Biodegradability of PP/PHBV (70/30) blend films
(2013-12-01)
This study aimed to investigate the biodegradation of polypropylene/ poly(hydroxybutyrate-co-hydroxyvalerate) (PP/PHBV) blend (70/30, w/w) films in soil, monitoring the evolution of CO2 using the respirometric method. The ...
Cross-linked soy protein as material for biodegradable films: Synthesis, characterization and biodegradation
(Elsevier, 2011-10)
The modification of soy protein isolate (SPI) with different amounts of a naturally occurring cross-linking agent (genipin, Gen) and glycerol used as plasticizer was carried out in this work. The films yielded were cast ...
Natural antimicrobial ingredients incorporated in biodegradable films based on cassava starch
(ELSEVIER SCIENCE BV, 2010)
Biodegradable films based on cassava starch and with addition of natural antimicrobial ingredients were prepared using the casting technique. The tensile properties tensile strength (TS) [MPa] and percent elongation (E) ...
Biodegradation of blend films PVA/PVC, PVA/PCL in soil and soil with landfill leachate
(Brazilian Archives of Biology and Technology, 2011-12-01)
This study investigated the biodegradation of blends films of poly(vinyl alcohol)/poly(vinyl chloride) (PVA/PVC) and poly(vinyl alcohol)/poly(caprolactone) (PVA/PCL) blends films prepared with dimethylformamide under a ...
Biodegradation of the Films of PP, PHBV and Its Blend in Soil
(Springer/plenum Publishers, 2009-12-01)
Films of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) and poly(propylene) (PP), PP/PHBV (4:1), blends were prepared by melt-pressing and investigated with respect to their microbial degradation in soil after 120 days. ...
Microstructure and thermal and functional properties of biodegradable films produced using zein
(2018-01-01)
Research is being conducted in an attempt to produce biodegradable packaging to replace plastic products, thereby reducing solid waste disposal. In this work, zein films were produced from vegetable oils (macadamia, olive ...
Biodegradability and plasticizing effect of yerba mate extract on cassava starch edible films
(Elsevier, 2016-10)
Biodegradable and edible cassava starch-glycerol based films with different concentrations of yerba mate extract (0, 5 and 20 wt.%) were prepared by casting. The plasticizing effect of yerba mate extract when it was ...
Biodegradation of blend films in soil and soil with chorume. I. PVC/PCL
(Research Journal Biotechnology, 2007-11-01)
Blends of synthetic and biodegradable polymers can be important in attaining material plastic degradation in the environment. Biodegradation using soil and chorume (liquid waste from landfill) microorganisms is a promising ...
Physical and Chemical treatments on Chitosan Matrix to modify film properties and kinetics of biodegradation
(Science and Education Publishing, 2013-11)
This work was focused on analyzing the effect produced by the addition of tannic acid as a crosslinking agent of chitosan matrix and the influence of the heat treatment applied. Taking into account those aspects relevant ...
