- •
Nano-TiO2 particle and HHP were used to improve functionality of PVA–CHI films.
- •
HHP changed layered microstructure of films into homogeneous and compact structure.
- •
HHP improved water vapor, gas barrier and mechanical properties of films.
- •
Nano-TiO2 gave PVA–CHI films with better antibacterial and mechanical properties.
- •
Nano-TiO2 migrated from 200 to 400 MPa treated films into olive oil was < 4.20 × 10− 3‰.
