Abstract: This invention provides a water-soluble sealing packaging material having excellent halogen resistance which can seal a medicament to be dispersed or dissolved in water which does not contain a substance potentially harmful to human health, can be used safely, does not deteriorate and maintains solubility in water even if a medicament, especially a medicament comprising chlorine-containing compound or bromine-containing compound, is sealed by the packaging material and stored for a long period of time. The water-soluble sealing packaging material comprises a packaging raw material that comprises 100 parts by weight of a polyvinyl alcohol resin and 0.1 to 100 parts by weight of at least one of inorganic compound selected from the group consisting of a carbonate, an oxide and a hydroxide which have a metal selected from IIa group metals and IIb metals, and a hydrotalcite compound.

Abstract: A chitosan coating solution safe for oral administration, a water resistant chitosan coating film with reduced content of residual organic acid, and a coated medical preparation having the coating film are described. The preparation method includes incorporating a glycerin fatty acid ester into an aqueous chitosan solution prepared through dissolution with a volatile organic acid. The chitosan coating film is obtained by drying and solidifying the solution through film coating. The organic acid used in the dissolution remains in the coating film only minutely and the film is water resistant. When the chitosan coating solution (containing a glycerin fatty acid ester, and prepared through dissolution with a volatile organic acid) is coated, a film is formed therewith, and the organic acid volatilizes simultaneously, producing a chitosan water resistant coating film. Forming a known enteric coating film in combination with the outer coating film allows application to large-intestine drug delivery.

Abstract: A composite film bag 1 for packaging comprises a composite film of a water-insoluble film 2 and a water-soluble polyvinyl alcohol film 3 which are adhered to one another to such an extent that the former film 2 can easily be peeled off from the latter film 3 and which are formed into a bag so that the water-insoluble film 2 serves as an outer layer of the bag and the water-soluble polyvinyl alcohol film 3 serves as an internal layer thereof. A powdery or liquid agricultural chemical agent 6 is packed in the composite film bag 1 and the opening of the bag is sealed. Upon practical use, the outer water-insoluble film 2 is peeled off to expose the internal film 3 and the internal film 3 as such, while containing the agricultural chemical agent 6, is introduced into water. Thus, the internal film is dissolved in water and in turn the content 6 thereof is released and accordingly dissolved in water. The composite film bag 1 is not broken at all even when it is exposed to a low temperature condition.
