Biofilms were synthesised from glucomannan and xylan. The ratio of glucomannan: xylan varied from 90:10 (g/g) to 70:30 (g/g). Nanofibrillated cellulose was added to enhance the mechanical properties of the biofilms. In another approach, glucomannan/xylan suspensions were crosslinked with tartaric acid (TA) or citric acid (CA). To evaluate printing on the crosslinked biofilms, a FlexiProof 100 laboratory proofer was used to print on the surface using water-based flexographic inks. The findings confirmed that crosslinked biofilms exhibited higher mechanical and barrier properties than non-crosslinked films. TA-crosslinked films provided the best moisture barrier properties, while CA-crosslinked films exhibited the highest tensile strength and elongation. Printability analysis revealed that all biofilms had acceptable print contrast and optical density values; the non-crosslinked biofilms showed the maximum print contrast value. The findings of this research recommend that crosslinked glucomannan-xylan biofilms are promising candidates for sustainable food-packaging applications with good printability, mechanical strength and moisture resistance.
