Laser makes an application on complex flexible package

Tradition of the traditional flexible package that make a yard hits a means to bead of word of relief printing plate pressworks, continuous ink jet is printed, digital heat turns imprint etc, these means have an advantage each, but also put in a lot of inadequacy, hit a machine and Mo Lun in order to heat up carbolic belt to hit a machine to be exemple, both cannot be printed in real time, need hand uses newer date and batch number, make but sex of go against the river is restricted, and the LOGO that there is a standard in the process that print, bar code or rotate image, every printed character needs specific word bead. Proper warm-up time needs before the belt that heat up carbon hits a machine to operate, cooling time still needs when the change makes a news, this can extend manufacturing time undoubtedly, and once the discretion of word bead is done not have accurate right neat, can bring about the film that pack to happen wear broken. In addition, word bead wears away or lose still can make the result that print cannot be read take, and the length of the belt that heat up carbon is shorter also, the average length that homebred heat carbon takes is 100 meters only, make after giving out, need to change in time, appear in case leakage code; Mo Lun hits the ink marks of a machine to need certain and dry time, smear may arise below not complete and dry circumstance, affect the integral figure that pack, and smear still needs to use special and clean fluid to undertake cleanness. In addition, most Mo Lun hits a machine to make a machine with the belt that heat up carbon, warm-up needs before using, before changing the message that make a yard, need to cool. 2.

The working principle that laser lays a laser to make a yard is quantity of aux will be able to extremely tall laser gathers together, form the laser with bigger energy bundle, the object appearance that illuminate is made pile up to need, pass laser calcination or etch, make be hit to pile up material of object surface layer to produce aerification, implement dozen of code thereby. Stimulate the method of beam of light through control, can etch in object surface give an information of article wanting a picture, and the character that comes out by laser corrode score or design are quite careful, can make sure the position that make a yard is not had accurately more by accident. Laser hits a code to hit a machine to come true through laser, specific implementation process is shown 1 times like the graph. The infra-red laser that laser makes a code shoot bundle of diameter stricture by CO2 laser generation bundle, infra-red the illuminator that after stimulating beam of light to enter the head that print, moving with two sides encounters, this illuminator does scanning exercise along formulary contrail, pass lens will infra-red the material face that washs focusing of beam of light to make a yard to need, release very high energy at the same time, make material surface layer produces calcination, carry gas will residual blow off, form what what need to etch thereby design. Laser hits a code to be on complex flexible package most the form that often implements is to print 2 dimension code, number of serial of form code, date, product. Additional, its still have a very main use is to realize laser to tear off a line, application already succeeded on the complex flexible package in plating aluminous layer or other metal layer at present. The flexible package product that consumer buys in the market is for the most part common tear off a mouth, still have flexible package of a few provision, do not produce metamorphism to make sure food is inside goods shelves period, do the heal of the bag that pack very much tight, although the edge tears off buccal dotted line to rip, very laborious also, still can tear too suddenly forcibly the bag that pack, create very poor shopping experience. And use laser to hit a code to be able to be in any place of complex flexible package (it is place of heal of the bag that pack commonly) undertake lineation, rip very easily, and naked eye clarity is visible, implemented complex flexible package not only perfect the effect that rips easily, still can make lining film in good condition nondestructive, prevent effectively thereby inside outfit commodity sees light and be affected with damp be affected with damp. Current, laser tears off a line to had applied at medicines and chemical reagents, food, coffee (if the graph is shown 2 times) the complex flexible package that waits for commodity. The advantage 　 that laser of complex flexible package makes a yard 1.

Operate laser to hit a code to edit the relevant content that make a yard on computer directly easily, unlike tradition hits a need to tear open bead leaving a word to undertake adjustment, reduced labour cost. And the operation that laser makes a machine is very apt, the staff member can master operation method inside short time, begin is very easy. 2.

Hit a clarity, when paste of not easy hair uses the belt that heat up carbon to hit a means to undertake making a yard, complex flexible package is mixed easily in advancing process make a machine or clash produces between other and complex flexible package, cause paste of the hair that make a yard, other to complex flexible package even position causes pollution. Laser hits a code to use calcination corrode to cut a principle, make a yard more clear, won't produce above problem. 3.

