overlying the ends of the lip extension on the second side and the length of the lip extension on the first side. The slip sheet is thus made up of a single-layer paperboard center section, a three-layer paperboard laminate at the corners of the slip sheet adjacent the lip ends, and a two-layer paperboard laminate at the center sections of the lips and the sides of the slip sheet adjacent these center sections. The machine direction of the intermediate and top sheets are perpendicular to each other. The slip sheet of the present invention provides for a substantial decrease in the cost of materials over prior art systems without sacrificing performance.
