A multilayer film comprising a first layer comprising from greater than 0 to 100 percent by weight of an ethylene/&#x3b1;-olefin interpolymer composition (LLDPE), based on the total weight of the film composition; and a second layer comprising at least 5 percent by weight of the second layer, of an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin interpolymer having a density in the range of from 0.855 to 0.900 g/cm; and having a melt index (190&#xb0; C./2.16 kg) of greater than 200 g/10 min; and from 60 to 95 percent, by weight of the second layer, of EVOH is provided.

Multi-layer films and articles made therefrom

In an embodiment, a flexible bag is provided and includes opposing flexible films composed of a polymeric material. The flexible films define a common peripheral edge. The flexible bag includes a microcapillary strip located between the opposing flexible films and extending along a portion of the common peripheral edge. A peripheral seal extends along at least a portion of the common peripheral edge. The peripheral seal seals the microcapillary strip between the opposing flexible films. The peripheral seal forms a closed compartment. The flexible bag includes an amount of a flowable solid particulate material (FSPM) in the storage compartment.

Flexible bag with microcapillary strip

A film composition comprising from 5 to 75 percent by weight of an ethylene/&#x3b1;-olefin interpolymer composition (LLDPE), and from 25 to 95 percent by weight of a propylene/&#x3b1;-olefin interpolymer composition, and films made from the film composition, wherein the films exhibited synergistic physical properties, namely holding force and elastic recovery, are provided.

A reaction system comprising an organic polyisocyanate and an isocyanate reactive component for preparation of a viscoelastic polyurethane foam is provided. The isocyanate reactive component comprises (i) from 10 to 50% by weight of one or more low equivalent weight propylene oxide rich (PO-rich) polyols having a combined number average equivalent weight from 200 to 500, (ii) from 45 to 95% by weight of one or more ethylene oxide (EO-rich) polyols having a combined number average equivalent weight from 200 to 800 and an ethylene oxide content from 40% to 65% by weight of the total mass of the EO-rich polyol and at least one of (iii) from 10 to 30% by weight of one or more high equivalent weight PO-rich polyols having a number average equivalent weight from 800 to 2,000 or (iv) from 10 to 40% by weight of one or more propylene oxide co-polymer polyols containing styrene-acrylonitrile.

Process for making low compression and high airflow MDI viscoelastic polyurethane foam

Methods of forming olyurethane foams that are the reaction product of at least one polyisocyanate and a polyol composition are provided. The polyol composition includes at least one natural oil based polyol and at least one poly(propylene oxide) polyol and is desirably free of non-natural oil based polyols made from alkylene oxide units, other than propylene oxide units. The natural oil based polyol is present in a quantity sufficient to increase the processing window for the foam relative to a foam made using the same process and the same components, absent the natural oil based polyol. As a result, the present foams can provide very open-cellular structures with the superior performance properties of a poly(propylene oxide) polyol-based foam.

A reaction system comprising (a) a polyisocyanate component and (b) an isocyanate reactive component for preparation of a polyurethane foam having high air flow with low compression set is provided. The isocyanate reactive component comprises (i) from 45 to 70% by weight of one or more PO-rich polyols having a combined number average equivalent weight from 210 to 510, (ii) from 20 to 30% by weight of one or more ethylene oxide polyols having a combined number average equivalent weight from 200 to 500, (iii) from 10 to 25% by weight of one or more ethylene oxide-alkylene oxide polyethers having a combined number average equivalent weight from 300 to 800; and (iv) from 0.5 to 15% by weight of one or more PO-rich polyols having a functionality of 1 to 4 and a combined number average equivalent weight of 2,000 to 6,000.
