PROBLEM TO BE SOLVED: To favorably transfer a food additive to the surface of a food with neither peels nor cracks of a transfer agent layer by applying a transfer packaging material made of a base material of a heat sealable synthetic resin for deep drawing packaging.SOLUTION: A transfer sheet for deep drawing packaging is configured by coating a base material of heat sealable synthetic resin for deep drawing packaging with a transfer agent layer, where the transfer agent layer contains a food additive and a coupling agent, the coupling agent being a mixture of at least two or more kinds selected from among a cellulose derivative, silicon dioxide, dietary fibers, and calcium carbonate. Using specific components such as the cellulose derivative, silicon dioxide, dietary fibers, etc. for the coupling agent in complex combination enables a smooth transfer of a transfer sheet to the surface of a food by suppressing peels or cracks from a base material of the transfer agent layer at a molding part even when an external load is applied on a packaging material by deep drawing molding.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 ヒートシール性合成樹脂の基材からなる転写包材を深絞り包装に適用して、転写剤層の剥離や割れがなく、食品添加剤を食品表面に良好に転写する。【解決手段】 深絞り包装用のヒートシール性合成樹脂の基材に転写剤層を塗工してなり、転写剤層は食品添加剤と結合剤を含有し、当該結合剤はセルロース誘導体、二酸化ケイ素、食物繊維、炭酸カルシウムより選ばれた少なくとも2種以上の混合物である深絞り包装用の転写シートである。セルロース誘導体、二酸化ケイ素、食物繊維等の特定成分を複合的に組み合わせて結合剤に用いることで、深絞り成形で包材に外部負荷がかかっても、成形部位での転写剤層の基材からの剥離や割れを抑制でき、食品表面に円滑に転写できる。【選択図】 図1
