Biodegradable alginic acid film material and application thereof

The invention discloses a biodegradable alginic acid film material and application thereof, the film material comprises the following raw materials: 40-60 parts of sodium alginate, 20-30 parts of carrageenan, 2-10 parts of a curing agent, 1-5 parts of a cross-linking agent, 0-30 parts of an inorganic filler, 1-5 parts of a plasticizer, and 0.1-1 part of fresh-keeping slow-release particles, the biodegradable alginic acid film material is prepared from natural polysaccharides, in the preparation process, the additive is mainly calcium carbonate, so that the preparation cost of the membrane material can be greatly reduced; meanwhile, the carrageenan is used, the carrageenan has good thermal stability, after the carrageenan is mixed with the sodium alginate, the thermal degradability of the sodium alginate can be improved, and the mechanical property of the membrane material is improved. 本发明公开了一种生物降解海藻酸薄膜材料及其应用，所述的薄膜材料原料包括海藻酸钠40-60份、卡拉胶20-30份、固化剂2-10、交联剂1-5、无机填料0-30、塑化剂1-5、保鲜缓释颗粒0.1-1份，所述生物降解海藻酸薄膜材料由天然多糖制备得到，具有生
