Is recognized. As its characteristics, it has a unique resin odor, has no barrier property,
Having an affinity for oily components and affecting packaging contents,
Additives, especially phenolic antioxidants, may adversely affect the package contents. For example, in food packaging, the polyodor or acetic acid odor of the sealant layer may be transferred to the food, the oily food may be compatible with the sealant to affect the taste, and the aroma of the food may be adsorbed to the sealant layer. Even in the case of pharmaceutical packaging, there is a possibility that the drug components may be adsorbed by the sealant layer and affect the drug efficacy. Also in the packaging of clothes, the phenolic antioxidant contained in the sealant, especially the monophenolic compound benzenehydroxytoluene (BH
In some cases, the yellowing substance of T) diffuses and transfers to clothing, and further reacts with nitrogen oxide gas in the atmosphere that has penetrated into the packaging bag to generate a yellowing substance, which causes a yellowing accident. That is, it is necessary to pay sufficient attention to the selection of a sealant for food packaging with oily or aromatic substances, pharmaceutical packaging such as poultices, or clothing for light-colored clothing that easily yellows.

ｒである。[Means for Solving the Problems] A sealant for a composite film of a packaging bag, which is an alternative to a polyolefin sealant, has oil resistance and barrier properties, and has excellent oxidation resistance and does not require a phenolic antioxidant. As a result of earnest studies, it was found that unstretched polyester is the most suitable. The non-stretched polyester sealant can be easily heat-sealed, and its sealing strength is not as high as that of the polyolefin sealant, but it shows sufficient sealing strength for light-weight packaging applications such as snacks, snacks, and clothing. The melting point of polyester is considerably higher than that of polyolefin. For example, the melting point of polyethylene terephthalate is 274 ° C, whereas the melting point of high-density polyethylene is 127 ° C. However, unstretched polyethylene terephthalate has the property that it can be heat-sealed even at a temperature considerably lower than the melting point, and a packaging bag that can be made into a bag and can be practically used can be obtained. The barrier property of polyester is remarkably superior to that of polyolefin, and it is possible to prevent adsorption, diffusion and permeation of oxygen, nitric oxide, perfume, happen component, BHT and the like. For example, unstretched polyethylene terephthalate with a thickness of 30μ is at 25 ° C.

る。The sealant of the present invention is an unstretched polyester, and the polyester is a polyester containing 80 mol% or more of ethylene terephthalate units, and polyethylene terephthalate is particularly preferable. The sealant may contain additives such as slip agents and antistatic agents, but phenolic antioxidants are not preferred for clothing packaging applications. The polyester sealant layer of the composite film is formed by an extrusion lamination method in which a polyester resin is directly extruded and laminated with a non-stretched polyester, or a dry lamination method in which a non-stretched polyester film formed in advance is laminated with an adhesive.

合フィルムの包装袋が最も好ましい。The composition of the composite film of the present invention is not particularly limited except that the sealant layer is unstretched polyester, and is selected according to the intended use. For example, vinylidene chloride-coated biaxially oriented polypropylene is preferred because it requires moisture resistance and oxygen barrier properties for snack confectionery packaging, and aluminum vapor-deposited biaxially oriented polyester or the like is used for packaging of snapping agents to prevent drug penetration. preferable. It is necessary for clothing packaging centering on white clothing that easily causes yellowing accidents to have a nitrogen oxide gas barrier property of the packaging material and no phenolic compounds contained in the packaging material, especially no yellowing substances such as benzenehydroxytoluene. Yes,
From the viewpoint of cost performance and recycling, a composite film of biaxially stretched polyester and unstretched polyester is preferable. Furthermore, from the viewpoint of packaging design, one component of the composite film is a non-woven fabric, and especially the outermost one is a non-woven fabric,
The packaging bag in which the sealant layer is unstretched polyester is more preferable in appearance and texture. Furthermore, a packaging bag of a composite film comprising a polyester nonwoven fabric and a non-stretched polyester sealant layer, which has the most suitable constitution in recycling the packaging material and is excellent in cost performance and recyclability, is most preferable.
