FOOD PACKING MATERIAL HAVING HYDROPHOBICITY, MANUFACTURING METHOD AND MOLD THEREOF

摘要

PURPOSE: A hydrophobic food packaging material, a method for manufacturing the same, and a mold for the same are provided to omit a process for implementing hydrophobicity, such as photolithography. CONSTITUTION: A method for manufacturing a hydrophobic food packaging material comprises: a step of preparing a mold with a plurality of grooves; and a step of pressurizing the mold to a food packaging material(100) and forming a plurality of columns(110) corresponding to the grooves. The step of preparing the grooved mold comprises a step of preparing a first metal layer; a step of laminating a photoresist film on the upper portion of the first metal layer; a step of patterning the photoresist film and forming a plurality of photoresist patterns with a predetermined interval; and a step of laminating a second metal layer on the first metal layer.
