Description

食品包裝用膜及帶彩箱的食品包裝用小卷膜
本發明是有關於一種食品包裝用膜及帶彩箱的食品包裝用小卷膜。
先前，食品包裝用膜於飯店、餐廳等中用作業務用膜，或於家庭中在食品保存時、烹飪時等廣泛使用。近年來，為了容易以目視辨認膜的碎片朝食品中的混入，提出有一種將熱塑性樹脂作為主成分，進而含有銅酞菁系著色劑等著色劑的食品包裝用膜(專利文獻1)。
另一方面，於食品包裝用膜中，為了防止食品中的水分以水滴的形式附著於膜上，通常添加防霧劑。

根據本發明者等人的研究，判明若將藍色著色劑與防霧劑一同使用，則存在藍色著色劑於膜中未均勻地分散，膜的著色變得不均勻的情況。
因此，本發明的目的在於提供一種藍色著色劑的分散性優異的食品包裝用膜及帶彩箱的食品包裝用小卷膜。

以膜總量基準計，膜可含有70質量%以上的選自由聚氯乙烯系樹脂、聚偏二氯乙烯系樹脂及聚烯烴系樹脂所組成的群組中的至少一種作為熱塑性樹脂。
另外，本發明提供一種帶彩箱的食品包裝用小卷膜，其包括所述食品包裝用膜、小卷有食品包裝用膜的芯材、以及收納有食品包裝用膜及芯材的彩箱，且於彩箱設置有用以切斷食品包裝用膜的刃部。
