Description

  The present invention relates to a standing pouch.

From the viewpoint of resource saving, standing pouches are used for refill containers for shampoos, rinses, hair conditioners, and the like. Such a standing pouch is made of a resin film, is filled with contents, and is commercially available with a product name, a description of the contents, a pattern, etc. displayed on the surface.
As a conventional method of providing such a display, there is a method of directly printing on a resin film, a method of attaching a label on which a display is printed (Patent Document 1), and the like.
As a method of printing directly on a resin film, there is a method of performing gravure printing on a resin film. Gravure printing is necessary to manufacture a printing plate with a concave surface to which the printing ink is attached for each different display, but it is suitable for mass production of the same product because high-speed printing is possible. . In addition, since the color can be adjusted by the depth of the recess, it is possible to display designs with high designability such as patterns and photographs, and it is also possible to print the display over a wide area on the front and back of the standing pouch. is there.

  On the other hand, in the method of attaching the label on which the display is printed, it is necessary to enlarge the label itself when the display is provided over a wide area on the front or back of the standing pouch. However, for example, if the label is enlarged and the label is provided near the lower end of the standing pouch, when the standing pouch is dropped upright, wrinkles are formed below the label and the appearance of the product is easily impaired. In addition, it may be difficult to attach a large label to a standing pouch with high accuracy.
