Design & Development

We work as a team with our customers to design a package perfectly suited for its contents and logistical requirements. We adhere to a strict package safety criteria and team with Cornerstone Engineering Group in Maryville, TN when more complex engineering is required. We constantly work with our material suppliers to improve, innovate, and test every component of our packages.

Package Testing

SPS has the ability to do in house testing for strength, lifting, and U.S. D.O.T. requirements for IP-1 and IP-2 packaging. We also require our component material suppliers to submit certified test results with every lot manufactured.


SPS provides to our customers a no cost working prototype of each new style package they request. This service is to ensure the usability and safety of the package.
