摘要： A modular disk coextrusion die is formed of a plurality of cells stacked together. Each cell includes an arrangement of thin annular disks, including at least a first cap disk, a first distribution disk, a first transition disk and a first spreader disk. The modular disk coextrusion die includes at least one channel disk having at least one inlet opening and at least two outlet openings per inlet opening. The thin annular disks are configured so that a first of the outlet openings of the channel disk is in fluid communication with the first distribution disk in the first cell and a second of the outlet openings in the channel disk is in fluid communication with the first distribution disk in the second cell. The channel disk provides for a more efficient utilization of space at the inlet of the modular disk coextrusion die and enables the feeding of up to twenty melt streams.

摘要： A barrier foam tray contains recycled reclaim of barrier foam. The tray comprises a sheet of foamed polystyrene (PS) having laminated to it a flexible barrier film. The foamed polystyrene part can have admixed therein from 0.0001% up to 30% by weight of the flexible barrier film. The barrier film contains a barrier polymer such as ethylene vinyl alcohol copolymer (EVOH). The tray is made by grinding laminate scrap and extruding reclaim therefrom with virgin polystyrene.

摘要： Polymeric, thin oriented films can be made by use of a combination of a hot blown process and a blown bubble process, i.e. a double bubble process. The resulting film has use in replacing PVC for in store stretch wrap applications. Very low density polyethylene, VLDPE, is an especially preferred material for this process. It may be used as a monolayer, or as one layer of a multilayer structure. In practicing the invention, the polymer is extruded and hot blown, and heated to a temperature above its orientation temperature. This heating can be accomplished by the use of a heated liquid reservoir or sock disposed at the lower end of the primary bubble, inside the bubble. The hot blown heated film is then passed through a first set of pinch rolls, re-inflated into a blown bubble, and collapsed at a second set of pinch rolls. Thin, tough and elastic packaging materials are obtained by this process.

摘要： In a multilayer flexible film sutable for medical solution packaging, film-derived extractables are controlled by the use of a small amount of a high molecular weight stabilizer in the outer layer of the film. Solution pH can be controlled by the addition of a carbonate of an alkali metal to at least one intermediate adhesive layer and/or the core layer of the film.
