Abstract
The invention discloses a preparation method of an environment-friendly bread packaging material. The packaging material comprises three layers, wherein the outermost layer is a paper layer, the middle layer is a bonding adhesive layer, the innermost layer is a laminating layer, and the material of the laminating layer consists of the following components in parts by weight: 100 parts of corn starch, 8-10 parts of carboxyethyl cellulose, 3-5 parts of alkyd resin, 14-16 parts of low-density polyethylene resin, 3-5 parts of glycerol, 4-6 parts of calcium stearate, 1-2 parts of liquid paraffin, 1.2-1.4 parts of calcium propionate, 1.4-1.6 parts of titanium dioxide and 1.5-2.5 parts of a silane coupling agent. The preparation method comprises the following steps: 1) preparing a laminating material; 2) adhering the laminating material to the paper layer through adhesive; 3) at the temperature of 70-80 DEG C, hot-pressing the laminating material prepared in the first step, the adhesive and the paper layer together.
Description
Technical field
The present invention relates to field of packaging material, relate in particular to a kind of preparation method of environmental protection bread packaging material.
Background technology
Along with the development of food service industry, but most bread packaging material are all take macromolecular compounds such as polystyrene, polyvinyl chloride, polypropylene as covering material, simultaneously these materials have the degraded of being difficult for, recovery difficult large, burn the feature such as toxic gas and harm ecological environment that produces.In addition, in process of production, the chemicals such as the permeability-reducing admixture, sizing agent, bleaching agent, coloring agent, stabilizing agent, ultra-violet absorber and the plasticizer that add in paper pulp.Migration occurs part chemicals harmful components under hot and humid environment is polluted food.In a word, bread wrapper is endangering to a certain extent the physically and mentally healthy of people and is bringing adverse effect to ecological environment.From 1 day September in 2009, food wrapper must have QS authentication marks to come into the market.Latest survey shows that chemical residues is seriously the underproof main cause of wrapping paper, therefore, in order to improve to greatest extent the security of bread wrapper, should need not or use as much as possible aborning food grade additives instead.WHO and Environmental Protection in China expert think, will initiate from now on that everybody uses nontoxic, harmless full paper-made environmental protection bag, and paper products are easy to corruption, both can reclaiming paper or do vegetable fertilizer, can reduce again environmental pollution simultaneously, and purify air.
Application number is that 02115925.4 patent of invention " a kind of solvable can edible composite corn starch packing-film and preparation method thereof " has been announced take cornstarch and konjaku as primary raw material and made respectively main glue and auxiliary glue, under the effect of plasticizer polyethylene glycol, ethylene glycol or D-sorbite through spraying, dry acquisition is solvable can edible composite corn starch packing-film.In manufacturing process, add the chemicals that in numerous food, limitation adds, easily cause harmful components osmosis pollution food in hot and humid situation, in addition, mechanical strength is little is difficult to meet processing request.
The article of " Packaging Engineering " the 1st phase Bian Xue, Cao Longkui in 2009 " potato residue is prepared the research of edibility inner packing membrane technology " research take potato residue as primary raw material, carragheen, sodium alginate be film forming agent, glycerine is that plasticizer is prepared edible packaging inner membrance, and packaging film indices is measured, there is the features such as smooth surface, dissolution velocity is fast, water absorption rate is low.But the packaging film color and luster that potato makes jaundice, attractive in appearance not, meeting water-soluble solution is packaging film major defect.
Application number is that 02115925.4 patent of invention " preparation method of water-soluble chitosan packing film " has been introduced a kind of packaging film preparation method take shitosan as primary raw material, in manufacturing process, add edibility composition (as white sugar, starch), water soluble ingredient polyvinyl alcohol, it is neutral that whole system is, the final dry food package film edible, soluble in water that obtains.But the polyvinyl alcohol adding in film permeates and contaminated food products in the situation that having water, therefore, the security of this packaging film need to improve, and in addition, merely all has the shortcoming a little less than mechanical strength by polysaccharide and the composite food package film that forms of other compositions.
Summary of the invention
The object of the invention is to propose a kind of preparation method of environmental protection bread packaging material, these packaging material are by the improvement of the component to covering material, and the bread packaging material safety and environmental protection of preparation, to overcome the defect of prior art.
For reaching this object, the present invention by the following technical solutions:
A kind of preparation method of environmental protection bread packaging material, these packaging material comprise three layers, outermost layer is papery layer, centre is bonding glue-line, innermost layer is coating layer, the material of described coating layer is made up of following component take weight portion: cornstarch is 100 parts, carboxyethyl cellulose 8-10 part, alkyd resins 3-5 part, ldpe resin 14-16 part, glycerine 3-5 part, calcium stearate 4-6 part, atoleine 1-2 part, calcium propionate 1.2-1.4 part, titanium dioxide 1.4-1.6 part, silane coupler 1.5-2.5 part; Described preparation method is:
1) by covering material mixing and stirring, then put into double helix extruder, by extrusion die extruding pelletization, extruding pelletization temperature is 160-170 ℃, then adopts single Screw Extrusion blow moulding machine to be blow molded into covering material at 165-175 ℃;
2) covering material is bonding by bonded adhesives and papery layer;
3) at 70-80 ℃, by the 2nd) covering material prepared of step, bonded adhesives be together with the hot pressing of papery layer.
Beneficial effect of the present invention is:
The present invention is by the improvement of opposite collation package material inner film coating material, take starch as main, add appropriate alkyd resins and ldpe resin and be used for improving obdurability, make the good environmental protection of this covering material in general, the covering material overwhelming majority can be with outer papery layer natural degradation, and adjust by above-mentioned component, make the mechanical strength of the bread packaging material of preparing good, internal layer waterproof and oilproof.And in inner layer material, do not contain poisonous and harmful substance, safety and environmental protection.
