| 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 HO0C, 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. |
