INVESTIGATION OF MECHANICAL PROPERTIES OF BACTERIAL NANOCELLULOSE/ POLYVINYLIDENE FLUORIDE DOUBLE-LAYER FILMS

Considering that biodegradable materials are still failing to meet a wide range of functional requirements previously fulfilled by synthetic polymers, one of the ways to overcome that problem is increased share of biodegradable layers in the multilayer packaging materials. Double-layer films, containing biodegradable bacterial nanocellulose (BNC) layer and polyvinylidene fluoride (PVDF) layer have been prepared as a step towards a reduced share of traditional packaging plastics. Mechanical properties of double-layer films depending on the thickness of the PVDF layer have been investigated and presented in this study.
