Abstract

The invention discloses a packaging bag with a hidden two-dimensional code. The packaging bag comprises a bag body, wherein the bag body comprises a sealing head and a bag body, and further comprisesan inner coating layer and a heat sealing layer, wherein the sealing head is inwards folded along the two sides in the vertical direction to form a triangular shape, and then is inwards folded along the two sides in the horizontal direction of the sealing head to form a trapezoidal shape so as to be in contact and bonded; the two-dimensional code is arranged in the triangular area on one side andis 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; and the heat sealing layer is bonded and laid on the trapezoidal area and the inner coating layer extending out of the trapezoidal area. According to the packaging bag, the two-dimensional code is hidden in the sealing opening of the packaging bag, so that the phenomenon of illegal brushing is avoided, the sealing opening is convenient to disassemble, and the packaging bag cannot be damaged or the integrity of the two-dimensional codecannot be damaged.

Description

technical field [0001] The invention relates to the technical field of packaging bags, and more specifically relates to a packaging bag with a hidden two-dimensional code. Background technique [0002] In life, people are in contact with all kinds of packaging bags all the time, and there are countless types of packaging bags in terms of shape, size, color, material or use. And setting a lottery QR code on the packaging bag is an attractive way of promotion. [0003] However, some existing products use QR codes to be printed on the visible area on the outer packaging, which is likely to cause fraudulent brushing; others are set in the middle of the bag body and cover the QR codes with the printed layer. Before scanning the codes, you need to First uncover the outer printing layer, destroying the integrity of the bag body, and even causing damage to the packaging bag. [0004] Therefore, it is an urgent problem for those skilled in the art to provide a safe and easy-to-disa...
