The body was heat-sealed together with the bent side edge joints to form a lower transverse section, and a bottomed tubular body T was formed. The side portion of the bottomed tubular body T was swollen due to the stress of the packaging material. The depth H of the bottomed tubular body T at the time of molding was 90 mm, and the width W of the bottom of the bottomed tubular body T was 25 mm.

Next, 2.4 g of the oxygen scavenger composition was charged from the filling nozzle inserted inside the upper end opening of the bottomed tubular body T. The oxygen absorber composition used was

After the oxygen scavenger composition was charged, 1 cm above the charged portion of the oxygen scavenger composition was heated by a transverse seal bar together with both side edge seal portions bent in the same direction as the bottom seal portion. Sealed to the top,
An oxygen absorber package having a width of 25 mm and a length of 45 mm was manufactured. Depth H of bottomed tubular body T (90 mm) / Bottomed tubular body T
The width W (25 mm) of the bottom portion is 3.6, and the vertical distance L (90 + 7.5-45 + 7.10) between the upper end of the depth of the bottomed tubular body T and the upper end of the charged portion of the oxygen scavenger composition charged. 5 + 10 =
70 mm) / width W of bottomed tubular body T bottom (25 mm) =
2.8).

Simultaneously with the heat sealing of the bottom portion, both side edges in the longitudinal direction of the air-permeable film strip are heat-sealed to form a new bottomed tubular body T having the top portion as the bottom portion. The following oxygen-absorbing agent package was manufactured by adding the agent composition.

Thereafter, the above-mentioned unit operation is repeated to continuously produce a strip of the oxygen-absorbing agent package.
A continuous band of 000 oxygen absorber packages was spirally wound and packed to form one pack. The entire surface of the package of the manufactured oxygen scavenger package is 40 mm × on a petri dish.
Wipes with 50 mm gauze, heat-dissolves the fallen dust and gauze with hydrochloric acid, and determines the iron concentration in the solution by ICP-A.
It was quantified by ES (Inductively Coupled Plasma Atomic Emission Spectrometer 1200VR, manufactured by Seiko Instruments Inc.). As a result, the attached amount of iron powder per pack was 3 mg / pack, and the attached amount of iron powder per oxygen absorber package surface area was 0.27 mg.
/ M ² . In this oxygen scavenger package, iron rust was not adhered to the surface in appearance.

[Comparative Example 1] The depth H of the bottomed tubular body T at the time of molding was changed to 4 by changing the length of the heat seal portions on both side edges in the longitudinal direction.
Except for setting to 0 mm, the same operation as in Example 1 was performed to continuously manufacture the oxygen absorber package of the same size having a width of 25 mm and a length of 45 mm. Depth H of bottomed tubular body T (4
0 mm) / width W (25 mm) of the bottom of the bottomed cylindrical body T = 1.
6. The vertical length L (40 + 7.5−5) between the upper end of the depth of the bottomed tubular body T and the upper end of the charged portion of the oxygen absorber composition.
45 + 7.5 + 10 = 20 mm) / width W (25 mm) of the bottom of the bottomed tubular body T = 0.8.

The amount of iron powder adhering to the surface was determined in the same manner as in Example 1 for one pack (5,000) of the manufactured oxygen absorber package. As a result, it was 20 mg / pack, and the amount of iron powder attached per surface area of the oxygen scavenger package was:
1.77 mg / m ² . Some of the oxygen scavenger packages had iron rust adhered to the surface in appearance.

Example 2 One package of the oxygen scavenger package produced in Example 1, Chinese bun containing glycine (40 cm in diameter)
5 pieces of 18cm x 20cm KO with high gas barrier properties
Seal in N / PE packaging bag with air 300ml, 25 ℃
Saved below. During storage, 3 days after preparation, 10 days after, 30 days
After a day, oxygen concentration analysis by gas chromatography and appearance observation were performed. As a result, the oxygen concentration in the bag after 3 days was 0.1% by volume or less, and no abnormality such as discoloration and discoloration on the surface of the Chinese bun was observed up to 30 days later.

[Comparative Example 2] Except that one package of the oxygen scavenger prepared in Comparative Example 1 was used, the preparation was carried out in exactly the same manner as in Example 2, and the daily oxygen concentration analysis and the appearance of the Chinese bun were observed. . As a result, the oxygen concentration in the bag after 3 days was 0.1% by volume or less, but after 30 days, an abnormality such as discoloration and discoloration was observed on a part of the surface of the Chinese bun.

As can be seen from the above results, the depth H of the bottomed tubular body T is made larger than twice the width W of the bottomed tubular body T when continuously manufacturing the oxygen absorber package. And the vertical length L between the upper end of the depth of the bottomed tubular body T and the upper end of the charged oxygen-absorbing composition-filled portion is set to the width W of the bottomed tubular body T.
It can be seen that the amount of the oxygen scavenger composition adhering to the surface can be remarkably reduced by making it twice or more.
