Disclosed herein is a recyclable barrier film comprising a first layer comprising high density polyethylene; and a barrier layer comprising a polymer other than polyethylene; where the polymer is operative to reduce the oxygen transmission rate through the barrier film relative to the oxygen transmission rate through the first layer; where the barrier layer is present in the barrier film in an amount of less than 5 weight percent, based on the total weight of the barrier film. Disclosed herein too is a method of manufacturing the disclosed barrier film.

Barrier film, methods of manufacture thereof and articles comprising the same

The invention provides a composition comprising at least the following: A) an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin interpolymer having the following properties: i) a melt viscosity (177&#xb0; C.) less than, or equal to, 200,000 cP, ii) a density from 0.855 to 0.900 g/cc; B) an ethylene-based polymer; and C) a polar polymer.

Functionalized polymer compositions and films formed from the same

The instant invention provides a polyethylene blend composition suitable for blown film, method of producing the same, and films made therefrom. The polyethylene blend composition suitable for blown film according to the present invention comprises the melt blending product of: (a) less than or equal to 4 percent by weight of a low density polyethylene (LDPE) having a density in the range of from 0.915 to 0.935 g/cm, and a melt index (I) in the range of from greater than 0.8 to less than or equal to 5 g/10 minutes, and a molecular weight distribution (M/M) in the range of from 6 to 10; (b) 90 percent or greater by weight of a heterogenous linear low density polyethylene (hLLDPE) having a density in the range of from 0.917 to 0.950 g/cm, and a melt index (I) in the range of from 0.1 to less than or equal to 5 g/10 minutes; (c) optionally a hydrotalcite based neutralizing agent; (d) optionally one or more nucleating agents; and (e) optionally one or more antioxidants. When the polyethylene blend-composition is formed into a film via blown film process, the output rate is improved at least 6 percent relative to a similar linear low density polyethylene.

Polyethylene blend composition suitable for blown film, method of producing the same, and films made therefrom

The instant invention provides a composition suitable for stretch hood, method of producing the same, and articles made therefrom. The article according to the present invention comprises a multi-layer film according to the present invention has a thickness of at least 3 mils comprising at least one inner layer and two exterior layers, wherein the inner layer comprises at least 50 weight percent polyethylene copolymer having a melt index less than 2 grams/10 minutes, a density less than or equal to 0.910 g/cm, a total heat of fusion less than 120 Joules/gram and a heat of fusion above 115&#xb0; C. of less than 5 Joules/gram, the total heat of fusion of the inner layer less than the heat of fusion of either of the two exterior layers, and wherein the multi-layer film has an elastic recovery of at least 40% when stretched to 100% elongation.

Composition suitable for stretch hood, method of producing the same, and articles made therefrom

Composition for stretch hood, method of producing the same, and articles made therefrom

A multi-layer film structure is made from a specific polyethylene copolymer comprising the inner layer and is useful as a stretch hood film structure. The polyethylene copolymer can be characterized by a Comonomer Distribution Constant greater than about 45.
