Abstract
The invention discloses a KFC (Kentucky fried chicken) tray packing paper and a production method thereof. The KFC tray packing paper is characterized by being manufactured by adopting 25-35 percent of aspen chemi-mechanical pulp, 20-25 percent of bleached sulfate softwood pulp and 40-50 percent of bleached sulfate hardwood pulp as fibrous raw materials. According to the production method of the KFC tray packing paper, a surface sizing processing mode is initially used to process products, special surface sizing agents are added during surface sizing to improve the water resistance, and a small quantity of sizing agent AKD (alkyl ketene dimer) is added into a surface sizing glue solution, so the retention rate can be increased, the cost is saved and the cost performance of the products can be higher.
Description
Technical field
The present invention relates to a kind of KFC pallet packing paper and production method thereof, belong to the paper industry technical field.
Background technology
Late 1980s, KFC settles China Beijing and two tame international metropolis, Shanghai, and KFC has left the 400th tame shops in China in November, 2000.After this it has accelerated the paces of expansion, to success in 2007 interiorly except that Tibet more than 400 city in all provinces left tame shops more than 2000.Rate of expansion is the difference of Sino-U.S. two places shops of KFC management style behind, is the shop allied pattern in U.S. KFC, but in China, the Esaote SPA under KFC's brand is almost completely by oneself providing funds to build new shops.Chinese market has given KFC a golden opportunity.In the process of having a dinner of KFC, a dish is lined with one the one little pallet pad that chi is square, is lined with a pallet packing paper that is beautifully printed on the pallet pad.The general Food Packaging Paper that uses is made the pallet packing paper on the market, and this food paper is that little paper machine is produced mostly; Paper because equipment falls behind, all uses chemical pulp in process of production; Not only fibrous raw material consumes height, and pollutional load is serious, is unfavorable for building " amphitypy " society.On the other hand, because paper machine equipment falls behind, do not have the top sizing device, the specific aim of paper is not strong, and some performance indications is superfluous, and some index does not reach requirement, and printing is exquisite inadequately.
KFC's pallet packing paper has become a kind of food and has used the paper certain species, and the demand that help advancing energy-saving and emission-reduction, reduces protofibre is preserved the ecological environment.
One 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 adopts oxonium base extracting and reinforcement hydrogen peroxide to 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., in pulping process, is difficult to solve problem of environmental pollution, and digestion time is long, and energy consumption is high, becomes the paper physical strength poor, and the product applicability is not strong.
One 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 process little the float slurry of whiteness, join and copy KFC's pallet packing paper 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 better printability, meet food with KFC's pallet packing paper of hygienic requirements and low pollute, paper surface properties is good, whiteness is moderate, environmental friendliness, help the production method of comprehensive utilization of resources.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of KFC pallet packing paper; It is characterized in that: process as fibrous raw material with poplar machine slurry, bleached sulphate softwood pulp and BRATSK; Said ratio is 25-35% poplar machine slurry, bleached sulphate softwood pulp 20-25%, BRATSK 40%-50%, and major parameter is quantitative 60-80g/m
2, average in length and breadth fracture length>=2100m, lead content≤5mg/kg, arsenic content≤1mg/kg, Decolorant Test is negative, can not detect salmonella, Shigella, staphylococcus aureus, and paper color is a white, whiteness 80-82%ISO.
For obtaining above-mentioned KFC pallet packing paper product; Production method of the present invention comprises following content: make fibrous raw material with poplar machine slurry, bleached sulphate softwood pulp and BRATSK; Its ratio is 25-35% poplar machine slurry, bleached sulphate softwood pulp 20-25%, BRATSK 40%-50%; Wherein poplar machine slurry adopts the PRC-APMP pulping process to process with the aspen fibers by using silicon raw material, the whiteness 75-78%ISO of slurry, and bleached sulphate softwood pulp, BRATSK are pulled an oar respectively; Beating consistency 3.5-4.5%, bleached sulphate softwood pulp and BRATSK beating degree are respectively 36-40
0SR and 30-34
0SR; 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 KFC's pallet packing paper.
Starch surface glue agent concentration 10% in the said top sizing, resin added 4g/m
2, add AKD in the sizing agent, AKD consumption 10kg/ ton paper.
Be added with Fluorescence Quenching Agent in the plain boiled water of said wet end dehydration moulding.
Creativeness of the present invention is mainly initiated and adopted high yield pulp is that raw material is joined and copied wrapping paper, meets nation-building conservation-minded society and develops a circular economy relevant policies, belongs to a kind of environmentally friendly machine.
The present invention initiates and uses the top sizing processing mode that product is handled; And interpolation special surface sizing agent improves WATER RESISTANCE and a small amount of sizing agent AKD is added in the top sizing glue in top sizing; Can improve retention, practice thrift cost, make the product price ratio higher.
