Description

Anti-counterfeit packing bag and its processing technology

Technical field

The present invention relates to a kind of processing technique of packaging bag, and in particular to a kind of Anti-counterfeit packing bag and its processing technology.

Background technology

Plastic packaging bag is existing frequently-used food pack.For convenience to the identification and monitoring of product, often exist Security code will be stamped when printing packaging bag.But, when processing and packing bag, packaging bag manufacturer is supplied to product The packaging bag of product manufacturer have some be storage it is standby be not to use immediately.Upper product is specifically packed in the packaging bag of this part Time do not know, therefore also cannot just determine the time for competiton of product.So, generally operation is in present industry, packs Bag manufacturer, by printing good pattern and security code packaging bag be supplied to specific goods producer, by goods producer according to In the actual date of production of product, again spraying is carried out in packaging bag with flush coater and print the date of production i.e. date of manufacture.

But, because each manufacturer is not the packaging bag manufacturer of specialty.They print date of manufacture compared with Carry out very good correction.Some bad businessmans can modify after it's the shelf-life pasts goods to the date of manufacture and again spraying is printed. These expired products are continued as new product to sell, this greatly compromises the interests of consumer.

But, equally can be to consumer if allowing packaging bag manufacturer to be printed upon the date of manufacture in packaging bag at the very start Make troubles.Manufacturer is in order to stop product processing time below, it is possible to packaging bag manufacturer can be allowed to beat in packaging bag One time point for comparing rearward of print, and actual product pack will be in advance than this date of manufacture for printing when dispatching from the factory.Institute With, either consider from the interests of consumer, or from facilitating from the point of view of manufacturer's operation, packaging bag is all preferably by product Manufacturer oneself carries out spraying printing according to the actual production time of product.But, bad manufacturer is prevented again or is sold Correction of the business to packaging bag.Therefore, it is badly in need of developing now and a kind of is prevented from secondary modification and with preferable anti-counterfeiting performance Anti-counterfeit packing bag.

The content of the invention

The invention is intended to provide a kind of Anti-counterfeit packing bag, easily altered and weighed to solve the date of manufacture in existing packaging bag The new problem for printing.

Scheme one：Anti-counterfeit packing bag in this programme, includes successively being close to the food product layer of food from inside to outside, for fuel feeding The printable layer of ink print anti-fake mark, for covering printable layer the isolation layer that printable layer is contacted with the external world is intercepted, and is covered in isolation Soda acid layer on layer and it is covered on soda acid layer for the extexine on print production date；The isolation layer, soda acid layer and appearance Layer is transparent film layer；And the soda acid layer scribbles faintly acid transparency material near the one side of isolation layer, the soda acid layer is close The one side of extexine scribbles alkalescence transparency material；The extexine is provided with the through hole that regularly arranged naked eyes can not be looked into.

Operation principle and beneficial effect：

Food product layer separates with printable layer, and food product layer contact food, Main Function is to load protection food.Printable layer is mainly used To bear the labelling of ink, can be avoided directly on printable layer to anti-fake mark with ink fake marker on printable layer Modify.Printable layer is isolated with soda acid layer by isolation layer, it is to avoid printable layer reacts and affect printable layer with soda acid layer On anti-fake mark.Soda acid layer is faintly acid transparency material near the one side of isolation layer, even if isolation layer is broken, faintly acid is transparent Material also will not react with the ink of same slant acidity, will not produce larger shadow to the anti-fake mark generated with ink print Ring.The outer surface of soda acid layer againsts extexine.Extexine is the outermost layer of whole packaging bag, and printing can be sprayed on extexine Date of manufacture.Because soda acid layer is scribbled between alkalescence transparency material, and soda acid layer and extexine in the one side of extexine The through hole connection on extexine can be passed through.So, if if the ink that spraying is printed upon on extexine touches through hole, meeting React with the alkaline transparency material on soda acid layer through through hole, make the shape ratio that this part is printed there is no the position of through hole Put slightly a lot.The date of manufacture for entirely spraying printing again clearly can be found out by consumer.And manufacturer oneself Date of manufacture printing is carried out in the appearance layer segment without through hole, is waited and do not have in this section to enter where through hole again after ink setting Row punching.Because ink drying, the alkaline transparency material that will not be then passed through through hole and the inside reacts.And because bag Include and have printed the date of manufacture through hole is all distributed with interior all extexines so as to which other people are enterprising in the original date of manufacture in time Row is altered, and the ink for newly gushing out equally can react through through hole with the alkalescence transparency material on soda acid layer, cause this The numeral that part is printed just can be noted abnormalities by consumer at a glance than thick many elsewhere.Effectively prevent in packaging The modification date of manufacture of spraying again on bag, not only the false proof of product is accomplished by anti-fake mark, moreover it is possible to by changing Date of manufacture accomplished the false proof of date of manufacture.

