摘要： The present invention relates to a process for detecting a leak in a package. The process comprises preparing a package by covering at least a portion of an O 2 -sensitive product with a multilayer film comprising (i) a leak-indicator layer in which a O 2 - sensitive indicator is present throughout the leak-indicator layer; and (ii) an O 2 -barrier layer outward of the leak-indicator layer. A low O 2 -environment is provided within the package. The leak-indicator layer. A low O 2 -environment is provided within the package. The leak-indicator layer is then illuminated with light containing a wave-length absorbed by the O 2 -sensitive indicator, so that the O 2 -sensitive indicator produces an emission of radiation in an amount inversely proportional to a level of O 2 present with the O 2 -sensitive indicator. The then multilayer film is scanned while the O 2 -sensitive indicator is emitting radiation, the scanning being carried out by sensing and comparing the amount of radiation emitted from at least two different regions of the multilayer film.

The first layer is an outer heat seal layer containing a blend of a highly branched homogenous polymer and a semicrystalline polymer. The highly branched homogenous polymer has at least 40 branches per 1000 methylene groups, an Mw/Mn less than than 3.0, and a density of less than 0.89 g/cc. The highly branched homogenous polymer is present in an amount of from about 5 to 50 weight percent, based on layer weight. The semicrystalline polyolefin has a density of at least 0.90 g/cc. The semicrystalline polyolefin is present in an amount of from about 50 to 95 weight percent, based on total layer weight. The second layer contains a thermoplastic polymer in a crosslinked polymer network. A process for making a packaging article includes coextruding the first and second layers, irradiating the resulting multilayer film, and thereafter heat sealing the first layer to itself or another component of the packaging article.

摘要： A packaging laminate useful as a lidstock comprises first and second films, and an image between the first and second films. The first film comprises a sealant layer forming the inside surface of the first film. The first film has a free shrink at 220° F (104° C)in at least one direction of at least about 7 %. The second film comprises an outside layer forming the outside surface of the second film. The outside layer comprises at least about 40 % by weight of the outside layer of one or more relatively high-melt polymers each having a melting point at least about 25° F (ca. 10° C) higher than the lowest melting point polymer of the sealant layer. The second film has a free shrink at 185° F (85° C) of no more than about 10 % in each of the machine and transverse directions. The outside surface of the first film is directly laminated to the inside surface of the second film. The first film has an oxygen transmission rate greater than the oxygen transmission rate of the second film. The laminate has an oxygen transmission rate of no more than about lOO cubic centimeters.
