Abstract
The invention provides a method for manufacturing a package from a plastic sheet and belongs to the technical field of the packaging technology. According to the method, the problem that patterns are difficultly printed on packages in the prior art is solved. The method includes the steps that firstly, a projection drawing of a printing pattern to be shown on a finished package on a raw plastic sheet is designed; secondly, the projection drawing is printed on the plastic sheet; thirdly, the face, on which the pattern is printed, of the plastic sheet is covered with gloss oil; fourthly, the plastic sheet is heated and softened, and the plastic sheet is formed through a die under the blistering or blow molding technology; and fifthly, redundant parts on the plasticized package are cut off, and the finished package is obtained. According to the method for manufacturing the package from the plastic sheet, the deformed pattern is printed on the plastic sheet in advance, and then the pattern recovers to the normal state along with deformation of the plastic sheet; and the pattern is convenient to print, disengagement is avoided, and printing does not need to be conducted on an uneven finished product.
Description
Technical field
The invention belongs to packing technique field, relate to a kind of preparation method of packaging, particularly a kind of plastic sheet makes the method for packaging.
Background technology
Plastics package utilizes plastic uptake technique or blow molding process mainly through thermoforming technology, after plastic sheet thermoplastic, utilize positive pressure air or negative pressure air softened plastic sheet is expanded and is adjacent to the mould intracavity wall of mould, form blow-molded article or the Blister product with multiple concaveconvex shape.
In order to increase the attractive in appearance of packaging, usual needs impressing pattern on the packaging, the production method of traditional thermal-formation products of plastic sheet material just prints pattern or word in product thermoforming, but because blowing or Blister product become multiple rough shape, common typography cannot complete, printed patterns and word easily wear and tear, come off, and pollute the food of institute's splendid attire.In addition pattern is printed on a kind of thinner plastic sheeting, then by compounding machine coating binder, transparent or the opaque plastic sheet that in compound, other one deck is thicker, obtain two-layer composite plastic sheet, packaging product is made in thermoforming again, because compound tense employs adhesive and chemical solvent dilutes, so add the residual content of chemical solvent in thermoforming plastic sheet-material package goods, and reduce production efficiency, significantly add production cost.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of method that plastic sheet makes packaging, this method can produce the packaging product with impressing pattern fast.
Object of the present invention realizes by following technical proposal: comprise the steps:
Step one: design the perspective view of printed patterns on feed material plastics sheet material that packed products will present, can utilize existing Computer Aided Graphic Design software to generate easily;
Step 2: perspective view is printed on plastic sheet;
Step 3: print on figuratum at plastic sheet and cover oil polish, to form diaphragm;
Step 4: thermoplastic is carried out to plastic sheet, recycling mould makes plastic sheet shaping under plastic uptake or blow molding process;
Step 5: the redundance in the packaging after excision plasticity, obtains packed products.
Make in the method for packaging at above-mentioned plastic sheet, die cavity is arrange side by side multiple, on plastic sheet, stamping the many group perspective view corresponding with die location during step 2, stamping the photoelectricity distinguishing mark corresponding with often organizing perspective view at plastic sheet edge simultaneously; Plastic sheet is transmitted between each operation by conveyer, and photoelectric recognizer detects the position by pattern on photoelectricity distinguishing mark determination plastic sheet; When step 3, after on a picture group case is corresponding with die cavity position, when namely detecting that photoelectricity distinguishing mark moves to correct position, the die cavity of arrangement carries out moulding to the plastic sheet at this picture group case place simultaneously, after this retable shape completes, mobile plastic sheet, then carry out moulding to the plastic sheet at next picture group case place.Can carry out moulding to plastic sheet in batches like this.
Make in the method for packaging at above-mentioned plastic sheet, the photoelectricity distinguishing mark printed is Quick Response Code, the pattern-information that the corresponding plastic sheet of Quick Response Code is printed, it is not merely the positional information of plastic sheet, as the size of dyestuff material during impressing pattern or pattern, subject matter etc., so that subsequent handling adopts different process conditions to process according to the character of pattern, such as, if the pattern printed is more complicated or the larger lines of area are thinner, the softening temperature of material is just improved when plastic working, slow down deformation process, being beneficial to pattern line along with material is slowly out of shape, be unlikely to occur fracture or deformity.
Make at above-mentioned plastic sheet in the method for packaging, the lines of described impressing pattern are dotted line line style, and the pattern line of the part that the shaping rear distortion of plastic sheet is larger is comparatively out of shape the lines tubbiness of smaller portions, line segment spacer is near.When plastic sheet plastic deformation, also can there is corresponding distortion in pattern, and the pattern line of projection can be stretched, thus make its lines return to policy state, pattern proportion coordinated attractive in appearance.
Make in the method for packaging at above-mentioned plastic sheet, the dyestuff of described impressing pattern is conductive paint or conductive ink, carries out utilizing magnetic field or the dyestuff heating of microwave to pattern to ensure its mobility in the process of plastic deformation to plastic sheet utilizing plastic uptake or blow molding process.
Make at above-mentioned plastic sheet in the method for packaging, before printing dyestuff, on plastic sheet, first produce the spill vestige of pattern, can utilize thermoprint, the modes such as engraving of diving, to produce the pattern line of depression, and then by filling fuels in spill vestige.Be conducive to the full of lines fuel like this, make lines can better with sheet material plastic deformation, not easy fracture.
Above-mentioned plastic sheet make packaging method in, described plastic sheet is high-temperature resistance plastice, sheet material can be heated to higher temperature, thus be conducive to fuel better follow sheet material stretching distortion.
Make at above-mentioned plastic sheet in the method for packaging, described plastic sheet is multi-layer compound structure, and whether the material of the number of plies and every layer is transparent can design according to product actual needs, and pattern can be printed and also can print in multilayer on individual layer.
Compared with prior art, the method for this plastic sheet making packaging has the following advantages:
1, the present invention adopts the pattern printing distortion in advance at plastic sheet, and the distortion along with plastic sheet makes pattern return to normal condition.Facilitate graphic-print, avoid departing from, need not print on rough finished product.
2, the present invention prints photoelectricity distinguishing mark while impressing pattern on plastic sheet, is conducive to the location to pattern on plastic sheet.
3, structure of the present invention is simple, and easy to operate, cost is low, can greatly enhance productivity.
