Abstract

A system and method for joining a plurality of paper material together with ultrasonic welding to form a hang tab for displaying products, such as, e.g., in a retail environment, without the use of an adhesive, such as, e.g., glue, and/or printing dye or ink. The paper hang tab may replace plastic hooks or tabs, which may be more environmentally beneficial. Two or more pieces of paper may be inserted into a gap between a sonotrode and an anvil of an ultrasonic joining device. A joining force from an actuator may be applied to secure the pieces of paper, and the sonotrode may oscillate a high-frequency. Adequate compaction of the pieces of paper is produced in addition to a high development of heat from friction generated in the micro-region of the thermoplastic coating. Melting of thermoplastic coating then forms a physical connection between the pieces of paper, effectively fusing them together.
