As a result of extensive research into films, we found that a water-soluble film whose main components are cellulose and at least one selected from edible polysaccharides having sulfuric acid groups and carboxyl groups, and a water-soluble film containing cellulose as its main components, as well as edible polyhydric alcohol and edible wax. By impregnating and/or coating with at least one selected from 8 rI of edible natural trees, it is possible to create cold water-soluble or hot water-soluble films, and based on this knowledge, the present invention 90 That is, the present invention has a structure in which at least one selected from edible polysaccharides having a sulfate group and a carbosyl group, and cellulose having a crystalline form of cellulose II, which is regenerated from an aqueous alkali metal hydroxide solution. At least 10% of cellulose II or a homogeneous body of edible polysaccharide and cellulose II, which is a main constituent in the body, is present as a marine component or a continuum, and the solid content in the product is 50 to 95: 1ik
i%, and at least one selected from edible polysaccharides having sulfate groups and carbosyl groups, and a crystalline form of cellulose n regenerated from an aqueous alkali metal hydroxide solution. Cellulose is the main component in the structure, and its existence form is cellulose III or a homogeneous body of edible polysaccharide and cellulose II is present as a sea component or a continuum in an amount of at least 10%, and the solid content in the product is 50%. ~95.1iit% of the Mizumachi film contains at least one selected from edible polyhydric alcohols, edible waxes, and edible natural resins and/or
Or it is a film characterized by being coated.

て観察する場合光学顕微鏡写真を用いることができる。At least one selected from edible polysaccharides having sulfate groups and carboxyl groups and a structure containing cellulose as main constituents used in the present invention are described in detail in Japanese Patent Application No. 60-85.
No. 474, % Application No. 1986-94585, Special Application No. 1987-9
No. 8578 and Japanese Patent Application No. 61-92262. In other words, it is a structure whose main constituents are at least one type of edible polysaccharide having a sulfate group or a carboxyl group, and cellulose having a crystalline form of cellulose II regenerated from an aqueous alkali metal hydroxide solution. Contains at least 10% of sea ingredients as a continuum with seaweed or edible polysaccharides. Here, the sea component refers to a phase that is distributed in a manner that wraps around a certain phase when a cross section of a structure is examined using a transmission electron microscope or an optical microscope. Transmission electron micrographs are used for observation, but optical micrographs can be used when observing over a large area.
また、連続体とは、穿孔はあっても連続して分布してい

ても一つの相とみられる構成ｖ４−を総称して連続体と
称する。海成分または連続体が１０％以上存在すること
が必要な理由は、フィルムが形をとどめ、適切な機械的
強度を有するためであ°る。Furthermore, a continuum refers to a phase that is continuously distributed even if there are perforations. Furthermore, the configuration v4-, which is seen as one phase even if small spots are visible under a microscope, is collectively referred to as a continuum. The reason why the presence of 10% or more of the sea component or continuum is necessary is for the film to retain its shape and have adequate mechanical strength.

途の場合には、海成分筐たは連続体の比率は８０〜９０
％またはそれ以上が好ましい。Particular strength of the film is required. For example, in the case of casing applications, the ratio of sea component casing or continuum is 80 to 90.