The characteristics of present invention is using ink slant acidity, prints reach through hole on the extexine of date of manufacture, in appearance in spraying Scribble on soda acid layer inside layer can alkalescence transparency material, the ink that sprays again is sent out with alkalescence material through through hole Raw reaction, causes the numeral for spraying printing the uneven situation of line weight occur.In the case where people can not see through hole, The through hole number and position that each word for the date of manufacture that reviser is printed is touched can be different, and these are produced to make printing The ink on date can be presented thickness inequality after with the reaction of alkalescence transparency material, and suddenly big or suddenly small situation allows consumer at a glance Can just find out that this date of manufacture is irregular, improve the vigilant psychology of consumer.Solve the problems, such as the secondary modification of packaging bag.Have Effect is avoided to be changed the date of manufacture again, and expired product is again flowed into into the disgusting conduct in market.It is why transparent with faintly acid Material and alkalescence transparency material, are because comparing highly acid material and strong alkaline substance, react more gentle more preferable control, and It is more stable in the normal state, will not make troubles to the use of packaging bag.

Scheme two：Further, the faintly acid transparency material is carbon acid solution.

Carbonic acid is weak acid, will not be reacted with the ink of same slant acidity.And carbonic acid can be inhaled automatically when temperature is too high Receive heat and resolve into water and carbon dioxide, food can be lowered the temperature, for the Conservation environment that food provides suitable temperature.

Scheme three：Further, the alkalescence transparency material is sodium bicarbonate solution.

Sodium bicarbonate solution is in alkalescence, and can neutralize bicarbonate with the carbonic acid neutralization reaction of soda acid layer another side Hydroxyl in sodium solution so as to regenerate sodium bicarbonate.So, even if breaking between soda acid layer, a layer of carbonic acid is scribbled Also sodium bicarbonate solution can be neutralized, it is to avoid it passes through brokenly the isolation layer for falling to react with the ink on printable layer.With carbonic acid one Sample, sodium bicarbonate also can absorb heat and be changed into sodium carbonate and water when temperature is high, can inhale when outside environment is too high The temperature that heat is received for packaging bag surrounding is lowered the temperature, and is conducive to providing the temperature environment for being easy to preserve for food.

Scheme four：Further, the through hole is uniformly distributed in extexine in netted.

It is netted to be uniformly distributed, it is convenient that through hole is processed, it is also possible to which that each part for making packaging bag is covered with through hole, increase Plus the contact area of alkalescence transparency material and ink, it is to avoid spray ink again carries out secondary painting on outer top layer to packaging bag Change.

Scheme five：Further, it is provided with anti-pseudopore at date of manufacture position on the extexine.

