What Are Polyester Films and Their Core Properties?
Polyester films represent a pinnacle of polymer engineering, primarily crafted from polyethylene terephthalate (PET) resin. At Pilcher Hamilton Corporation, the foremost polyester film supplier in the United States, we specialize in producing and converting these films to deliver unparalleled performance across diverse applications. The manufacturing process involves extruding molten PET into a thin sheet, rapidly cooling it to form an amorphous structure, and then biaxially stretching it—first in the machine direction and then transversely—to align the molecular chains. This biaxial orientation is key to unlocking the film’s superior attributes, making it far more robust than non-oriented alternatives.
The core properties of polyester films make them indispensable. Mechanically, they boast tensile strengths of 200-300 MPa, allowing them to withstand significant stress without breaking. Their elongation at break ranges from 80-150%, providing flexibility alongside durability. Thermally, polyester films from Pilcher Hamilton endure temperatures from -70°C to 150°C, with a melting point around 260°C, ensuring stability in heat-intensive processes like sealing or sterilization.
Barrier properties are a standout feature. Plain polyester films offer oxygen transmission rates (OTR) of 80-120 cc/m²/day and moisture vapor transmission rates (MVTR) of 15-25 g/m²/day. However, through our advanced coating and metallization services, we can enhance these to below 1 cc/m²/day and 1 g/m²/day, respectively, providing maximum protection against environmental factors. Optically, our high-clarity polyester films achieve light transmission exceeding 90% with haze under 1%, ideal for applications requiring transparency.
Electrically, polyester films excel with dielectric strengths of 150-250 kV/mm and high volume resistivity (>10^17 ohm-cm), making them perfect for insulation. Chemically inert, they resist acids, bases, and solvents, ensuring long-term reliability. At Pilcher Hamilton, we further optimize these properties with treatments like corona discharge, raising surface energy to 42-58 dyne/cm for better adhesion in printing and lamination.
Polyester film manufacturies, such as those at Pilcher Hamilton, emphasize precision. Our processes include inline quality checks to maintain uniformity, with gauges from 6 to 350 microns available. For sustainability, we incorporate post-consumer recycled (PCR) content up to 100% in select grades, reducing environmental impact while preserving performance.
Variations abound in our lineup. For instance, our acrylic-coated polyester films enhance printability, while silicone-coated release films offer low coefficient of friction (COF) for easy release. Searching for “polyester near me” often leads businesses to our Greer, SC facility, where we provide tailored solutions.
The molecular composition—alternating ethylene glycol and terephthalic acid units—contributes to crystallinity levels of 30-50%, bolstering barrier and thermal traits. In comparison to other plastics, polyester films’ Young’s modulus of 3-5 GPa outperforms polyethylene’s 0.1-0.3 GPa, enabling thinner, lighter designs.
Pilcher Hamilton’s commitment to innovation in polyester film manufacturies includes developing grades with high COF low slip for better stackability in packaging lines. Our technical datasheets provide detailed specs, including density (1.39-1.41 g/cm³) and thermal expansion (15-25 ppm/°C).
For those in South Carolina seeking a polyester film supplier, our location ensures quick access. Polyester film manufacturies like ours integrate sustainable practices, using energy-efficient extrusion to minimize carbon footprints.
In electrical contexts, the low dissipation factor (0.002-0.005) reduces energy loss, a key advantage. Our electrical insulating UL-approved films meet rigorous standards.
Chemically treated options improve wettability, crucial for coatings. Pilcher Hamilton’s expertise positions us as the go-to for “polyester near me” queries.
