Ultrasonic welding can be used in packaging applications where thermoplastic components need to be joined quickly and consistently. Depending on the product design, ultrasonic technology can support sealing, joining, cutting, staking and other assembly operations.
The ultrasonic horn is designed around the packaging component and must transfer vibration evenly across the required working area. Frequency, amplitude, pressure, material and joint design all influence the result.
This article explains how ultrasonic welding can be applied to plastic packaging and containers and what manufacturers should consider when designing an ultrasonic packaging process.
