At Diamond Flexible Packaging, quality control is the most important aspect of our business. We believe that is why we have such a remarkably high customer retention rate. Providing a first-class product isn’t something we just say, it’s something that we do day after day, run after run. We produce our pouches, roll-stock, and custom bags to the highest quality standards available and we stand behind our work.

Diamond Flexible Packaging has an extensive quality control system that is easily tailored to fit any customer’s needs. We have all the necessary testing equipment in-house allowing us to easily provide full traceability – a product can be sourced from film origin to machine operator.
