Patent ID: 10172764

Abstract:
Disclosed is an infusion bag film including: a surface layer which is formed of a polyamide resin composition; a heat sealing layer which is formed of a polyethylene resin composition containing a polyethylene as a main component; and an adhesive layer which is provided between the surface layer and the heat sealing layer, in which the polyamide resin composition is obtained by blending 0.05 parts by mass to 1 part by mass of hydrotalcite with respect to 100 parts by mass of a polyamide resin formed of one or more of Nylon 11 and Nylon 12. An object of the invention is to provide an infusion bag film which has reduced eluate in a pH test, that is, has high hot water resistance even when a polyamide resin, which can be heat-sealed in a short period of time at a high temperature, but has a problem in the hot water resistance in some cases, is used in a surface layer, and an infusion bag using the infusion bag film.
