Presco’s extrusion history started in 1975 when Earl McMackin, the President and owner of Presco, and his son Waymon starting exploring ways to make the growing marking products line more efficient. Up until that point, Presco purchased flexible vinyl film from outside vendors to make stake flags and roll flagging. Earl and Waymon decided to extrude vinyl film in house for a more vertically integrated manufacturing process.

In 1976, the first sellable pounds of flexible vinyl film were extruded for the stake flag and roll flagging product lines. Manufacturing the vinyl at Presco allowed for customization of the formulations for better performance. It also allowed for custom emboss patterns such as the famous Texas embossed roll flagging.

Fast forward to 1980 and Waymon McMackin, Earl’s son, is now the President of Presco. Waymon knew the vinyl film extruded for marking products could be sold in bulk roll form to other manufacturers utilizing vinyl film in their products. In 1981, Presco landed their first Engineered Film customer. In 1989, Presco relocated from Dallas to Sherman, TX. This move allowed Presco to tap into a very experienced industrial workforce Sherman had to offer. The new plant in Sherman allowed for the second extruder to be added later that year and a third in 2003.

Thank you to our customers, vendors and partners who have made the last 40 years extruding vinyl film possible. We are looking forward to continued growth and new capabilities. Get ready for the next 40 years!



Since 1975, Presco has extruded vinyl film at our facility in Sherman, Texas.

Being an American manufacturer of vinyl film in an industry battered by offshore competition is not for the faint of heart. Presco’s Engineered Film has remained competitive in our markets by partnering with customers who not only value the domestic vendor relationship but rely on the benefits it brings their supply chain and product quality standards.

We encourage our customers to explore the total cost of offshore vendors rather than focusing on just the price per unit. At Presco, we can offer shorter lead times, stellar customer service, flexible payment terms, inventory capabilities and most importantly a PARTNERSHIP WITH YOU to custom develop solutions for your products. A partnership that starts with manufacturing Presco’s Engineered Film to the highest quality standards.

Please take a moment to read a testimonial from one of our valued customers and learn how purchasing domestically provides BIG savings over the imports.




The Presco attitude starts at the top building the famous Presconian pride!
