Processing Technologies of EVOH/Nano-SiO2 High-Barrier Packaging Composites
The ethylene-vinyl alcohol copolymer(EVOH)/nano-SiO2 composites were prepared by meltblending with different processing technologies(melt blending technology and film-blowing technology) andblown to film. The structure of the EVOH/nano-SiO2 composites was analyzed through polarizing microscope(POM) and differential scanning calorimetry (DSC). The mechanical properties, barrier properties and transparencyof the composites were characterized. The results showed that: different film-blowing processes canchange the ordered structure and crystalline form of the EVOH/SiO2 nanocomposites film, different blendingtechnologies have a great effect on the structure of the composites and different processing technologies havea great effect on the properties of EVOH and EVOH/nano-SiO2 nano-composites film.
