Benefits of technology

[0014]According to the present invention, it is possible to provide a packaging bag for an atmosphere conditioner, such as an oxygen absorbing agent and a desiccant, which can be manufactured at low cost and by a simplified manufacturing process without leakage of the atmosphere conditioner from a supply section of a packaging bag and which can be used under high temperature conditions. By using this package for atmosphere conditioner according to the present invention, it is possible to retain the freshness and quality of articles, such as foods and pharmaceutical products, without causing the articles to be contaminated.

Problems solved by technology

Such phenomenon is undesirable in terms of the appearance of the packaging bag, as well as in terms of potential outside leakage of the atmosphere conditioner which has entered the sealing part.

Abstract

The present invention provides a packaging bag that is free from leakage of atmosphere conditioner from its supply section, manufacturable at reduced cost and by simplified manufacturing processes, and useable under high temperature conditions. The packaging bag has an upper end portion serving as a supply section from which the atmosphere conditioner is supplied. The upper end portion is formed such that a position of an end portion of a front side of a packaging material and a position of an end portion of a back side of the packaging material are shifted from each other, and a relatively protruding end portion is folded and welded onto an outer surface of the other end portion.

Description

TECHNICAL FIELD[0001]The present application is based on JP Appl. No. 2015-201495 filed on Oct. 9, 2015, the content of which is incorporated herein.[0002]The present invention relates to a packaging bag containing an atmosphere conditioner, such as an oxygen absorbing agent and a desiccant.BACKGROUND ART[0003]An atmosphere conditioner, such as an oxygen absorbing agent and a desiccant, is normally stored in a rectangular packaging bag and used. This packaging bag is typically manufactured using a rotary, three-way seal bag manufacturing and filling apparatus. In this apparatus, a packaging material constituting a packaging bag is formed into a bag shape, a nozzle is inserted from the remaining opening side (supply side) of the bag, an atmosphere conditioner is supplied from the nozzle into the packaging bag, and the supply side is then welded to hermetically close the supply side to form the packaging bag.[0004]However, according to the above-mentioned method, the powdery atmospher...
