Abstract:
A multilayer nonporous oxygen absorbing structure that resists delamination, e.g., humidity induced delamination, including a first layer having a first continuous polymer phase, a first water insoluble, dispersed, polyether resin phase in the first continuous polymer phase, and a water activated oxygen absorber, and a second layer having a second continuous polymer phase, bonded to the first layer.
Abstract:
An apparatus for orienting articles includes a bowl having a sidewall and angled relative to horizontal, a disc disposed in the bowl and rotatable relative to the bowl, the disc having a radius proximate its outer periphery defining a groove sized to receive one of the articles in a predetermined orientation, and a diverter for diverting canisters contained in the groove through an outlet in the sidewall of the bowl.
Abstract:
An extruded or molded article containing iron based oxygen scavenger, electrolytes, activated carbon, silica gel, or other water absorbing media, and optionally pore formers, is subjected to deformation to create voids or porosity, and subjected to water spraying or dipping to obtain a water activity of 0.4 or higher. The article is placed in a container or package containing oxygen sensitive articles.
Abstract:
The invention generally provides a moisture barrier article comprising a polymer matrix with water vapor permeability equal to or below 1 g mm/(m2 day) at 90% relative humidity difference and the intended temperature of use between 15° C. and 30° C., and moisture absorbing particles dispersed in the matrix in an essentially uniform manner, wherein the moisture absorbing particles have an average diameter of between 1 and 15 micrometers and wherein the article has an average wall thickness to mean particle diameter of at least 10:1.

Abstract:
A horn for an ultrasonic welder includes a pattern of knurls on a face of the horn. The knurls are spaced by a pattern of indentations including fist indentations formed a first depth from a contact plane and second indentations formed a second depth from the contact plane.
Abstract:
A composition that absorbs oxygen and emits carbon dioxide in response to absorbing oxygen including ascorbic acid, an organic acid, a catalyst that promotes oxidation of the organic acid and emission of carbon dioxide and a soluble transition metal salt characterized by multiple oxidation states.
Abstract:
An oxygen scavenger includes a coated film formed as a sachet and an oxygen scavenger retained in the sachet. The coated film may include a spun-bonded polyolefin base layer coated with a USP-grade low density polyethylene. The resulting sachet is non-porous with a tunable permeability.
