Manufacturing method of packing film using environment-friendly ink for gravure print and environment-friendly packing film manufactured by the same

摘要

The present invention comprises the steps of: forming a printing layer (2) on one surface of the first film (1) by performing a gravure printing process using an eco-friendly ink for gravure printing; forming an adhesive layer (3) by applying an adhesive to the other side of the printed layer (2) and then drying; and laminating a second film (4) on the other side of the adhesive layer (3). As a method of manufacturing a packaging film using an eco-friendly ink for gravure printing, The eco-friendly ink for gravure printing is 10 to 30% by weight of a polyamide-based resin, 1 to 10% by weight of a nitrocellulose resin, 10 to 30% by weight of a pigment, 1 to 10% by weight of a wax, 1 to 10% by weight of a filler, and 30 to 70% by weight of a solvent % by weight; By using the solvent containing 20 to 60 parts by weight of isopropyl acetate and 1 to 20 parts by weight of cyclohexane based on 100 parts by weight of an alcohol-based solvent in which ethyl alcohol and propyl alcohol are mixed; It is eco-friendly because it does not use VOC regulated substances that have a harmful effect on the human body and the atmosphere, and high-quality prints can be obtained because of its fast drying speed and excellent color development, as well as excellent adhesion to the substrate and excellent print strength after drying. It relates to a method for manufacturing a packaging film using an eco-friendly ink for gravure printing and to an eco-friendly packaging film manufactured therefrom.