When manufacturer prints the date of manufacture, because know the distributing position of through hole, therefore these through holes can be avoided carry out Date print；After date print is complete and dry, acanthopore is carried out where not scribbling between these dates as anti-pseudopore； When other people can be made to distort the date of manufacture of expired product, because not knowing the distributing position of specific anti-pseudopore, therefore distort Date of manufacture can be such that the alkalescence material contacted with extexine by through hole occurs with ink because printing to the position of anti-pseudopore Reaction, makes whole date printed become lines uneven.Consumer is allowed to find out that this date is through altering at a glance.

Another object of the present invention is to provide a kind of processing technology of Anti-counterfeit packing bag, is comprised the following steps：

Step one：Anti-forgery ink is allocated, the parts by weight of anti-forgery ink formula each component are：The false proof powder 6, polyamine of UV Fat varnish 53-57, EA water 23-26, isopropanol 16-22, auxiliary agent 7, toner 1.8-2.2；

Step 2：It is printed on the machine, the print product pattern labelling in printing layer；

Step 3：Isolation layer and food product layer are pressed onto successively the two sides of printable layer with hot press；

Step 4：Soda acid layer binding agent is pasted onto on isolation layer at 4-6 DEG C；

Step 5：Extexine is directly extruded at 4-6 DEG C and is pasted onto on soda acid layer；

Step 6：Hole is got through on extexine；

Step 7：The date of manufacture is printed on extexine on the position without through hole；

Step 8：Date ink to be produced is killed, and on date of manufacture position anti-pseudopore is punctured.

The Anti-counterfeit packing bag made using this technique can not only quickly recognize packaging bag from the pattern of printing The true and false, moreover it is possible to effectively prevent personator from directly altering the behavior of date of manufacture.

Description of the drawings

Fig. 1 is the structural representation of the embodiment of the present invention.

Specific embodiment

Below by specific embodiment, the present invention is further detailed explanation：

Reference in Figure of description includes：Food product layer 1, printable layer 2, isolation layer 3, soda acid layer 4, extexine 5.

As shown in Figure 1：Anti-counterfeit packing bag in the present invention, including including successively being close to the food product layer 1 of food from inside to outside, With the printable layer 2 for being used for ink fake marker, for covering printable layer 2 isolation that printable layer 2 is contacted with the external world is intercepted Layer 3, the soda acid layer 4 being covered on isolation layer 3 and is covered on soda acid layer 4 extexine 5 for the print production date.

Isolation layer 3, soda acid layer 4 and extexine 5 are transparent film layer；And soda acid layer 4 scribble near the one side of isolation layer 3 it is weak Acid transparency material, faintly acid transparency material is carbon acid solution.Carbonic acid is weak acid, will not be occurred with the ink of same slant acidity anti- Should.And carbonic acid meeting automatic absorption heat when temperature is too high resolves into water and carbon dioxide, and food can be lowered the temperature, and is food Thing provides the Conservation environment of suitable temperature.Soda acid layer 4 scribbles alkalescence transparency material near the one side of extexine 5；Alkalescence is saturating Bright material is sodium bicarbonate solution.

Sodium bicarbonate solution is in alkalescence, and can neutralize bicarbonate with the carbonic acid neutralization reaction of the another side of soda acid layer 4 Hydroxyl in sodium solution so as to regenerate sodium bicarbonate.So, even if breaking between soda acid layer 4, a layer of carbonic acid is scribbled Also sodium bicarbonate solution can be neutralized, it is to avoid it passes through brokenly the isolation layer 3 for falling to react with the ink on printable layer 2.With carbonic acid Equally, sodium bicarbonate also can absorb heat and be changed into sodium carbonate and water when temperature is high, can when outside environment is too high, The temperature for absorbing heat for packaging bag surrounding is lowered the temperature, and is conducive to providing the temperature environment for being easy to preserve for food.

Extexine 5 is provided with the through hole that regularly arranged naked eyes can not be looked into.Through hole is uniformly distributed in extexine 5 in netted.

It is netted to be uniformly distributed, it is convenient that through hole is processed, it is also possible to which that each part for making packaging bag is covered with through hole, increase Plus the contact area of alkalescence transparency material and ink, it is to avoid again spraying ink carries out secondary on outer top layer 5 to packaging bag Alter.

