Technical Field

The invention relates to the technical field of packaging bags, in particular to a packaging bag with a hidden two-dimensional code.

Background

In daily life, people constantly touch various packaging bags, and the types of the packaging bags are not limited in terms of shape, size, color, material, application and the like. And the lottery drawing two-dimensional code is arranged on the packaging bag, so that the packaging bag is an attractive sales promotion mode.

However, some existing products print two-dimensional codes in a visible area on an outer package, so that the two-dimensional codes are easy to steal; the setting in addition is in bag body middle part to hide the two-dimensional code through the cover of printing layer, before sweeping the sign indicating number, need reveal the printing layer of outside earlier, destroyed the integrality of the bag body, caused the wrapping bag to damage even.

Therefore, it is an urgent need to solve the problem of providing a safe and convenient-to-disassemble packaging bag with a hidden two-dimensional code.

Disclosure of Invention

In view of this, the invention provides a packaging bag with a hidden two-dimensional code, wherein the two-dimensional code is hidden inside a seal of the packaging bag, so that the phenomenon of brush stealing is avoided, the seal is convenient to disassemble, and the packaging bag is not damaged or the integrity of the two-dimensional code is not damaged.

In order to achieve the purpose, the invention adopts the following technical scheme:

a packaging bag with a hidden two-dimensional code comprises a bag body, wherein the bag body comprises a seal head and a bag body, and also comprises an inner coating layer and a heat sealing layer,

the two sides of the end socket in the vertical direction are folded inwards to form a triangular shape respectively, and then the two sides of the end socket in the horizontal direction are folded inwards to form a trapezoidal shape respectively for contact bonding; the two-dimensional code is arranged in the triangular area on one side and covered by the adjacent trapezoidal area; the inner coating layer is bonded on the triangular area on the other side and extends out of the trapezoidal area; the heat sealing layer is adhered and laid on the trapezoid-shaped area and the inner cladding layer extending out of the trapezoid-shaped area.

By adopting the scheme, the invention has the beneficial effects that:

the two-dimensional code is printed in the triangular area on one side formed by folding and covered by the adjacent trapezoidal area, when the two-dimensional code is scanned, the heat sealing layer needs to be uncovered firstly, and then the trapezoidal area of the seal is opened, so that the two-dimensional code can be exposed, the phenomenon of brush stealing is avoided, and the two-dimensional code cannot be damaged; the inner coating layer is bonded on the triangular area on the other side and extends out of the trapezoidal area, and when the heat sealing layer is uncovered, an uncovering point is easy to find, so that the seal is convenient to open, and the packaging bag is prevented from being damaged by improper operation.

Furthermore, the area where the two-dimensional code is located forms a square code scanning area, and four corner ends of the square code scanning area are connected with the seal head.

The beneficial effect that adopts above-mentioned further technical scheme to produce is that, the square yard district of sweeping only has four angle ends to be connected with the head, will sweep yard district complete disassembling easily, and then made things convenient for the scanning to the two-dimensional code.

Further, the triangle shape is an isosceles triangle shape, and the trapezoid shape is an isosceles trapezoid shape.

Further, the width of the end socket is 10-15 cm.

Furthermore, the inner cladding layer is made of non-woven fabric and is rectangular.

Further, the heat sealing layer is made of paper-plastic materials.
