Copper4 PTFE Tape is a high-performance, non-metallic heat sealing tape engineered for demanding industrial and packaging applications. Unlike traditional dip-coated tapes, Copper4 features a PTFE film laminated to a fiberglass fabric substrate, creating a smooth, pinhole-free working surface that delivers superior durability and longer service life.

Pinhole-Free Surface for Consistent Sealing

The laminated PTFE construction provides a perfectly smooth sealing surface that allows heat, pressure, and release agents to transfer evenly. This ensures consistent, precise heat seals, making Copper4 ideal for applications where reliability and seal quality are critical.

High-Temperature Silicone Adhesive

Copper4 PTFE tape is coated with a high-temperature silicone adhesive that bonds securely to sealing jaws and equipment surfaces, even under extreme heat. A yellow dimpled release liner allows for easy installation and clean application.

Ideal for Packaging & Medical Sealing

Copper4 is widely used in food packaging and medical packaging for sealing heat-sealable films and materials. The pinhole-free PTFE surface helps prevent leaks, protect product integrity, and maintain sterile packaging conditions.

Industrial Heat Sealing Applications

This tape is also used across industrial manufacturing for:

• Sealing industrial bags, pouches, and laminated materials

• Fabrication of flexible ducting

• Heat sealing of specialty films and composites

Electronics, Automotive & Aerospace Uses

Copper4 PTFE tape provides heat resistance, insulation, and moisture protection for heat-sensitive components, electrical connectors, and wiring harnesses in high-performance environments.

Copper4 PTFE Tape delivers reliable release, high-temperature resistance, and long service life for critical heat sealing applications across multiple industries.
