Description

The packing box that the biaxially oriented polypropylene film of color printing and cardboard are composited

Technical field:

The utility model is relevant with packing box, and especially the packing box that is composited with the biaxially oriented polypropylene film and the cardboard of color printing is 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 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.

General system case production process is that paper roll prints continuously, 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 cardboard 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 also to obtain to improve the decoration level really and improve that packing chest is worth and the effect of commodity value such as OPP film layer or CPP film layer.

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, it is compound with the cardboard that cuts off to utilize open type compounding machines such as aforesaid OPP film layer or CPP film layer to be coated with the bonding back again 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 cardboard 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.

If biaxially oriented polypropylene film with above-mentioned rolling printing, rolling is continuous when utilizing dry compound machine coating adhesives such as aforesaid OPP film layer or CPP film layer and the cardboard of cut-out is compound, also still can because of cause film to have to film heating coated adhesive 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 with the compound fancy packing box of 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 box after we pass through the coated adhesive agent still seeing the pattern that is beautifully printed as possible on the surface layer at cardboard in advance on the market with the biaxial stretching film of layer of transparent or casting films so far with the surface layer paper of packing chest.

The utility model content:

The purpose of this utility model is in order to overcome above deficiency, provides a kind of three-dimension effect, stereovision strong, the biaxially oriented polypropylene film of proof stress, color printing that lear energy is strong and the packing box that cardboard is composited.

The purpose of this utility model is achieved like this:

The packing box that the biaxially oriented polypropylene film of the utility model color printing and cardboard are composited, comprise biaxially oriented polypropylene film and by resin bed and the compound cardboard of biaxially oriented polypropylene film, the outside face of biaxially oriented polypropylene film and/or inside face have 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.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, easily defective such as tears, but have than the better printing performance of other film after particularly being treated to pearlescent synthetic paper after the corona treatment, compound with cardboard again, the performance of proof stress, anti tear also is improved, and becomes a kind of synthetic material, and they have had higher intensity.Can utilize that printed patterns is imprinted in the hyaline membrane back, surface is compound with paper, it is wear-resisting that this packing box is used for requirement film smooth surface more, protection printed patterns and hygienic requirements is arranged.

Above-mentioned biaxially oriented polypropylene film is transparent single-layer membrane structure; the printed patterns of color printing is at the outside face or the inside face of 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; 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 can increase the commercial value of case because of the refraction of light effect of the film more gloss, bright and clean, more gorgeous that seems.

Above-mentioned biaxially oriented polypropylene film is to be the individual layer pearly-lustre film that the imitative paper of paper white has inorganic filler, the film surface is that the periphery of nuclear has the micropore that forms because of biaxial tension with the inorganic filler, the proportion of film is at 0.5～0.75, adopt the outside face of the printing pattern layer of seal at Biaxially oriented polypropylene pearly-lustre 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, but oil suction China ink in film surface has the good printing performance like paper, but the pattern that on film, prints various finenesses that at high speed is done soon, printing quality and efficient have all improved, because of the pearly-lustre film has a large amount of micropore pattern adhesion-tights, good covering property is arranged, can make composite bed without the expensive white copper coin paperboard of price, because of its proportion also lower than the proportion 0.90 of general biaxially oriented polypropylene film, can save membrane material, cost is also lower.

Above-mentioned biaxially oriented polypropylene film is that the coextrusion biaxial tension contains calcium carbonate and titanium oxide inorganic filler and interlayer is added with the pearly-lustre film of the trilamellar membrane structure that is paper white of the imitative paper of antistatic additive in addition, the film surface is that the periphery of nuclear has the micropore that forms because of the film biaxial tension with the inorganic filler, the proportion of film is at 0.5～0.75, the printing pattern layer of color printing is at the outside face of Biaxially oriented polypropylene pearly-lustre film, 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 be paper white, can make background color by white art paper with the cardboard that film is compound because of film itself has the property of covering, can be with general paper, even the cardboard that can make with recovery paper.
