Description
Technical field:
The present invention and color printing biaxially oriented polypropylene film and the compounded packing case of corrugated paper and manufacture method thereof are relevant.
Background technology:
Packed in cases is the packing that all commodity all be unable to do without, in order to improve the value of commodity, upward century-old messengers for the raising aesthetic property that reduces cost, gain in strength on traditional cardboard box printing is made, enlarge use and range of application and raise the efficiency, carried out many research and improvement.
In the printing making of traditional full paper corrugation case, form the higher complete set of automaticity and produced equipment, they are the make-up machine and the cardboard cutting machine of multilayer corrugation shape cardboard, the sheet-fed press of carton surface layer paper and cardboard or paper roll continuous printing, the corrugated board Paper-pasting machine, the corrugated board printing slotting machine, carton is stuck with paste case (box) machine or is ordered punch-out equipment.
General system case production process is that paper roll prints continuously, on the make-up machine of corrugation shape cardboard, couch board is shaped to corrugation shape to increase paper board strength, breaking amylan simultaneously fits corrugated multilayer and couch board, paste with the paper roll of continuous printing at the same time and form the cardboard that there is the corrugation shape enhancing of printed patterns on the top layer, after this corrugated board is cut to the size of specification specifies by cardboard, putting into the corrugated board printing slotting machine slots (here because of top layer rolling printing to its otch by the carton specification, do not republish, if there is not the rolling printing, corrugated board is printing top layer pattern on this machine just).Corrugated board behind the otch fluting is stuck with paste the carton of binding for stipulating on punch-out equipment or the box press at carton.
At present traditional carton is all produced like this, just equipment size and automaticity different, and the progress of printing press can be produced various cartons faster, more easily, improves the printing aesthetic property and the maximization of carton.But traditional carton scope of application is very limited, and such as the packing of chilled food, marine product, fruits and vegetables, because carton is non-moistureproof, uses at freezer and have to carton is come with waxdip moistureproof, causes the carton cost too high and be subjected to promoting restriction.In the printing on carton top layer and the continuous printing of coil paper, because the thickness deviation of corrugated board surface too big and coil paper is too coarse, not bright and clean, lackluster, the fineness and the gloss of printing, fineness does not reach the demand of commodity, people bring into use the cast polypropylene film now, polyester film, biaxially oriented polypropylene film removes the printed patterns on carton top layer of the cardboard of compound one by one or topped above-mentioned cut-out after its surface is coated with a layer binder with coating method, make more gloss of printed patterns, bright and clean and attractive in appearance, the intensity and the moistureproof performance of carton have also been increased simultaneously, also enlarged the scope of application, printed patterns on the cardboard and top layer, utilize plastic foil coated binding agent will be one by one cardboard and top layer compound or topped mainly be to have utilized existing conventional equipment and technology such as OPP laminating machine or CPP laminating machine, also obtained to improve the decoration level really and improved that packing case is worth and the effect of commodity value.
But if printed patterns is printed on the plastic foil, particularly on the biaxially oriented polypropylene film, though pattern be imprinted on film outer surface or in the surface, because the bright and clean and saturation degree of its printing-ink adds the fineness of film and the refraction action of film, undoubtedly can be more exquisite than the printing on paper, rich merchant's product value more, but if utilize the printing machine of existing carton to print biaxially oriented polypropylene film one by one, because film has stronger electrostatic interaction, can't print at all and chromatography accurate, if with existing plastic gravure machine or flexible flange printing machine rolling printing biaxially oriented polypropylene film, again utilize dry compound machine coating adhesives such as aforesaid OPP laminating machine or CPP laminating machine after with the corrugated board that cut off compound by printed patterns and design customized cut-off it again, because of heating coated binding agent, film has necessarily and elongates or shortens, and the strictness that has influence on printed patterns repeats and is different in size, if with the printed patterns on the film is that fixed length might produce different in size compound to irregular with the corrugated board that is cut to fixed length at heating coated binding agent because of aforesaid film, film has serious electrostatic influence in addition, more difficultly when composition operation, align with cardboard, the otch fluting of back cardboard more can't accurately be located, 8 flangings of carton and 6 faces all can't be alignd with the design code printed patterns, the printed patterns of each face is interfered with each other.
