損われるという欠点を有している。 Packaging materials with vapor-deposited aluminum layers in a multilayer stack are used as packaging materials that are molded materials for obtaining containers with excellent gas permeation resistance.Liquid containers obtained from this type of packaging materials When a highly acidic liquid such as fruit wine or vinegar is filled, the vapor-deposited aluminum layer in the constituent material of the container is attacked, and peeling from this area can occur, especially when the spout formed on the container is cut. It tends to occur on surfaces, and has the disadvantage that the laminated structure of the container peels off, impairing the airtightness of the container.

ない。 In the illustrated embodiment, the packaging material 1 of the present invention includes an aluminum vapor-deposited film 4, a lacquer resin layer 6, an epoxy-phosphoric acid synthetic resin layer 5, a urethane adhesive layer 7, and a synthetic resin layer having thermal adhesive properties. 8, the packaging material of the present invention has a multi-layered laminated structure consisting of a layered structure as in the above-described illustrated embodiment in the multi-layered structure constituting the packaging material. Therefore, in the case of the simplest one, it has a multi-layer laminated structure with the layer structure shown in the illustrated embodiment, but if desired, the multi-layer laminated structure may further include another arbitrary layer. Even if it is added, it cannot be used in any way.

ツカー樹脂層５が形成されるのが良い。 Further, the lacquer resin layer 6 laminated between the vapor deposited aluminum layer 2 and the epoxy-phosphoric acid synthetic resin layer 5 has the above-mentioned effect that the epoxy-phosphoric acid synthetic resin layer 5 has.
This is to alleviate the effect of phosphoric acid on the aluminum constituting the lacquer resin layer 6. If this lacquer resin layer 6 were not present, the entire aluminum constituting the evaporated aluminum layer 2 would be passivated. Although a high degree of acid resistance is introduced into the layer 2, the disadvantage is that the gas permeability of the layer 2 is significantly impaired. However, on the other hand, the lacquer resin layer 5 laminated between the vapor-deposited aluminum layer 2 and the epoxy-phosphoric acid synthetic resin layer 5 is impermeable to the phosphoric acid component in the epoxy-phosphoric acid synthetic resin layer. If a thick synthetic resin layer is formed as shown, the effect of the epoxy-phosphoric acid synthetic resin layer 5 on the vapor deposited aluminum layer 2 will be incomplete.
It is necessary that the lacquer resin layer 5 has an appropriate permeability to the phosphoric acid component, and to satisfy this condition, the lacquer resin layer 5 is usually formed with a thickness of about 2 to 3 μm. good.

を奏する。 The packaging material of the present invention has the structure as described above, and includes two vapor-deposited aluminum layers in a multilayer laminated structure.
Only a part of the aluminum constituting the layer is passivated, and as a result, acid resistance is introduced into the vapor-deposited aluminum layer 2 without reducing the inherent gas permeability of the layer 2. Therefore, it is possible to obtain a container that is extremely suitable for storing foods and drinks with relatively high acidity, such as vinegar and fruit wine.
