PET Film Supply Company is a PET functional film supplier for electronics, insulation and outdoor applications. Our range covers conductive, ITO-coated, anti-static, flame-retardant, UV-resistant, heat-stable, low-shrinkage, insulation, anti-fog, matte and surface-treated PET films. For the difference between melting onset, DSC peak temperature, and practical service limits, refer to polyester film melting temperature technical data Each grade is matched to its working condition, test method and downstream process rather than thickness alone.

Functional PET film covers polyester materials designed for different electrical, optical, thermal and surface needs. For china transparent conductive film projects, conductive grades are one branch of a wider portfolio. Other applications need ESD control, dielectric strength, UV stability, low MD / TD shrinkage or stronger coating adhesion. Selection should begin with the operating condition to control.
When comparing pet ito film suppliers, conductivity is only the first check. The grade also depends on clarity, haze, thickness and whether the film will act as an electrode, shielding layer or heating layer. Anti-static film is not a substitute for electrode performance.
For polyester film flame retardant requirements, confirm flame rating separately from dielectric performance. For pet film uv resistance projects, define light exposure separately from thermal processing. UV stability addresses weathering, while heat stability addresses MD / TD shrinkage, flatness and registration. For low-shrinkage grades, record the agreed test condition, such as 150 C, 30 min.
Where sliding resistance affects converting, review the COF testing method for PET film together with the selected coating and tested side.
Thickness is only one part of the specification. A display structure may first require sheet resistance and low haze. Clean electronic processing may depend on surface resistance and reduced dust attraction. Precision coating, lamination and die cutting require attention to MD / TD shrinkage, roll flatness and slit tolerance. Starting with the likely failure point helps avoid anti-static film for an electrode or heat-resistant film where UV exposure is the real concern. For vacuum-metallising projects, review metallised polyester film properties and test data before fixing the PET grade, treated side, thermal-shrinkage limit, or batch acceptance criteria. When the base gauge has not yet been fixed, the PET film thickness range guide explains how nominal thickness, stiffness, measurement method, and production-line trials should be evaluated before functional requirements are added.

As a PET functional film supplier, PET Film Supply Company can match grade, thickness, width, slit size, sheet size and surface treatment to each process. For repeat runs, confirm test method, temperature, exposure time, resistance target, transmittance or haze, treated-side direction, cleanliness, flatness and slit tolerance. Trial rolls are recommended for combined requirements or a new line.
Confirm which side will receive ink, coating, adhesive or lamination, then verify whether the film should be untreated, corona treated, primer treated or chemically treated. Untreated PET is often about 42-46 dyne/cm, while treated surfaces may reach about 54 dyne/cm or above, subject to validation. Corona treatment can improve wettability, but its effect may decline during storage. Before bulk processing, check treated side, dyne level, winding direction and processing window. This helps reduce poor wetting, weak ink anchorage, coating variation and delamination.
Confirm the application, required function, thickness, width, optical target, electrical target, heat condition, surface treatment and format.
No. Conductive PET film serves electrode or shielding functions, while anti-static grades control ESD and dust attraction.
Yes. Confirm treated side and dyne level because treatment performance can change during storage.
Yes. Some projects combine low haze, UV resistance, low shrinkage, insulation or surface treatment. Validate the structure with samples before repeat production.
