PETG for Thermoforming
Stocked nationwide. Same-day shipping on stock. Custom slitting, sheeting, and cut-to-size.
PETG for thermoforming is the go-to clear sheet for packaging and formed displays because it draws deep without blushing or cracking. K&R stocks optically clear, food-safe PETG in the gauges thermoformers actually run, draws clean on standard vacuum and pressure forming equipment, and ships it the same day on stock items from five distribution warehouses.

Frequently asked questions
- Why is PETG preferred over acrylic or PVC for thermoforming?
- PETG forms at lower temperatures and has a wide forming window, so it draws into deep, detailed shapes without cracking, crazing, or blushing the way acrylic can. It is tougher and more impact-resistant than rigid PVC and contains no chlorine, which matters for clean disposal and food contact. That combination is why it dominates clamshells, blisters, and formed displays.
- Is your PETG food-safe for packaging?
- Yes — we stock FDA-compliant PETG grades suitable for direct food contact, which is why it is widely used for clamshells, trays, and produce packaging. Tell us the application and whether you need a specific food-contact certification and we'll qualify the right grade and supply documentation.
- Do I need to dry PETG before forming?
- PETG is mildly hygroscopic, so for best optical clarity and surface quality we recommend pre-drying sheet that has been exposed to humidity before vacuum or pressure forming. Forming temperatures typically run in the 250–320 F range; the wide window makes it forgiving on standard thermoforming lines. We can advise on handling for your specific gauge.
- What gauge PETG should I use for clamshells versus rigid trays?
- Thin-gauge clamshells and blisters usually run .015 to .030, where the sheet draws fast and trims clean. Rigid formed trays, displays, and guards step up to .040 to .060 for stiffness and load support. We slit, sheet, and cut-to-size in house so you can order the exact gauge and dimensions your tooling calls for.
