The oxygen-absorbing package of the present invention is produced by packaging an oxygen-absorbing composition comprising, as an effective component, an iron powder containing a fine iron powder passing through a 200-mesh standard sieve in an amount of 5% by weight or less by an air-permeable packaging material using an automatic filling-packaging machine. By using the above oxygen-absorbing composition, the iron powder is prevented from being partially scattered to attach to the outer surface of the oxygen-absorbing package during the industrial packaging operation using the automatic filling-packaging machine of high productivity, thereby enabling to obtain an oxygen-absorbing package capable of preserving products for a long period of time without contamination and color change during the storage.

An oxygen absorbing multi-layer film having a smooth surface is provided. The multi-layer film includes an oxygen permeating resin layer, a deoxidizing resin layer containing a particulate absorbing composition, a smoothing layer and a gas barrier layer. The oxygen absorbing multi-layer film is produced by extruding a resin composition containing a particulate oxygen absorbing composition to form a deoxidizing resin layer on a surface of a polyolefin resin forming a smoothing layer as a substrate for lamination, laminating an oxygen-permeating resin layer to the upper surface of the deoxidizing resin layer and laminating a gas barrier material on a lower surface of the smoothing layer. The multi-layer film has no protrusions through the film surface and has excellent heat-sealing and handling properties.

[Object] To provide a powder supply device, a powder filling packaging machine and a method of manufacturing a powder package capable of high-speed operation while suppressing false operations.[Means to Attain the Object] A powder supply device includes: a member 1 including a plate portion having holes 2 formed to penetrate through the plate portion; a moving mechanism 18 that moves the member 1 in such a manner that top openings of the holes 2 move along a specific moving path; an opening/closing member 5 that makes bottom openings of the holes 2 in closed state and opened state as the member 1 moves; a powder filling unit 14 that fills a specific amount of powders 3 in each of the holes 2 within a predetermined section in the moving path; and a sensor 4 that is provided above a path within a section other than the predetermined section in the moving path and that continuously monitors the moving path on the plate portion.
摘要:
Provides a packaging method for aqueous liquid materials whereby a molded container in which an aqueous liquid material has been sealed can be packaged simply by sealing it within a packaging container of an oxygen-absorbent multilayer material provided with an oxygen layer, without the addition of moisture, and whereby oxygen present within the packaging container can be removed to maintain the aqueous liquid material in an oxygen-free state. The method involves sealing a polyolefin or vinyl chloride molded container in which an aqueous liquid material has been sealed within an outer packaging container comprising a packaging container of an oxygen-absorbent multilayer material provided with an oxygen-absorbent layer which contains an iron oxygen absorbent with high oxygen absorption capabilities consisting of iron powder coated with a metal halide, and an alkaline earth metal oxide.
