The present invention relates generally to the packaging materials. More specifically, the invention relates to materials and methods suitable for use as packaging materials whereby the appearance of grease, fat or oil staining on the packaging material is reduced or eliminated.

Grease masking packaging materials and methods thereof

A multipurpose, two-position ladder attachment for extending a ladder above overhanging roofs while bridging the eaves and gutters, for leaning against weak siding, and for installing heavy or bulky panels or windows in elevated openings. Elongated channels formed in two cantilevered brackets are clamped about the stiles of the ladder by a rod and wing nuts. The rod passes through hollow rungs of the ladder or in close proximity to the stiles if the rungs are not hollow. A flat padded board connected across the free ends of the brackets is positionable with its broad side horizontal or vertical when the ladder is leaned at a recommended angle.

Multipurpose ladder fixture

Apparatus for testing the abrasion resistance of a printed area on a carton which is also subjected to flexing during the abrasion process. The apparatus includes means for holding the two carton samples in proximity to each other while one sample is oscillated over and abraded with the other. One of the samples is provided with a raised center portion to simulate flexing of the carton samples as they are abraded.

Apparatus for testing abrasion resistance of printed surfaces

A press-formed plastic coated paperboard tray is hermetically sealed by applying a hot melt or wax to indentations (e.g. relief depressions or wrinkles) formed in a flange of the tray at the corners of the tray. A film cover is then adhered to the tray over the flange and the hot melt or wax filling the indentations in the corner of the flange of the tray provides a hermetic seal for the interior of the tray and its contents, such as sterilized medical instruments, and precludes leakage of liquids housed within the tray.
