DEGRADABLE MATERIALS AND PACKAGING MADE FROM SAME

A water-soluble film, comprising a first water-soluble film, wherein the first water soluble film disintegrates in water within less than about 24 hours and dissolves in water within less than about 48 hours as measured by the MSTM-205 at 20° C. The disclosure provides a water-soluble film comprising a first water-soluble film that disintegrates in water within less than 24 hours and dissolves in water within less than 48 hours as measured by MSTM-205 at 20° C. The first water-soluble film optionally may be further characterized in that it does not disintegrate in water for at least about 1 hour and does not dissolve in water for at least about 1 hour as measured by MSTM-205 at 20° C. The disclosure further provides a water-soluble film comprising a first water-soluble film characterized in that the degradation and/or dissolution of the first water-soluble film is adapted to be activated by consumer handling.

Renewably-Sourced Biodegradable Polyolefin Packaging, Utensils, and Containers

Renewably-sourced biodegradable polyolefin packaging, utensils, and containers include a renewably-sourced polyolefin (for example, polyethylene and polypropylene) and a biodegrading agent. The renewably-sourced biodegradable polyolefin packaging is made from plant materials typically by polymerizing olefins that are made from reducing alcohols created by fermenting plant materials. An example of a suitable plant material is sugarcane and its derivatives. The biodegrading agent accelerates the biodegradation of polyolefin packaging even in anaerobic and dark (i.e., absent of ultraviolet light) environments. Such a packaging is particularly useful for packaging frozen food that is to be microwaved in the packaging. The package is also particularly usable as packaging for frozen comestibles, which are often stored at dry-ice temperatures. Ultimately, the renewably-sourced biodegradable polyolefin packaging provides a start-to-finish green packaging that meets the requirements of being renewably sourced, biodegradable in landfills, and having similar performance as traditional polyolefin packaging.

COMPOSITIONS AND METHODS FOR USE IN PLASTICS MANUFACTURING

Compositions and methods for making biodegradable plastic products are provided. The compositions include a destabilizing agent that makes the finished plastic biodegradable. The compositions also can include an oil-based carrier, such as cottonseed oil, that allows the biodegrading agent to be metered into a continuous plastic manufacturing process. The compositions further can include an additive that allows the biodegrading additive to combine with the carrier; an optical brightener to improve the appearance of the finished plastic product, and to indicate the presence of the composition in the finished product; and a pigment, so that the composition can act as a liquid coloring agent.
