    Step 3: taking the zein fiber magma of 100 parts by weight, the fibre modifier of 0.5-1 parts by weight is added, after being well mixed, Defibrination to beating degree is 45 ° of SR, shaping of manufacturing paper with pulp, obtains surface layer, wherein, the fibre modifier is by the nanometer of 0.5-1 parts by weight Zinc oxide, the magnesium sulfate of 3-5 parts by weight, the disodium ethylene diamine tetraacetate of 4-6 parts by weight, the calcium sulfite and 10- of 6-8 parts by weight After the triethanolamine mixing of 12 parts by weight, it is put into magnetization 2-3h in the magnetic field that magnetic induction intensity is 1.2-1.5T and is made；
    Step 4: after the upper surface of bottom spraying adhesive, bottom, adhesive layer and surface layer are sequentially placed, through pressure Squeeze, dry, obtain food wrapper.
  2. 2. the method for food wrapper is prepared with corn stalk fiber as claimed in claim 1, it is characterised in that the fermentation Specially：Added into the maize straw after crushing and account for the biogas slurry of maize straw weight 15% and 0.5% ferment bacterium, and add water The water content of adjusting corn stalk is 95%, after mixing, open fermentation 55 days.
  3. 3. the method for food wrapper is prepared with corn stalk fiber as claimed in claim 1, it is characterised in that the boiling Specially：Gained is filtered into upper thing 2-3h is steamed at 100 DEG C, regulation water content adds the 10- in terms of oven dry stock to 96-98% 15% ammonium sulfite, after being well mixed, 20-30min is incubated at 120 DEG C, adds the hydroxide of the 4-6% in terms of oven dry stock The hydrogen peroxide of sodium and the 4-6% in terms of oven dry stock, after being well mixed, 20-30min is incubated at 100 DEG C.
  4. 4. the method for food wrapper is prepared with corn stalk fiber as claimed in claim 1, it is characterised in that the corn Stalk is the mixture of maize straw skin, leaf and flesh, and the beating degree of the zein fiber magma is 35 ° of SR, and oven dry stock content is 8-10%.
  5. 5. the method for food wrapper is prepared with corn stalk fiber as claimed in claim 1, it is characterised in that the gluing Agent is by esterification starch, microcrystalline cellulose and polyvinyl alcohol by weight 2:2:3 are made.
  6. 6. the method for food wrapper is prepared with corn stalk fiber as claimed in claim 1, it is characterised in that the gluing The quantity for spray 1-2g/m of agent2, spray pressure 0.12-0.15MPa, spraying rate 180-200m/min.
