摘要:
A package which allows for butchering and packaging of fresh red meat at a centralized facility is provided which includes a an impermeable tray supporting the product, a first film sealed to the tray for enclosing the product, means defined within the first film for exchanging gases into and out of the package, and a second impermeable film enclosing the first film, such that removal of said impermeable film provides for the exchange of gases into and out of the package. The means for exchanging gases may be perforations defined within the first film, a second highly permeable film sealed to the first film, or an enlarged opening formed within the first film which is enclosed with a patch following adequate gas exchange at retail. Such gas exchange is required to release any low oxygen atmosphere and allow for the introduction of oxygen to the packaged meat product. Said means for exchanging gases having a gas transmission rate of at least about 50,000 cc/m.sup.2 /24 hrs./atm. at 73.degree. F.

摘要:
A method of detecting the permeability of an article to oxygen is disclosed. A fluorescent redox indicator, preferably riboflavin, is dispersed in a carrier and placed on an impermeable substrate. The article to be measured is placed adjacent to the carrier. Residual oxygen is removed, the redox indicator is photoreduced, the article and carrier are exposed to oxygen, and the indicator is exposed to UV light.

A forensic evidence container includes a first flexible panel, the first flexible panel including a material having a moisture vapor transmission rate of at least 10 gm/24 hours-100 square inches; a second flexible panel, the second flexible panel including a material having a moisture vapor transmission rate of equal to or less than 5 gm/24 hours-100 square inches; an opening capable of providing access to the interior of the forensic evidence container; an adhesive, applied to the first panel or second panel, having a free surface so arranged as to seal the opening on superposition of the first panel and the second panel; and a tamper evident device arranged on the first or second panel. A peelable flexible third panel, including a material having a moisture vapor transmission rate of equal to or less than 5 gm/24 hours-100 square inches, can optionally be peelably adhered to the first flexible panel.

摘要:
The present invention relates to the non-invasive use of a luminescent compound to detect and measure concentrations of oxygen dissolved in a rigid container, especially a bottle, a tray, a carton, a lidstock associated with a tray, a stand up pouch, or a paperboard container. The measurement is made independent of the oxygen concentration of the surrounding atmosphere. The invention is especially useful as a quality assurance check to verify oxygen scavenger activation during the assembly of bottled products, and modified atmosphere and vacuum packages. The method according to the invention is faster and less wasteful than previous methods that rely on measuring oxygen concentration within the headspace of an assembled package.
