Abstract: 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).

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Described are starch-based materials, and formulations including such, which can be spun in spunbond, melt blown, yarn, or similar processes. Even with high viscosity resulting from inclusion of the starch-based materials, the formulations can be processed at commercial line speeds, with spinneret shear viscosities of 1000 sec−1, or even up to 4000 sec−1, without onset of melt flow instability. Viscosity and other processing characteristics can be improved by addition of an acid or acid anhydride, and/or by use of sorbitol as the plasticizer, when forming the starch-based material. The starch-based material can be blended with one or more thermoplastic materials, e.g., having higher melt flow index value(s), allowing the blend to be spun. 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.).

Abstract: 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.
