Rigid PETG Thermoformed Packaging
At FormTight, we produce custom PETG packaging for manufacturers who need a high-performing plastic that holds its shape, displays product well, and moves efficiently through production. From retail-ready packaging to medical device packaging, our PETG thermoforming capabilities are built to handle your required production volumes.
What's the difference between PET & PETG?
The main difference between PET and PETG is the addition of a glycol modifier (the “G” in PETG), which removes the hazing effect during the heating of PET. In addition, PETG is more pliable and easier to form than PET, making it an ideal choice for complex thermoformed packaging applications.
Why Is PETG a Preferred Material for Custom Thermoformed Packaging?
- Optical Clarity without PVC risks: Same Shelf impact as PVC, without environmental or health concerns during processing.
- Better Detail, less stress: Thermoforms at lower temps than standard PET for sharper features and less material stress.
- Built for compliance: Impact-resistant, recyclable, and FDA- compliant for direct food and medical device contact.
- Run-to-run consistency: Holds appearance and structural integrity across high-volume production.
PETG Packaging Applications
Rigid PETG thermoformed packaging is used across a broad range of industries. Here's where we most commonly apply PETG in production:
Medical Device Packaging
PETG is widely used in medical device packaging because of its FDA compliance, sterilization compatibility, and ability to secure tightly around sensitive instruments and components. It maintains clarity for visual inspection without compromising the structural support medical packaging requires.
Retail and Consumer Product Packaging
For consumer goods heading to retail shelves, PETG provides the kind of clarity that makes product features visible through the packaging without yellowing, hazing, or cracking under typical handling and transit conditions. It's well-suited for clamshells, blisters, and display trays across personal care, electronics accessories, and hardware categories.
Industrial and Component Trays
PETG also performs well in production and shipping trays that help components stay organized and protected. Its rigidity at room temperature and impact resistance make it a practical choice for trays used in kitting, assembly, and transport environments.
Production Volumes Built for Manufacturers
Our facility is set up for customers with high-volume production demand. While we can accommodate lower-volume projects, our operations are optimized for orders of 50,000 units and above. At that scale, we can spread tooling costs more efficiently, maintain tighter consistency across the run, and keep lead times predictable.
Thin Gauge vs. Thick Gauge PETG
Both thin and thick gauge options are available in our PETG thermoforming work, and the choice between them affects more than just wall thickness.
- Standard for high volume retail or medical packaging such as clamshells and blisters
- Forms quickly, with clean detail while keeping material costs manageable for large quantities
- Used when packaging must bear heavier loads, support structural components, or hold its shape in more demanding conditions
We help customers work through gauge selection as part of the quoting process, factoring in product weight, cavity geometry, and end-use environment so the packaging performs the way it needs to.

Frequently Asked Questions About PETG Thermoformed Packaging
Is PETG safe for medical device and food contact packaging?
Yes. PETG is FDA-compliant for both food contact and medical device applications, which is one of the primary reasons it's widely used in PETG medical device packaging. It can also be sterilized using gamma radiation and ethylene oxide (EtO), depending on your specific compliance requirements. If you have specific requirements, share them during the quoting process so we can confirm the right grade.
What is the typical lead time for custom PETG packaging at FormTight?
Lead time depends on tooling complexity, order volume, and production scheduling at the time of your order. Tooling for a new custom PETG packaging program typically runs several weeks, followed by production. Customers with repeat orders or blanket programs generally see faster turnaround once tooling is in place.
Do you handle tooling in-house for PETG thermoforming projects?
Yes. Tooling is part of the production process, and we manage it as part of your overall project. When you're ready to start a new custom program, tooling design and fabrication are part of what we work through with you before production begins.
