Abstract
The invention belongs to the papermaking technology, and relates to a production method of raw paper of fruit fresh-keeping paper. The method comprises the steps of basic raw materials comprising unbleached chemical broadleaf wood pulp and unbleached chemical softwood pulp are subjected to pulp dispersion, pulp grinding, pulp mixing, wet-end chemical addition, sizing, dewatering, drying and coiling to obtain finished paper; the method is characterized in that wet-end chemicals include a softener food-grade long-chain alkyl compound, polyamide epoxy resin and aluminum sulfate; the amount of the unbleached chemical broadleaf wood pulp in the two basic raw materials is 60-90 wt%, and the amount of the unbleached chemical softwood pulp is 10-40 wt%. The raw paper has the advantages of high food safety, high wet strength, soft paper texture and good packaging performance.
Description
Technical field
The invention belongs to paper technology, relate to a kind of production method of fruit preservative paper body paper.
Background technology
The utilization of fruit preservative paper on preserving fruit and vegetable utilizing is more and more extensive, and fruit preservative paper is passed through on body paper, process the special fresh-keeping layer of one deck, to realize the anti-corrosive fresh-keeping of gourd, fruit and vegetable and to extend memory time.The fruit preservative paper of current use is former exists the shortcomings such as food security does not ensure, the wet rear paper cracky of the stiff packaging weak effect of paper, moisture absorption chance more.
Summary of the invention
The present invention want technical solution problem to be, provide a kind of there is food security, the production method of wet strength is high, papery is soft, packaging character is good fruit preservative paper body paper.
The production method of fruit preservative paper body paper of the present invention is: by this colour chemistry of base stock hardwood pulp and this colour chemistry softwood pulp through loose slurry, defibrination, with slurry, interpolation wet-end chemicals, starching, dehydration, drying, batch and obtain into paper, wherein: in base stock, the consumption of this colour chemistry hardwood pulp is 60-90% weight ratio, the consumption of this colour chemistry softwood pulp is 10-40% weight ratio.
Described wet-end chemicals comprises: softener, is food-grade long chain alkyl compound, and addition is 2-10 kg/ton paper; Wet strength agent is Polyamide Epoxy, and addition is 3-8 kg/ton paper; Aluminum sulfate, addition is 2-20 kg/ton paper.
Preferred scheme is: contain this colour chemistry hardwood pulp of weight ratio 70-80% and this colour chemistry softwood pulp of 20-30% in base stock; The addition of softener is 4-8 kg/ton paper, and the addition of Polyamide Epoxy is 3-5 kg/ton paper, and the addition of aluminum sulfate is 5-15 kg/ton paper.
Further preferred version one: this colour chemistry hardwood pulp containing weight ratio 80% in base stock, this colour chemistry softwood pulp of 20%, the addition of softener is 8 kg/ton paper, and the addition of Polyamide Epoxy is 4 kg/ton paper, and the addition of aluminum sulfate is 10 kg/ton paper.
Further preferred version two: this colour chemistry hardwood pulp containing weight ratio 70% in base stock, this colour chemistry softwood pulp of 30%, the addition of softener is 6 kg/ton paper, and the addition of Polyamide Epoxy is 3 kg/ton paper, and the addition of aluminum sulfate is 10 kg/ton paper.
Further preferred version three: this colour chemistry hardwood pulp containing weight ratio 90% in base stock, this colour chemistry softwood pulp of 10%, the addition of softener is 8 kg/ton paper, and the addition of Polyamide Epoxy is 5 kg/ton paper, and the addition of aluminum sulfate is 10 kg/ton paper.
Advantage applies of the present invention exists:
1, the true qualities wood pulp that the present invention uses is not bleached, is not added brightening agent, and the chemicals of interpolation is food grade materials, and the fruit preservative paper body paper produced meets the food-grade needs of fruit and vegetable packaging.
2, by using softener, addition 2-10 kg/ton paper, easily slides between paper fiber, and paper is soft and flexible, plasticity strengthens, and improves the packaging adaptability of fruit preservative paper.
3, by improving wet strength agent Polyamide Epoxy consumption, addition 3-8 kg/ton paper, the wet strength performance of paper has had large increase, pass through instrument test, paper reach 0.6 and more than 0.3kN/m respectively to wet tensile (strength) in length and breadth, solve the common fruit tin foil body paper moisture absorption meet wet after the problem of cracky.
4, by using aluminum sulfate, addition 2-20 kg/ton paper, can regulate pH value of paper between 5.5-6.5, the pH value of solutions of weak acidity and fruit and vegetable adapts, and is conducive to the storage of fruit and vegetable and fresh-keeping.
5, by the adjustment of wet end furnish, improve the physical indexs such as paper resistance toly to break, tears, deflection, improve back segment processing characteristics.After testing, the average bursting strength >=200kPa of fruit preservative paper body paper that the inventive method obtains, tearability >=400mN, effectively improves the accepted product percentage of end product, significantly reduces paper splintering problem in fruit and vegetable fresh-keeping process.
Detailed description of the invention
Below in conjunction with concrete enforcement, the present invention is described in further detail.The fruit preservative paper body paper quantification range that this patent is produced is 35-80gsm, fiber adopts this colour chemistry broad-leaved wood fiber 60-90%, seeds are Eucalyptus, poplar, Acacia etc., this colour chemistry needle-leaved wood fibre 10-40%, Southern Pine, the north pine, dragon spruce etc., defibrination Canadian freeness 300-500ml; Softener uses food-grade chain alkyl organic compound, and addition is 2-10 kg/ton paper, and wet strength agent Polyamide Epoxy addition is 3-8 kg/ton paper, and aluminum sulfate addition is 2-20 kg/ton paper.Base stock and wet-end chemicals all need to meet GB9685 " food containers, packaging material additive use sanitary standard " relevant regulations, and by food and medicine Surveillance Authority and the certification of European Food level security.
