PACKAGING MATERIAL COMPOSED FOR OIL-RESISTANT PAPER AND PACKAGING CONTAINER COMPOSED OF OIL-RESISTANT PAPER

摘要

PROBLEM TO BE SOLVED: To provide a packaging material composed for an oil-resistant paper having excellent resistance to oil without using a fluororesin.

SOLUTION: The packaging material composed for the oil-resistant paper is obtained by at least laminating a paper substrate layer to an oil-resistant layer. The oil-resistant layer is obtained by coating and drying a water dispersion of a lactic acid resin containing a polylactic acid resin having a D-lactic acid content of 1.5-25 mol% and 1-30 mass% of a polyoxyethylene polyoxypropylene block copolymer-based surfactant based on the polylactic acid resin and having a number-average particle diameter of polylactic acid resin of≤0.5μm. An excellent oil-resistant layer is formed by coating and drying the water dispersion of the lactic acid resin a plurality of times even in the case of a paper substrate.
