Description
Technical field
The present invention relates to a kind of natural moistureproof degradable food packaging paper and preparation method thereof, belong to food service industry technical field.
Background technology
Along with the development of food service industry, food wrapper kind is the most various, and relatively common have cake paper, candy wrapper,
Fine dried noodles carton, bakers paper, cookies carton, ice-cream outer package paper using, wherein waterproof and oilproof type food wrapper is the blueest or green
Look at, however most all with macromolecular compounds such as polystyrene, polrvinyl chloride, polypropylene as covering material, simultaneously
These materials have that the most degradable, recovery difficult is big, burn and produce the feature such as toxic gas and harm ecological environment.Additionally,
In process of production, in paper pulp, the permeability-reducing admixture of addition, sizing agent, bleach, stain, stabilizer, ultraviolet are inhaled
Receive the chemicals such as agent and plasticizer.The harmful components generation migration in the environment of hot and humid of part chemicals makes food be subject to
Pollute.In a word, food wrapper endanger to a certain extent the physical and mental health of people and bring to ecological environment unfavorable
Impact.
But being as socioeconomic development and the enhancing of popular environmental consciousness, research and development one has frivolous nothing transparent, colourless
Taste, nontoxic degradable, degradable wrapping paper have become as the major trend of World of Food industrial technology development, are also not
Carry out the Main way of food packing industry development.
The degradable food package film utilizing natural biologic material such as soybean protein to prepare is had to pack for oily food at present,
But edible packaging is the most extensive, can't replace synthesis macromolecule plastic film, and its reason is main
Being the bad mechanical property of film, natural edible polymer material itself has hydrophilic, and its resistance is moist limited, simultaneously its
The packaging problem such as heat sealability and impressionability need to solve.
Summary of the invention
Goal of the invention: in order to overcome the defect of prior art, it is an object of the invention to provide a kind of natural moistureproof degradable food
