Abstract: In order to stabilize stacks of cartons of consumer products which have ultra-low friction, glossy, point of sales graphics surfaces, on a pallet, without having to package the cartons in an outer container such as a corrugated cardboard box or the like, high-friction tie sheets are used between each superimposed layer of the carton. Each tie sheet has opposed ultra-high friction surfaces with a coefficient of friction of at least 0.8, up to 0.9 or even higher to itself.

Abstract: To increase the compression strength of a corrugated cardboard box, the horizontal edges of the box are perforated and the vertical edges are chemically treated. Surprisingly, the combination of mechanical and chemical treatments increases the compression strength more than the figure obtained by adding the percentage strength increases attributable to the individual treatments.

Abstract: A shirt is packaged on a flexible shirt board without the need for pins or clips to maintain the integrity of the folded shirt by using a shirt board which is coated with a transient adhesive. In the folding process portions of the skirt are adhered to the transient adhesive by a steam iron. A transient adhesive coated collar board may also be used to support the shirt collar. To unpackage the skirt, it is simply unfolded and pulled away from the shirt board at the adherent portions. A preferred form of transient adhesive for use in the process is also disclosed.

Abstract: A composition is disclosed, which when applied to the surface of a paper product, such as a corrugated board, improves the slip-angle. The composition, consisting of an aqueous suspension of colloidal silica and urea, finds particular utility in products resulting from recycled paper.

Abstract: Effective control of warp in the manufacture of corrugated paperboard sheets on standard corrugator equipment is achieved by the on-line application of a regulated quantity of moisture to one or both sides of the completed corrugated paperboard web after it has been heat-bonded together, while it is still hot from the heat-bonding operation, and prior to its being cut into individual corrugated paperboard sheets. By proper selection of the quantity and placement of the moisture application treatment, it is possible to counterbalance the net effect of the warp-producing conditions developed within the bonded paperboard web prior to and during its bonding operation, so that the resulting paperboard sheets leaving the corrugator will be consistently substantially flat. The moisture application treatment is carried out with an adjustable moisture spray system designed to selectively apply to either or both sides of the bonded paperboard web a variable regulated quantity of moisture.
