本考案は、合成樹脂その他の材よりなる容器口
部に加熱、加圧により熱封緘される蓋材に関す

視ができないため包装の種類によつては使用に適
さない等の問題が提起されている。 Conventionally known heat-sealing lid materials mostly use aluminum foil as a heat-resistant base material, and in order to provide packing and heat-sealing properties to this, flexible resin films such as polyethylene films and heat-melt adhesives are used. These are made by sequentially laminating layers of reagents, but today, due to the soaring price of aluminum materials, their manufacturing costs are relatively high, and the contents of the container cannot be seen through, making them unsuitable for use depending on the type of packaging. Issues have been raised such as:
加えて、上記従来蓋材の積層構造に於いて、ポ

てのパツキング性は必ずしも良好とは言い難く、
特に、容器口部表面が微細な凹凸や不規則形状を
有する場合、その容器への熱封緘が不完全となり
使用に適さないものとなる。 In addition, in the laminated structure of the conventional lid material mentioned above, even though it is equipped with a flexible resin layer such as polyethylene film, the hardness and inelasticity of the aluminum foil, which is the heat-resistant base material, makes the lid material as a whole It is difficult to say that the packing properties of
In particular, if the surface of the container opening has minute irregularities or irregular shapes, the heat sealing of the container will be incomplete and the container will be unsuitable for use.

の提供を目的とするものである。 The present invention has excellent packing properties as a whole, can tightly heat-seal container openings that have minute irregularities and irregular shapes, and is easy to manufacture, allowing the contents of the package to be seen through if necessary. The purpose of this invention is to provide a lid material that is inexpensive.

３を有するものであり、その奏効する効果を要約
して示せば次のとおりである。 The lidding material of the present invention shown in FIG. 1 has a heat-resistant resin coating film 2 formed by coating a heat-resistant resin-containing lacquer on one side of a polyethylene or polypropylene film 1 by printing or other means, and the other side. It has a hot-melt adhesive layer 3 such as a so-called hot-melt adhesive mainly composed of ethylene/vinyl acetate copolymer and wax on its surface, and its effects can be summarized as follows. .
(1) アルミニウム箔等の硬質材を全く使用してい
ないので蓋材全体としてのパツキング性に優
れ、微細凹凸や不規則形状を有する容器口部を
も密着熱封緘し得る。(1) Since no hard materials such as aluminum foil are used, the lid material as a whole has excellent packing properties, and can tightly heat-seal container mouths that have minute irregularities or irregular shapes.
(2) 耐熱性樹脂塗工被膜２の有する充分な耐熱性
により、加熱加圧による熱封緘時の蓋材の熱変
形は生ぜず、該塗工被膜２は極めて薄いため熱
伝導性に富み高速熱封緘可能である。(2) Due to the sufficient heat resistance of the heat-resistant resin coating film 2, thermal deformation of the lid material does not occur during heat sealing due to heating and pressure, and since the coating film 2 is extremely thin, it has high thermal conductivity and can be used at high speeds. Can be heat sealed.
(3) 該塗工被膜２を介して包装内容物の透視が可
能である。(3) The contents of the package can be seen through the coating film 2.
(4) 該フイルム１上に所望の印刷３を施してもよ

り、独特の美観が提供される。(4) A desired print 3 may be applied on the film 1. In this case, since the print 3 is located between the transparent film 1 and the coating film 2, it becomes embossed and has a unique aesthetic appearance. provided.
(5) アルミニウム箔を使用せず且つ複雑な積層工
程なしに印刷等の単純塗布工程のみによつて製
造され得るため、その製造コストは著しく低廉
なものとなる。(5) Since it can be manufactured only by a simple coating process such as printing without using aluminum foil and without a complicated lamination process, the manufacturing cost is extremely low.
