One of North America’s largest merchant suppliers and converters of polyester films—stocking >10,000,000 lb of film for 24–48‑hour shipment on most common specs. We slit, coat, treat, sheet, wind, print, and toll convert; we do not produce resin or base PET in‑house.
Our Greer, South Carolina converting and distribution hub sits in the heart of the U.S. polyester ecosystem—adjacent to primary PET/BOPET production in Greer (e.g., Mitsubishi Polyester Film)—for resilient supply and tight spec control through short logistics loops.
Flexible packaging (food, pharma, lidding), electrical insulation, electronics, graphics/print, labels/liners, and industrial laminations.

APET/CPET tray lidding
- Pick: Heat‑sealable PET 12–36 µm, peelable to APET/CPET; seal 250–330°F, COF tuned to 0.3–0.5 for machineability.
PSA label/graphics liner
- Pick: Silicone‑coated PET 23–75 µm, COF 0.2–0.4, controlled release; backside printable acrylic‑treated if needed.
Electrical insulation
- Pick: Industrial/UL PET 50–190 µm, dielectric >3 kV/mil, tight camber; slit widths to ±0.005″.
Sustainable laminations
- Pick: PCR PET (30–90% PCR), treated to 38–44 dyn; metallize if high barrier is needed (+ PE or BOPE for recycle‑ready structures—let’s align on your recycler spec).
