The invention relates to the technical field of membrane material research and development and preparation and discloses a novel green degradable high-elasticity membrane material. Modified hemicellulose has good compatibility with sorbitol, the two components infiltrate into each other and are tightly integrated, micro-molecules replace hydrogen bonding of hemicellulose macro-molecules, the micro-molecules and hemicellulose macro-molecule chains form a three-dimensional network-like structure in a hydrogen bond way, membrane material cracks are gradually decreased, a membrane becomes soft, thus the membrane formation performance is improved, the membrane has very high elasticity and ductility, the thickness is as small as 0.05 mm, the transparency is high, the te |