Anti- pseudopore is provided with extexine 5 at date of manufacture position.

When manufacturer prints the date of manufacture, because know the distributing position of through hole, therefore these through holes can be avoided carry out Date print；After date print is complete and dry, acanthopore is carried out where not scribbling between these dates as anti-pseudopore； When other people can be made to distort the date of manufacture of expired product, because not knowing the distributing position of specific anti-pseudopore, therefore distort Date of manufacture can be such that the alkalescence material contacted with extexine 5 by through hole sends out with ink because printing to the position of anti-pseudopore Raw reaction, makes whole date printed become lines uneven.Consumer is allowed to find out that this date is through altering at a glance.

The processing technology of Anti-counterfeit packing bag, comprises the following steps：

Step one：Anti-forgery ink is allocated, the parts by weight of anti-forgery ink formula each component are：The false proof powder 6, polyamine of UV Fat varnish 53-57, EA water 23-26, isopropanol 16-22, auxiliary agent 7, toner 1.8-2.2；

Can make the pattern for printing or word that there is the effect for reflecting motley light with this anti-forgery ink, Can make one to be clear that.

Step 2：It is printed on the machine, the print product pattern labelling in printing layer.

Step 3：Isolation layer 3 and food product layer 1 are pressed onto into successively the two sides of printable layer 2 with hot press；

Step 4：Soda acid layer 4 is pasted onto on isolation layer 3 with binding agent at 4-6 DEG C；

Step 5：Extexine 5 is directly extruded at 4-6 DEG C and is pasted onto on soda acid layer 4；

Step 6：Hole is got through on extexine 5；

Step 7：The date of manufacture is printed on the position without through hole on extexine 5；

Step 8：Date ink to be produced is killed, and on date of manufacture position anti-pseudopore is punctured.

Embodiment 1 as shown in table 1 is built respectively to embodiment 3 according to above-mentioned processing technology and its different parameter values.

Table 1

With existing processing technology according to the formula same with corresponding embodiment, comparative example 1 to 3 is built respectively；With existing False proof processing technology and its corresponding false proof formula, as a comparison case 4.By embodiment 1 to embodiment 3 and comparative example 1 to right The packaging bag that ratio 4 is produced, prints identical patterns, and phase same date is checked respectively to 100 people, then with identical maneuver pair Each packaging bag carries out date of manufacture correction, then the packaging bag after correction is given again into 100 people of identical and is checked. Obtain result as shown in table 2.

Table 2

From table 2 it can be seen that same printing formula is respectively adopted, but the different comparative example 1 of processing technology is to comparative example 3 Contrast one by one to embodiment 3 with embodiment 1, comparative example 1 to comparative example 3 and embodiment 1 to embodiment 3 because be identical Anti-forgery ink formula, so the antifalse effect of the security pattern of printing is almost the same.But it is because comparative example 1 to comparative example 3 It is different to the processing technology of embodiment 3 from embodiment 1, cause after the date of manufacture alters, the vestige of correction be not it is obvious that Unless carefully identification, it is impossible to find out that it has been altered.Therefore, though using identical anti-forgery ink, not using the present invention's Processing technology, does not have the function of preventing the date of manufacture from being altered yet.

And comparative example 4, compared with embodiment 1 to embodiment 3, identical anti-forgery ink was not both adopted, also do not adopt Identical processing technology, its security pattern is compared to the security pattern in embodiment 3 in embodiment 1, and its reflective color is single, distinguishes Knowledge and magnanimity are relatively low.And after the date of manufacture is altered, comparative example 4 can not clearly distinguish the date of manufacture altered and be not coated with The difference of the date of manufacture for changing, the anti-altering function for not possessing the date of manufacture.Therefore, not using the present invention anti-forgery ink and The packaging bag that fabrication process goes out, antifalse effect is poor, does not possess the effect for preventing the date of manufacture from being altered.

