METHOD FOR MANUFACTURING PERFORATED RESIN FILM USED FOR GARDEN STUFF FRESHNESS KEEPING CONTAINER, METHOD FOR MANUFACTURING GARDEN STUFF FRESHNESS KEEPING CONTAINER, AND SYSTEM FOR MANUFACTURING PERFORATED RESIN FILM USED FOR GARDEN STUFF FRESHNESS KEEPING CONTAINER

摘要

To provide a method capable of stably providing a bore in a film in a method for manufacturing a perforated resin film used for a garden stuff freshness keeping packaging bag (in particular, a manufacturing method including a printing process using inks and a boring process by lasers).SOLUTION: A method for manufacturing a perforated resin film includes a printing process for printing inks including an organic solvent in at least part of a resin film, and a boring process for providing a bore by irradiating the resin film with laser light from a laser light source. Under an environment where an organic solvent concentration Cin an air near a portion where the printing process is performed is controlled to be different from an organic solvent concentration Cin the air near a portion where the boring process is performed. Also a system performing such the method is provided.SELECTED DRAWING: Figure 1
