Flexible packaging bag with identification codes

Abstract

The invention discloses a flexible packaging bag with identification codes. The flexible packaging bag comprises a packaging bag body formed by bonding a front bag body and a rear bag body, wherein atleast two mutually isolated cavities are formed in the packaging bag body; the first cavity is used for containing a goods body; the second cavity is used for containing the surface of a carrier capable of carrying the first identification code; and the first cavity is isolated from the second cavity by the bonding part. According to the flexible packaging bag, the first identification code is arranged in the closed second cavity and cannot be obtained until the flexible packaging bag is destroyed; the invisibility and safety of the first identification code are ensured; and by arranging thefirst identification code in the second cavity isolated from the goods body, the first identification code is isolated from the goods body, so that the safety of the goods body is ensured.

Description

technical field [0001] The invention relates to a flexible packaging bag with an identification code, which belongs to the field of anti-counterfeiting packaging. Background technique [0002] As society's demand for flexible packaging bags increases year by year, flexible packaging bags are gradually covering the market based on their inherent characteristics of bright colors, novel patterns, and ease of use. However, since most small and medium-sized packaging companies do not have the ability to produce anti-counterfeit products, the lack of anti-counterfeit technology for flexible packaging bags gives counterfeiters an opportunity. In recent years, with the popularization of the application of QR codes, various food manufacturers have proposed a marketing plan to set QR codes on food packaging. Consumers can participate in the manufacturer's point lottery and other activities as long as they scan the QR code with their mobile phones. [0003] In order to achieve anti-co...

Problems solved by technology

This marketing method can be used for foods that are packaged in small bags, but for foods that are directly packaged in bags, especially foods that are directly imported, because the logo on the inner surface of the bag Codes will inevitably come into contact with food, posing safety hazards

Moreover, the identification code is directly set in the inner cavity of the packaging bag, because the packaging bag will be deformed after putting in the food, which is not conducive to the reading of the identification code

For example, when the inner code is set near the edge of the opening, because the surface of the packaging bag is uneven after packaging the food, it is difficult to recognize or cannot be recognized when reading the identification code data on the production line; especially when vacuum packaging rice, beans, etc. Granular products are basically unrecognizable; if the inner code is set at a non-edge position and in an easily identifiable area (such as in the middle of the packaging bag), it is not easy for consumers to obtain the QR code set inside the packaging bag , you need to use tools such as scissors to unpack the package to get the inner code pattern
