Key Takeaways
- Heat-sealable PET enables direct sealing to common tray and pouch substrates.
- Seal performance depends on SIT (Seal Initiation Temp), hot tack, and peel profile.
- Films available with anti-fog, antiblock, and slip additives for production efficiency.
- Typical gauges: 36–92 ga for packaging applications.
Seal Windows & Peel Strength
- SIT ranges: From ~220°F (104°C) up to 300°F (149°C), depending on coating.
- Peel strength: Tuned for lock-seal (non-peelable) or peelable applications.
- Hot tack: Ensures seals hold during fast line speeds and while still hot.

Sealing to APET, CPET, PP & PS
- PET films can be engineered to seal directly to multiple plastics.
- Common in ready-meal trays, yogurt lids, and snack packs.
- Anti-fog coatings maintain clarity in refrigerated display.
Anti-Fog & Antiblock Options
- Anti-fog: Prevents condensation, ensuring clear product visibility.
- Antiblock/slip agents: Improve machinability and reduce film sticking.
- Custom coatings: Explore Coating Services.
Line Trials & Converting
- Conduct sealing trials to determine SIT and dwell for your equipment.
- Confirm COF requirements for form-fill-seal lines.
- Consider lamination with other substrates for barrier enhancements.
