摘要： A method for producing an internally reinforced aeolotropic thermoplastic film web through coextrusion of two polymeric materials, and more particularly, a method of forming a film web possessing an enhanced tensile strength in at least the longitudinal or machine direction of the film web. A plastic film having internal striplike reinforcements entirely embedded within a matrix material is formed by the inventive method, and such film is utilized for various articles; for instance, plastic bags, bag components such as handles by liners, stretch wrap film, and the like.

摘要： The present invention relates to thermoplastic bag structures which are characterized by having a pair of carrying handles formed integrally with the bag walls and extending upwardly from opposite sides of the open mouth portion of the bag. Specifically, such handled bags are particularly characterized in having reinforced handle members where the handles comprise at least two layers of thermoplastic material, one of the layers imparting tensile strength to the individual layer and the other layer particularly employed to provide the requisite puncture and tear resistance necessary in such a bag structure.

摘要： A thermoplastic bag characterized by having handles formed on opposite ends of the bag mouth which is characterized by having structural features immediately adjacent the mouth of the bag to provide stress relief at those positions on the bag mouth where maximum stress is concentrated when such bags are being filled with product and eventually carried by the user. The stress redistribution feature is characterized by an area or areas, immediately adjacent the mouth portion of the bag and the base of the handle members, which are characterized by having a plurality of narrow pleats which are impressed into the bag structure by die members during formation of the individual bag.

摘要： 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 contains microcavities formed by the addition of a cavitating agent. 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.

摘要： 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 regions.
