It has good heat sealability with the sealant layer of the top film, and the same or similar resin as the sealant layer is used, and as the outer layer,
The material may be appropriately selected in consideration of the purpose of use of the container, heat resistance, rigidity, etc., and for example, polypropylene, polyester, polystyrene, or a resin containing these with an inorganic filler may be used. The outer layer may be a single layer or a multilayer including a gas barrier resin layer.
容器の強度は外層では保てばよく、内層は内容
物の保護ができればよいので薄くすることができ
る。 The strength of the container can be maintained in the outer layer, while the inner layer can be made thinner as long as it can protect the contents.
多層容器の内層と外層は適度の接着性を有する
素材が組み合わされ、その層間接着力は通常剥離
強度1.5Kg／15mm以下（引張速度300mm／min）と
するのが好ましい。 The inner and outer layers of the multilayer container are made of materials with appropriate adhesion, and the interlayer adhesion is usually preferably 1.5 Kg/15 mm or less in peel strength (at a tensile speed of 300 mm/min).
多層容器の内層とトツプフイルムは、容器本体

みを入れないようにする。 A circumferential cut 7 is made on the opening side of the flange portion of the inner layer of the multilayer container. The incisions are usually made by a pressing mold with a circumferential blade, and it is sufficient that the inner layer can be easily cut when the lid is peeled off. Good too. Further, the notch may be made all around the circumference, or a portion may be left. If you are removing the top film with part of it still attached, make sure not to cut that part.

ジーピールが可能となる。 For example, in FIG. 1, the knob is lifted upward. Then, the inner layer and outer layer of the multilayer container peel off, and the inner layer peels off up to the notch. Then, only the top film is peeled off after reaching the notch. Therefore, even if the top film and the flange portion of the container body are firmly adhered to each other, easy peeling is possible.
