Abstract: A laminated multilayer film substrate for use in the production of banknotes having an oriented polypropylene core layer and at least one high density polyethylene layer on each side of the oriented polypropylene layer. The core layer may contain microcavities formed by the addition of a cavitating agent. The outer surfaces of the multilayer film substrate are coated with one or more epoxy layers, filed or unfilled, and one or more antistatic layers. The resultant films exhibit good embossability, dead-fold characteristics and other properties, making them highly suited for the production of bank notes and other security documents.

Abstract: A laminated multilayer film substrate for use in the production of banknotes having an oriented polypropylene core layer with print features and at least one high density polyethylene layer on each side of the oriented polypropylene layer. The resultant films exhibit good embossability, dead-fold characteristics and other properties, and are difficult to counterfeit, making them highly suited for the production of bank notes and other security documents.

Abstract: A laminated multilayer film substrate for use in the production of banknotes includes a first layer comprising (a) a first layer having inner and outer sides, comprising at least about 50 weight percent of a high density polyethylene having a density of at least about 0.94, said first layer being oriented in the transverse direction (TD) to a degree which is at least three times greater than the degree of orientation present in the machine direction (MD); (b) a second layer having inner and outer sides, comprising at least about 50 weight percent of a high density polyethylene having a density of at least about 0.

Abstract: A laminated multilayer film substrate for use in the production of banknotes having an oriented polypropylene layer and at least one high density polyethylene layer on each side of the oriented polypropylene layer which are preweakened to eliminate delamination. The resultant films exhibit good embossability, dead-fold characteristics and other properties, and are difficult to counterfeit, making them highly suited for the production of bank notes and other security documents.

Abstract: A laminated multilayer film substrate for use in the production of banknotes. The film substrate includes a first layer comprising at least about 50 weight percent of a high density polyethylene having a density of at least about 0.95, the first layer oriented in at least a first direction to a degree which is at least three times greater than the degree of orientation present in a direction substantially normal to the first direction, and a second layer comprising at least about 50 weight percent of a high density polyethylene having a density of at least about 0.95, the second layer oriented in at least a first direction to a degree which is at least three times greater than the degree of orientation present in a direction substantially normal to the first direction, wherein the second layer is laminated to the film substrate so that the first direction of orientation of the second layer is substantially normal to the first direction of orientation of the first layer.

Abstract: A bag structure of a thermoplastic film material comprising front and rear bag walls connected by side walls and having an open mouth top portion, said open mouth portion being characterized by having handles located at opposite end regions thereof, said handles being of two films as a result of being integral extensions of said front rear and gusseted side walls, said bag having a bottom wall planarly extensible so as to form a rectangle with at least no substantial excess film outside of the bulk volumetric capacity of said bottom region of said bag.

Abstract: A dispensing system for a package of a continuous, severable sheet material comprising a number of individual severable members, such as plastic bags, separated by transverse pre-weakened regions, such as perforations, is composed of a storage container holding the package and a dispensing device. The dispensing device is separate from and is located at a location remote from the storage container. The continuous severable sheet material is conducted to the dispensing device and is threaded therethrough until the pre-weakened separating two consecutive members emerges through the exit of the device. A sufficient force is then applied to the continuous, severable sheet material to separate the two consecutive members from each other at the pre-weakened region.

Abstract: A method for forming a one-sided cling stretch wrap film by adhering a particulate antiblock to one surface of the film while the surface is in a semiplastic state, applying a particle-embedding force to the surface and removing excess particulate matter. The thermoplastic stretch wrap film exhibits a significant level of cling on one surface but no appreciable cling force on the other, the latter surface exhibiting a slide property when in contact with a film or like surface due to the presence of particulate antiblock agent mechanically bonded thereto. The film can be used to overwrap one or a group of articles to form a unitized packaged unit employing any of the known and conventional tension-wrapping techniques. Because of its one-sided cling and slide capabilities, pallet loads overwrapped with the film and in mutual contact avoid film tearing or destruction when the pallet loads are separated from each other.

Abstract: The present invention includes a new bag packaging system for open mouth bags made of flexible material, preferably a thermoplastic side gusseted bag with handles integrally formed therein, which provides a complete bag packing environment and includes a base member, a bag supply means secured to the base member, and bag-engaging elements supported vertically above the base member opposite the bag supply means at a distance and height for expanding the mouth of the bag and to secure the bag against collapse while loading. Furthermore, the present invention provides a means for continuously presenting a bag-detaching point to the packer which facilitates removal of the bags from the bag supply means and optimizes the loading area. A further feature of the present invention includes minimal structure which could hinder easy removal of the loaded bag from the system.

Abstract: The present invention is a method of continuously making thermoplastic film bags having one-side-free for separation from an opposite side. The method includes providing a continuous tube of thermoplastic film for formation of the bag, such tube having a continuous surface which forms opposing sides of the bags. The tube is directed to a bag forming means which continuously flattens the tube into at least the opposing sides of the bag. The tube must intermittently be partially severed on one of the opposing sides at intervals corresponding to single bag lengths, such severance being made at a location for providing detachable separation of the one wall from the opposing wall. Next a sealed seam is formed across the tube at intervals which provide bottoms to each of the bags, and the bags are then collected in a stack where they are substantially aligned followed by fusing the stack of substantially aligned bags adjacent the severance in the one side for separating the bags from stack one side at a time.
