<P>PROBLEM TO BE SOLVED: To provide a paper container for liquid which is excellent in processability, rigidity and heat-resistance. <P>SOLUTION: The paper container for liquid is composed of a laminate having at least one resin layer including a mixture of a high-density polyethylene (D) and a high-pressure method low-density polyethylene (E). The resin layer satisfies the following requirements (A) to (C): (A) Each of vertical and lateral 2%-tensile elastic modulu is 250 MPa or more; (B) the ratio of the lateral 2%-tensile elastic modulus to the vertical 2%-tensile elastic modulus is 0.8 or more and 1.4 or less; and (C) at least one of peaks of an endothermic curve obtained in temperature rise measurement by a differential scanning calorimeter satisfies 125°C or higher. <P>COPYRIGHT: (C)2012,JPO&INPIT |
