Title (EN) RESIN COMPOSITION FOR FILM AND PROCESS FOR PRODUCING FILM USING THE SAME
(FR) RESINE POUR FILMS ET PROCEDE DE PRODUCTION DE FILMS UTILISANT CETTE RESINE
Abstract:
(EN) A resin composition comprising (A) a high density polyethylene having specified MFR, density and melt tension, (B) a propylene polymer having a specified MFR, (C) talc, (D) CaO and/or MgO, and (E) a surfactant, and giving a film which is excellent in strength, water resistance and moldability and has a paper-like texture and rigidity. A film is produced from this composition by an inflation film forming technique wherein the ratio of the bubble diameter to the minimum bubble diameter and the ratio of the length along the film drawing direction of the part having a specific diameter within the bubble to the die diameter are regulated within a predetermined range.
(FR) Résine comprenant (A) un polyéthylène de forte densité possédant des valeurs spécifiques de MFR, de densité et de tension à l'état de fusion, (B) un polymère de propylène possédant une valeur spécifique de MFR, (C) du talc, (D) du CaO et/ou du MgO, et (E) un tensioactif, permettant d'obtenir un film présentant d'excellentes caractéristiques de résistance mécanique, de résistance à l'eau et d'aptitude au moulage, ainsi qu'une texture et une rigidité similaires à celles du papier. On produit un film à partir de cette résine grâce à une technique de façonnage de film par soufflage, selon laquelle on fait varier dans une plage déterminée le rapport entre le diamètre des bulles et le diamètre minimum des bulles et le rapport entre la longueur dans le sens d'étirement du film de la partie présentant un diamètre spécifique dans la bulle et le diamètre de la matrice.
