Description

Packing plastic bag with antiforge test by itself and preparation method thereof

Technical field

The present invention relates to a kind of packing of product bag, especially packing plastic bag with antiforge test by itself and preparation method thereof with anti-false sign.

Background technology

Packaging bag on the market is multifarious, of a great variety at present.Manufacturer is the product of protection oneself, on normal packet pack basis, has adopted various false proof measures.Below be common several false proof measure:

Decals is known: paste anti-counterfeiting mark in packaging bag, low price, but increased the decals link influence production efficiency, and easily destroyed or fall to mark inadequately because of viscosity.

Two-dimensional bar code: include many product informations, but easily by imitated, and need use two-dimensional bar code recognizer (also being difficult to popularize) during check, inquiring about to the customer makes troubles.

The special ink technology: adopt anti-forgery inks such as fluorescence, temperature change, light change to print special character or pattern, effect is obvious; But the ink supply amount is too many on the market, be easy to obtain, to the counterfeiter provide may, and need use detecting instrument when detecting.

Digital technology: every bag of corresponding one group of number of product, this number contains many production informations of this bag product.The inquiry mode of digital technology has phone, online etc.But must make a mistake easily by the numeral of inputs such as phone or online when the customer inquires about, even also will produce enquiry fee usefulness.

Speckle interference, key anti-counterfeiting technology: can be produced on the carriers such as label, adhesive label, naked eyes see it is some unordered sites, when covering on it by certain orientation with relative check key, can see design-calculated literal or pattern, are convenient to identification; But because the check key is the film that is independent of carrier, not directly perceived, convenient when the identification authenticity of products, and increase productive costs.

Summary of the invention

One of purpose of the present invention provides and a kind ofly is difficult for imitatedly, detects simply, and does not need the packing plastic bag with antiforge test by itself checked by other instrument beyond the commodity.

Two of purpose of the present invention provides a kind of method for making of packing plastic bag with antiforge test by itself.

Concrete scheme of the present invention is: a kind of packing plastic bag with antiforge test by itself, comprise transparent plastic film, plastic gravure printing ink, it is characterized in that: be printed on burelage on the layer of transparent plastic sheeting therein, on another layer transparent plastic film, be printed on the key pattern supporting with shading, when shading and key were overlapping, the geometric centre of two patterns was overlapping; The key pattern area is greater than the burelage area; The pattern line of shading and key requires to have 5-10 bar line in 1mm.

The method for making of above-mentioned packing plastic bag with antiforge test by itself, carry out as follows:

A. design:

1. shading design: at first finish appearance profile, next draws the interior literal of outline or the profile of pattern, fills content at last; Should fill the zone between outline and literal or the pattern contour during filling earlier, the vertical element that is interrupted is only filled in this inside, zone; Recharge the zone in literal or the pattern contour, this inside, zone is also filled and is interrupted vertical element; The vertical element of being filled satisfies 5 lines in 1mm; And the vertical element between two zones keeps dislocation; Add rambling interference lines on the vertical element of in two zones, filling.

2. key design: at first finish the appearance profile identical with burelage, this contour area is directly filled vertical element then greater than the burelage area in outline, and satisfies 5-7 bar line is arranged in 1mm, in case other people find out at a glance;

B. set type: shading and key pattern should vertical or horizontal alignment, so that when superimposed, the geometric centre of shading and key pattern is overlapping;

C. electricity carving plate-making: with the designed pattern engraving on precision is gravure more than 150 lines;

D. printing: carry out chromaticity printing smaller or equal to the intaglio printing press of 0.12mm with overprint error;

E. moulding: the transparent plastic film after printed is introduced flanging machine, envelope cutter, carry out flanging, heat seal, cut, make the packaging bag finished product.

The present invention is when pattern that designs shading and key and literal, and best lines spacing is that 5 lines are arranged in 1mm; Key pattern outline is greater than burelage outline 2mm, to guarantee that key can overlap with shading.

Shading among the present invention is made up of rambling site, and design-calculated literal, pattern have in advance been implied in these sites, but naked eyes can't be differentiated.

Key among the present invention is the site that matches with shading.Its implication is that a kind of shading can only be with verifying with the supporting key of this shading.

Packaging bag of the present invention is that anti-counterfeiting technology and detection means are combined together with commodity dexterously, do not need to test by other instrument beyond the commodity, promptly check the anti-counterfeiting technology of commodity self with the anti-counterfeiting detection means of commodity self, thus the true and false of recognition value.Shading in packaging bag and key reconsul poststack can produce design-calculated encryption literal or pattern in advance.Shading and key pattern color can be with identical or different colors.When shading and key were used the ink printing of different colours respectively, poststack also can produce the third gorgeous color (when for example red shading and blue key are overlapping, can produce the purple pattern).

The present invention compared with prior art has the following advantages:

1. design difficulty height of the present invention, to plate-making precision and overprint error require high.The shading that detects by an unaided eye can only be seen some rambling sites, can not differentiate pattern and literal, promptly is to use state-of-the-art scanner scanning, also is difficult to duplicate, and this has just fundamentally stopped imitated.

2. detect simply, identification only needs burelage and key pattern overlapping are got final product easily, and is easy and simple to handle, do not need by other any testing tool or the means of adding, and is fit to very much public's anti-counterfeiting detection.

3. but anti-counterfeiting detection is carried out in packaging bag self of the present invention, and carries out the true and false and detect under the situation of not destroying packaging bag.
