Description

Water-soluble film Technical Field The present invention relates to a water-soluble film containing polysaccharides, a bag comprising the water-soluble film, a laminate comprising the water-soluble film and a support, and a coating agent for forming the water-soluble film. Background Conventionally, water-soluble films have been widely used for bags and the like for containing cleaning agents, fragrances, medicines and the like, and the films have been required to be enlarged for their simplicity. As the water-soluble film, for example, a water-soluble film containing polysaccharides is known (for example, patent document 1). Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 60-58044 Disclosure of Invention Problems to be solved by the invention However, the mechanical strength of the water-soluble film as in patent document 1 is insufficient, and for example, when the film is used in the form of a bag, breakage or the like may occur during transportation. Accordingly, an object of the present invention is to provide a water-soluble film having excellent mechanical strength, a bag comprising the water-soluble film, a laminate comprising the water-soluble film and a support, and a coating agent for forming the water-soluble film.
