Tóm tắt

As traditional food packaging materials, usage of petroleum-based plastics leads to serious problems due to poor biodegradability and renewability. The feasibility of using hemicellulose (HC) as a coating to prepare paper packaging materials with barrier properties was explored. Hemicellulose collected as by-product in dissolving pulp production was modified by carboxymethylation and hydroxypropylation, confirmed by FT-IR analysis. The prepared hemicellulose was cross-linked with the green crosslinking agent citric acid (CA) and applied to the surface of the paper to evaluate the effect of the coating on the barrier properties of the paper. When the coating amount reached 9.7 g / m
