Abstract
The present invention relates to food container and package, and the elastic completely degradable tableware is prepared with plant fiber, stuffing adhesive and degrading agglomerate glue. The plant fiber includes stalk, rice straw, husk, bagasse, corn cob, bamboo bits, peanut shell, etc; the stuffing adhesive is starch; and the degrading agglomerate glue is mixture of polypropylene, photosensitizer and talcum or calcium carbonate. It is prepared through high temperature heating, extruding, stoving and pressing to form. The technological process is pollution-free, simple, low in power consumption, short in production period, high in efficiency and low in cost. The tableware product has the advantages of being completely degradable, resistance to water and oil at 100 deg.c, resistance to freezing, resistance to food corrosion, certain elasticity and fastness.
Description
The present invention relates to food product containers or packing.
China from the reform and opening-up since, the national economy fast development.For adapting to the fast pace of the modern life, snack food product also arises at the historic moment.The utensils for snack consumption of macromolecular material is very big.The food product containers of these high molecule plastic goods or packing, after use is discarded, the cost recovery height.Bury undergroundly, be difficult to degraded, destroy Soil structure: the combustion fire burns, and produces harmful exhaust, destroys the eubiosis, and consequence causes anxiety, and brings threat to existent environment of people.For this reason, searching and development and production process do not have the three wastes, use back free of contamination snack food product container of waste easy-clear or wrapped product to become the task of top priority.
Existing degradable disposable dinner (beverage) containers mainly contains following four classes:
1, moulded paper pulp product.Form with paper mould, need to produce earlier paper pulp, production process discharging waste liquid causes black pollution.The production cost height lacks the market meaning and strives power.
2, decomposable plastics goods.After discarded, can resolve into fragment, but can not continue to be degraded to innoxious substance, fragment accumulates in soil, still can cause soil compaction, influences crop growth.
3, plant fibre moulding article.Its waste does not produce toxic and harmful by burning, and its ashes enter soil, can also make fertilizer: directly imbed the soil and can be subjected to microbiological deterioration to become innoxious substance.But production efficiency is low, the product lacking toughness, and transportation is easily broken, and using has limitation.
4, plant-fiber elastic goods.Advantage with plant fibre moulding article is burned pollution-freely, buries high-fall separating, and flexible difficult fragmentation.Product cost is low, and the production efficiency height is the kind that the utmost point has market outlook.
The high-fall production technology principle of separating elasticity food and drink tool of starch plant fiber is that degradation master batch moment extruding is broken to form under the effect that colloid outflow and starch and vegetable fibre be blended in mould and formed new reticulated structure under high temperature extruding, the mutual bonding fixed effect of playing of colloid, starch and vegetable fibre, also have simultaneously waterproof, grease proofing performance, reach the functional effect of food and drink tool.
The high-fall degraded ultimate principle of separating elasticity food and drink tool of starch plant fiber is used for realizing by light, heat, microorganism multiple degrading.
1, photochemical effect.In sizing material, add photosensitizers, after illumination, generate energy, with cause sizing material by macromole become small molecules be molecular weight by the hundreds of thousands of cracking to thousands of, the sizing material molecular rupture makes sizing material lose intensity and elasticity, creates conditions for microorganism eats up the sizing material molecule.
2, thermochemistry effect.Contain the thermal response catalyzer in the degradable master batch, nature be heated or composting fermentation process in produce heat after.This catalyzer can impel the sizing material macromolecular cleavage to diminish, and its result is identical with light reaction behind the molecular rupture.
3, microbiological deterioration.Add through the ultra-fine starch of special processing in the sizing material and can be engulfed by bacterium, when sizing material molecular weight degradation to 6000 is following, can become the nutrition source of certain micro-organisms simultaneously, fallen by microbiological degradation at occurring in nature
4, degradation cycle is adjustable.Decide on demand,, be controlled at degraded about 20,45,90,180,360 days respectively by the photosensitizers proportion in the change degradation master batch and the proportion of the biodegradation agent in the compound material.This product is inoperative to electric light light, therefore can keep original performance in shelf lives and usage period.
The objective of the invention is to provide a kind of can be high temperature resistant, anti-freezing, waterproof and oilproof is non-leakage, the corrosion of anti-food, and is flexible, fastness good, it is broken to be difficult for, and meets the food product pack hygienic requirements, the disposable food or beverage container that can all degrade behind use discarded.And production process is easy, does not have any pollution, the production technique that energy consumption is little, with short production cycle, efficient is high, cost is low.
The present invention is achieved in that the high-fall elasticity food and drink tool of separating of vegetable fibre, mainly is made up of vegetable fibre and filling adhesive, degradable master batch glue.Wherein, vegetable fibre comprises, crop tangerine bar, straw, husk, bagasse, corn cob, bamboo bits, Pericarppium arachidis hypogaeae etc. meet the vegetable fibre that food sanitation requires: filling adhesive is a starch: the degradable master batch agent is that polypropylene (PP) and photosensitizers and talcum powder or lime carbonate mix.
The formula rate of degradable master batch glue is:
Polypropylene 89.8% or 898 kilograms
Photosensitizers 0.2% or 2 kilograms
Talcum powder or lime carbonate 10.0% or 100 kilograms
The high-fall proportioning raw materials of separating elasticity food and drink tool of starch is:
Starch 50%～60%
Degradable master batch glue 40%～50%
The high-fall proportioning raw materials of separating elasticity food and drink tool of vegetable fibre is:
Plant fiber powder 30%～40%
Starch 20%
Degradable master batch glue 40%～50%
Food color is pressed product requirement, ratio with addition of.
The high-fall production technique of separating elasticity food and drink tool of starch plant fiber, its step is as follows:
(1) vegetable fibre is pulverized 60 order to 100 orders:
(2) per-cent by following raw material gross weight takes by weighing raw material:
Plant fiber powder 30%～40%
Starch 20%
Degradable master batch glue 40%～50%
Food color is an amount of
(3) (2) described starch and degradable master batch glue are mixed, stand-by:
(4) insert together in the container of belt stirrer with (2) described plant fiber powder with according to the proper amount of edible pigment of product requirement, slowly spray into the water that accounts for raw material gross weight 5～10% while stirring: under agitation slowly add (3) gained mixture again, promptly get and produce the high-fall compound of separating elasticity food and drink tool of starch plant fiber.
(5) (4) gained compound is progressively inserted in the extrusion sheet machine funnel, be heated to about 180 degree, be extruded into sheet material, find time and output by the thickness of product, the door width of cloth and weight decision.
(6) (5) resulting sheet is placed on carries out drying and forewarm on the high speed Autoformer, about about 120 degree, through compression moulding.
(7) take out blank, promptly get the high-fall elasticity food and drink tool product of separating of starch plant fiber of the present invention through cutting.
