A gastropod repellent film of the present invention includes at least an inorganic filler layer containing an inorganic filler and a thermoplastic resin. The inorganic filler layer is an outermost layer. The inorganic filler includes calcium carbonate particles. The inorganic filler has a percentage content of greater than 50.0% by mass in the gastropod repellent film. The gastropod repellent film has a density of at least 1.05 g/cm.sup.3 and no greater than 1.25 g/cm.sup.3. A plant cultivation method of the present invention uses the gastropod repellent film.

An antimicrobial spray composition is disclosed, forming a protective film on surfaces when dried. The protective film provides antimicrobial protection by killing at least 95% of microorganisms in <30 minutes of exposure. The spray composition comprises a sulfonated polymer selected from the group of perfluorosulfonic acid polymers, polystyrene sulfonates, sulfonated block copolymers, sulfonated polyolefins, sulfonated polyimides, sulfonated polyamides, sulfonated polyesters, sulfonated polysulfones, sulfonated polyketones, sulfonated poly(arylene ether), and mixtures thereof. The sulfonated polymer has a degree of sulfonation of at least 10%

In one aspect, the disclosure relates to antimicrobial films for use on high-touch surfaces in medical, commercial, and residential settings and methods of making the same. The films and coatings are robust and retain activity over time and are optimized to minimize diffusion time of virus particles as well as bacterial and fungal pathogens to the inactivating layers and/or particles in the films and coatings. In another aspect, the films and coatings are capable of inactivating multiple virus, bacteria, and fungi types, can be applied as sprayable coatings or adhesive backed films, or can be incorporated into fabrics. In still another aspect, the films and coatings can be formulated as transparent or can be a neutral color such as gray or white.
