MULTILAYERED FILMS CAPABLE OF RELEASING ACTIVE INGREDIENTS OVER A LIMITED TIME PERIOD. |
摘要 |
<p>The present disclosure relates to a multilayer film capable of releasing an active ingredient, for example a pesticide. The film has a bottom or internal layer composed in part of a water-soluble polymer fraction containing the active ingredient, and a top or external layer. The bottom or internal layer may have a water-insoluble fraction in addition to the water-soluble polymer fraction. Relative proportions of the water-soluble polymer fraction and of the water- insoluble fraction provide a pre-determined time of release of the active ingredient when the multilayer film is exposed to humidity and/or moist conditions. The present disclosure also relates to methods of making the multilayer film and to uses of the film.</p> |
