When it comes to packaging performance, the seal is everything. It’s the line between freshness and spoilage, stability and waste, trust and failure. That’s why PET film sealing has become a defining technology across industries that demand consistency, safety, and sustainability.
For over 120 years, Pilcher Hamilton Corporation (PHC) has helped shape the future of polyester converting and film innovation. Founded in 1904 and headquartered at 850 South Buncombe Road, Greer, South Carolina, PHC has grown into one of America’s most trusted and largest suppliers of polyester films (PET).
Our reputation for reliability, fast delivery, and technical precision has made PHC the first stop for converters and manufacturers searching “polyester near me.” From snacks to pharmaceuticals, from industrial laminates to flexible pouches — PHC’s PET sealing films ensure performance in every layer.
The Science Behind PET Film Sealing
PET (Polyethylene Terephthalate) is one of the most advanced and versatile thermoplastic polymers in packaging. Its combination of thermal stability, mechanical strength, and chemical resistance makes it ideal for applications that require dependable sealing performance.
At PHC, our heat sealable PET films are produced with specialized coatings or coextruded sealant layers designed to activate at controlled temperatures. Once heat and pressure are applied, the polymer surface softens and bonds, creating an airtight, tamper-resistant seal that protects against leaks, moisture, and oxygen.
Technical advantages include:
- Precise seal initiation temperatures (SIT) for efficient machine performance
- Consistent seal integrity and peel strength
- High clarity and print adhesion for premium packaging appeal
- Resistance to delamination, cracking, or deformation during sealing
- Compatibility with VFFS and HFFS systems for high-speed packaging

Why PET Films Are the Standard for Sealing Applications
PET films outperform many traditional packaging materials due to their unique balance of clarity, strength, and versatility. Unlike polyolefin or PVC films, PET maintains its structural integrity at both high and low temperatures — a crucial feature for applications like frozen foods, medical pouches, and retort packaging.
1. Superior Seal Strength
PHC’s sealing films form airtight and durable seals that prevent leaks and protect contents against contamination.
2. Enhanced Barrier Protection
When paired with coatings such as PVDC or acrylic, PET provides excellent resistance to moisture, gas, and aroma transmission, extending product shelf life.
3. Smooth Machinability
The dimensional stability of PET ensures seamless operation on high-speed packaging lines, minimizing waste and downtime.
4. Clarity and Aesthetics
Transparent PET films showcase products beautifully while providing reliable structural support.
5. Recyclability and PCR Integration
PET is a recyclable thermoplastic, and PHC offers Post-Consumer Recycled (PCR) film options for brands committed to sustainability.
Whether sealing a snack pouch or a sterile medical package, PET’s adaptability makes it the universal choice for converters seeking reliability and efficiency.
Applications of PET Film Sealing
PHC’s sealable polyester films are trusted across multiple industries that require precision and protection.
Food Packaging
- Snack pouches, bakery films, frozen food wraps, and resealable bags
- Lidding films for ready-to-eat meals, yogurt, and refrigerated goods
Pharmaceuticals & Healthcare
- Medical sachets, diagnostic pouches, and sterile barriers
- Blister laminates and transdermal adhesive packaging
Industrial & Technical Uses
- Sealable laminates for electronic components, insulation, and adhesives
- Moisture and chemical-resistant liners for specialty applications
Consumer Goods & Personal Care
- Sachets and flow-wraps for shampoos, gels, and creams
- Tamper-evident packaging for safety and brand protection
By combining seal integrity, visual quality, and performance durability, PHC’s PET films deliver the exacting results industries rely on.
The PHC Difference: Expertise in Every Roll
At Pilcher Hamilton Corporation, excellence in converting is not an option — it’s a tradition. Our expertise in film coating, slitting, and surface modification ensures that every roll of PET film meets precise specifications for adhesion, tension, and sealing response.
Our converting services include:
- Slitting for precise roll widths
- Sheeting for customized dimensions
- Winding & Rewinding for uniform roll tension
- Toll Converting for customer-supplied materials
- Coating and Corona Treating for improved adhesion and surface energy
Every batch undergoes seal performance, coating uniformity, and optical testing to guarantee absolute consistency. With over 10 million pounds of polyester film inventory, PHC ensures rapid turnaround — typically within 24–48 hours.
Sustainability in PET Film Sealing
Sustainability is now a performance metric — and PHC is leading the charge. Our heat sealable PET films can be produced using Post-Consumer Recycled (PCR) resin while maintaining identical sealing strength and clarity.
Through PHC’s Sustainability First Program, we help packaging engineers design eco-optimized, recyclable structures that align with corporate environmental goals.
From reducing material thickness to developing mono-material laminates, PHC supports the circular economy — one high-performing seal at a time.
