The compositions are formed into films, sheets, and articles.

The biodegradable resin composition according to the present invention contains an aliphatic polyester biodegradable resin and fibrous basic magnesium sulfate.

An earth plant-based compostable biodegradable composition for the formation of a bioplastic and method of producing said resin, the composition comprising: about 17.5 to 45% ethanol-based green polyethylene by weight, about 20 to 25% calcium carbonate by weight, about 2 to 12% hemp hurd or soy protein by weight, about 32 to 45% starch by weight, and about 0.5 to 1% biodegradation additive by weight to enable biodegradation and composting of the bioplastic; wherein the composition is produced by first mill grinding the ethanol-based green polyethylene, calcium carbonate, hemp hurd or soy protein, starch and the biodegradation additive into fine powders, then mechanically mixing the fine powders one by one into a final mixture for about 5-25 minutes at a time, dry and without heat, and then heating the final mixture to about 220 to 430 degrees Fahrenheit.

The use of inhibitory calcium carbonate as additive for a composition containing at least one polymer different from cellulose, wherein the inhibitory calcium carbonate is obtainable by means of a method in which calcium carbonate particles are coated with a composition comprising, based on its total weight, at least 0.1% by weight of at least one weak acid. Further described is a composition containing at least one polymer different from cellulose and inhibitory calcium carbonate.

A composition for fused filament fabrication may include polylactic acid resin and talc. The composition may range from 50% by weight to 99% by weight polylactic acid resin, and from 7% by weight to 40% by weight talc. The composition may be configured as filaments or pellets adapted to be used in a fused filament fabrication process. A method for generating a resin-based structure may include providing a resin source that may include polylactic acid resin and talc. The resin source may include from 50% by weight to 99% by weight polylactic acid resin, and from 7% by weight to 40% by weight talc. The method may also include heating the resin source to a temperature greater than the melting temperature for semi-crystalline resins or significantly greater than glass transition temperature for amorphous resins, and depositing the heated resin source in a layered manner to form the resin-based structure.

A biopolymer blend is provided that comprises a combination of three components: poly (butylene adipate-co-terephthalate) (PBAT); agriculture sourced polylactic acid (PLA); and engineered proteinaceous eggshell nanoparticles. The two polymer components can be present in any ratio but an approximate 70:30 ratio is preferred. The engineered proteinaceous eggshell nanoparticles are preferably about 10-25 nanometers. Also provided are methods of preparing biopolymer film and packaging components. Pelleted poly (butylene adipate-co-terephthalate) and agriculture sourced polylactic acid (PLA) are dissolved in chloroform and mixed together to form a polymer blend, and engineered proteinaceous eggshell nanoparticles are incorporated into the polymer blend, which is then extruded to create a biopolymer film or component.

One or more techniques and/or systems are disclosed for a dry-type lubricant for use in a dry product hopper to help improve dry product flow and to improve anti jamming properties of the dry product. The example lubricant can comprise a hydrophilic fiber, such as cellulose, having a width to length aspect ratio that provides a thin fiber. A plurality of hydrophobic particles are deposited on the surface of the fiber, resulting in a fiber surface exhibiting amphiphobic properties. Further, the fiber can operably absorb water, and then releases the absorbed water to the surface of the fiber under mechanical stress, such as when mixed with a product in a hopper. This can result in the water being disposed on the surface of the fiber, to provide lubrication to a product in a hopper to improve flow and anti jamming characteristics of the product in the hopper.

Disclosed herein are compositions and articles made therefrom, the compositions and articles comprising at least one hydrocolloid, at least one plasticizer, at least one filler and/or humectant and water. Typically, the components are derived from biological sources, such as seaweed, plants, or animals. Typically, the components are made from food quality ingredients, making the compositions and articles edible and/or biodegradable. The compositions are used to form articles, such as straws, and the articles have desirable flexibility and moisture barrier properties, such as swelling resistance, as well as biodegradability and/or compostability properties.

A foamable composition comprising at least one cellulose acetate, a plasticizer, a nucleating agent, and either a chemical blowing agent or a physical blowing agent is disclosed. The composition is formed into foamed articles that are biodegradable.

A package or container contains a biodegradable resin and a microcapsule including therein a decomposition accelerator for the biodegradable resin. The microcapsule includes an outer shell containing a resin composition having photodegradability.
