Description of the Related Art Examples of a package for a quality preservative include packages of a deoxidizer, a carbon dioxide gas absorbent, an ethylene absorbent, a desiccant, a rust preventive, and the like. Above all, oxygen scavenger packages have recently been widely used mainly for food products. However, there is a wide variety of foods subject to quality preservation, and conventional oxygen-absorbing packaging using a breathable packaging material causes stains and
There were many foods and beverages that were difficult to apply due to the occurrence of rust and the like.

It had been. But,
When this oxygen absorber is applied to humid foods and beverages, the packaging material is inferior in water resistance, so that the packaging bag of the oxygen absorber is damaged due to moisture, or the contents permeate through the holes of the perforated polyethylene film. This is not preferable in terms of food safety and hygiene, and furthermore, the rate of oxygen absorption is reduced due to water wetting, and the quality retention ability may not be sufficiently exhibited.

Packaging materials are disclosed. Also, JP-A-56-124440 or JP-A-5-124440
Japanese Patent Application Laid-Open No. 6-124441 discloses a packaging material using a plastic film also having a hole in the surface. However, since the surface of the packaging material is a plastic film, the surface of the packaging material is higher in water resistance than paper, but is provided with a large number of through holes for providing air permeability, so that a humid food, that is, a food having a high moisture content. When it comes in contact with, the packaging material becomes wet and the contents seep out, causing a problem of safety and hygiene, and has a low strength. In addition, there are drawbacks such as deformation of the holes and change in air permeability due to the effect of the adhesive due to thermal bonding or use of an adhesive during the production of the packaging material. In addition, when applied to humid foods, the plastic film and paper on the surface may peel off, making it impossible to use them as packaging materials such as oxygen absorbers. In any case, it is a common practice to ensure oxygen permeability by piercing pores in a plastic film with a needle or the like. And the quality preserving agent such as the oxygen scavenger gets wet to stop the oxygen absorption or leak the contents.

When a film such as polybutadiene) is used as a packaging material for a quality preservative such as an oxygen scavenger package, the oxygen permeability required for obtaining a practically sufficient oxygen absorption rate, although having excellent liquid resistance, It was impossible to secure. Furthermore, as an example of a cap-type oxygen absorber for liquids,

Ingenuity is required. As one of the pretreatments, it is also effective to carry out a pretreatment step in which fine scars are mechanically formed with a file-like roll before discharging. Alternatively, it is also effective to subject the film to acid treatment to form a polar group on the film surface, and then perform discharge perforation. Furthermore, in order to provide a local discharge portion on the dielectric roll, it is also possible to disperse missing portions in the coated dielectric layer, or to use a dielectric layer in which a conductive material is dispersed to reduce the perforation density and the perforation depth. It is effective for adjustment.

The processing power needs to be adjusted depending on the thickness, material, passing speed, and the like of the packaging material to be perforated, but is, for example, in the range of 5 to 200 W / m 2 / min. The drilling direction is such that the remaining film portion side is in contact with the dielectric roll.

On the other hand, in Comparative Example 2, the liquid resistance of the oxygen scavenger package was insufficient, and rust and stains were generated.
It is presumed that the liquid in the bag permeated into the package and oxygen absorption stopped, and oxygen intruding from outside the bag could not be completely removed, and the oxygen concentration in the bag was rising. Comparative Example 3
However, the oxygen permeability was so small that a sufficient quality maintaining effect could not be obtained.

Excellent liquid resistance quality that solves the problems of the conventional quality preservative package by adopting a structure in which the quality preservative is packaged and sealed by using the water-resistant packaging material as the whole or a part of the package. A retainer package is obtained. That is, by perforating the non-penetrated microporous, sufficient air permeability as a quality preservative package is secured, and at the same time, extremely excellent liquid resistance is obtained by leaving a non-penetrated membrane portion, and desired air permeability is obtained. It has a sufficient quality maintenance function and exhibits extremely excellent liquid resistance in terms of liquid impermeability and liquid strength. In particular,
When applied to a liquid article or a highly watery article, the liquid does not wet the quality preservative or exudes the quality preservative, and is excellent in function and safety and health. Therefore, it is suitable for sequestering a quality preservative or a quality preservative in which leakage of contents is a problem for a high-moisture article.
It can be effectively used not only in the field of foods such as fruits and vegetables, but also in a wide range of fields such as metal parts and pharmaceuticals.
