Abstract
The invention discloses food packing paper and a production method thereof. The production method comprises the following steps of: proportionally blending cotton wood chemical-mechanical pulp, bleached sulfate needle leaf wood pulp and bleached sulfate broadleaf wood pulp which serve as fiber raw materials, and forming the food packing paper through slurry screening, seasoning, slushing, desanding and degassing, sizing, fine screening, net part dehydration and forming, squeezing, pre-drying, surface sizing, post-drying, burnishing, reeling and packing. The food packing paper is treated by surface sizing; during surface sizing, starch surface sizing agent is added, so that the water-resisting property is enhanced; furthermore, a small amount of sizing agent alkyl ketene dipolymer is added into surface sizing solution, so that the retention rate can be increased, the cost is saved and the cost performance of the product is higher.
Description
Technical field
The present invention relates to packaging for foodstuff, particularly relate to a kind of used for packing foods paper and production method thereof.
Background technology
For a long time, plastic products are used in packaging for foodstuff in a large number, and owing to the difficult degradation of the plastics utmost point, plastic garbage intractable, food uses plastics package in a large number, easily causes the wasting of resources and environmental pollution, and plastic-food is for being one of the main source of present " white pollution ".Therefore, developed country launches respectively the plastics packed use of regulation limitations.For building " environmental friendliness, resources conservation " society, China forbids producing, selling and uying the super-thin plastic shopping bag from June 1st, 2008, and rules such as execution plastic shopping bag paid utilization system limit the use of plastic shopping bag.Food wrapper is mainly used in the substitute of food plastic bag; develop biodegradable food wrapper substituted for plastic packing, help building " amphitypy " society, become the theme of packaging industry development; help advancing energy-saving and emission-reduction, minimizing " white pollution ", preserve the ecological environment.
Chinese patent application numbers 200410050681.9 discloses a kind of cornstalk that utilizes and has made the method that non-chlorine bleaching pulp is produced food wrapper and cultural paper.With cornstalk or to remove the marrow cornstalk be raw material, boiling has used sulphur or sulphur urine to be that auxiliary agent, urea and NaOH are buffer with sulfite pulping.Bleaching is adopted the oxonium base extracting and is strengthened hydrogen peroxide and float.Product does not contain organic chloride and the acute dioxin carcinogen of disliking.But this method is raw material with the cornstalk, and digestant is an ammonium sulfite ammonium etc., is difficult to solve problem of environmental pollution in pulping process, and digestion time is long, and the energy consumption height becomes the paper physical strength poor, and the product applicability is not strong.
Chinese patent application numbers 200910043433.4 discloses food wrapper and production method thereof.Be raw material with timber through the DDS displacement cooking, wash sieve, oxygen delignification, hydrogen peroxide bleaching and make little the float slurry of whiteness, join and copy food wrapper at 22-36%.This product whiteness is low, and is of low grade, the scope of application of limits product.
Summary of the invention
Problem to be solved by this invention be on preceding technical foundation, provide a kind of and have higher-strength, meet the food wrapper of packaging for foodstuff hygienic requirements and lowly pollute, paper strength is good, whiteness is high, environmental friendliness, help the production method of comprehensive utilization of resources.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of food wrapper, it is characterized in that: make as fibrous raw material with poplar machine slurry, bleached sulphate softwood pulp and BRATSK, described ratio is 5-15% poplar machine slurry, bleached sulphate softwood pulp 20-25%, BRATSK 60%-70%, and major parameter is quantitative 50-80g/m
2, burst index 〉=2.0kPa.m
2/ g, tensile index 〉=35N.m/g, lead content≤5mg/kg, arsenic content≤1mg/kg, the Decolorant Test feminine gender can not detect salmonella, Shigella, staphylococcus aureus, and paper color is a white, whiteness 80-82%ISO.
For obtaining above-mentioned packaging for foodstuff paper product, production method of the present invention comprises following content: starch with the poplar machine, bleached sulphate softwood pulp and BRATSK are made fibrous raw material, its ratio is a 5-15% poplar machine slurry, bleached sulphate softwood pulp 20-25%, BRATSK 60%-70%, wherein poplar machine slurry adopts the PRC-APMP pulping process to make with the aspen fibers by using silicon raw material, the whiteness 75-78%ISO of slurry, the bleached sulphate softwood pulp, BRATSK is pulled an oar respectively, beating consistency 3.5-4.5%, bleached sulphate softwood pulp and BRATSK beating degree are respectively 36-40 SR and 30-34SR; After three kinds of slurries are joined slurry in proportion, through underflow sieve, condiment, dash slurry, desanding degasification, starching, fine screen, wet end dewater moulding, squeezing, preceding drying, top sizing, after drying, press polish, batch, packing forms food wrapper.
Starch surface glue agent concentration 8% in the described top sizing, resin added 4g/m
2, add alkyl ketene dimer in the sizing agent, alkyl ketene dimer consumption 10kg/ ton paper.
Be added with Fluorescence Quenching Agent in the plain boiled water of described wet end dehydration moulding.
Described joining adds when starching exhausted guar gum in slurry meter 0.1-0.5%.
It is that raw material is joined and copied wrapping paper that the present invention adopts high yield pulp, meets nation-building conservation-minded society and the relevant policies of developing a circular economy, and belongs to a kind of environmentally friendly machine.
The present invention uses the top sizing processing mode that product is handled, and interpolation starch surface jelly improves WATER RESISTANCE and a small amount of sizing agent alkyl ketene dimer is added in the top sizing glue in top sizing, can improve retention, save cost, make the product price ratio higher.
