Oxygen-absorbing pouch container

Abstract

The invention provides an oxygen-absorptive pouch which is so excellent in oxygen absorption as to absorb oxygen remaining in the pouch after sealing and thus attain excellent storage of contents and which is improved in the moldability of a resin containing an oxygen absorbent, the dispersion of an oxygen absorbent, the stability of oxygen absorption performance, the release or separation of an oxygen absorbent from a base resin, and the rigidity of sealed portions, though these characteristics become problematic in using an oxygen absorbent which is excellent in oxygen absorption but little compatible with a base resin. The invention relates to an oxygen-absorptive pouch constituted of a bag-shaped body, a pipe which is fit and inserted into the body, a spout having a bung hole connected to the pipe, and a removable cap attached to the bung hole, which pouch has on the inside face a layer made of a resin composition obtained by blending a base resin with at most 20% (based on the resin) of a particulate oxygen absorbent comprising at least 20% of particles of 1000 m or below in size.

Description

technical field [0001] The present invention relates to an oxygen-absorbing bag container. More specifically, the present invention relates to an oxygen-absorbing bag container that absorbs oxygen remaining in a sealed container to improve the preservability of contents in the container. Background technique [0002] As simple packaging containers that are light in weight, small in size, and not easy to break, soft bag-shaped containers called pouches are gradually being used, and they are used in general beverages such as fruit juices, mineral water, sports drinks, and beverages containing health foods, Packaging of alcoholic beverages, jelly and other gel-like food and beverages. [0003] Similar to other conventional packaging containers, in bag containers, since oxygen remains in the container in which contents such as food are packaged, the contents are also deteriorated and discolored due to oxidation. In order to remove oxygen, it is also conceivable to perform vacuu...

AI Technical Summary

Problems solved by technology

[0011] In order to solve the above-mentioned conventional problems, the present invention provides an oxygen-absorbing bag container, which has excellent oxygen absorbing performance and absorbs the residual oxygen in the sealed container, so that the storage property of the contents is good, and at the same time, it is improved. Moldability of resin containing oxygen absorber, dispersibility of oxygen absorber, stability of oxygen absorbing performance, oxygen absorption Peeling or separation of the agent from the base resin, reduction in rigidity of the sealing part, etc.
