<p>PURPOSE: To impart an impact resistance by which cracks are not generated along a crease line (folding line) of a paper container even when an impact within a service range such as a dropping, etc., applied from the outside, after freezing a liquid content being contained in the paper container. CONSTITUTION: A liquid paper container 1 is constituted by forming a low density polyethylene layer 8 on front and rear both surfaces of a paper base material 2. For such a liquid paper container 1, a high density polyethylene layer 3 which is drawn uniaxially or biaxially is formed on the low density polyethylene layer 8 on at least one surface of the front and rear surfaces of the paper base material 2, and the low density polyethylene layer 8 is laminated on the top of the high density polyethylene layer 3 to constitute the liquid paper container 1.</p> |
