Title:
HIGH GLOSS THERMOFORMED ARTICLE AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2011/031443
Kind Code:
A3
Abstract:
The present disclosure is directed to a thermoforming process and thermoformed articles produced therefrom. The thermoforming process includes heating a structure with a gloss layer composed of a propylene-based polymer having a melt flow rate from about 0.1 g/10 min to about 1.5 g/10 min, and producing a thermoformed article wherein the gloss layer has a post-thermoformed Gardner gloss value within 25% of the pre-thermoformed Gardner gloss value for the gloss layer. The thermoformed article may have a gloss layer with a post-thermoformed Gardner gloss value greater than or equal to about 60.
