A water-soluble film which comprises a saceharide component and a vinyl alcohol resin component, where the vinyl alcohol resin may include functional comonomer units such as sulfonic acid functional groups or salts thereof. Preferred are polyvinyl alcohol / 2-methylacrylamido-2 methyl propane sulfonic acid resins (PVOH / AMPS) which may be purchased commercially with relatively higher or relatively lower characteristic viscosity. The films exhibit superior resistance to aggressive oxidizing chemicals and remain soluble in water after prolonged exposure thereto. The films are particularly useful for unit-dose packaging of chlorine-containing pool chemicals, such as trichloroisocyanuric acid.

The invention belongs to the technical field of mulching films and particularly discloses a liquid-state mulching film and preparation and use methods thereof. The main technical scheme is as follows: the preparation and use methods comprise the steps of taking sludge, and adding a sterilizing agent prepared from water-dissolved trichloroisocyanuric acid, so as to deodorize and sterilize; then, adding humic acid raw powder, inorganic salts and water, mixing, stirring and homogenizing, then, grinding and reacting, so as to prepare a master batch formed by a paste body; taking polyacrylamide and derivatives thereof, lignosulfonate or / and cellulose derivatives, so as to form a sub-material with film forming, penetration, dispersion, chelation and water retention properties; during use, dissolving the sub-material by water, adding the dissolved sub-material into the master batch, stirring to prepare a porridge-like body, then, adding water, uniformly stirring and diluting, and spraying by a mist sprayer, thereby forming the mulching film. The liquid-state mulching film is prepared in a manner that the sludge serves as a main material, so that the problem of sludge treatment is basically solved, especially, the waste is changed into the valuable, and the land capability can be greatly increased; the liquid-state mulching film has the functions of increasing temperature, preserving soil moisture and promoting crop growth, the elimination of white pollution is realized, the flying dust factor of agriculture is controlled, the soil is improved, water resources are conserved, the revenue of farmers is increased, the expenditure of farmers is reduced, and the sustainable development of agriculture is promoted.
