Description

Bag(s) Technical Field The present invention relates to a bag comprising a water-soluble film, a laminate comprising a water-soluble film and a support, and a coating agent for forming a water-soluble film. Background There is known a method of packaging a liquid drug in a water-soluble film to form a bag, putting the bag into water at the time of use, and dissolving the content together with the film in water for use (patent document 1). Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2019-081901 Disclosure of Invention Problems to be solved by the invention For example, when the bag is filled with a detergent for washing or the like and used, if the solubility of the bag in cold water is low, it takes time for the bag to dissolve, and thus there is a possibility that dissolution residue may occur in laundry. In addition, in particular, when polysaccharides are contained, there is a case where the solubility in cold water is low. In addition, in the bag containing the contents, mechanical strength is also required in order not to be broken or the like at the time of transportation. Accordingly, an object of the present invention is to provide a bag comprising a water-soluble film excellent in solubility at low temperatures and mechanical strength, a laminate comprising a water-soluble film and a support, and a coating agent for forming a water-soluble film. Means for solving the problems The present inventors have conducted a detailed study in order to solve the above problems, and as a result, have found that the above problems can be solved, and have completed the present invention. That is, the present invention includes the following preferred embodiments.
