摘要：Problem to be solved: to reduce blinking such as blinking when forming animage on a packaging material by laser marking. A method of manufacturing a packagingbody including an image forming step including a substrate layer and a laser coloringlayer containing a component irreversibly colored by a laser and applying an image to a

packaging material comprising a laser forming layer for forming an image on a packagingmaterial, and a material layer of the packaging material and laser coloring A method ofmanufacturing a packaging body having an adhesion improving layer between the layersand an average output of the laser beam of 15 W or less and a spot diameter of 0.08 mmor more.AndLaser is applied to a packaging material with a substrate coloring layer and alaser coloring layer containing an irreversibly colorant component.A method ofmanufacturing a packaging body including an image forming process for forming animage on a packaging material;The laser coloring layer is formed by an ink compositionfor laser marking including a crosslinking agent.Average laser beam output below 15WAndThe spot diameter is 0.08 mm or more.Manufacturing method of packagingbody.Diagram
