Abstract: A melt-blended polyethylene/COP composition suitable for making optically clear films with low coefficients of friction includes from about 70 to about 98 weight percent of a polyethylene resin and from about 2 to about 25 weight percent of a first COP resin component, the first COP resin component having a weight average molecular weight of from about 0.5 kg/mol to about 50 kg/mol and being present in an amount effective to increase the relative slip value of films made from the composition as compared with a like film made from the polyethylene resin alone.

Abstract: A cycloolefin copolymer resin having a Hunter b color value of less than 1.0, which resin comprises: (a) a first cycloolefin copolymer having a glass transition temperature of from about 100 °C to about 220 °C and an intrinsic viscosity of from about 5 to about 1000 ml/g as measured in decalin at 135 °C, (b) up to about 10 % by weight, based on the total weight of the resin, of a second cycloolefin copolymer, said second copolymer having a glass transition temperature of greater than about 50 °C and an intrinsic viscosity of from about 1 to about 500 ml/g as measured in decalin at 135 °C, and (c) from about 0.01 % to about 3 %, based on the total weight of the resin, of at least one lubricant selected from the group consisting of fatty acid esters of aliphatic polyhydric alcohols, with the proviso that the glass temperature of the second cycloolefin copolymer is at least 25 °C lower than the glass transition temperature of the first cycloolefin copolymer, said resin being suitable for use in precision optical applications.

Abstract: A packaging film or sheet having a styrene-butadiene block copolymer directly melt-bonded to at least one layer of a cyclo-olefin copolymer is disclosed. The films may be made by means of co-extrusion. The packaging film is amenable to thermoforming processes and is particularly suitable for forming blister packaging used in pharmaceutical applications.
