MARINE BIODEGRADABLE PLASTICS COMPRISING A BLEND OF POLYESTER AND A CARBOHYDRATE-BASED POLYMERIC MATERIAL

NºPublicación: US2019276664A1 12/09/2019

Solicitante:

BIOLOGIQ INC [US]

Resumen de: US2019276664A1

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.

Resumen de: US2019276782A1

Disclosed herein are articles that include water-soluble films, where the water-soluble films include a polyvinyl alcohol (PVOH) polymer and a combination of at least three plasticizers. The combination of plasticizers includes dipropylene glycol as a first plasticizer, a sugar alcohol such as sorbitol as a second plasticizer, and a polyol such as glycerin as a third plasticizer. When the PVOH polymer and plasticizers are blended in particular proportions and/or selected with regard to various criteria related to physical and chemical film properties, the resulting water-soluble film formed from the PVOH resin blend exhibits beneficial combinations of aged tensile strength, aged melting transition delta elevation, aged adhesion value, and/or resistance to seal peeling, which provide strong film seals that retain their water-solubility characteristics.
