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

日、アルミニウム素材価格の高騰によりその製造
費用も比較的高価となり、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. However, due to the rise in the price of aluminum materials, the production costs are relatively high, and problems such as unsuitability for some types of packaging have been raised.

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.

の奏効する効果を要約して示せば次のとおりであ
る。 The lid material of the present invention shown in FIG. 1 is coated with a heat-resistant resin by coating one side of a polypropylene film 1 with an aluminum vacuum-deposited layer 5 and a heat-resistant resin-containing lacquer on the layer by printing or other means. It has a coating 2 and a hot-melt adhesive layer 4 such as a so-called hot-melt adhesive whose main components are ethylene/vinyl acetate copolymer and wax on the other side. It is shown 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は極めて薄く且つア
ルミニウム真空蒸着層５の高熱伝導性により高
速且つ高効率熱封緘が可能である。(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. High thermal conductivity allows for fast and highly efficient heat sealing.
(3) 該フイルム１上に所望の印刷３を施してもよ

金属光沢性に優れた蒸着層５と塗工被膜２との
中間に位置するためより一層鮮映な浮出し様と
なり、独特の美観が提供される。(3) A desired print 3 may be applied on the film 1, and in this case, the print 3 is located between the vapor deposited layer 5, which has better metallic luster than aluminum foil, and the coating film 2, so that it is more The embossed appearance becomes even more vivid, providing a unique aesthetic appearance.
(4) 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。(4) 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.
