A reclosable package includes a pair of opposing walls, a reclosable seal and a barrier partition. The pair of opposing wall panels are joined along a pair of opposing sides and a bottom bridges the opposing sides to create a receptacle space having a mouth end opposite the bottom. The reclosable seal extends along the mouth end and includes first and second opposing reclosable elements. The first and second reclosable elements are releasably engageable to each other. The barrier partition comprises at least a first layer that is substantially impermeable to at least one of oxygen, nitrogen and carbon dioxide. The barrier partition extends substantially across the pair of opposing wall panels in the receptacle space.

A method for triggering an oxygen scavenging component of a container for packaging an oxygen sensitive material includes the steps of providing a container defining an internal space and having an internal oxygen scavenging component including an oxidizable organic compound, exposing the oxygen scavenging component to a source of actinic radiation, positioned within said internal space, at a wavelength, intensity, and residence time so as to provide a dose of actinic radiation sufficient to activate the oxygen scavenging component, and packaging an oxygen sensitive material in the internal space of the container whereby the oxygen scavenging component scavenges the oxygen from the internal space of the container. An apparatus and packaging system are also disclosed.

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 utilization of thinner sheets of material to form articles.
摘要:
A high barrier, multilayer laminate is disclosed that is suitable for forming packages that contain oxygen sensitive products. The laminate material has a coextruded multilayer material that includes from exterior to interior: i) an outside sealing and decorative layer, ii) a light barrier layer including an adhesive disposed interior to the outside sealing and decorative layer, iii) a barrier polymer layer disposed interior to the light barrier layer, iv) an oxygen scavenger layer including an adhesive disposed interior to the barrier polymer layer, and v) an inside sealing layer disposed interior to the oxygen scavenger layer. A further laminate structure suitable for forming a package containing an oxygen sensitive product is also disclosed. The further laminate includes a first layer of linear low density polyethylene, a carbon black layer including an adhesive disposed interior to the first layer of linear low density polyethylene; a layer of EVOH disposed interior to the carbon black layer, an oxygen scavenger layer including an adhesive disposed interior to the EVOH layer, and a second layer of linear low density polyethylene disposed interior to the scavenger layer.
摘要:
A wrapping material for wrapping an item, such as a floral grouping is provided. The wrapping material has a bonding material on a surface so that, when the wrapping material is formed into a wrapper, the wrapper may be releasably attached to a mounting surface, such as a board or wall, by way of the bonding material.
摘要:
The present invention provides a wall for a package, which wall comprises, or includes a layer comprising, a composition comprising a polymer and capable of scavenging oxygen through the metal-catalyzed oxidation of an oxidizable organic component thereof. The oxidizable organic component is preferably itself a polymer, and may be the only polymer in the composition. Preferred compositions include a blend of 96% polyethylene terephthalate and 4% poly (m-xylyleneadipamide) containing 200 ppm cobalt as catalyst, with good permeance-versus-time performance (3) when formed into a bottle.
