Established in 1999, Great River Plastics produces high quality custom-designed plastic packaging such as clamshells and dunnage trays. We contract for large quantity projects (10,000 part minimums for custom clamshells and most other products). Professional packaging design services are included with the project contract.
Pat Obma, Owner
I have been working in the engineering field and plastics industry since 1997. I owned and operated an industrial electrical contracting firm from 1977 until 1999. I am still a licensed Master Electrician. I have worked in and around manufacturing through both of these businesses for 38 years. I worked on the railroads in college and am still a big “RR fan”. My son is an Amtrak locomotive engineer. I have been a licensed amateur radio operator (call sign KC9NBT) off and on since 1964. I also collect antique pendulum clocks and Red Wing advertising bean pots.
Through the years, our experienced team has handled some interesting requests and challenging projects. If you need protective packaging for manufacturing parts or clamshell packaging for finished products, give us a call at 800-914-8994 or 608-723-5110.
