摘要:
A multilayer structure having a layer of an adhesive resin composition (A) and a layer of another resin (B), wherein the adhesive resin composition (A) includes a thermoplastic resin (a1) containing functional groups of at least one kind selected from the group consisting of a boronic acid group and boron-containing groups capable of being converted into a boronic acid group in the presence of water, and a polyolefin (a2) which does not contain the functional groups, the blending weight ratio (a1/a2) of the thermoplastic resin (a1) to the polyolefin (a2) is 1/99 to 15/85, and particles of the thermoplastic resin (a1) are dispersed with an average particle diameter of 0.1 to 1.2 μm in a matrix of the polyolefin (a2). Consequently, a multilayer structures having satisfactory interlayer adhesion strength can be provided even if the content of the resin having a special functional group in the adhesive resin composition layer is reduced.
