The purpose of the present invention is to provide: an EVOH-based resin composition (pellets) which has been made to have a desired melt viscosity without heightening the boron content and which is hence effective for surging prevention; and a process for producing the composition. The EVOH-based resin composition contains a boric acid compound, wherein the boric acid compound includes boron atoms of a tetracoordinate structure. A paste of an EVOH-based resin is brought into contact with an aqueous solution containing both a boric acid compound and an alkali metal salt in such amounts that the EVOH-based resin comes to contain the alkali metal salt in an amount of 300-1,000 ppm of the EVOH-based resin, at an elevated temperature and an elevated pressure. Thus, some of the boron atoms in the boric acid compound can be converted into tetracoordinate atoms.

A packaging bag for packaging polyvinyl alcohol resin for melt molding, the packaging bag comprising a film having a methanol vapor permeability of 0.5-1000 g/m2 • day. A method for storing polyvinyl alcohol resin for melt molding in which granules of polyvinyl alcohol resin for melt molding are sealed and packaged using the packaging bag comprising the aforedescribed film. Accordingly, packaging the polyvinyl alcohol resin for melt molding using the packaging bag yields a polyvinyl alcohol resin such that the organic solvent remaining in the sealed polyvinyl alcohol resin turns to vapor and passes through the packaging bag before being released to the outside air and volatilizing, the organic solvent concentration being lower after storage in the packaging body. As a result, it is possible to provide a polyvinyl alcohol resin for melt molding in which molding stability is improved.
