Films comprising a biodegradable Matrix phase and dispersed Phase, once dispersed in the Matrix phase and Absorbent articles comprising Said biodegradable Films

摘要

It provides a film that is biodegradable, which loses its Integrity over time.The degradable Film comprises from about 1 percent by weight to about 49 percent by weight of the weight of the film of a phase array including at least a biodegradable polyester,And since around 46 percent by weight to about 75% by weight of the film Weight of dispersed Phase comprising at least one oxidized Starch and at least one plasticizer, in which the dispersed phase is dispersed in the Matrix phase.And in addition, where the percent by weight of the weight of the film The Matrix phase is lower than the percent by weight of the weight of the film of the dispersed phase.The desired attributes of the film can be achieved in the present Invention by selectively control a variety of aspects of the Construction of Film as the nature of the components used, the relative amount of face to a component, the way in which The Film is formed and others.