The ruinous to block secondary floor small band that heat up carbon hits a code to use bulgy steel word to undertake turning imprinting, to hit a clarity, need brings to bear on constant pressure, appear easily partial position pressure is too great, press aluminum foil the case that wear, affect complex flexible package thereby cut off quality. Laser hits a code to implement dozen of code through controlling laser power, ensure to block secondary floor won't wait to cause any destruction to aluminum foil in the process that make a yard. 4.

After safeguarding cost low laser to hit a machine to throw, later period need not use the easy bad news such as the belt that heat up carbon, ink to taste, equipment is safeguarded more convenient, reduced greatly maintain cost. 5.

Successional strong, facilitating monitoring laser hits a code to control fixed length or be undertaken making a yard continuously according to color patch by computer, through taking a picture at the same time the system undertakes real time monitoring, can prevent leakage effectively to pile up circumstance happening. 6.

The effect that make a yard is permanent laser hits a code to use radiation of laser high energy to compound film surface layer, in its exterior ablation gives the character of need or design marks, because this laser label is had permanent with the extremely strong action that prevent bogus. And ink jet label adheres to through ink commonly in material surface, time grows, may be ground. 7.

Environmental protection laser hits a code not to use the easy bad news such as the ink jet ink, belt that heat up carbon to taste, won't produce the grain substance such as dirt then, do not have radiation, free from contamination to the environment. 8.

Efficiency tall laser hits a code to have online, high speed, without idle characteristic, manufacturing efficiency is tall, can realize successive trends to make a yard. The defect 　 that laser of complex flexible package makes a yard 1.

Laser of complex flexible package makes gas of easy generation peculiar smell the code comes true through filmy to surface layer of complex flexible package calcination, because this is filmy,the meeting after classics calcination produces relatively pungent gas. Although this kind of problem cannot avoid, but flexible package company still can try to improve through other measure, for instance my company carries the kind that to laser the place that make a yard has airtight convulsions filters, solved this problem well. 2.

Suitable scope is finite and current, laser makes a yard general the complex flexible package that more ground uses at containing aluminum foil and plating aluminous material, aluminium regards block as secondary floor, can protect its effectively in-house and filmy material and inside outfit product is insusceptible, and the application on the complex flexible package that its are not containing aluminum foil material or monolayer film flexible package still suffers be restricted. The note 　 that laser of complex flexible package makes a yard 1.

Presswork the impression that make a yard makes code and the effect distinction that make a yard on aluminum foil directly on the filmy material with transparent surface layer not quite apparent, the definition of the content that print is not quite high also, if pursue,3 are shown. So, the message of article of the graph that make a yard that goes up to highlight complex flexible package further, need to hit a place to presswork in laser an impression, general with brunet give priority to. 2.

Notice the circumstance with sordid calcination to go up because of complex flexible package sometimes the printing ink of use a few special color or printing ink system, in its laser makes the case with occurrence sordid calcination of the meeting in piling up a process (like the graph 4 are shown) , imprint in filmy watch especially when undertaking laser makes a yard on the layer, more need to note this kind of problem. To this, can consider to hit a position to change in corresponding laser printing ink of other facial expression or printing ink system. 3.

In tooth form knife the laser on hot sealing side hits a code to use tooth form knife when complex flexible package when heat is sealed, because of the reason of cutting tool or composite material, stuff of surface layer film because be heated can happen with aluminum foil layer statified, when laser calcination, statified because place does not have aluminum foil to deliver quantity of heat in time, the appearance that creates profit of out of round of brim of graph article message easily (show 5 times like the graph) , especially the style with more stroke, appear more easily the circumstance of the see things in a blur that make a yard. To this, need to solve complex flexible package to heat seals storied problem or change laser to call a position mainly. 4.

Because different and filmy stuff is right,the laser with different qualitative capable person makes a yard of laser energy absorb degree to differ, the difficult easy level that because this differs,filmy material hits the implementation when the code in laser also somewhat difference. Among them, the difficulty when PE film laser makes a yard is the greatest, when undertaking laser makes a yard on the compound film that is PE film when outer layer, can create the situation of the embellish of out of round of the brim that make a yard, see things in a blur that make a yard. Current, laser hits a code to already got more and more extensive attention in the application of industry of domestic and international flexible package, all sorts of new-style systems that make a yard emerge in endlessly, and replacing the traditional pattern that make a yard with its distinct advantage. Make the ceaseless promotion of a technology as laser, and the development that flexible package diversification, high speed changes, laser hits a code to be sure to be able to replace the traditional pattern that make a yard in great quantities, produce the energy with new infuse to flexible package.
