Abstract: In an embodiment, a monolayer, sealable film includes polyethylene; and between about 0.2 wt % and about 10 wt % of a branched cyclic olefin copolymer (bCOC) comprising: between about 50 wt % to about 98 wt % ethylene; and between about 2 wt % and about 50 wt % cyclic olefin derived monomer units. In another embodiment, a receptacle for containing organic material (such as food), gas, and/or fluent material includes a storage zone; a sealing zone extending around at least a portion of the storage zone; and a film structure having an exterior surface and a storage side surface facing the storage zone, wherein the film structure comprises a gas barrier film, comprising: polyethylene; and between about 0.2 wt % and about 10 wt % of a branched cyclic olefin copolymer (bCOC) comprising: between about 50 wt % and about 98 wt % ethylene; and between about 2 wt % and about 50 wt % cyclic olefin derived monomer units.
