    摘要： A container comprises a substrate and a multi-layer film The substrate has a bottom wall and a continuous base wall in which the continuous base wall encompasses the bottom wall and extends upwardly therefrom. The substrate comprises at least one particulate mineral filler and polypropylene. The multi-layer film is attached to the substrate. The multi-layer film comprises at least a first layer and a second layer The first layer comprises a metallocene-catalyzed polyolefin The second layer comprises polypropylene. The substrate and the multi-layer film are made in the absence of ethylene vinyl alcohol copolymer (EVOH), ethylene vinyl acetate copolymer (EVA), and ethylene methyl acrylate copolymer (EMA).

    摘要： A modified atmosphere packaging method creates a modified atmosphere in a package including an inner package and an outer package. The inner package is composed at least partially of a polymeric material substantially permeable to oxygen, while the outer package is composed of a polymeric material substantially impermeable to oxygen. After a food product such as raw meat is placed within the inner package, the inner package is flushed with a desired mixture of gases to substantially remove oxygen from the inner package. The flushed inner package is then sealed and inserted into the outer package without sealing the outer package. Next, the outer package is flushed with the desired mixture of gases to substantially remove oxygen from the outer package. After flushing the outer package, the outer package is sealed. An oxygen scavenger is provided in the package to substantially absorb any residual oxygen within the package. The oxygen scavenger is activated with an oxygen uptake accelerator to increase the rate at which the residual oxygen is absorbed.

    摘要： A method for producing an alkenyl aromatic polymer foam structure that comprises melting at least one alkenyl aromatic polymer resin. An effective amount of blowing agent mixture is dissolved in the at least one alkenyl aromatic polymer. The blowing agent mixture comprises at least one VOC blowing agent and acetone. The majority by mole percent of the VOC blowing agent is selected from n-butane, iso-butane, propane and combinations thereof. An extrudate is formed comprising the at least one alkenyl aromatic polymer resin, the at least one VOC blowing agent, and acetone. The extrudate comprises less than about 2.7 wt. % of the at least one VOC blowing agent. The extrudate is transferred to an expansion zone and permitted to expand to produce the foam structure. The foam structure has an extruded density less than about 7 lbs/ft3 and a basis weight of less than about 20 grams per 100 in2.
