Problems solved by technology

[0008] In order to increase attractiveness and people's enthusiasm for buying, manufacturers often hold lottery promotions and other activities. Plastic bottles can print graphic information (such as award-winning information) on the top surface of the bottle cap, but many flexible packaging bags have no caps and cannot be used. Similar method, and this method of printing graphic information on the top surface of the bottle cap, the internal material (especially liquid) is easy to contact with the ink of the graphic information, which may cause the problem of blurred graphic information, and the ink It will also pollute the material and affect the quality of the material, especially when the material is a quoted liquid, it will affect the health of the user

Embodiment 1

[0029] Such as figure 1 , 2 As shown, the flexible packaging bag with concealable information patterns in this embodiment includes a bag body 1 with a stretchable hem structure 2 disposed on the bottom surface of the bag body 1 . The flexible packaging bag is a self-supporting nozzle bag with a nozzle at the top.

[0030] Both the left end and the right end of the retractable hemming structure 2 of the bag body 1 have edge sealing 3 , and the outer surface of the hemming structure 2 is printed with a concealable information pattern, and the concealable information pattern is a two-dimensional code 4 . After the bag body 1 is filled with materials, the hemming structure 2 forms a triangular conical pit 5 at 3 places close to the two sealing edges, and the two-dimensional code 4 is located in the triangular conical pit on the left side of the hemming structure 2 5 on the inner wall.

[0031] The folded edge structure 2 is formed by connecting two folded edges 6, a part of the...

Embodiment 2

[0036] Such as image 3 , 4 As shown, the difference between this embodiment and the embodiment is:

[0037] The shape of the pit is a downwardly concave curved surface. The two-dimensional code 4 is completely located on the outer surface of one hem of the hem structure 2 .

[0038]The number of the retractable hem structure 2 is two, and the two hem structures 2 are respectively arranged on both sides of the bag body 1, the flexible packaging bag is an eight-side sealed bag, and there is no suction nozzle on the top of the bag body 1, There is a sealing edge 3 at the top of the folding structure 2 , and the two-dimensional code 4 is located in a triangular conical pit 5 close to the sealing edge 3 . The two-dimensional code 4 is completely located on the outer surface of a hem 6 of the hem structure 2. Since the outer surface of the hem 6 is distorted, the mobile phone cannot recognize it. Only the hem 3 is cut or torn, and then the The two-dimensional code 4 can only be...

Embodiment 3

[0041] Such as image 3 , 4 As shown, the difference between this embodiment and the embodiment is:

[0042] The number of the expandable hemming structures 2 is two, and the two hemming structures 2 are respectively arranged on both sides of the bag body 1, the flexible packaging bag is a penguin bag, and the top and bottom ends of the hemming structures 2 are All have edge sealing 3, and the hidden information pattern is located in the triangular conical pit 5 close to the edge sealing 3 at the top of the folding structure 2.

[0043] The concealable information pattern is graphic and text 7 that can be recognized by human eyes: winning information. Therefore, the graphics and text 7 that can be recognized by human eyes need to be as close as possible to the edge banding 3, and should be designed to be smaller or difficult to be recognized by human eyes.

[0044] Because many flexible packaging bags have a hemming structure 2 in their structural design, and one or both en...

Abstract

A flexible packaging bag with a concealable information pattern, comprising a bag body, the bag body has at least one stretchable hem structure, one end of the stretchable hem structure of the bag body has a sealing edge, and the outer edge of the hem structure The surface is printed with a concealable information pattern, and after the bag body is filled with materials, the folded edge structure forms a pit close to the edge seal, and the concealable information pattern is located on the inner side wall of the pit. A method for hiding graphic and text information on the surface of a flexible packaging bag. An edge sealing is provided at one end of a stretchable hemming structure of the flexible packaging bag, so that after the flexible packaging bag is filled with materials, the above-mentioned hemming structure is close to the edge sealing area A concave triangular conical pit is formed, and a concealable information pattern is arranged on the inner wall of the triangular conical pit, so that the concealable information pattern cannot be recognized by human eyes or mobile phones. A method of hiding graphic information. The invention can effectively ensure that the concealable information pattern can only be used after being sold.

Description

technical field [0001] The invention relates to a flexible packaging bag with a concealable information pattern and a method for hiding graphic information. Background technique [0002] Flexible packaging refers to packaging in which the shape of the container can change after filling or removing the contents. Various bags, boxes, sleeves, packages, etc. made of paper, aluminum foil, fiber, plastic film, and their composites belong to flexible packaging. [0003] There are two types of flexible packaging, namely stretch wrap packaging and various bags (i.e. flexible packaging bags). Stretch wrap consists of plastic film that has not yet been formed into the shape of the package, and is simply wrapped around the product or products to be packaged and held in place in some form. The flexible packaging bag is made into a certain shape before the product is put in or at the same time as the product is put in. Most commonly, the plastic sides are heat sealed to form this shap...
