Every time you tear open a bag of chips or unseal a snack pouch, you’re experiencing the precision of materials science at work. Behind every satisfying crunch is a hidden innovation — the strength and sealability of heat sealable polyester films. These high-performance materials are what make today’s snack packaging not only reliable and attractive but also sustainable and efficient.
For more than a century, Pilcher Hamilton Corporation (PHC) has been synonymous with excellence in polyester film converting. Founded in 1904 and headquartered at 850 South Buncombe Road, Greer, South Carolina, PHC stands as one of the largest U.S. suppliers and converters of PET films. Whether you’re developing new flexible snack packaging or refining existing laminations, PHC is the partner of choice for anyone searching “polyester near me.”
The Science Behind Heat Sealable Polyester Films
Heat sealable polyester films are engineered for one key purpose — to form airtight, tamper-resistant seals under controlled temperature and pressure. This capability allows food manufacturers to protect freshness, preserve flavor, and extend shelf life without relying on heavy or multilayer structures.
At PHC, our heat sealable PET films are precision-designed to maintain strong seals while offering excellent optical clarity, high tensile strength, and superior barrier performance. These films are suitable for both vertical and horizontal form-fill-seal (VFFS and HFFS) packaging systems — making them ideal for snack pouches, energy bar wrappers, and resealable bags.
Our products also provide thermal resistance and shrink stability, ensuring they hold their form during sealing and storage, even in high-speed packaging environments.

Why Snack Packaging Depends on Reliable Heat Sealing
Snack packaging must balance visual appeal, mechanical protection, and freshness retention — all within lightweight, flexible materials. Heat sealable polyester films deliver on every one of these requirements.
- Airtight Protection – Heat sealing creates hermetic closures that prevent air, moisture, and contaminants from entering. This ensures crispy, flavorful snacks every time.
- Extended Shelf Life – With barrier coatings such as PVDC or metallization, PHC’s polyester films enhance moisture and oxygen resistance, allowing snacks to stay fresh longer.
- High-Speed Performance – Our films are designed for compatibility with high-output machinery, delivering clean seals without distortion or residue.
- Durability and Print Clarity – PET films provide excellent surface uniformity for vibrant printing, graphics, and branding — key to standing out on store shelves.
By combining heat sealability with robust barrier properties, PHC enables packaging manufacturers to create snack pouches that are efficient, sustainable, and visually appealing.
From Film to Function: How PHC Converts Innovation into Packaging Performance
Behind every film we produce is a system built on precision converting and deep technical expertise. Pilcher Hamilton’s converting operations include:
- Slitting for perfect edge control and roll uniformity
- Sheeting for custom cut sizes
- Winding and Toll Converting for customer-supplied materials
- Coating and Corona Treating for optimal surface energy and adhesion
Every product passes through strict quality control, including adhesion, seal integrity, and surface testing. This ensures that PHC’s heat sealable polyester films perform consistently across packaging lines and remain compliant with industry standards.
Applications of Heat Sealable Polyester Films in Snack Packaging
From chips to granola bars and trail mixes, heat sealable PET films play an essential role in defining how consumers experience their favorite snacks. Key applications include:
- Single-serve pouches for chips, nuts, and cookies
- Laminated wraps for chocolate bars and confectionery
- Resealable stand-up pouches for cereals or protein bites
- High-barrier laminates for sensitive or oily snack products
When paired with metallized layers or PVDC coatings, these films deliver superior moisture and oxygen protection — critical in preventing flavor degradation and maintaining crispness.
For high-speed snack lines, PHC’s films can be tailored for specific seal initiation temperatures, thicknesses, and friction coefficients, ensuring they integrate flawlessly with existing machinery.
