摘要： Composite blends of PBAT (or another similar polyester) with PLA and a carbohydrate-based polymeric material. While PLA is not compostable under home composting conditions (e.g., temperature of 28° C.) on its own, when blended in the manner described herein, it is compositable under such conditions. The addition of the PLA increases the rigidity of the composite blend, as PBAT on its own is so flexible as to be problematic for use in carryout bags, and the like. An exemplary blend may include 30-55% by weight of the carbohydrate-based polymeric material, up to 20%, or up to 15% by weight of PLA, with the balance of polymeric content being PBAT (e.g., 30-60% PBAT). Other components (e.g., an inorganic filler, such as calcium carbonate) may also be included in the blend.

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.

摘要： Described are very high molecular weight (e.g., over 2 million, such as 3-20 million g/mol) starch-based materials, and formulations including such, which can be spun in spunbond, melt blown, yarn, or similar processes. Even with such very high molecular weights, the formulations can be processed at commercial line speeds, with spinneret shear viscosities of 1000 sec−1, without onset of melt flow instability. The starch-based material can be blended with one or more thermoplastic materials having higher melt flow index value(s), which serve as a diluent and plasticizer, allowing the very viscous starch-based component to be spun under such conditions. The particular melt flow index characteristics of the thermoplastic diluent material can be selected based on what type of process is being used (e.g., spunbond, melt blown, yarn, etc.). The starch-based material may exhibit high shear sensitivity, strain hardening behavior, and/or very high critical shear stress (e.g., at least 125 kPa).

摘要： Sustainable thermoplastic carbohydrate-based polymeric materials, and sustainable plastic materials including an organic odor-reducing agent to counteract a slight burned carbohydrate odor resulting from inclusion of a carbohydrate-based polymeric material within the described materials. Such carbohydrate-based polymeric material may be starch-based, and the slight characteristic odor lent by such material may be that of a somewhat burned starch, such as a popcorn or caramel corn type odor. Applicant has found that this slight odor can be substantially removed by addition of a very small fraction of particular organic materials. 4-hydroxy-3-methoxybenzaldehyde (vanillin) has been found to be particularly effective, even in very small concentrations. Other freeze-dried fruit extracts (e.g., strawberry, raspberry, blueberry, etc.) may similarly be used. As little as 20 ppm of the organic odor-reducing agent is sufficient to substantially remove the characteristic burned starch odor. A ratio of the odor-reducing agent to the carbohydrate-based polymer may be less than 1:1000.

摘要： Described herein are blends of starch or starch-based materials with polymeric materials, where the starch or starch-based material is intimately blended with the polymeric material, so as to exhibit very small particles sizes (e.g., less than 2 μm, or less than 1 μm) for the starch or starch-based material in the matrix of the polymeric material. Such intimate dispersion of very small particles provides for far more of the particles dispersed more evenly throughout the matrix of the polymeric material, which may enhance various performance characteristics of the blended composite material. Methods of producing articles from such blends exhibiting such small particles and excellent dispersion are also disclosed.

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 one or more starches, and a plasticizer (e.g., glycerin). The carbohydrate-based polymeric material is less crystalline than the starting starch materials, e.g., being substantially amorphous, and having a crystallinity of no more than 20%. Third party testing shows blends of such materials render the entire blend biodegradable, believed to be due to the low crystalline substantially amorphous carbohydrate-based polymeric material breaking the hygroscopic barrier associated with the non-biodegradable plastic material, so that when blended together, both the plastic material and the carbohydrate-based polymeric material are biodegradable.
