patent name packaging bag with laser anti-counterfeiting function patent applicant Qi Guolin main applicant address 310017 inventor Qi Guolin application (patent) No. of group 9, Pengbu village, Pengbu Town, Jianggan District, Hangzhou City, Zhejiang Province 1. Application date: June 16, 2004 date of issue approval Announcement No. approval announcement date: September 28, 2005 CD No. d0539 main classification No. b65d30/00 classification No. b65d30/00; B65D65/40； The utility model relates to a packaging bag with laser anti-counterfeiting function. On one side of the flexible base material PET polyester plastic film, from top to bottom, there are a bonding resin layer, a laser information layer and a small alloy layer. The graphic shape in the laser information layer is precisely nested with the small area of the alloy layer that needs anti-counterfeiting effect. The beneficial effect of the utility model is that the attachment of the tensile testing machine which is not easy to be made is mainly used to fix the counterfeiter of the sample, which can achieve the anti-counterfeiting effect and the aesthetic purpose at the same time. And because the anti-counterfeiting pattern is generally a small scattered pattern, which is firmly combined with the substrate and is not easy to fall off, it is especially suitable for shrinking the packaging film. Claim 1. A packaging bag with laser anti-counterfeiting function, which is characterized in that the surface of the packaging bag (5) on one side of the flexible base material PET polyester plastic film (1) is successively composed of an adhesive resin layer (4), a laser information layer (2) and a small alloy layer (3) from top to bottom, The image and text shape in the laser information layer (2) and the small area of the alloy layer (3) that needs anti-counterfeiting effect are precise. At the same time, the focus shift signal is discussed through the detection angle, and it is sent to the computer to stop data processing.
