Abstract
The utility model relates to a decomposable paperboard for a food container, which belongs to the class of household goods. In the utility model, one end of an original paper roll is made into thin film by T-DIE extrusion / hot press equipment and is pasted on the surface after made into liquid state by heating by using biologic decomposable material such as PET, or PLA, or starch, etc., and the biologic decomposable plastic material can be tightly pasted with fibre on the surface of paper; then, the paper surface of which the surface is provided with the biologic decomposable plastic material is treated in an electrostatic way to enable capillary bores thereof to be opened for the convenient operation of following other processing programs; food can directly contact the thin film. The utility model has the advantages that the cost is reduced, the bonding is tight, and the production rate is increased; the proportion of the biologic decomposable material contained in the utility model is low, the proportion is in conformity with the prescription of environmental protection and the unit price cost can be decreased thereby. The use is convenient, and the utility model can be made into paper wash-free tableware with various specifications and can effectively avoid the problem of environmental pollution.
Description
Technical field
The utility model relates to daily class, particularly a kind of decomposed cardboard that supplies the food prepared therefrom container to use.
Background technology
As everyone knows, paper food container commonly used, it includes: a box body made of paper, in order to take up food; One transparent adhesive film fits in this box body in order on the surface that takes up this food, and this glued membrane has prefabricated pattern in the face of a side of this box surface, and this pattern sees through glued membrane and outside being revealed in, and not with Food Contact; Wherein, transparent adhesive film is selected from plastic material or biodegradable starch materials such as PE, PP, PET;
The transparent adhesive film that said structure is fitted for the surface that takes up food in box body made of paper, its material emphasizes to use biodegradable starch material or PE, PP, PET plastic material, but this structure directly is printed on pattern the operation procedure of one transparent adhesive tape rete earlier, after its employed transparent adhesive tape rete must be made into the certain thickness complete lamellar body of tool in advance, just can carry out next step presswork, and other applying work; The shortcoming of this kind mode is:
1, procedure of processing complexity comprises: behind the transparent adhesive tape rete of the biodegradable material that it adopted through making sheet → carry out pattern printing → in box body one surperficial veneer made of paper; Wherein, aforesaid last applying program, between box body made of paper and transparent adhesive tape rete, must need to add medium---sticker, two members are fitted, and the transparent adhesive tape rete can't infiltrate in the cardboard fiber in the applying process, and the phenomenon that easily causes the transparent adhesive tape rete to have when sticker smears inequality to peel off produces;
2, holding the above-mentioned employed raw material of transparent adhesive tape rete is plastic material or biodegradable starch materials such as PE, PP, PET, because PE, PP and all non-biodegradable plastic of PET plastic material still can't natural decomposition, can cause the pollution of environment equally, in addition, this structure must be made the certain thickness lamellar body of tool earlier, add that raw material is more expensive, therefore, the higher shortcoming of cost is arranged.
The utility model content
The purpose of this utility model is to provide a kind of decomposed cardboard of using for the food prepared therefrom container, has solved the problems such as cardboard contaminated environment, cost height of existing used for packaging food.
The technical solution of the utility model is: drench biological decomposable PET or green plastic film layer of PLA or starch film layer on the film on a surface of paper roll, in order to this paper roll convenient follow-up be made into various as food containers such as paper lunch-box, dixie cup, paper pallet, cake bread boxs, this thin layer position can directly contact with various kinds of foods at the internal layer of container after making, and reaches effective reduction manufacturing cost and has the regulation that meets environmental protection concurrently.It mainly is that a end at paper roll is with PET or biological decomposable material such as PLA or starch based, through heat into aqueous after, make the film pouring through T-DIE extrusion/hot-press equipment again and be affixed on the surface, make the biological decomposable plastic cement material can be bonding with the fibre compact on paper surface, afterwards, the surface is had paper surface that biology can decompose plastic cement material with Electrostatic Treatment, its pore is opened, in order to follow-up other procedure convenient workings, food can directly contact above-mentioned film; The decomposable thin layer of said biology is a polylactic acid layers.
Advantage of the present utility model is: reduce cost, fit really, procedure of processing is oversimplified that high production rate can be provided; But its contained biology decomposing material ratio is lower, not only meets the regulation of environmental protection, more can reduce the unit price cost; It is comparatively convenient to use, and can make for the disposable utensils made of paper of various specification, more can effectively avoid problem of environment pollution caused.
Description of drawings:
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a partial schematic sectional view of the present utility model;
Fig. 3 to Fig. 6 is an embodiment schematic diagram of the present utility model.
The specific embodiment:
Shown in accompanying drawing 1 and accompanying drawing 2, the utility model mainly is to lay a biological decomposable starch based or the made thin layer 20 of materials such as PET or PLA on a surface of the cardboard 10 of paper roll to drench the film mode, significantly reduce to use higher-priced green plastic cement, reach effective saving manufacturing cost, prevent refuse pollution, bonding effect such as really.
The utility model after preheating, is first processing procedure through Electrostatic Treatment with the cardboard 10 of paper roll again; All biological decomposable PET or materials such as PLA particle or starch based are put into funnel, and heating through screw rod stirs into aqueously, and making as the film 20 as the foam through T-DIE extrusion/hot-press equipment again is second processing procedure; Above-mentioned second processing procedure drenched with the decomposable PET of biology or PLA or the made thin layer 20 of starch based be laid on above-mentioned first processing procedure and passed through on the surface of cardboard 10 of paper roll of preheating and Electrostatic Treatment, carry out powerful roll extrusion or extruding afterwards, the fiber that thin layer 20 is able to cardboard 10 is that the surface fits tightly, through Electrostatic Treatment the pore that cardboard 10 is fitted with biological decomposable PET or PLA thin layer 20 surfaces is opened again, last rewinding again becomes the paper roll of whole volume, after cutting into sheet, the disposable utensils made of paper that are beneficial to various size are made, to shown in the accompanying drawing 6, use the cardboard that decomposes of the present utility model can be made into paper dining plate 30 as accompanying drawing 3, paper tray 40, dixie cup 50 and paper bowl 60 etc.
