本発明は、ハム、ソーセージ等の食品包装用フィルムで
、印刷層を有し、しかも防曇性を有する食品包装用防曇
フィルムに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an anti-fog film for food packaging such as ham and sausages, which has a printed layer and has anti-fog properties.
一般にハム、ソーセージ等の含水性食品を包装用フィル
ムは、食品または付着した水分が、包装した包装フィル
ムの内面に水滴が付着し、曇りが生じ食品が見えない等
外観が悪い現象が生じていた。In general, with films for packaging water-containing foods such as hams and sausages, water droplets from the food or adhering moisture adhere to the inner surface of the packaging film, causing cloudiness and poor appearance, such as the food being difficult to see. .
これらの食品は、一般にポリエチレン等のポリオレフィ
ンを内面に用いた包装フィルムを用いているので、温度
、湿度の変化により包装フィルムの内面に水滴が付着し
、曇りが生じていた。Since these foods generally use a packaging film that uses polyolefin such as polyethylene on the inside surface, water droplets adhere to the inside surface of the packaging film due to changes in temperature and humidity, causing cloudiness.
このように曇りが生じると不透明となり、食品が見えな
い状態となってしまい不都合が生じていた。When cloudiness occurs in this way, it becomes opaque and the food cannot be seen, causing inconvenience.
この問題を解決するため、内面に非イオン性の界面活性
剤を樹脂に混練またはコーティングし、水滴が生じるこ
とな（、均一にぬらすことにより、不透明になることを
防止していた。In order to solve this problem, a nonionic surfactant was kneaded or coated with the resin on the inner surface to prevent water droplets from forming (and by uniformly wetting it, preventing it from becoming opaque).
また、食品を包装する包装フィルムには、印刷層を設け

た。In addition, packaging films for food packaging are generally provided with a printed layer, and if the printed layer is provided on the surface of the base material, there is a risk of it peeling off due to rubbing, etc., so a printed layer is provided on the back side and an adhesive layer is added. It was used as a laminate structure in which a polyolefin layer kneaded with a nonionic surfactant was provided between the layers.
ところが使用中にポリオレフィン層の非イオン性界面活

。However, during use, the nonionic surfactant in the polyolefin layer bleeds out, resulting in a decrease in the adhesiveness between the printed layer of the base material and the polyolefin layer.

層へ移行するのを防止することが提案されている。In order to solve this phenomenon, in Japanese Patent Publication No. 60-34460, a nonionic surfactant is not kneaded between the printing layer of the back-printed base film and the polyolefin layer kneaded with a nonionic surfactant. It has been proposed that by interposing a polyolefin layer, even if the nonionic surfactant bleeds out, the interposed polyolefin layer prevents it from transferring to the adhesive layer.

た。In order to prevent a decrease in adhesive strength due to surfactant bleed-out, which is a problem when a polyolefin layer kneaded with a surfactant is provided on the inner surface of a base film having a printed layer, conventionally, There were various problems, such as the need to provide a polyolefin layer without kneading a surfactant between them, the need to specify the combination of resins for each layer, and the need to specifically select the ink used for the printing layer.
本発明の目的は、このような従来の問題を解決し、従来

着強度の低下が防止できた。Furthermore, even if the base film and the polyolefin layer are made of different types of resin, they can be laminated by providing an adhesive resin layer made of a resin with good adhesive properties between them, so that they can be laminated in the same way. It was possible to prevent a decrease in adhesive strength due to bleed-out.
