发明名称 PROCESS FOR PRODUCTION OF MULTILAYERED STRUCTURE
摘要 Provided is a method of producing a multilayered structure, comprising the steps of: obtaining a regrind (C) by grinding a multilayered structure (B) having a layer of a resin composition (A), followed by sieving; and obtaining a multilayered structure (F) having a layer of a resin composition (E) made by melt kneading the regrind (C) and a polyolefin (D), wherein the resin composition (A) contains a polyolefin (G), a saponified ethylene-vinyl acetate copolymer (H) having an ethylene content of from 20 to 65 mol% and having a degree of saponification of vinyl acetate units of 96% or more, a saponified ethylene-vinyl acetate copolymer (I) having an ethylene content of from 68 to 98 mol% and having a degree of saponification of vinyl acetate units of 20% or more, and an antistatic agent (J), and a mass ratio (H/I) is from 0.1 to 10. According to this, using a regrind of a multilayered structure having a resin composition layer containing a polyolefin and an EVOH enables to provide a method of producing a multilayered structure that is suppressed in generation and worsening of uneven cloudiness.
