Our History
Engineered to service
With an interest in the new and developing field of plastics and some basic mechanical skills, Ralph A. Unthank, started a small company in 1954. A packaging machine was designed and built with the help of his son, Randy, and the seeds were sown.  
Several decades and expansions later we are still family owned, servicing businesses around the globe. 
Our mission is to enable our customers to operate more effectively. Our clients put their reputations in our hands and that is a responsibility we take incredibly seriously.
We make quality our highest priority. As industry leaders, it is built into everything we do, for every client. Our team is committed to delivering impeccable standards and results.
