Abstract

Se trata de sachets laminares de polímeros de buena adaptacion ambiental, fabricado de una estructura laminar de interpolímero de etileno linealhomogéneamente ramificado para envasar materiales fluidos tales como leche. Dichos sachets secaracterizan porque comprenden: (I) de 10 a 100 por cientoen peso de al menos un interpolímero de etileno/alfa-olefina lineal homogéneamente ramificado que tiene: (a) un CDBI mayor de 50 por ciento; y (b) unadistribucion del peso molecular, Mw/Mncomprendido ent re 1,5 a 2,5; y (II) de 0 a 9 por ciento en peso de al menos un polímero seleccionado del grupoque consiste de: interpolímeros de etileno/alfa-olefina (C3-20) substancialmente lineal, homogéneamente ramificado, copolímeros deetileno/alfa-olefinaC13- 18 lineal heterogéneamente ramificado, polietileno de baja densidad, alta presion y copolímeros de acetato de etileno-vinilo. También de propone unprocedimiento para fabricar dichos sachets.These are polymer laminar sachets of good environmental adaptation, made of a homogeneously branched linear ethylene interpolymer laminar structure for packaging fluid materials such as milk. Such sachets are characterized in that they comprise: (I) from 10 to 100 percent by weight of at least one homogeneously branched linear ethylene / alpha-olefin interpolymer having: (a) a CDBI greater than 50 percent; and (b) a molecular weight distribution, Mw / M understood between 1.5 and 2.5; and (II) from 0 to 9 percent by weight of at least one polymer selected from the group consisting of: substantially linear, homogeneously branched ethylene / alpha-olefin (C3-20) interpolymers, C13-18 linear ethylene / alpha-olefin copolymers heterogeneously branched, low density, high pressure polyethylene and ethylene vinyl acetate copolymers. It also proposes a procedure to manufacture such sachets.
