Problems solved by technology

In order to make the two-dimensional code clear and easy to distinguish, it is generally printed on the bottom layer of the white display. Due to the decorative pattern and in order to highlight the two-dimensional code, the domestic packaging bag will be printed again in white after printing the two-dimensional code, which not only increases the process flow , and during the handling process of such packaging bags, due to the friction between the packaging bags, the two-dimensional code printed on the outer surface of the packaging bag will appear broken, blurred, and fall off, making it impossible for the terminal scanner to scan the two-dimensional code. After activating the recognition and reading, the relevant information of the product cannot be queried, and the meaning of setting the QR code is lost

Abstract

The invention discloses a packing bag two-dimensional code printing method. The packing bag two-dimensional code printing method comprises the following steps in sequence: (1) a decoration pattern is printed on the frontal surface of a packing material for manufacturing a bag body; and a blank position for printing a two-dimensional code is reserved in the decoration pattern; (2) the two-dimensional code is printed in the blank position; and meanwhile, a number same with the content of the two-dimensional code and a hidden fluorescent digital code are printed on the back surface of the packing material; (3) the frontal surface of the packing material is coated with a transparent white film; and the back surface of the packing material is coated with a hot-sealed inner film; (4) the packing material is fed in a curing chamber for heating and curing; and (5) the hot-sealed inner film is inwards formed to a packing bag or slit to a winding film.

Description

technical field [0001] The invention relates to a printing method of a packaging bag, in particular to a printing method of a two-dimensional code of a packaging bag. Background technique [0002] The two-dimensional code printed on the product packaging bag contains important product-related information such as the manufacturer of the product and the expiration date, which can be identified and read by the terminal scanner, and consumers can quickly and conveniently inquire through telephone inquiries, SMS inquiries, and online inquiries. Produce product information in order to trace and track products. At present, the Ministry of Commerce, the General Administration of Quality Supervision, Inspection and Quarantine and the State Administration for Industry and Commerce have formulated requirements that the packaging bags of nine categories of products such as food, medicine, agricultural materials, and chemicals must be marked with QR codes. Coercive measures for regulator...
