Abstract
The invention provides a hot melt adhesive comprising a polymer mixture of an ethylene vinyl acetate polymer with low vinyl acetate content and a functionalized metallocene catalyzed polyethylene copolymer. The hot melt adhesive has wide service temperature ranges for bonding cellulosic substrates together. The adhesive is well suited for case, tray, carton and bag sealing applications.
Claims16
A hot melt adhesive composition comprising:
- (A) an ethylene vinyl acetate polymer, wherein the vinyl acetate content is less than 25%;
- (B) a functionalized ethylene-alpha-olefin copolymer;
- (C) a wax;
- and
- (D) a tackifier,
- wherein the adhesive has an improved low temperature flexibility and heat resistance over an adhesive without the functionalized ethylene-alpha-olefin copolymer.
