Clamshell blister packaging has become popular for high visibility of the product, but making the clamshell tamper-resistant is a must. Ultrasonic welding requires no adhesives, heatshrink bands or staples and the final package will have a nice appearance and high strength.
Craig Machinery & Design, Inc. pioneered continuous welding for produce and baking industry packaging machines. This application includes high speed lettuce tub lid welders with speeds of up to 100 fpm.
We can also build machines for plunge welding clamshell packages for a variety of sizes and cycle times. Craig Machinery can build machinery for almost any need, from “simple load under the horn” table systems with two palm buttons to multi-welder rotary indexing machines with an auto eject system and an operator interface touch screen.
