ISTA Certified & ISO 9001 Registered

As an AS9100 & ISO 9001 registered company, SUMTER PACKAGING CORPORATION has taken the steps to ensure that we have the documentation and controls in place needed to provide the consistent quality corrugated Containers that our customers, and their customers, demand.

As part of Sumter Packaging's commitment to quality, we maintain a fully certified ISTA lab for both 1A and 1B testing. Our testing lab is continuously kept at a controlled environment with a 50% humidity level and 73 degree temperature to ensure consistent, accurate results. Services performed in our testing lab include: Burst Strength Testing (Mullen Test), Basis Weight Testing, and Edge Crush Testing (ECT). We also have, available on-site, an Incline Impact Tester, Rotary Motion Vibration Table, and a Drop Leaf Tester.

Our test lab professionals have also completed UN / Hazardous Materials ("Hazmat") training and would be happy to work with you to coordinate UN / Hazmat testing for your packaging through an independent certified hazmat testing laboratory.

Our quality assurance technicians keep a constant watch over every detail in the process, from the front door to the back. Every machine operator knows, follows and documents detailed quality instructions.


Our certification as a G7 Master Printer means that we use sophisticated prepress technologies, press controls, proofing and on-press measurements in order to ensure a visual match from proof to print. This is yet another step that we take to ensure our customers' peace-of-mind.


Sumter Packaging cares about the environment! We make a conscientious effort to help reduce paper waste, by recycling and reusing, on average, 78% of our recycled material!

The corrugated industry is focused on continuously improving all the ways our processes and products interact with the environment, from forest management to recovery and recycling at the end of each corrugated package's useful life.
93% of corrugated boxes are made with material supplied by the Sustainable Forestry Initiative (SFI) program participants. Corrugated is the most recycled packaging material today with 78.3% of all containers produced being recovered for recycling (25.2 million tons). The average corrugated box consists of 43% recycled fiber.
