    摘要： Described herein are methods for rendering biodegradable a plastic material that is not itself biodegradable, by blending the plastic material with a carbohydrate-based polymeric material that is formed from a) one or more starches and a plasticizer (e.g., glycerin), b) an additive known in the art as an OXO material and/or an additive that interacts with microbes that contribute to biodegradation of the non-biodegradable material. The carbohydrate-based polymeric material is less crystalline than the non-biodegradable materials, e.g., being substantially amorphous, and having a crystallinity of no more than 20%. When tested under conditions causing biodegradation, the blend biodegrades to an extent greater than the content of the carbohydrate-based polymer.

    摘要： Described herein are methods for increasing strength of blown films, by forming the films using a film blowing apparatus where the film is formed from a blend of a first polymeric material and a renewable carbohydrate-based polymeric material having particular characteristics. By using such a blend, and ensuring that the film blowing apparatus is operated at a high blow up ratio of at least 2.0, and/or using a narrow die gap of no more than 500 microns, Applicant has discovered that increased strength in the film can be obtained, as compared to where (i) the renewable carbohydrate-based polymeric material is not included or (ii) where the film is blown at lower blow up ratios and/or wider die gaps.

    摘要： Described herein are blends of carbohydrate-based polymeric materials with other polymeric materials, where the carbohydrate-based polymeric material is intimately blended with the other polymeric material, so as to exhibit very small particles sizes (e.g., less than 2 μm, or less than 1 μm) for the carbohydrate-based polymeric material in the matrix of the other polymeric material. Such intimate dispersion of very small particles provides for far more of the particles dispersed more evenly throughout the matrix of the other polymeric material, which may enhance various performance characteristics of the blended composite material, and provide for more consistent achievement of such characteristics, from batch to batch. Methods of producing articles from such blends exhibiting such small particles and excellent dispersion are also disclosed. While suitable for use in a wide variety of fields, examples may include for the coating of paper cups, and as a capsule material for sustained release fertilizer.

    摘要： Composite blends of polyester containing plastic materials, and a starch-based polymeric material that increases the biodegradability of the polyesters of such a composite in simulated or actual marine conditions (e.g., simulated by ASTM D-6691). Enhanced rate or extent of biodegradation may also be exhibited in simulated or actual land-based disposal conditions. The starch-based polymeric materials are substantially amorphous, and are homogenously blended with the polyester plastic materials. While polyester plastics such as PBAT, PLA, PCL, and/or PBS may exhibit some biodegradability characteristics when composted and/or disposed of in landfill conditions at elevated temperatures, they exhibit limited if any biodegradability when disposed of in a marine environment. Even conventional blends of starch with such polyesters do not exhibit any significant marine biodegradability with respect to the polyester components therein. Third party testing shows the present blends exhibit substantially complete biodegradability of the entire composite under marine conditions, after about 400 days.
