Multi-layer barrier film

Abstract: A delamination resistant multi-layer film comprises a core layer of vinyl alcohol polymers or copolymers such as polyvinyl alcohol or ethylene vinyl alcohol. Adhered to the core layer are one or more layers of a polyolefin blended with a chemically modified polyolefin having functional groups added to the basic polymer such that strong adhesion to the core layer is obtained. The core layer provides an excellent oxygen barrier, while the adjacent layers protect the core layer from degradation by exposure to water vapor. Additional layers of various polymer materials may be provided over the layers of modified polyolefin. The film can be prepared by coextrusion techniques.

Drying agent in multi-layer polymeric structure

Abstract: In a multi-layer polymeric structure having an interior oxygen barrier layer of a moisture sensitive polymeric material such as ethylene-vinyl alcohol, drying agents are incorporated in the structure, particularly in a layer or layers proximate to the barrier layer, to limit the moisture content of the barrier layer to maintain barrier properties.

Retortable packaging structure

Abstract: Retortable packaging is made entirely with polymeric materials. The improved heat sealable structure has an inner heat seal layer of linear low density polyethylene. The second or adjacent layer is linear low density polyethylene with an optional 0% to 80% medium density polyethylene blended into it. A third layer is anhydride modified medium density polyethylene. Fourth, fifth and sixth layers respectively are nylon, ethylene vinyl alcohol and nylon. An optional layer between the second and third layers is at least 20% linear low density polyethylene and up to 80% medium density polyethylene. The entire multiple layer structure is firmly adhered together so that the layers mutually support each other in the unitary package.

Multi-ply fibrous sheet structure and its manufacture

Abstract: In the manufacture of a multi-ply fibrous sheet structure, each of a pair of plies of fibrous web material is provided with a spot embossed first pattern defined by inwardly directed nested protuberances that are adhesively joined at distal surfaces thereof to confronting surfaces of the opposite ply, and the adhesively joined plies are provided with a spot embossed second pattern defined by registered, unidirectionally presented protuberances in each of the joined plies and fitted compactly one within the other.

Application of the Cube-Per-Order Index Rule for Stock Location in a Distribution Warehouse

Abstract: Consider a distribution warehouse divided into reserve storage and staging areas. The warehouse stores a variety of items and receives orders for any combination of items. Goods are moved from reserve storage to staging area, where they are selected to fill the given orders. The problem is to locate items in the staging area in order to minimize the expected labor costs of order selection. Several years ago, J. L. Heskett [Heskett, J. L. 1963. Cube-per-order index---A key to warehouse stock location. Transportation and Distribution Management3 April 27--31.] proposed a criterion, called the cube-per-order index CPO rule, for solving this problem. The criterion was justified heuristically by means of numerical examples. Recently [Kallina, C. 1976. Optimality of the cube-per-order index rule for stock location in a distribution warehouse. Working paper, American Can Company, March.], one of the authors has shown that the class of problems considered by Heskett can be formulated as a linear program, and that the CPO rule is in fact the optimal solution. In this present paper, we will 1 summarize some basic background material, 2 describe the computational steps for implementation of the CPO rule, and 3 discuss some practical conclusions gathered from experience in actually applying the rule to assist in warehouse layout.
