Hot melt adhesive agent for container with straw
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).
1. A hot melt adhesive agent for a container with a straw consisting of:
(A) an amorphous poly-α-olefin selected from the group consisting of polypropylene homopolymer, polypropylene-polyethylene-1-butene copolymer, polypropylene-1-butene copolymer, and mixtures thereof;
(B) a metallocene polymer selected from the group consisting of polypropylene homopolymer, polypropylene-octene copolymer, polypropylene-polyethylene, and mixtures thereof;
(C) a tackifying resin;
(D) a wax
(E) an oil; and
(F) optionally an additive.
2. A container with a straw, to which a straw is retained by the hot melt adhesive agent according to claim 1 .
3. The hot melt adhesive agent for the container with the straw according to claim 1 , wherein
the amorphous poly-α-olefin (A) is present from 30 to 50, parts by weight;
the metallocene polymer (B) is present from 20 to 40 parts by weight;
the tackifying resin (C) is present from 5 to 30 parts by weight; and
wherein the parts by weight is based on 100 parts by weight of a total weight of (A) to (E).
4. A container with a straw, to which a straw is retained by the hot melt adhesive agent according to claim 1 .
