    Biodegradation of blown films based on poly(lactic acid) under natural conditions

  • Original language description

    Commercially available polymer Bioflex? 219F, blend of Polylactic acid and biodegradable co-polyester, was used for film preparation, performed on mono-extrusion blown moulding machine. Resulting thin film was investigated on biodegradability in composting conditions for 6 weeks. The influence of microbial attack on mechanical, physico-chemical properties, weight loss and surface morphology was tested weekly. The results obtained during 6 weeks of composting indicate relatively good accessibility to biological degradation. Moreover, the time course of studied properties was observed through the test period.

    Biodegradace vyfukovaných folii na bázi polylaktidu v přírodníhc podmínkách

  • Czech description

    Komerčně dotupný polymer Bioflef 219F, směs polymeru kyselin mléčné a biorozložitelného kopolyesteru, byl použit pro přípravu jednovrstvé vyfukované folie. Výsledná folie byla podrobena kompostovacímu testu po dobu 6 týdnů. Byly sledovány změny mechanických, fyzikálně chemických vlastností, hmotností úbytek a povrchové vlastnosti vzorků. Výsledky dosažené po 6 týdnech kompostování naznačují dobrou kompostovatelnost daného materiálu.
