Abstract

The utility model provides a composite anti-fakery paper board. One or a plurality of layers of inner cloth in a multi-layer paper board is/are regularly provided with anti-fakery safety line sets and any pulp layer is dyed a bright contrasting color. Line quantity, width and distance of the anti-fakery safety line set are selected within a certain range and the anti-fakery safety lines stuck to one pulp layer are galvanized metal lines in various colors with plastic film as the parent metal. Compared with the prior art, the utility model, due to the anti-fakery safety lines in a special rule and the visible contrasting color, highlights a structural change and thus is strong in anti-fakery feature, is easy to be identified by users and hard to be copied, protecting the benefits of the consumers and the operators.

Description

Composite anti-fakery paper board

Technical field

The utility model relates to the cardboard technical field, particularly a kind of Composite anti-fakery paper board.

Background technology

Existing antifake method for products is various, as laser sign, watermark, colored fibre and concavo-convex metal safety line etc.Some are to utilize printing or color photocopying method and as easy as rolling off a log counterfeit in these method for anti-counterfeit, as laser sign, colored fibre, bar code etc.; Some method for anti-counterfeit are as watermark, concavo-convex metal safety line, concavo-convex contact, cost costliness, be applied on bank note or the important ticket volume more, be used for the packing of product, because wrapping cal(l)iper is thicker, the antiforge function of watermark or concavo-convex metal safety line obviously reduces.

Recently in the couch board that occurs on the market, two-layer or multi-layer dyeing is as anti-counterfeiting mark at certain.Though the method can reach certain antifalse effect, but in paper-making process, dyeing is conventional process, special bottom and surface layer at cardboard, be very ripe production technology, in " papermaking and equipment " volume two 50-53 page or leaf of publication distribution in May nineteen eighty-two, doing to elaborate by light industry publishing house.Because dyestuff is bought easily, and dyestuff adding method is simple, form and aspect can accurately be imitated by common form and aspect instrument simultaneously.Therefore, no matter be multi-layer dyeing or certain two-layer dyeing, all be a kind of general paper technology, thereby copy easily that antifalsification is poor.

Summary of the invention

The Composite anti-fakery paper board that the purpose of this utility model is to provide a kind of and is suitable for the multilayer thick paper plate, be difficult to copy, antifalsification is strong.

The purpose of this utility model is achieved in that a kind of Composite anti-fakery paper board, have at least three coating layer and pulp layers, wherein one deck is a dye layer, is being provided with the plastic film layers that one deck at least is furnished with regular anti-fake safety line group between dope layer and the pulp layer or between the pulp layer.Described anti-fake safety line is to be the plated metal line of base material with the plastic sheeting.

The live width b=0.4 of described anti-fake safety line group～2mm, line-to-line is apart from L=(5-100) mm.The color of anti-fake safety line group is that monochrome or polychrome are alternate.

The anti-fake safety line group is made up of 5～20 safety lines, and every group of spacing distance is 20～200mm.Go to arrange the arranged mode of anti-fake safety line, the quantity of safety line group and the form and aspect of use metal wire according to the requirement of different user.

Safety line retable material thin layer both can add by individual layer, can also multilayer add.Safety line retable material thin layer adds at the compound place of ply of paper in the production process, and adds auxiliary binder in adding place and make safety line and the ply of paper can strong bonded.

According to the characteristic of safety line, it is the plated metal line of base material that the utility model adopts with the plastic sheeting, and its line is thick usually at 10-40 μ m, and is in light weight, and live width is usually at 0.4-2mm, and color clear changes various.This material heatproof, acid and alkali-resistance, slight stretch-proof.When waste paper recovery or waste disposal, safety line is handled through the hydraulic pulping rubbish rope of Waste Paper Handling or through the pressurized screen screening, is guaranteed its feature of environmental protection and cardboard reclaiming usability.

Combination board behind the adding safety line retable material thin layer, outward appearance with do not add the same of safety line, without any sags and crests or vestige, do not change the physical characteristic and the optical characteristics of cardboard, do not bring corrosion or dangerous composition yet, so just guaranteed the fineness printing and the back processability of product.

Beautiful in order ordinary consumer can successfully to be understood be familiar with its product of buying to have an anti-counterfeiting characteristic, in combination board, utilize the papermaking common process, dying at one deck arbitrarily has distinct contrast colot.

Compared with prior art, good effect of the present utility model is that antifalsification is strong, and easy to use, the consumer discerns easily, and the information that provides according to manufacturer is provided, and tears ply of paper, just can find easily and accurately identification.The structure of this anti-fake paper board is difficult to copy in paper industry, thereby consumer and operator's legitimate interests are effectively protected.

Description of drawings

By following embodiment the utility model is further elaborated.Wherein,

Fig. 1 is the utility model Composite anti-fakery paper board longitudinal cross-section schematic diagram.

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

Referring to Fig. 1, shown in Figure 2, a kind of Composite anti-fakery paper board of embodiment of the utility model is made up of eight coatings or pulp layer, comprises dope layer 1; Starch adhesive layer 2; Lining slurry layer 3;

Sandwich layer

4,5,6, one deck dyeing arbitrarily therein, present embodiment selects sandwich layer 6 to be dye layer; Anti-fake safety line retable material thin layer 7; Bottom pulp layer 8.In the view in transverse section of Fig. 2, demonstrate the cross section of layer 7 safety line retable material thin layer, each safe live width b=1mm wherein selects for use 5 safety lines to form, the distance L=20mm between two safety lines, it is the plated metal line of base material that safety line adopts with the PVC film, and its line is thick to be 20 μ m.Adopt red monochromatic alternate metal wire.Selecting layer 6 is the blue dyeing layer.

Claims

1, a kind of Composite anti-fakery paper board has at least three coating layer and pulp layers, and wherein one deck is a dye layer, it is characterized in that: be provided with the plastic film layers that one deck at least is furnished with regular anti-fake safety line group between dope layer and the pulp layer or between the pulp layer.
