1. A method for manufacturing a gold and silver yarn, comprising
step 1: coating a corona surface of a flexible thin film with a longitudinal discontinuous stripping layer;
step 2: coating the corona surface and the stripping layer with a metal layer; and
step 2: removing the stripping layer and the metal layer on the stripping layer to obtain a packaging material; and
longitudinally cutting the packaging material to obtain the gold and silver yarn,
wherein the stripping layer is a fat-soluble stripping layer.
