The invention relates to a piece of degradable
food packaging paper and a preparation method of the degradable
food packaging paper; the preparation method of the degradable
food packaging paper comprises the following steps of preparing konjak
sol, preparing
slurry, padding, degassing membrane-making and
drying,
waxing and airing. The preparation method provided in the invention takes
konjac glucomannan as main
raw material; soy isolate
protein and
carrageenan are added as accessories;
glycerol is used as a
plasticizer; without being bleached, the added
slurry does not contain carcinogens, such as dioxin,
organohalogen compounds and the like; the
fiber slurry is porous and has a
thick wall, so as to improve air permeability and strength of products effectively; the degradable food packaging paper prepared by the processes, such as
sol dissolving, mixing, swelling and smearing edible
paraffin wax and the like has the characteristics of safety, no
toxicity, environment-friendliness, etc., simultaneously, the
mechanical strength is distinctly improved; various added raw materials are in
food grade, so that
osmosis phenomenon which may happen cannot pollute food; and the degradable food packaging paper can be used as internal
package paper for food, such as
ice cream, cake, fry, etc.