If biaxially oriented polypropylene film with above-mentioned rolling printing, rolling is continuous when utilizing dry compound machine coating adhesives such as aforesaid OPP laminating machine or CPP laminating machine and the corrugated board of cut-out is compound, also still can because of cause film to have to film heating coated binding agent necessarily to elongate or shorten the strictness that has influence on printed patterns repeats and different in size so with the corrugated board that is cut to fixed length can't be accurately compound and cut film surely, if reduce heating-up temperature printed patterns is not is not elongated or shortened as possible, though possible ordinary production but reduce combined efficiency greatly and thereby the speed cost raises is uneconomical.
Therefore color printing packing case and the box compound after we pass through the coated binding agent still seeing the pattern that is beautifully printed as possible on the surface layer paper at corrugated board in advance on the market with the biaxial stretching film of layer of transparent or casting films so far with cardboard surface layer paper, and can't obtain behind the pattern that is beautifully printed on biaxially oriented polypropylene film or the Dampler Ace compound and make packing case and box with the surface layer paper of packing case.
Summary of the invention:
The objective of the invention is for a kind of biaxially oriented polypropylene film and compounded packing case of corrugated paper that third dimension, stereovision, exquisite appearance and proof stress, color printing that lear energy is strong are arranged is provided.
Another object of the present invention provides a kind of behind the multicolour pattern that is beautifully printed on biaxially oriented polypropylene film or the Dampler Ace, it is compound on corrugated paper packing case and the box face again and becomes a reality the biaxial tension gathering propylene film of color printing and the manufacture method of the compounded packing case of corrugated paper.
The object of the present invention is achieved like this:
Packing case of the present invention comprises packaging boxboard, packaging boxboard is the surface layer that is compounded to form by biaxially oriented polypropylene film and the cardboard by resin bed and biaxially oriented polypropylene film bonding, nexine, the enhancement layer that the corrugation of one deck at least shape cardboard between surface layer and nexine is made constitutes, it is characterized in that the outer surface of biaxially oriented polypropylene film and/or in the surface pattern printed layers of color printing is arranged, pattern printed layers has third dimension at the outer surface of film, saturation degree is arranged, have levels, increase sense exquisite and in kind, this situation uses the Dampler Ace printing best, because of film is the pearly-lustre film, be paper white, cardboard can be used the reclaimed materials cardboard.Pattern printed layers in film the surface, pattern is more glossy, bright and clean, can not frayed, durable and more meet hygienic requirements, this situation is generally used the transparent polypropylene film; If the surface printing background color is white such as porcelain in hyaline membrane, silver grey, golden, outer surface printed patterns at film, can obtain more special printing effect, if adopting traditional printing process prints earlier and then topped layer of transparent film in paperboard surface, just necessarily do not adopt the color printing effect of this printing, biaxially oriented polypropylene film itself has not proof stress, defective such as easily tear, but have than the better printing performance of other film after particularly being treated to pearlescent synthetic paper after the sided corona treatment, compound with cardboard again, proof stress, the performance of tear-proof also is improved, become a kind of synthetic material, they have had higher intensity.
The nexine of above-mentioned packaging boxboard is that biaxially oriented polypropylene film and cardboard are compounded to form by resin-bonded, and biaxially oriented polypropylene film is at nexine, surface layer and nexine have all that the cardboard of packing case has the cardboard than conventional carton that higher bearing capacity is arranged behind the biaxially oriented polypropylene film, it is high by 30%～50% that packing case is piled high comparable conventional boxes, the protection against the tide of cardboard, waterproof ability improves greatly, solved the packing storage difficult problem of frozen goods, if also color printing pattern on the nexine polypropylene screen, can improve its commercial value, improve the manufacture difficulty of packing case, useful false proof, make the compound color printing layer of this layer at nexine, its method is the forming method of surface layer roughly the same also.
The biaxially oriented polypropylene film of above-mentioned packaging boxboard surface layer is transparent single-layer membrane structure; the pattern printed layers of color printing the outer surface of biaxially oriented polypropylene film and/or in the surface; the polypropylene of biaxial tension is not if add inorganic filler or add inorganic filler such as calcium carbonate less; titanium dioxide; its stretching caudacoria has better transparency; film is brighter and cleaner; if will be in film the surface printing pattern; the effect that must use hyaline membrane could give prominence to printed patterns; but use hyaline membrane can protect printed patterns not frayed; pattern is because of the anaclasis effect of the film more gloss that seems; bright and clean; more gorgeous, can increase the commercial value of case.
