  • Patent number: 9718258
    Abstract: A film that contains a core layer positioned adjacent to an outer layer is provided. The core layer contains a relatively high percentage of thermoplastic biopolymers that are both biodegradable and renewable. Despite being biodegradable and renewable, many biopolymers tend to be relatively stiff in nature. The present inventors have discovered, however, that through selective control over the components in the core and outer layers, a film can be readily formed having good mechanical properties. Among other things, this is accomplished by blending the biopolymer in the core layer with a polyolefin. A polyolefin is also employed in the outer layer. In addition to providing functionality to the film (e.g., heat sealing, printing, etc.), the polyolefin-containing outer layer also helps counteract the stiffness of the biopolymer in the core layer, and helps improve processability, stiffness, and ductility.

  • Patent number: 9456931
    Abstract: A tampon applicator that is water-sensitive (e.g., water-soluble, water-dispersible, etc.) in that it loses its integrity over time in the presence of water is provided. The tampon applicator can be discreetly disposed of in a toilet without the risk of clogging sewer pipes. The tampon applicator includes a molded thermoplastic composition containing at least one partially hydrolyzed polyvinyl alcohol a plasticizer. The desired water-sensitive characteristics of the tampon applicator may be achieved in the present invention by selectively controlling a variety of aspects of the thermoplastic composition from which the applicator is formed, such as the nature of the components employed, the relative amount of each component, the manner in which the composition is formed, and so forth.
