摘要： The invention provides a multilayer film (10) having an oxygen transmission rate of about 10,000 cc (STP) /m 2 /day/atm or greater at 23 °C and 0 % relative humidity, a modulus of about 15,000 psi or greater in at least one direction. The multilayer film (10) can be used for packaging a wide variety of products requiring regulation of oxygen permeability under varying packaging conditions because the multilayer film is capable of providing a relatively high OTR without sacrificing the mechanical properties that may be necessary for many packaging applications. The multilayer film (10) may include a sealant layer (12), a stiffening layer (14), and a core layer (16) disposed between the sealant (12) and stiffening (14) layers. In one embodiment, the sealant layer (12) comprises a plyethylene having a density of less than 0,93 g/cc; the core layer (16) consists of an ethylene/alpha-olefin having a density of 0,90 g/cc or less; and the stiffening layer (14) comprises a styrene/butadiene/styrene block copolymer having a modulus of about 250,000 psi.

摘要： The presently disclosed subject matter is directed to a system and method that allows on-demand oxygen generation within a package (10). Particularly, the disclosed package (10) incorporates a mass of an oxygen generating material within the interior or exterior of the package (10). The oxygen generating material is contained by some means (55), for example, in a cartridge, pouch, sachet, or other similar article separate from a packaged product (40). For applications with fresh red meat, at the time the package is ready for display, oxygen generation is initiated to increase the oxygen concentration within the package interior, thereby allowing blooming of the red meat.
摘要翻译：目前公开的主题涉及允许在包装（10）内产生按需氧的系统和方法。特别地，所公开的封装（10）在封装（10）的内部或外部结合有大量的氧气发生材料。氧发生材料通过某种方式（55）包含在例如与包装产品（40）分开的药筒，小袋，小药囊或其它类似物品中。对于具有新鲜红肉的应用，在包装准备展示时，开始产生氧气以增加包装内部的氧浓度，从而允许红肉开花。

摘要： The presently disclosed subject matter is directed to an article (5) that enables on- demand blooming of an oxygen-sensitive product (10) packaged within the interior of the article. Specifically, the product can be packaged between two films (15, 20), wherein at least one of the films is oxygen-permeable. The edges of the films can be attached to one or more suspension frames (25, 30), such that the product is suspended between the two frames. An oxygen-impermeable material is provided that can be removed on demand to promote blooming.

摘要： A product is packaged in a pressure-reclosable package comprising a multilayer film having a heat-sealable, pressure-reclosable inside layer. The inside layer contains a hyperbranched polyolefin having at least 70 side chain branches per 1000 carbon atoms and a density of up to about 0.885 g/cc, and/or an ethClen5/alpha-olefin elastomer having a density of up to about 0.885 g/cc. The package is opened and a portion of the product removed, and a pressure-induced seal is used to re-close the package at a temperature of at least 11 °C. The reclosed package is then placed in an environment having a temperature of from about -50°C to +10°C, so that a cooled pressure-reclosed seal at least doubles in strength.
