Heavy-gauge polyester film (>50 microns) — engineered for electrical insulation, motor applications, and industrial printing. Available in clear, milky white, and hazy variants with exceptional dielectric properties.
When standard thin films aren't enough, thick polyester films deliver the mechanical strength, dielectric performance, and dimensional stability that heavy-duty industrial applications demand.
High dielectric strength makes thick polyester films the go-to choice for motor insulation, capacitor manufacturing, and cable wrapping in electrical applications.
Increased thickness delivers superior stiffness and durability. Withstands heavy handling, vibration, and mechanical stress without deformation.
Withstands high temperatures during processing and continuous use without deforming. Reliable performance in motor and transformer applications.
Clear, milky white, and hazy options for different applications. Milky white films are ideal for electrical insulation, while clear films suit printing and display.
Excellent printability for signage, banners, screen printing, offset printing, and flexo printing. Can be laminated with other materials for enhanced properties.
Depending on thickness and composition, offers barrier protection against moisture, gases, and odours for industrial packaging and protective applications.
Ground and phase insulation for motors, slot insulation in rotating machines, interturn and liner insulation, coil and cable wrapping.
Screen printing, offset printing, flexo printing, injection printing, and blistering. Stiff substrate for high-quality print reproduction.
Capacitor dielectrics, heat transfer substrates, protective covers, and industrial packaging where rigidity and durability are required.
Point-of-sale displays, indoor/outdoor signage, banners, and rigid display panels. Excellent dimensional stability and surface quality.
