Abstract

The utility model relates to a packaging box and provides a deshielding packaging box, which is a closed body comprising a box body, a box cover and a box bottom in mutual connection. The deshielding packaging box is characterized in that the box body, the box cover and the box bottom are made of composite boards, and each composite board comprises a protecting layer, a deshielding layer and a base layer from outside to inside in mutual composition. The packaging box is prepared by utilizing mirror ink to completely or partially replace dense aluminizing materials, and wireless microwave signals can be transmitted through tiny gaps among evaporated aluminum foils in the mirror ink, so that the problem of signal deshielding is solved, and attractiveness of an aluminized film packaging box is kept.

Description

Packing box deshields

Technical field

The utility model relates to a kind of packing box, relates in particular to the structure of deshielding at the bottom of box body, lid and the box of packing box.

Background technology

Technology is through the automatic recognition objective object of microwave radio signal and obtain related data for radio frequency identification (being called for short RFID), and identification work need not artificial the interference, can work in various environment, can discern a plurality of labels simultaneously, and is swift and convenient to operate.After 2004, the RFID technology obtains vigorous growth, and potentiality have a wide range of applications in fields such as warehouse logistics, product false proof, products in circulation and product maintenance trackings.

But the RFID label runs into some difficult problems on using, especially under the environment that metal mask or interference are arranged, because of its basic physical characteristic limits, cause the RFID label normally to use.

At present, be the packing box of base material with the paperboard of aluminizing, holographic card paper etc. on the market, because of having characteristics such as attractive in appearance, good weatherability, it is widely used, especially in fields such as food and drink, medicine, health products, cosmetics, gifts.But the aluminium coated owing to aluminize on the paperboard or the holographic card paper of aluminizing is made up of the metallic aluminum material of densification; Just in box, form a complete shielding system after processing packing box; Make wireless microwave signal to penetrate and to feed back; This with regard to serious limit the RFID The Application of Technology, the RFID technology can't be applied to these package interior, makes the RFID broad application be restricted.

The utility model content

The purpose of the utility model is to provide a kind of packing box that deshields, to overcome the above-mentioned defective that prior art exists.

The described packing box that deshields of the utility model is for by interconnecting the obturator that constitutes at the bottom of box body, lid and the box; It is characterized in that, be composite panel at the bottom of box body, lid and the box, from outside to inside, is made up of each other compound protective cover, deshield layer and basic unit;

The material of protective cover is the PET film, and the material of basic unit is a paper material; The layer that deshields is ink with mirror effect, can be formed by the typography coating;

The performance of said ink with mirror effect and preparation method; In patent CN201010514067.9 and patent CN200910129597.9, detailed description is arranged, it is pulverized the back by the vapor deposition aluminium foil and forms with mixed with resin, be printed on polyester film surface after; The excellent gloss that it has, alternative metallized film.

Because ink with mirror effect is to be mixed by vapor deposition aluminium foil and binding resin, layered arrangement and have small space between the aluminium foil, this just makes wireless microwave signal therefrom to see through, and does not form screening effect.

Can know by above disclosed technical scheme; Ink with mirror effect is all or part of to replace the fine and close material of aluminizing to prepare packing box to the utility model through using; Utilize that the micro gap between the vapor deposition aluminium foil sees through wireless microwave signal in the ink with mirror effect; Both solve the signal shielding problem, kept the attractive in appearance of aluminizer packing box again.

The specific embodiment

Referring to Fig. 1 and Fig. 2, the described packing box that deshields of the utility model is for by 3 interconnecting the obturator that constitutes at the bottom of box body 1, lid 2 and the box; It is characterized in that 3 is composite panel at the bottom of box body 1, lid 2 and the box, from outside to inside, constitute by each other compound protective cover 4, deshield layer 5 and basic unit 6;

The material of protective cover 4 is the PET film, and the material of basic unit 6 is a paper material; The layer 5 that deshields is ink with mirror effect, can be formed by the typography coating;

Referring to Fig. 3 and Fig. 4, further, also comprise metallic dielectric layer 7, the said layer 5 that deshields is embedded in the metallic dielectric layer 7, and metallic dielectric layer 7 can adopt aluminium material, is prepared from the sputter aluminum plating process;

Further, the said layer 5 that deshields is circle, rectangle, triangle, ellipse, star or other geometric configuratioies.

Further, the cross sectional shape of the described packing box that deshields is circle, rectangle, triangle, ellipse, star or other geometric configuratioies.

Further, metallic dielectric layer 7 is 0.5～50 micron with the thickness of the layer 5 that deshields.
