Tested were the basic application properties of blends from thermoplasticized wheat starch (TPWS) and poly-epsilon-caprolactone (PCL) in different mixtures stored at different humidities for up to two months. It was shown that important improvements in the water vapour barrier properties, the tensile-stretching behaviour and the aging embrittlement are only possible for a PCL percentage of 50 per cent. But these are accompanied by increased oxygen permeability. The results stand in contrast with properties of commercially available starch/PCL basis film material which have obviously shown better properties by using biologically non-degradable synthetic thermoplastics.deagingAlterungbarrier propertiesKunststoff-Folieoxygen permeabilityplastics filmPrüfungSauerstoffdurchlässigkeitSperreigenschaftstarchStärketestingWaserdampfdurchlässigkeitwater vapour permeability664688658journal article
