In packaging, a seal isn’t just a finishing step—it’s the barrier between product integrity and product failure. From food pouches to pharmaceutical packs, every seal must be strong, reliable, and consistent. That’s why converters rely on heat-sealable polyester films, engineered to provide exceptional sealing performance without compromising clarity or toughness.
For more than a century, Pilcher Hamilton Corporation (PHC) has supplied converters across the U.S. with precision-engineered PET films. From our headquarters at 850 South Buncombe Road, Greer, South Carolina, we maintain over 10,000,000 lbs of inventory and deliver nationwide in 24–48 hours. For teams searching “polyester near me,” PHC is the trusted partner for sealing solutions that work.
What Are Heat-Sealable Polyester Films?
Heat-sealable PET films are polyester substrates designed with a specialized sealant layer that activates under heat and pressure. Unlike standard polyester, these films bond securely without needing extra adhesives, making them efficient and versatile for packaging.
Key Benefits:
- Consistent Seal Integrity: Ensures airtight packaging for sensitive products.
- Energy Efficiency: Seals at lower temperatures, saving time and energy.
- Clarity & Aesthetics: Maintains transparency and surface quality.
- Versatility: Compatible with laminations, printing, and coatings.
PHC provides detailed film specifications and technical datasheets for heat-sealable grades.
Applications of Heat-Sealable PET Films
Food Packaging
- Snack pouches, frozen food wraps, bakery bags.
- Seal integrity preserves freshness and reduces food waste.
- Works well with barrier laminates.
Pharmaceuticals
- Blister packs and medical device pouches.
- Maintains sterility and prevents contamination.
Industrial Packaging
- Protective wraps for chemicals, adhesives, and powders.
- Combined with PVDC coatings for enhanced oxygen and moisture resistance.
Specialty Laminates
- Compatible with acrylic-coated and metallized films for customized packaging structures.

Heat-Sealable Films vs. Standard Polyester
Why choose heat-sealable PET over traditional PET?
- No additional sealant layers required → reduces complexity and cost.
- Faster line speeds → packaging operations run more efficiently.
- Better adhesion compared to untreated PET → ensures strong seals on demanding lines.
When compared to general-purpose industrial films, heat-sealable PET is optimized for packaging where shelf life and seal reliability are non-negotiable.
