摘要： Disclosed are single-sided stretch cling films having a cling layer, a release layer, and a core layer. The core layer is located between the cling layer and the release layer. The ding layer includes a blend of an olefin block copolymer and an ethylene-based polymer. The present films exhibit improved cling force compared to using a random ethylene copolymer in the cling layer.

摘要： The instant invention provides a composition suitable for stretch hood, method of producing the same, and articles made therefrom. The 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
3 , 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.
