Total soluble matter (TSM) and aspect observations of films of xanthan gum (XG), oxidized xanthan gum (XGox), chitosan (CS), and mixtures at 1:1 mass ratio. Standard deviation is for a minimum of three measurements.

Adhesive	TSM (%)	Observations
XG	100	Film dissolves completely, forming a solution with low viscosity.
XGox	78 ± 5	Film divides into smaller pieces and dissolves partially; no swelling observed in the surviving film pieces.
CS	100	Film dissolves completely, forming a highly viscous solution.
XG:CS	31 ± 2	Film dissolves partially, but maintains its integrity; swelling is visible, especially in the borders.
XGox:CS	20 ± 2	Film dissolves partially, but maintains its integrity; no swelling is visible.
