Abstract: An extrudable polypropylene blend combined with resins in precise amounts so that the resultant extruded film is easier to glue and is useable with hot melt adhesives. Mixtures of polypropylene and low density polyethylene are normally considered incompatible, but the contemplated blends which include 10-30% low-density polyethylene mixed with polypropylene give resin combinations runnable on a coater extruder and they produce a film having the advantages of polypropylene but which are no more difficult to glue than a film of low-density polyethylene.

Abstract: The present invention is directed to a method of preparing a carbonless paper by ink jet application of molten particles before or after application of capsules.

Abstract: An anti-spill liquid container is disclosed and taught wherein the center of gravity of the container/liquid combination causes the container to inherently roll to a predetermined, non-spill, position if the container is inadvertently "knocked over." The invention disclosed and taught is applicable to any generally cylindrical container and is particularly suitable for drinking cups as commonly used in the fast food industry.

Abstract: A method for adhesively bonding opposed paperboard surfaces to each other to form a strengthened bond in a paperboard product and paperboard products formed thereof, comprising the steps of (A) applying a green-strength adhesive to at least a portion of the first paperboard surface; (B) applying a styrene-butadiene latex adhesive or a modified styrene-butadiene latex adhesive as a strengthening adhesive to at least a portion of either the first or the second paperboard surface such that the green-strength adhesive is substantially offset from the strengthening adhesive when the first and second paperboard surfaces are positioned in an opposed relationship; (C) orienting the first and second paperboard surfaces such that they are opposed to each other: and (D) contacting the first and second surfaces together to form the strengthened bond.
