Global Polyester Film Electrical Tape Market Strategic Research Report

Scope of the Report

The global Polyester Film Electrical Tape market size is predicted to grow from US$ 1,006 million in 2025 to US$ 1,530 million in 2032; it is expected to grow at a CAGR of 6.3% from 2026 to 2032.

In 2025, global production of polyester film electrical tape reached 1.3 billion square meters, with an estimated average selling price of US$0.74 per square meter. Polyester film electrical tape is an electrical insulating tape made by coating PET polyester film with acrylic adhesive, rubber-based adhesive, silicone, or thermosetting pressure-sensitive adhesive. It is mainly used to provide high dielectric strength, mechanical strength, dimensional stability, solvent resistance, and heat resistance at relatively thin thicknesses. It is favored in industrial manufacturing and electronic and electrical insulation applications, used for insulation of motor/generator end windings, and also in electronics, automotive, aerospace, composite material protection, and PCB manufacturing. The upstream of the industry chain mainly includes PET/BOPET film, acrylic adhesive, rubber resin adhesive, silicone, flame retardants, tackifying resins, release materials, paper tubes, packaging materials, coating equipment, slitting and rewinding equipment, and cleanroom testing equipment. The midstream involves substrate surface treatment, adhesive coating, drying, curing, rewinding, slitting, die-cutting, UL/CSA and other electrical certifications, and brand sales. The downstream mainly targets the transformer, motor, relay, inductor coil, capacitor, home appliance, consumer electronics, power adapter, automotive wiring harness, new energy vehicle power battery, energy storage system, industrial control, and repair and maintenance markets. Gross profit margin is approximately 20%–40%.

Regionally, demand in the Asia-Pacific region—specifically China, Japan, Taiwan, and Southeast Asia—is driven by the electronics manufacturing, transformer, electric motor, home appliance, new energy vehicle (NEV), and battery supply chains. The North American market is primarily driven by demand in the automotive, electrical equipment, and industrial maintenance sectors, while the European market places greater emphasis on flame retardancy, halogen-free properties, certifications, and high-reliability applications. Key industry trends include: first, the growth of NEVs, energy storage systems, battery packs, and high-voltage wiring harnesses is driving the upgrade of electrical tapes toward flame-retardant, halogen-free, electrolyte-resistant, and heat-resistant specifications, as well as die-cut insulation applications; second, steady demand from the transformer, electric motor, and industrial automation sectors continues to support the market for interlayer insulation and coil-securing tapes; and third, the miniaturization of electronic components and the widespread adoption of automated winding equipment are driving the development of tapes that are thinner, more stable, and better suited for automated application and wrapping processes.
