摘要:
A high barrier, multilayer laminate is disclosed that is suitable for forming packages that contain oxygen sensitive products. The laminate material comprises a first layer including biaxially oriented polyethylene terephthalate (20), a second layer of a high barrier oxide material (15) disposed exterior to the first layer (20), and a third layer of an adhesive material (45) disposed interior to the first layer (20) and joining the first layer to a fourth coextruded multilayer material (25). The fourth coextruded multilayer material (25) comprises from exterior to interior: i) a first layer of a polyethylene material (30), ii) an oxygen scavenging layer comprising a polyethylene and an oxygen scavenger material (35), wherein the oxygen scavenging layer is disposed interior to the first layer of the polyethylene material (30), and iii) a second layer of the polyethylene material (40) disposed interior to the oxygen scavenging layer. A further laminate structure suitable for forming a package containing an oxygen sensitive product is also disclosed. The further laminate comprises a first layer comprising biaxially oriented polyethylene terephthalate, biaxially oriented polyamide, or biaxially oriented polypropylene (80), a second layer of a high barrier oxide material (15) disposed interior to the first layer (80), and a third layer (45) joining the second layer (15) to a fourth layer of a polyethylene material (30). The third layer of adhesive material (45) includes an oxygen scavenger material.

摘要:
The present invention provides an oxygen-absorbing resin composition, which is capable of sufficiently causing the oxygen-absorbing reaction even in a low-water environment, and also provides a packing material, packing method and package using such oxygen-absorbing resin composition. This invention is an oxygen-absorbing resin composition which contains a resin and an oxygen absorber which is made by coating iron powder with sodium iodide and potassium iodide. In a multi-layered film formed from this resin composition, iron particles coated with sodium iodide, etc. are dispersed in an oxygen-absorbing resin layer (4). Since a reaction accelerator of the oxygen absorber contains sodium iodide and potassium iodide as its principal component, this multi-layered film sufficiently absorbs oxygen in a low-water environment.

A sheet-like or a film-like deoxidizing multi-layer material is herein disclosed which comprises an oxygen absorbing layer as a middle layer comprising an oxygen absorbing resin composition in which a deoxidizer composition is blended, a gas barrier layer as an outer layer comprising a gas barrier resin, and an oxygen permeating layer as an inner layer comprising an oxygen permeating resin, the gas barrier resin comprising a polyamide or a polyamide copolymer which contains 90 mol% or more of an amide structure unit produced by the polycondensation reaction of metaxylylenediamine with adipic acid.
摘要:
An article forming system for forming at least one sheet of material into an article, such as a decorative flower pot cover for example, and a novel article formed utilizing such a system. The article forming system includes a male die, a female die and a platform having a support surface and an opening extending through the support surface. The female die is disposed generally within the opening in the platform with the upper end of the female die being disposed near the support surface. The article forming system includes means for slidingly holding portions of the sheet of material generally against portions of the support surface while permitting such held portions to slide on the support surface during the forming of the article for cooperating in forming a decorative border on the decorative flower pot cover type of article which flares generally away from the flower pot object when the decorative flower pot cover article is applied to the flower pot. The article formed in accordance with the present invention includes overlapping folds formed by overlapping portions of the sheet of material to bring portions of the sheet of material into bondable contact, the overlapping folds providing the mechanical strength necessary for the formed sheet of material to hold a predetermined shape thereby permitting the utiliztion of thinner sheets of material to form articles.
