Abstract
The invention discloses an environment-friendly bread paper laminating material. The thickness of the laminating material is 10-16 microns, and the tensile strength of the laminating material is greater than 8 MPa. The laminating material 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.
Description
Technical field
The present invention relates to field of packaging material, relate in particular to a kind of environmental protection bread wrapper covering material.
Background technology
Along with the development of food service industry, but most bread wrapping 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 ecotope that produces.In addition, in process of production, the chemical such as the permeability-reducing admixture, sizing agent, SYNTHETIC OPTICAL WHITNER, staining agent, stablizer, UV light absorber and the plasticizer that add in paper pulp.Migration occurs part chemical objectionable constituent 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 disadvantageous effect to ecotope.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 major 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 product 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 W-Gum and konjaku as main raw material and made respectively main glue and auxiliary glue, under the effect of softening agent polyoxyethylene glycol, ethylene glycol or Sorbitol Powder through spraying, dry acquisition is solvable can edible composite corn starch packing-film.In making processes, add the chemical that in numerous food, limitation adds, easily cause objectionable constituent osmosis pollution food in hot and humid situation, in addition, physical 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 internal packing membrane technique " research take potato residue as main raw material, carrageenin, sodium alginate be membrane-forming agent, glycerine is that softening agent is prepared edible packaging inner membrance, and packing film indices is measured, there is the features such as smooth surface, dissolution rate is fast, water-intake rate is low.But the packing film color and luster that potato makes jaundice is attractive in appearance not, meeting water dissolution is packing 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 packing film making method take chitosan as main raw material, in making processes, add edibility composition (as white sugar, starch), water soluble component polyvinyl alcohol, it is neutral that whole system is, the final dry food packaging 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 packing film need to improve, and in addition, merely all has the shortcoming a little less than physical strength by polysaccharide and the composite food packaging film that forms of other compositions.
Summary of the invention
The object of the invention is to propose a kind of environmental protection bread wrapper covering material, by the improvement of the component to covering material, make its grease-proof and waterproof, physical strength is good, and safety and environmental protection, to overcome the defect of prior art.
For reaching this object, the present invention by the following technical solutions:
A kind of environmental protection bread wrapper covering material, the thickness of this covering material is 10-16 μ m, tensile strength is greater than 8MPa, described covering material is made up of following component take weight part: W-Gum is 100 parts, carboxyethyl cellulose 8-10 part, Synolac 3-5 part, ldpe resin 14-16 part, glycerol 3-5 part, calcium stearate 4-6 part, whiteruss 1-2 part, calcium propionate 1.2-1.4 part, titanium dioxide 1.4-1.6 part, silane coupling agent 1.5-2.5 part.
Preferably, described covering material is made up of following component take weight part: W-Gum is 100 parts, 9 parts of carboxyethyl celluloses, 4 parts of Synolac, 15 parts of ldpe resins, 4 parts of glycerol, 5 parts of calcium stearates, 1.5 parts of whiterusss, 1.3 parts of calcium propionates, 1.5 parts of titanium dioxides, 2 parts of silane coupling agents.
Beneficial effect of the present invention is:
The present invention is by the improvement to covering material, take starch as main, add appropriate Synolac 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 natural degradation, this covering material waterproof and oilproof, and not containing hazardous and noxious substances, safety and environmental protection.
