Estimating the term…
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/cm3, a total heat of fusion less than 120 Joules/gram and a heat of fusion above 115° 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.
