Effect of temperature and plasticizer content of polypropylene and polylactic acid on migration kinetics into isooctane and 95 v/v% ethanol as alternative fatty food simulants

Plasticizers are commonly used plastic additives. Deep understanding of their effect on the migration other substances is essential, especially for food contact materials. The kinetics four stabilizer-type additives from polypropylene (PP) and polylactic acid (PLA) with different tributyl acetyl citrate plasticizer content were investigated. results confirm that presence in plastics enhances swelling, thus strong correlation rate all additives, except PLA-Irgafos 168 samples. Migration kinetic experiments conducted at temperatures showed role temperature apparently exceeds plasticization. Nevertheless, hierarchical cluster analysis revealed similarity mechanisms stabilizers low high temperature, to content. • plasticized PLA PP was studied. increases Cluster a good tool compare swelling. Effect elevated resembles
