MANUFACTURING METHOD OF LAMINATE AND LAMINATE MANUFACTURED THEREBY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a laminate which suppresses the discoloration of a recycle layer and also can suppress the occurrence of phase-separated foreign substances (gummy build-ups). SOLUTION: The manufacturing method of the laminate comprises manufacturing a laminate having a layer containing (A) an ethylene-vinyl acetate copolymer saponification product having an ethylene content of 10-60 mol% and (B) an ethylene-vinyl acetate copolymer saponification product having an ethylene content of≥70 mol%, and a recycled layer produced by melt-forming a recovered material from a laminate having a polyolefin resin layer (C). The content of the (B) in the recovered material subjected to melt-forming is adjusted to≥0.001 wt.% and <0.3 wt.% based on the total amount of the (A) plus (C). COPYRIGHT: (C)2009,JPO&INPIT