The biaxially oriented polypropylene film of above-mentioned packaging boxboard is the pearly-lustre film that contains the imitative paper of inorganic filler single layer structure, the film surface is that the periphery of nuclear has the micropore because of the biaxial tension formation of film with the inorganic filler, the pattern printed layers of color printing is at the outer surface of film, in film, add inorganic filler calcium carbonate, titanium dioxide, when film is carried out biaxial tension, polymer in the film is stretched, but with the inorganic filler is that the periphery of examining can produce a lot of micropores, add with corona sided corona treatment is carried out on the film surface, film surface can produce a large amount of coarse concavo-convex, in conjunction with micropore, film has just obtained the printing performance of paper, the pattern that on film, prints various finenesses that can do soon fast, printing quality and efficient have all improved, this film adds that the dispersion refraction action of titanium dioxide makes paper be pearly-lustre white, because of producing a large amount of micropores, the proportion of film has also reduced, the proportion of film is generally below 0.8, we claim that this film is the synthetic iridescent paper of polypropylene, certain this film also can be made coloured pearly-lustre film, hyaline membrane has been saved material relatively, obtained the printing performance of paper, improved intensity with the compound back of cardboard, also, film itself is paper white because of having the property of covering, can make background color by white art paper with the cardboard that film is compound, can be with general paper, even the cardboard that can make with recovery paper, therefore adopt this pearly-lustre film that is paper white that is added with the biaxial tension of inorganic filler, and with hyaline membrane economical with materials cost more.
The biaxially oriented polypropylene film of above-mentioned packaging boxboard is the pearly-lustre film of the imitative paper of trilamellar membrane structure, all add inorganic filler in every tunic respectively, the film surface is that the periphery of nuclear has the micropore because of the biaxial tension formation of film with the inorganic filler, the pattern printed layers of color printing is at the outer surface of film, as after adding inorganic filler and biaxial tension, forming micropore in the aforementioned films, sided corona treatment has had the printing performance of paper in addition, but still has film strength, improve the intensity of packing case with cardboard after compound and enlarged purposes, we are referred to as synthetic paper, this film is a kind of good material, above-mentioned individual layer pearly-lustre film is some defective still, cause is a monofilm, restriction because of drawing process, the inorganic filler ratio that adds can not be high, after high, the one, easy rupture of membranes makes the qualification rate of film not high during the monofilm biaxial stretching film, therefore it is difficult to produce the following film of 20 μ m, the 2nd, insufficient because of adding inorganic filler, though the goods proportion after the stretching is lower than hyaline membrane, but more than 0.75, the single-layer membrane structure inorganic filler easily is exposed to face in addition, the powder that easily falls during printing also influences printing quality and efficient, for more low-gravity is arranged, there is thinner pearly-lustre film on packing case, to use and reduces the cost of this packing case, we have adopted the Biaxially oriented polypropylene pearly-lustre film of trilamellar membrane structure, adopt this film, can add the inorganic filler of more ratios in the intermediate layer, and two surface layers add the small amounts of inorganic filler as long as the micropore after satisfying stretching adds concavo-convex after the corona processing and can satisfy printing performance, after having guaranteed printing performance like this, can be because of the adding of a large amount of inorganic matters in intermediate layer, the back pearly-lustre film that stretches can have and is lower than 0.7 proportion, economical with materials more, three-layer co-extruded biaxial tension simultaneously also can obtain the pearly-lustre film below 30 μ m to the 20 μ m, more exquisite with the printing of this pearly-lustre film, efficient is also high, material cost is lower, increases the power of striving unexpectedly of packing case.
The manufacture method of packing case of the present invention may further comprise the steps:
A. the polypropylene screen of the biaxial tension of rolling or polypropylene pearlescent synthetic paper are carried out sided corona treatment with corona treatment plant to one side at least or prepare when the system film sided corona treatment and print surface tension force at the polypropylene screen of the biaxial tension of 35N/m～50N/m;
