Packaging tin capable of shielding two-dimensional code and packaging method

The invention provides a packaging tin capable of shielding a two-dimensional code. The packaging tin comprises a tin body, a shielding object and a two-dimensional code icon. The shielding object shields the two-dimensional code icon on the packaging tin. Due to the fact that an opaque retractable belt or a shielding film is arranged or a tin lid is utilized for shielding the two-dimensional code icon, the code can be scanned only when a consumer purchases the packaging tin and opens the packaging tin in a destructive mode, and the purposes of counterfeiting prevention and interconnection are achieved.
