Abstract
To provide a hot melt adhesive agent which is excellent in adhesive properties to a substrate material such as paper and a polyolefin, is also excellent in adhesive properties from a low temperature (around 4° C.) to a high temperature (around 50° C.), has little viscosity change even when a long time elapses, and has tack that is not too high. Provided is a hot melt adhesive agent for a container with a straw comprising an amorphous poly-α-olefin (A) and a metallocene polymer (B).
