Description
Technical field:
The present invention is relevant with packing chest that the color printing biaxially oriented polypropylene film is arranged and manufacture method thereof.
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 cost-cutting improves aesthetic property, gain in strength on traditional cardboard box printing is made, enlarge use and field 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 degree of automation and produced equipment, they are the make-up machine and the cardboard cutting off 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, 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 degree of automation 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 range of use 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, the demand of degree of finish out of reach 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 damp-proof performance of carton have also been increased simultaneously, also enlarged range of use, printed patterns on the cardboard and top layer, utilize plastic film coated adhesive 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 film layer or CPP film layer, also obtained to improve the decoration level really and improved that packing chest is worth and the effect of commodity value.
But if printed patterns is printed on the plastic film, particularly on the biaxially oriented polypropylene film, though pattern be imprinted on film outside face or in the surface, because the bright and clean and degree of saturation specific humidity of its printing-ink adds the degree of finish 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 printer 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 printer rolling printing biaxially oriented polypropylene film, again utilize dry compound machine coating adhesives such as aforesaid OPP film layer or CPP film layer after with the corrugated board that cut off compound by printed patterns and design customized cut-off it again, because of heating coated adhesive 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 adhesive 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.
Therefore color printing packing chest and the box compound after we pass through the coated adhesive 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 chest and box with the surface layer paper of packing chest.
Therefore in 03135247.2 patent of my application, invented a kind of behind the multicolour pattern that is beautifully printed on biaxially oriented polypropylene film or the Dampler Ace, it is compound on the fluting board packing surface layer paper, be compounded to form packaging boxboard with fluting board and nexine paper bonding again, cut edge then, slot and make packing chest, packing chest appearance three-dimension effect, stereovision are strong, be beautifully printed production efficiency height, simple equipments.But in this method, the film and the surface layer paper compound tense that have printed, uniform tension in order when the tension force of film will be with printing and rolling, prevent that as far as possible the film that is printed on pattern is elongated, compound temperature will be controlled well, prevent that film is elongated or shortens because of overheated, the paper of compound usefulness or film should can print with compound after the ageing treatment in the temperature and humidity environment of distortion minimum, the control difficulty is bigger, technological condition is grasped bad meeting and is caused the film and the compound back of surface layer paper that are printed on pattern to make printed patterns different in size because of the flexible of film, influencing the back cuts off, cut edge, the carrying out of fluting operation, the packing chest quality descends.
Summary of the invention:
The objective of the invention is for a kind of have three-dimension effect, stereovision, exquisite appearance and proof stress, the packing chest that the color printing biaxially oriented polypropylene film is arranged that lear energy is strong are provided.
Another object of the present invention provides a kind ofly carries out compound back with biaxially oriented polypropylene film or Dampler Ace and surface layer paper or fluting board and with printer film is carried out precision printing, is made into the manufacture method of packing chest again.
The purpose that the present invention is is achieved like this:
Packing chest of the present invention comprises packaging boxboard, packaging boxboard is by biaxially oriented polypropylene film and the surface layer that is compounded to form by adhesive layer and cardboard bonding, the outside face that it is characterized in that the biaxially oriented polypropylene film in the surface layer that bonding is compounded to form has the pattern printed layers of color printing, pattern printed layers has three-dimension effect at the outside face of film, degree of saturation specific humidity is arranged, has levels, increases fineness and sense 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.Biaxially oriented polypropylene film itself has the easily flexible defective of the temperature traverse of being subjected to, but anti-soak properties are fine, and cardboard is subjected to the temperature traverse stroke very little, but anti-soak properties are very poor, become a kind of synthetic material after the two compound one, again at the outside face printed patterns of film, enter the carrying out that the back cuts off, cuts edge, slots, makes the packing chest operation no matter be, still deposit, the pattern position that outside face prints can remain unchanged lastingly temporarily, has guaranteed packing chest contoured surface quality attractive in appearance.
Also has nexine in the above-mentioned packaging boxboard, the enhancement layer that has one deck corrugation shape cardboard at least to make between surface layer and the innermost layer.
The innermost layer 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 in the innermost layer, surface layer and innermost layer have all that the cardboard of packing chest 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 chest 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 chest, 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 is at the outside face of biaxially oriented polypropylene film, the polypropylene of biaxial tension is not if add inorganic filler or add inorganic filler less such as calcium carbonate, titanium dioxide, its stretching caudacoria has better diaphaneity, and film is brighter and cleaner.
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 outside face of film, in film, add inorganic filler calcium carbonate, titanium dioxide, when film is carried out biaxial tension, poly-mer 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 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, but the pattern that on film, prints various finenesses that at high speed is done soon, 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.