Food product layer of the present invention 1 separates with printable layer 2, and the contact food of food product layer 1, Main Function is to load protection food.Beat Print layer 2 is mainly used to bear the labelling of ink, can be avoided directly in printable layer with ink fake marker on printable layer 2 Anti-fake mark is modified on 2.Printable layer 2 is isolated with soda acid layer 4 by isolation layer 3, it is to avoid printable layer 2 and 4, soda acid layer Life is reacted and affects the anti-fake mark on printable layer 2.Soda acid layer 4 is faintly acid transparency material near the one side of isolation layer 3, even if Isolation layer 3 breaks, and faintly acid transparency material also will not react with the ink of same slant acidity, will not be to being given birth to ink print Into anti-fake mark produce considerable influence.The outer surface of soda acid layer 4 againsts extexine 5.Extexine 5 is the outermost of whole packaging bag Layer, can spray the printing date of manufacture on extexine 5.Because it is saturating that soda acid layer 4 scribbles alkalescence in the one side of extexine 5 Can be connected by the through hole on extexine 5 between bright material, and soda acid layer 4 and extexine 5.So, if spraying is printed upon If the ink on extexine 5 touches through hole, can react with the alkaline transparency material on soda acid layer 4 through through hole, make The shape ratio that this part is printed does not have the position of through hole slightly a lot.Make the date of manufacture for entirely spraying printing again can be very Significantly found out by consumer.And manufacturer oneself carries out date of manufacture printing in the part of extexine 5 without through hole, oil is waited Do not have in this section again to be punched where through hole after ink drying.Because ink drying, through hole and inner will not be then passed through The alkaline transparency material in face reacts.And because be all distributed with including all extexines 5 that have printed including the date of manufacture Through hole so as to which other people are altered in time on the original date of manufacture, the ink for newly gushing out equally can be through through hole and acid Alkalescence transparency material on alkali layer 4 reacts, and the numeral ratio for causing this part to be printed is thick many elsewhere, at a glance Just can be noted abnormalities by consumer.The modification date of manufacture of spraying again in packaging bag is effectively prevent, not only by false proof Labelling has accomplished the false proof of product, moreover it is possible to accomplished the false proof of date of manufacture by the date of manufacture that can not be changed.

The characteristics of present invention is using ink slant acidity, prints reach through hole on the extexine 5 of date of manufacture, in appearance in spraying Scribble on the soda acid layer 4 of the inside of layer 5 can alkalescence transparency material, make the ink that sprays again can be through through hole and alkalescence material React, cause the numeral for spraying printing the uneven situation of line weight occur.The situation of through hole is can not see in people Under, the through hole number and position that each word of the date of manufacture that reviser is printed is touched can be different, make printing these The ink of date of manufacture can be presented that thickness is uneven after with the reaction of alkalescence transparency material, suddenly big or suddenly small situation, allow consumer Can find out that this date of manufacture is irregular at a glance, improve the vigilant psychology of consumer.Solve asking for the secondary modification of packaging bag Topic.Effectively prevent and change the date of manufacture again, expired product is again flowed into into the disgusting conduct in market.Why faintly acid is used Transparency material and alkalescence transparency material, are because comparing highly acid material and strong alkaline substance, react more gentle more preferable control System, and it is more stable in the normal state, will not make troubles to the use of packaging bag.

Above-described is only embodiments of the invention, and the general knowledge here such as known concrete structure and characteristic is not made in scheme Excessive description.It should be pointed out that for a person skilled in the art, on the premise of without departing from present configuration, can be with Some deformations and improvement are made, these should also be considered as protection scope of the present invention, these are implemented all without the impact present invention Effect and practical applicability.This application claims protection domain should be defined by the content of its claim, in description Specific embodiment etc. records the content that can be used for explaining claim.
