Microporous films comprising a polymeric composition and a filler, wherein the film has an average water vapor transmission rate of at least about 16,000 grams H.sub.2O/24-hour/m.sup.2, a hydrostatic head pressure of at least about 300 mbar, and a basis weight of from about 5 gsm to about 50 gsm.

A mattress for a patient support apparatus has a cover having bottom and top surfaces, and an inflatable section disposed between the bottom and top surfaces. The inflatable section has a plurality of upper bladders in fluid communication with each other and a plurality of lower bladders in fluid communication with each other. The upper and lower bladders are selectively inflated independently from each other. The upper and lower bladders are formed by three sheets including an upper sheet, a lower sheet disposed below the upper sheet, and an intermediate sheet disposed between the upper and lower sheets. The upper sheet is fixed to the intermediate sheet to define the upper bladders between the upper sheet and the intermediate sheet. The lower sheet is fixed to the intermediate sheet to define the lower bladders between the lower sheet and the intermediate sheet. Other aspects of the mattress are also disclosed.

Provided is a stretchable film having excellent stretchability and excellent air permeability. Also provided is an article including such stretchable film. The stretchable film of the present invention includes an olefin-based resin and a filler.

The stretchable porous film of the present invention includes voids in a surface thereof, in which: the stretchable porous film has an air permeability measured with an Oken-type air permeability meter of less than 99,999 sec/100 cc; the stretchable porous film has such an extending direction that an air permeability measured with the Oken-type air permeability meter in a state in which the stretchable porous film is extended by 100% becomes less than 60,000 sec/100 cc; and the stretchable porous film has such a pulling direction that when, in a hysteresis test, the stretchable porous film is pulled from a width of 20 mm and an inter-chuck distance of 30 mm to an inter-chuck distance of 60 mm at a pulling speed of 50 mm/min and held for 1 minute, and then the pulling of the inter-chuck distance is released, a residual strain becomes 10 mm or less.

An environment sensitive coating system is disclosed that includes a pressure sensitive component comprising a first portion of an oxygen sensitive light emitting material dispersed in an oxygen permeable binder; and a pressure reference component comprising a second portion of the oxygen sensitive light emitting material dispersed in an oxygen impermeable binder.

Apertured elastic films include a polyolefin, a styrene block copolymer, a non-styrene block copolymer, or a combination thereof. Methods for forming polymeric films and articles of manufacture prepared therefrom are described.

Stretched elastic films include a polyolefin, a styrene block copolymer, a non-styrene block copolymer, or a combination thereof. Methods for forming polymeric films and articles of manufacture prepared therefrom are described

The present disclosure is directed to laminated articles, such as articles for food and beverages, that are biodegradable and/or paper recyclable. The articles include a substrate comprising a film layer. The film layer is formed from a film made from biodegradable and/or paper recyclable polymer materials. The film layer is resistant and/or impermeable to liquids The article is capable of being frozen and/or heated using, for instance, a microwave oven without delaminating.

Described herein is a UV/HEVL-filtering SiHy contact lens that not only has a relatively high UV/HEVL filtering capability but also has an aesthetic appealing color. The bulk silicone hydrogel of the UV/HEVL-filtering SiHy contact lens comprises repeating units of (1) at least one hydrophilic vinylic monomer, (2) at least one siloxane-containing vinylic monomer and/or at least one polysiloxane vinylic crosslinker, (3) at least one UV-absorbing vinylic monomer having an absorption peak at a wavelength of from 280 nm and 380 nm, (4) a first HEVL-absorbing benzotriazole-containing vinylic monomer having an absorption peak at a wavelength of from 410 nm and 420 nm, (5) a second HEVL-absorbing benzotriazole-containing vinylic monomer having an absorption peak at a wavelength of from 415 nm and 425 nm, and (6) from about 90 ppm to about 300 ppm of repeating units of at least one polymerizable blue dye.

A lyophilization container includes a first section having a first layer, a second layer aligned with the first layer, and a cavity defined by the alignment of the first and second layers, where at least one of the first and second layers is preformed to have a three-dimensional shape. A lyophilization fixture includes a base member and a lid member. The lid member is movable between a first position and a second position relative to the base member. The base member and lid member together define a housing that receives at least a portion of a lyophilization container.
