Abstract: A multilayer polyolefin film useful for packaging contains a core layer including from 20% to 100% by weight of the core layer of a polyethylene homopolymer having a density of between about 0.94 and about 0.97; an ethylene/alpha-olefin copolymer having a density of between about 0.94 and about 0.97; polypropylene; or a mixture thereof; from 0% to 80% by weight of the core layer of linear low density polyethylene, low density polyethylene, a copolymer of ethylene and vinyl acetate; or a mixture thereof; and a skin layer laminated to the core layer. The skin layer is a layer of linear low density polyethylene, low density polyethylene, a copolymer of ethylene and vinyl acetate; or a mixture thereof. At least one of the core layer and the skin layer includes at least 20% modern carbon. If desired, two skin layers may be laminated to opposing surfaces of the core layer.

Abstract: The present invention relates to reactive purge compound for cleaning polymer processing equipment wherein the reactive purge compound that includes i) at least about 50 wt.% of a polymeric carrier component based on the total weight of the reactive purge compound; and ii) a chain scission catalyst component dispersed in the polymeric carrier component; wherein a) the chain scission catalyst component includes a chain scission catalyst selected from the group consisting of at least one alkali metal hydroxide, at least one alkaline earth metal hydroxide, and any combination thereof; b) the reactive purge compound further comprises a water generating component; or c) both (a) and (b); wherein the reactive purge compound is a feedstock material in the form of a plurality of pellets, granules, rods, powder or other particles.
