Abstract
The invention discloses a high-tearing-strength transparent packing paper processing method and a packing paper product. The method comprises the following steps of: selecting a polypropylene film and single-layer paper; sizing two surfaces of the polypropylene film; clamping the polypropylene film between the upper single-layer paper and the lower single-layer paper; compounding the upper single-layer paper and the lower single-layer paper by adopting an upper and lower double-roller squeezing mode, drying the rear section by hot air and reeling to keep the paper neat and flat and avoid turnup edges; and squeezing a compounding region by the upper and lower rollers and controlling pressure of a pressing region to be 100 to 120 kN/m, wherein the drying curve temperature of the rear section is 150 to 180 DEG C and water content of a drying region is controlled to be 9 to 15 percent of the total mass, so that the packing paper product made by compounding the upper single-layer paper, the lower single-layer paper and the polypropylene film clamped between the upper single-layer paper and the lower single-layer paper is obtained. The invention has the advantages that: 1, the packing paper manufactured by adopting the method is semitransparent, so that indistinct cubic patterns can be seen, and the packing paper has quite high artistic quality; 2, the packing paper has high intensity and high tearing strength and anti-aging property; and a handbag made of the packing paper can bear weights of more than 10 kilograms; 3, the paper placement surface in a natural state is stiff and smooth and free of warpage; and 4, a product printed by using the packing paper has clear patterns and bright colors.
Description
Technical field
The present invention relates to light industry paper conversion industry, i.e. a kind of manufacture method of novel high tearing-strength transparent packing paper.
Background technology
The material that can be used as wrapping paper is a lot, and can satisfy folding has type, printing color gorgeous, has again some strength and can effectively protect the packaging material of content to be only the preferred packaging material.At present, the packaging bag with transparent feel mostly is plastic membrane product, can only carry out the oiliness printing, and printed matter has penetrating odor, and the packaging bag moulding is not well-pressed.Although and the pure plant fiber wrapping paper of same thickness is attractive in appearance, the packaging bag disrepair phenomenon usually appears in intensity difference, and is not fully up to expectations.
The high tearing-strength transparent packing paper shape that is translucent appears dim three-dimensional pattern, has aesthetic; Its anti tear, ageing resistace excellence, the handbag of making can carry the above weight of 10Kg.Nature placement page surface is well-pressed, without warpage, is fit to very much various mode of printings, especially the water-based printing pattern is also very exquisite, and well-known, water-based printing belongs to environmental printing, the nonirritant peculiar smell can be widely used in the packing of the products such as food, medicine, daily light industry, cigarette.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of technique simple, the processing method of a kind of high tearing-strength transparent packing paper that production cost is low and wrapping paper product thereof.
For achieving the above object, technical scheme of the present invention is: described production method comprises the following steps:

2, tensile strength (vertically) 〉=1kN/m, the single-part stationery of smoothness 〉=100S;
B, two-sided applying glue on described polypropylene film, resin added 0.5 ~ 3 g/m
2, then sandwiched polypropylene film in the middle of the two-layer single-part stationery in up and down, adopt the two roller fashion of extrusion in up and down compound, and the back segment heated-air drying is batched and is kept smooth without alice;
C, two roller extrusion claddings district, up and down control nip pressure 100 ~ 120kN/m; 150 ~ 180 ℃ of back segment drying curve temperature are controlled out baking zone moisture with respect to 9 ~ 15% of gross mass.
Described polypropylene film adopts the two-sided applying glue of membrane type transfer method or impregnated applying glue; Described sizing agent is styrene-acrylonitrile copolymer acids latex.
Described sizing agent is the mixed liquor of starch or polyvinyl alcohol or starch and polyvinyl alcohol.
In the two roller fashion of extrusion in described up and down, wherein decorative pattern is carved with on the surface of top roll.
The wrapping paper product that a kind of production method of high tearing-strength transparent packing paper is as mentioned above produced, it is by sandwiched polypropylene film in the middle of the two-layer single-part stationery in up and down and form through compound, its quantitative 70 ~ 90 g/m2, tensile strength (vertically, laterally) 〉=10kN/m, tearability (vertically, laterally) 〉=500 mN, transparency 〉=60%; Smoothness 〉=100S.
Adopt the wrapping paper of technique scheme processing, the shape that is translucent appears dim three-dimensional pattern, has aesthetic; Its anti tear, ageing resistace excellence, the handbag of making can carry the above weight of 10Kg.Nature placement page surface is well-pressed, without warpage, is fit to very much various mode of printings, especially the water-based printing pattern is also very exquisite, and well-known, water-based printing belongs to environmental printing, the nonirritant peculiar smell can be widely used in the packing of the products such as food, medicine, daily light industry, cigarette.
Advantage of the present invention is: 1, adopt the wrapping paper of the inventive method manufacturing shape that is translucent, appear dim three-dimensional pattern, have aesthetic; 2, intensity is high, anti tear, ageing resistace excellence, and the handbag of making can carry the above weight of 10Kg; 3, nature placement page surface is well-pressed, without warpage; 4, the printed matter clear patterns, bright in luster.
