To provide an adhesive polymer composition capable of being formed into a sheet, and exhibiting good adhesiveness to a metal without irradiation with an electron beam or γ-rays; and to provide the sheet comprising the adhesive composition, and a composite obtained by sticking the sheet on the metal.
The adhesive polymer composition contains at least 10-90 vol.% ethylene-(meth)acrylic acid copolymer and 0.1-75 vol.% fibrillated fiber. The sheet comprises the adhesive polymer composition. The method for forming the sheet involves passing the composition through the space between one or more pairs of pressure rolls having temperatures regulated so as not to be lower than the Vicat softening temperature of the polymer composition, defined by JIS K6760. The composite is obtained by tacking the sheet, and heating the tacked sheet to a temperature not lower than the Vicat softening temperature of the sheet.
