Quality Control


Douglas Stephen Plastics, Inc. has an extensive Quality Control process that ensures our customers receive consistent high quality products that perform as expected, case after case.  This starts with our Extrusion Division, where we make our own Polypropylene (PP), High Impact Styrene (HIPS) and Polyethylene Terephthalate (PET).  High quality raw materials provide the fundamentals for quality thermo-forming.  This enables us to control the quality of the regrinds we blend back into our material.  As a result, DSP can certify minimum levels of regrinds at 50% for all our products (except where virgin material is specified). 

All materials processed by DSP have USDA/FDA certification and are safe for direct food contact.

Our production facility has a professional QC department, who constantly monitor all production.  Everything packed in our boxes meets the internal specifications for product performance, clarity and aesthetics.  This quality control is present during the 24 hours a day we manufacture.

DSP stands behind the performance and quality of all the products we manufacture, giving you and your customers peace of mind.
