ADHESIVE COMPOSITION AND SOFT PACKAGING MATERIAL COMPOSITE FILM

摘要

An adhesive composition and soft packaging material composite film that can reduce the amount of low-molecular-weight compounds leached into the contents of composite film, can enhance the oil resistance without detriment to the inherent performance of contents, can prevent a marked strength decrease even when the contents are oily and can exhibit satisfactory flexibility so as to avoid a decrease of peel strength. For providing these, a polyurethane polyester polyamide polyol and/or polyester polyamide polyol containing amido bond obtained by reaction between a dimer acid and a polyamine is produced as a polyol component. Further, the concentration of cyclic compound comprising an amido bond and/or ester bond in an extract water resulting from extraction of a composite film obtained by bonding with the adhesive composition with water amounting to 0.5 mL /cm<2> based on the unit area of composite film is adjusted to 0.5 ppb or less in terms of dibutyl phthalate measured by gas chromatography flame ionization detector.
