摘要:
Coated composite materials and methods for their manufacture are described. In particular, embodiments of the present invention include a substrate material coated on at least a portion with a polymer blend comprising from about 50 to about 95 wt % of a propylene-based copolymer comprising propylene and from about 3 to about 40 wt % ethylene-derived units and from about 5 to about 50 wt % of a hydrocarbon resin. The propylene-based copolymer has a melting temperature less than about 110° C., a heat of fusion less than about 75 J/g, and a triad tacticity greater than 75%. The coating compositions are suitable for hot fill applications, soft to the touch and have a low coefficient of friction, low haze, and are able to retain textural design features. Methods for forming such coated composite materials are also provided.
