Title:
THERMOPLASTIC RESIN SHEET AND MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2015/056781
Kind Code:
A1
Abstract:
[Problem] To provide a food-use molded article that exhibits excellent antistatic properties and water repellency and maintains the inherent external appearance and mechanical properties of the molded article even in a deep-drawn section having a high drawing ratio during molding or even when molding is performed at a high temperature. [Solution] A laminate sheet is prepared having a multilayer configuration of two or more layers of two or more types, comprising a thermoplastic resin, a main layer made up of talc and a white pigment, and, on the opposite side, a skin layer comprising an antistatic resin composition containing at least one type of thermoplastic resin and an antistatic agent. By thermoforming a sheet comprising the resin composition, it is possible to obtain a molded article exhibiting water repellency and excellent antistatic properties effective for preventing contamination and soup powder adhesion. The polymeric antistatic agent has a fatty acid ester sulfonate as the main component, the surface resistivity is preferably 1013Ω/□ or less, and the water droplet contact angle is 90º or greater. The laminate sheet is preferably manufactured by co-extrusion.
