Abstract
The invention discloses an environment-friendly food packaging bag and a manufacturing process thereof. The food packaging bag comprises, by weight, 100-150 parts of water dropwort residues and bagasse, 50-80 parts of corn starch, 8-10 parts of propylene glycol, 2-4 parts of water-resistant agent, 1-3 parts of oil-resistant agent and 2-8 parts of precipitator. The environment-friendly food packaging bag has the advantages that the waste water dropwort residues and bagasse in food processing are used as main raw materials, the main raw materials are mixed with other supplementary materials to manufacture the food packaging bag, wastes are fully utilized while social value is created, social resources are saved, safety and environmental protection are achieved, and discarded food packaging bags do not pollute environments and can be further used as livestock feed or naturally degraded by microorganisms.
Description
Technical field
The present invention relates to packaging material for food field, be specifically related to a kind of environment-protective food package bag and manufacture craft thereof.
Background technology
Along with the progressively in-depth of environmental protection concept, degradable packing more and more receive an acclaim, particularly with the complete biodegradable plastics that starch, cellulose, polysaccharide etc. are primary raw material, and not only safety and environmental protection, and livestock feed can be used as further after discarding, fully economize on resources.Invention describes a kind of manufacture craft of environment-protective food package bag, with dead meal Chinese celery slag in food processing and bagasse for primary raw material, be aided with other batchings and produce enviroment protective packing bag, social value is created while waste is fully used, save social resources, safety and environmental protection, can not cause any pollution to environment after discarded, can be used as livestock feed further or pass through germ natural degradation.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of environment-protective food package bag and manufacture craft thereof.
The technical matters that the present invention solves can realize by the following technical solutions: a kind of environment-protective food package bag, and described food pack is made up of according to weight ratio following composition: Chinese celery slag and bagasse 100-150 part, cornstarch 50-80 part, propylene glycol 8-10 part, water repellent agent 2-4 part, oil-proof composition 1-3 part, precipitant 2-8 part.
Preferably, described water repellent agent is gum rosin, and described oil-proof composition is soya casein emulsion, and described precipitant is aluminium sulphate.
A manufacture craft for environment-protective food package bag, described manufacture craft is made up of following steps:
(1) Chinese celery slag and bagasse are added two times of water yield hydrabrusher pulpings, and then refine with fiberizer, be milled to slag slurry in the pasty state till;
(2) in slag charge, add cornstarch, propylene glycol, water repellent agent, oil-proof composition, precipitant by formula, then stir, be stirred to above-mentioned each composition and be all uniformly dissolved with water, become mixture, adjust PH to 6.0-6.2;
(3) carry out extruder grain with double screw extrusion machine to mixture, extrusion temperature is divided into 3 districts, and first district's temperature is 150 DEG C, and second district's temperature is 160 DEG C, and the 3rd district's temperature is 180 DEG C;
(4) after twin-screw extruder, the raw material single-screw extrusion machine after extruding is carried out blowfilm shaping, during blown film, charge temperature is 75 DEG C, and compression plasticization temperature is 95 ~ 115 DEG C, and blow-up ratio is 1:3, and haulage speed is 4m/min, and length-diameter ratio is 1:50;
(5) shaping rear cooling prepares food pack.
Beneficial effect is: the present invention is a kind of environment-protective food package bag and manufacture craft thereof, with dead meal Chinese celery slag in food processing and bagasse for primary raw material, be aided with other batchings and produce enviroment protective packing bag, social value is created while waste is fully used, save social resources, safety and environmental protection, can not cause any pollution to environment after discarded, can be used as livestock feed further or pass through germ natural degradation.
Detailed description of the invention
The following detailed description of the preferred embodiment of the present invention.
The detailed description of the invention of a kind of environment-protective food package bag of the present invention and manufacture craft thereof: a kind of environment-protective food package bag, described food pack is made up of according to weight ratio following composition: Chinese celery slag and bagasse 100-150 part, cornstarch 50-80 part, propylene glycol 8-10 part, water repellent agent 2-4 part, oil-proof composition 1-3 part, precipitant 2-8 part.Described water repellent agent is gum rosin, and described oil-proof composition is soya casein emulsion, and described precipitant is aluminium sulphate.A manufacture craft for environment-protective food package bag, described manufacture craft is made up of following steps: Chinese celery slag and bagasse are added two times of water yield hydrabrusher pulpings by (1), and then refine with fiberizer, be milled to slag slurry in the pasty state till; (2) in slag charge, add cornstarch, propylene glycol, water repellent agent, oil-proof composition, precipitant by formula, then stir, be stirred to above-mentioned each composition and be all uniformly dissolved with water, become mixture, adjust PH to 6.0-6.2; (3) carry out extruder grain with double screw extrusion machine to mixture, extrusion temperature is divided into 3 districts, and first district's temperature is 150 DEG C, and second district's temperature is 160 DEG C, and the 3rd district's temperature is 180 DEG C; (4) after twin-screw extruder, the raw material single-screw extrusion machine after extruding is carried out blowfilm shaping, during blown film, charge temperature is 75 DEG C, and compression plasticization temperature is 95 ~ 115 DEG C, and blow-up ratio is 1:3, and haulage speed is 4m/min, and length-diameter ratio is 1:50; (5) shaping rear cooling prepares food pack.
After above-mentioned processing step, obtain environment-protective food package bag, its with dead meal Chinese celery slag in food processing and bagasse for primary raw material, be aided with other batchings and produce enviroment protective packing bag, create social value while waste is fully used, save social resources, safety and environmental protection, any pollution can not be caused to environment after discarded, can livestock feed is used as further or pass through germ natural degradation.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention to do equivalent structure or the conversion of equivalent flow process, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
