Description of the Related Art Infusion containers have been widely used in recent years in place of conventional glass containers because of their light weight, toughness, and ease of handling. This plastic infusion container is classified into a bag type and a bottle type. The bag-shaped infusion bag is made of a polyolefin resin such as polyethylene or polyvinyl chloride, and the infusion to be filled is an amino acid infusion agent, an electrolyte infusion agent, a sugar infusion agent, or the like.

法を提供するものである。However, since the amino acid infusion solution is deteriorated by oxygen, the amino acid infusion solution bag needs a gas barrier property for long-term storage and transportation. Polyvinyl chloride, which has a relatively good gas barrier property, has a risk of elution of the plasticizer contained in the resin into the infusate, and the polyolefin resin has a problem of poor gas barrier property. As described above, for example, polyester (303) / polyvinylidene chloride (302) / unstretched polypropylene (301) having polyvinylidene chloride or ethylene / vinyl alcohol copolymer resin as a constituent material on the outside of the infusion bag (200). It was double-wrapped with the exterior material (300) of the multilayer film having the structure. The present invention provides an infusion bag made of a polyolefin resin, which is provided with gas barrier properties at the same time as the main body is formed, and which does not require double wrapping with an outer packaging material of a multilayer film, and a method for producing the same.
