Beschreibung
Zusammenfassung:	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. L'invention porte sur une composition polyéthylène/COP mélangée à chaud utilisable pour la fabrication de films à forte transparence et faible coefficient de frottement comportant: d'environ 70 à environ 98 % en poids de résine de polyéthylène, et d'environ 2 à environ 25 % en poids d'un composant d'une première résine COP d'un poids moléculaire moyen d'environ 0,5 kg/mol à environ 50 kg/mol, et présente en quantité efficace pour accroître la capacité de glissement relative de films faits de ladite composition par rapport à des films constitués de la seule résine de polyéthylène.
