HEAT-RESISTANT PAPER CONTAINER AND PROCESS FOR PREPARATION THEREOF

摘要

Disclosed is a heat-resistant paper container which comprises a bottomed seamless press-molded body comprising a laminate of a paper substrate (11) having an elongation of at least 1.5% in the longitudinal direction and an elongation of at least 4.5% in the lateral direction and a coating layer of a hiding pigment (12a + 12b) formed on both the surfaces of the paper substrate (11), wherein the amount coated of the hiding pigment is 1 to 50 g/m<2>, the binder in the coating layer is a thermosetting resin binder and the binder is present in the coating layer at a weight ratio RP satisfying the following condition: RP = k.OA.dR (1) wherein OA stands for the oil absorption (m l /100.g) of the hiding pigment, dA stands for the density (g/m l ) of the binder, and k is a number of from 0.005 to 0.2.
