WIPO Patent Application WO/2023/149476
Kind Code:
A1
Abstract:
The present invention involves a multilayer sheet for food having a paper base material and a resin layer provided on one or both sides of the paper base material, the resin layer containing polylactic acid. In a temperature–displacement curve, from −20°C to the temperature at completion of indenter penetration, of the resin layer obtained by thermomechanical analysis according to JIS K 7196 (2012), the slope of the curve at each temperature is determined, and the number of peaks of a temperature–slope curve obtained by plotting the slope against temperature is two or less. The present invention further involves a manufacturing method for the multilayer sheet for food, and a packaging material for food and a container for food that uses the multilayer sheet for food.
