Preparing method of transfer print cellulose membrane for food

The invention relates to a cellulose membrane and a preparing method thereof, in particular to a transfer print cellulose membrane for food and a preparing method thereof. The method comprises the following steps: selecting raw material, preparing viscose glue, preparing films, desulphurizing, blenching, plasticizing, drying, humidifying, preparing coating dye and coating, and then a finished product is prepared; the finished product adopts cotton pulp and wood pulp as raw materials and has favourable transitivity; during heating and pressurization transfer print processing, food grade dye can be directly transferred to the surface of food, no packaging material substance can be penetrated into food, which achieves the purpose of green and environment protection packaging.
