Advanced Functional Films
Ultra-Thin Transparent PET Films
Ultra-thin transparent PET films designed for applications requiring superior optical clarity, mechanical strength, and surface stability.
The range includes standard ultra-thin transparent PET films and pre-coated PET films with enhanced adhesion.
These films offer excellent thickness uniformity, high tensile strength, smooth surfaces, and reliable electrical insulation, making them suitable for electronic tapes, photosensitive materials, electrical insulation films, industrial uses, packaging, decorative products, lamination layers, protective films, and optical components.
Polyimide (PI) Film Series
Polyimide (PI) is a high-performance “golden film” known for superior heat resistance, mechanical strength, electrical insulation, chemical stability, and flexibility.
Thanks to its high-purity formulation, low shrinkage rate, and excellent processability, Terapec PI films are widely used in flexible electronics, 5G communication systems, next-generation display technologies, thermal management solutions, aerospace, and high-temperature insulation.
The portfolio includes PI films for:
- Electrical Insulation (e.g., general insulation, corona-resistant films, composite insulation films, thermoplastic PI composites)
- Electronics Manufacturing (FPC, FCCL, 2L-FCCL, electronic tags, black PI for optical protection and circuit isolation, low-Dk PI for high-speed 5G)
- Thermal Control (graphitizable PI and thermally conductive PI for smartphones, tablets, and wearables)
- Flexible Optoelectronics (colorless, transparent, and white PI for flexible displays, lighting, and film solar panels)
Advanced Functional Films for Electronics & Energy Systems
A comprehensive portfolio of adhesive tape base films and specialty functional films engineered for insulation, adhesion, optical performance, and metallic appearance.
These films combine uniform thickness, high tensile strength, excellent electrical insulation, and stable optical properties, ensuring flawless convertibility in coating, lamination, and slitting.
The product families include:
- Functional Base Films – Transparent adhesive tape and aluminum-plastic laminate base films for electronic adhesive tapes, photosensitive films, packaging materials, and new energy insulation layers.
- Optical & Light-Control Films – White adhesive tape films offering brilliant whiteness, light-blocking capability, and high gloss for signage, printing, IC cards, and reflective packaging materials.
- Metallic Appearance Films – Golden adhesive tape films with long-lasting metallic gloss and reliable electrical insulation for electronics, electrical appliances, adhesive tapes, and industrial films.
- Energy Storage Application Films – Green and blue adhesive tape base films designed for terminal insulation, end wrapping of prismatic and cylindrical battery cells, and surface insulation/protection of aluminum battery casings.

Do the films support high-temperature and high-voltage environments?
Yes. Polyimide films are designed for high-temperature and high-voltage insulation, including corona-resistant grades for traction motors, wind turbines, and EV systems. Advanced PET and functional base films provide stable insulation and dimensional control under demanding industrial conditions.
What film formats and features are available?
The portfolio includes films with various thicknesses, mechanical strengths, optical properties, heat shrinkage levels, and surface coatings, as detailed in the technical specifications for each product type (e.g., ultra-thin PET, white/black/colored adhesive tape films, metallic gold films, PI series).
How can I choose the right film for my application?
The choice depends on factors such as selection, temperature range, voltage level, mechanical stress, optical requirements (transparency, reflectivity, color), and processing method (coating, lamination, slitting). Therpec’s material experts can help you select the most suitable PET, PI, or functional base film for your device or system’s requirements.
Are there any special storage or transportation requirements for these films?
In general, PET, PI, and functional films should be stored in clean, dry areas away from direct sunlight, dust, and high humidity.
Keeping the roll packaging sealed helps maintain surface quality and prevent contamination before processing.
