| description | To provide a thermoformed container that contains an ethylene-vinyl alcohol copolymer (EVOH), has a layer formed using a resin composition in which neck-in and die build-up in melt-forming are suppressed, and has high uniformity of gas barrier property and good appearance.SOLUTION: A thermoformed container has a layer (α) formed of a resin composition, wherein the resin composition contains EVOH (A) and crotonaldehyde (B1), and further contains at least one selected from the group consisting of 2,4-hexadienal (B2) and 2,4,6-octatrienal (B3).SELECTED DRAWING: Figure 1
【課題】エチレン－ビニルアルコール共重合体（ＥＶＯＨ）を含み、溶融成形の際のネックイン及びダイビルドアップが抑制された樹脂組成物を用いて形成された層を有し、ガスバリア性の均一性が高く且つ外観が良好な熱成形容器等の提供。【解決手段】樹脂組成物からなる層（α）を有し、上記樹脂組成物が、ＥＶＯＨ（Ａ）及びクロトンアルデヒド（Ｂ１）を含み、２，４－ヘキサジエナール（Ｂ２）及び２，４，６－オクタトリエナール（Ｂ３）からなる群より選ばれる少なくとも１種をさらに含む、熱成形容器。【選択図】図１ |
