Every sealed package tells a story — of quality, preservation, and trust. Behind that story lies a material that quietly ensures it all works perfectly: heat sealable PET. Whether used in snack pouches, medical sachets, or industrial laminates, this specialized polyester film is what allows packaging to stay fresh, secure, and visually flawless.
At Pilcher Hamilton Corporation (PHC), we’ve been engineering excellence in polyester converting since 1904. Headquartered at 850 South Buncombe Road, Greer, South Carolina, PHC is one of the largest merchant suppliers and converters of PET films in the United States.
With over 10,000,000 pounds of film inventory and 24–48-hour nationwide delivery, PHC serves converters and brands who search “polyester near me” — offering unmatched reliability, speed, and technical support.
What Is Heat Sealable PET?
Heat sealable PET (Polyethylene Terephthalate) is a polyester film engineered with a surface layer that activates and bonds under heat and pressure. This capability enables airtight, tamper-resistant seals for flexible packaging across food, healthcare, and consumer product markets.
The film’s core polyester base offers exceptional mechanical strength, optical clarity, and dimensional stability, while the sealant layer provides reliable adhesion and barrier performance.
Key benefits of PHC’s Heat Sealable PET include:
- Strong, consistent seals across a wide temperature range
- Excellent optical clarity for high-visibility packaging
- Superior moisture and oxygen barrier
- High-speed machinability on VFFS and HFFS systems
- Excellent print adhesion and lamination compatibility
- Sustainability options including Post-Consumer Recycled (PCR) content

The Science Behind the Seal
When heat and pressure are applied, the specialized surface layer of heat sealable PET softens and forms a fusion bond with another surface — creating a reliable, leak-free closure. Once cooled, the seal retains its integrity, ensuring long-term protection and shelf stability.
At PHC, we fine-tune this process to meet the requirements of high-speed sealing lines. Our coated PET films deliver clean, consistent seals without distortion, curling, or film breakdown.
Typical seal initiation temperatures (SIT) range from 80°C to 150°C depending on formulation, allowing converters to optimize speed and efficiency. Each roll is tested for:
- Seal strength and peel resistance
- Temperature tolerance and adhesion
- Barrier consistency (MVTR/OTR)
- Optical performance
With PHC’s engineering precision, every seal tells a story of consistency and quality.
