Abstract
The present invention provides a film permeating, code printing and mark making method of a laser device used on film coated product package, which comprises technical processes of product package, film coating, laser code printing and mark making, etc. The present invention is characterized in that after a film is coated outside a product package body material, laser radiation is carried out by the laser device so as to make the surface of a packaging material and the inner wall of an outer coated film form the same or corresponding character codes or patterns. A printed packaging material counterfeited by other people is avoided. So far, the method of the present invention is a making method with economical and social benefits and anti-counterfeit identification, and the method can be actually used in a high speed flow-line production process.
Description
The invention provides a kind ofly in the packing of product, coat earlier, use laser equipment to carry out the method for film sign marking then with film.
Laser is beaten yard technology with characteristics such as its high speed, low consumption, environmental protections, be specially adapted to the high speed flow production line, on packings such as food, beverage, drinks, daily necessities, electronic product, can manufacture contents such as date, lot number, sequence number, bar code, model, pattern.The type of slave unit lasing light emitter has CO
2Gas laser, Nd:YAG solid statelaser etc.The mode of operation of slave unit is divided, and has diaphragm type (Mask) laser to beat that code system marking device, dot matrix (Dot Matrix) laser are beaten the code system marking device, continuous wave formula (Continue Wave) laser is beaten code system marking device etc.Coating materials such as printing paper, tin graphed sheet are arranged from related packing, and plastics, glass, metal etc.Laser code printing method in the past is directly to beat the code system mark on the surface of above-mentioned material, this is a kind of traditional application process, the effect of package anti-counterfeiting is considered at this method end, and therefore character code or the pattern of making of orthodox method very easily simulated with the method for printing, machine up.From actual situation of China, along with the development of commodity economy, need be a kind of reliable, practical, in the packing of product, make the method for anti-counterfeiting mark.
The present invention aims to provide and a kind ofly carries out the method for film sign marking with laser equipment, reaches the false proof purpose of the packing of product.
The present invention uses high-tech equipment, and the intrinsic high efficiency of performance laser equipment, high reliability, low cost, characteristics such as pollution-free realize online making anti-counterfeiting mark in the packing of product.
The present invention includes: with packing the bulk material packaging product, in the packing of product, coat film, use laser to beat the technological process that the code system marking device carries out the laser irradiation, it is characterized in that after coating film on the packing of product bulk material, carry out the laser irradiation with laser equipment, make material (as greasepaint, the seal China ink etc.) evaporation of packing the bulk material outside face be coated to the outer inwall that covers film, form and pack bulk material surface corresponding or identical character code or pattern fully thereby cover the film inwall outside.
Concrete grammar of the present invention and step are:
1, adopt common packing method, with packing bulk material product is packed;
2, outside packaged product, carry out film and coat;
3, adopt laser equipment, the integral packaging behind the coating film is carried out the laser irradiation, thereby make the outside face of packing and the inside face of coating film all obtain cooresponding required character code or pattern.
Packing bulk material of the present invention can be printing paper, tin graphed sheet etc., and the material outside requiring its outside face to have evaporate under laser irradiation to be coated on the coating film is as greasepaint, print China ink etc.Can be only this type of material be arranged beating code system mark position.
Membraneous material of the present invention must have the laser-transmissible energy.Be that membraneous material should not absorb laser fully, otherwise will cause packing bulk material surface can not produce character code or pattern.Membraneous material can be PE, BOPP etc.The method that film coats can be thermal contraction, vacuumize or other method etc.After requiring to coat film, the spacing between film and the packing bulk material is as far as possible little, preferably less than 0.5 millimeter.
The laser energy that the present invention adopts can produce character code or pattern clearly, can not produce the sealing property of destroying, influence film again simultaneously and be advisable to film.Laser energy wants the performance of combination film material type, thickness and packing bulk material surface mass to be adjusted to suitable numerical value.The energy of its lasing light emitter is no more than 5 joules, 0.5-5 joule the best.
Beat code system target content, by the mode of operation and the customer requirements decision of device therefor.
The character code or the pattern that adopt the present invention to make before not sealing off the film that covers outside the packing, do not need by any utensil, can see its content clear, intuitively.When taking film apart, mobile a little film, promptly can find: character code or pattern that the film inwall forms because of coating are fully corresponding or identical because of character code or the pattern that the laser irradiation produces with packing bulk material outside face.Evaporate because of material at packing bulk material outside face, and expose under the situation of material background color, during mobile film, can find that laser plays character code or pattern that the code system mark is given birth to,, expose the material background color and produce a kind of color change because of film moves.
Use method provided by the invention, carry out laser and beat sign indicating number or system mark in the packing of product, make packing of product outside face and coat the film inside face all to have character code or pattern one to one simultaneously, this is that other any method all can't be accomplished.Use this method, given full play to the characteristics that laser is beaten the code system marking device, realized the purpose of online making anti-counterfeiting mark.When having avoided using other method for anti-counterfeit, because of packing, anti-fake material out of control in operation process, perhaps because of anti-fake material multi-source, the easy counterfeit drawback that produces.The method of the invention is up to now, can be actually used in the high-speed flow line production process, the anti-counterfeiting mark method for making of tool economic benefit and social benefit.
Embodiment 1
In the perfumed soap production process, after perfumed soap packed with printing paper or box (packing bulk material),,, make it tightly to be coated on outside the wrapper with heat shrink process with polyethylene (PE) film.Select to have on the packaging the position of printing greasepaint, use diaphragm type laser equipment (making the trade mark and the date manufactured of customer requirement on the matrix in advance), see through the PE film, carry out the laser irradiation, can obtain required trade mark and date manufactured at wrapper outside face and film inwall.
Embodiment 2
In the cigarette production process, finish carton (packing bulk material) packing, after the thermal contraction of BOPP film coats operation, use dot matrix laser equipment (in equipment, importing pictorial trademark and product batch number that customer requirement is made in advance), be chosen in the position that greasepaint is arranged on the wrapper, see through the BOPP film and make trade mark and lot number.
Claims (6)
1, a kind of laser equipment that uses on product overlay film packing carries out the method for film sign marking, comprise that the packing of product, film coat, laser is beaten technological processes such as code system mark, it is characterized in that product being packed with packing bulk material, can evaporate when this packing bulk material surface has the laser irradiation and be coated to the outer material that covers on the film, after outside packing of product bulk material, coating film, see through film with laser and shine and pack the bulk material surface, make packing bulk material surface and cover film inwall generation correspondence or identical word or pattern outward.
