して、包材の材質、構成等をかえて対応しているか、完
全な脱酸素剤用包材とはなっていない。The problem with food preservation technology using oxygen absorbers is that oxygen absorbers are used for a variety of foods such as dry foods, high moisture foods, acidic foods, oil-processed foods, and alcohol-containing foods.
Moisture contained in the oxygen scavenger composition may transfer to dry foods, impairing oxygen scavenging performance, or moisture from high-moisture foods may transfer to the oxygen scavenger composition, causing stains on the surface of the packaging material. It may damage the appearance, it may seep into the food's oil or packaging material, it may impair the air permeability of the packaging material, and it may impair its oxygen scavenging performance. Due to these drawbacks, depending on the situation in which the oxygen absorber is used, the material, structure, etc. of the packaging material must be changed, or the packaging material for the oxygen absorber is not perfect.
近年は、脱酸素剤の適用分野が多岐にわたり、使用条件
が過酷となる傾向にあるため、微多孔膜などを用いた耐
久性の優れた包装材料が多用されている。In recent years, oxygen scavengers have been applied to a wide variety of fields, and the conditions for use have become increasingly harsh, so highly durable packaging materials using microporous membranes and the like have come into widespread use.

付与する事は困難である。On the other hand, for film lamination, it is common to thermally laminate a low melting point sealant film made of polyethylene, polyethylene vinyl acetate copolymer, ionomer resin, etc. as an adhesive layer, but this method is adopted in the present invention. , the low melting point film melts during thermal lamination,
The pores of the low-melting-point sealant film become clogged, and the air permeability of the film having micropores decreases, and it is difficult to provide stable air permeability.
又、透気度を確保するために、低温のラミネート条件を
採用すると十分なラミネート強度を得る事かできない。Furthermore, if low temperature lamination conditions are used to ensure air permeability, sufficient lamination strength cannot be obtained.

Water- and oil-resistant treated paper is often heat-laminated with a low-melting point sealant film made of polyethylene, polyethylene vinyl acetate copolymer, ionomer resin, etc. When melted, the small diameter pores of the perforated plastic film become clogged and the air permeability decreases, making it difficult to maintain stable air permeability. There are many unsatisfactory points.

般的であるか、これらにおいては、包装材料のラミネー
ト加工条件の設定が難しく、高価格であるだけでなく、
透気度を自由に調整する事は不可能であった。Conventional oxygen absorber packaging using a microporous membrane or nonwoven fabric generally uses a packaging material in which a microporous membrane or nonwoven fabric is laminated with a perforated low melting point sealant film. In these cases, it is difficult to set laminating processing conditions for packaging materials, and it is not only expensive, but also
It was impossible to freely adjust the air permeability.

低温のラミネート条件を採用すると十分なラミネート強
度を得る事ができない。In other words, if a perforated low-melting point sealant film is laminated onto a film (C) having micropores, the sealant film will melt and the pores of the low-melting point sealant film will be blocked, resulting in a decrease in air permeability and a stable permeability. It is difficult to impart temperament. In addition, to ensure air permeability,
If low temperature lamination conditions are used, sufficient lamination strength cannot be obtained.

ネートしてないので透気性を低下させる事もない。In the present invention, the sealing layer is a resin layer in which (A) is formed with a resin having a softening point equal to or lower than that of (A) in the form of many streaks or fine meshes, and (C) is used alone. ing. In addition, (C) is only reinforced by laminating a reinforcing material as necessary, and is not laminated with a low melting point sealant film, so there is no reduction in air permeability.

) The resin is formed regularly in only a part of (A) because the sealing layer is a plastic film made by forming many streaks or fine meshes of resin with a softening point equal to or lower than that of (A). Therefore, compared to conventional plastic laminated films made by extrusion lamination of low-melting point resins, the plastic film (A) is reinforced without impairing its properties, especially its flexibility, resulting in better bag-making properties. Sufficient adhesive strength can be obtained.
