のに適した積層フィルムに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a laminated film, particularly for use in lids and bags for food packaging containers such as microwave-heated foods, and non-food products such as insect repellents and aromatics. The present invention relates to a laminated film suitable for use as a lid material for a container, a bag body, etc.
従来から、電子レンジ加熱食品として各種容器や袋体で

いた。BACKGROUND ART Conventionally, microwave heated foods packaged with retort sterilized cooked rice and the like in various containers and bags have been commercially available. When heating such microwave-heated foods in the microwave, in order to prevent them from bursting due to an increase in internal pressure, for example, in the case of tray-type containers, part of the lid material may be peeled off, or a portion of the lid material may be peeled off several times using a toothpick. Ventilation and water permeability were provided by making holes in the locations or by peeling off the entire surface of the lid material and covering it with a fitting lid.
また、通気１通水性を要する包装の例として、袋体を用

ができる。このティーバッグには、抽出内袋として不織
布やナイロンネットが用いられ、外袋には紙袋又はアル
ミ箔をバリヤー層とした防湿袋が使用されている。Further, as an example of packaging that requires ventilation and water permeability, a tea bag can be mentioned as a food product using a bag. In this tea bag, a non-woven fabric or nylon net is used as the inner bag, and a moisture-proof bag with a paper bag or aluminum foil as a barrier layer is used as the outer bag.
さらに非食品としては、防虫剤を袋体に包装したものが
ある。このものは、防虫剤を含有させた錠剤を不織布等
の透気性のある包材で個別包装し、これを複数個まとめ
てバリア性の包材で集合包装したものである。Furthermore, as non-food items, there are insect repellents packaged in bags. In this product, tablets containing an insect repellent are individually packaged with air-permeable packaging materials such as non-woven fabrics, and then a plurality of tablets are collectively packaged with a barrier packaging material.
しかしながら、電子レンジ食品を加熱する際に、その蓋
材を一部剥離すると、この部分からの水分蒸散が多くな

要であり、さらに孔の開は方が不充分であると調理中に
容器内の圧力が上昇し、破裂する危険性がある。また嵌
合蓋を使用するものは、包材コストの面で問題がある。In addition, tools are required to make holes in the lid or bag body, and if the holes are not made sufficiently, the pressure inside the container will increase during cooking and there is a risk of it bursting. . Moreover, those using a fitting lid have a problem in terms of packaging cost.
一方、ティーバッグや防虫剤等の袋体として外袋に紙を
使用したものは、保香性、防湿性に劣り、またアルミ箔
構成袋を使用したものは、コスト的にも又包装工程的に
も負担が大きい。On the other hand, tea bags, insect repellents, etc. that use paper for the outer bag have poor fragrance retention and moisture resistance, and those that use aluminum foil bags are expensive and difficult to package. It is also a heavy burden.
そこで本発明は、上記各種食品、非食品等の包材、特に
容器の蓋材として好適な積層フィルムを提供することを
目的としている。Therefore, an object of the present invention is to provide a laminated film suitable as a packaging material for the above-mentioned various foods, non-foods, etc., particularly as a lid material for containers.
