MinnTech PlasticsRecyclable Thermoformed Packaging Materials
RPET and CPET — three #1 PET recyclable materials engineered for performance and recovery.
MinnTech Plastics manufactures thermoformed packaging from three recyclable PET based materials: RPET (Recycled PET) and CPET (Crystallized PET). Each carries the #1 recycling code the most widely collected and reprocessed plastic resin in the United States. Whether your brand priorities are curbside recyclability with post consumer recycled content, or high heat ovenable performance, our recyclable material portfolio delivers both functional performance and verifiable end of life recovery.
RPET — Recycled APET for Clear, Recyclable Packaging
RPET is a crystal clear, rigid thermoplastic manufactured from post consumer recycled PET, primarily sourced from recovered water bottles and food containers. By specifying RPET for your thermoformed packaging, you directly reduce demand for virgin petroleum based plastic resin and support the circular economy. RPET provides exceptional optical clarity for clamshells, lids, and display packaging while maintaining the same #1 PET recyclability — meaning RPET packaging can be collected, recycled, and converted into new RPET products in a closed loop cycle.
- Excellent optical clarity for retail product visibility
- Can contain verified post consumer recycled content from recovered PET
- Maintains full #1 PET recyclability after use for multiple recycling cycles
- Reduces demand for virgin plastic resin production by displacing petroleum based inputs
- Supports circular economy goals and substantiates brand sustainability claims
CPET — Crystallized PET for High Heat Applications
CPET is a semi crystalline form of PET engineered for high temperature performance. It withstands oven temperatures up to 400°F (204°C), making it the material of choice for ovenable trays, bakeable containers, and dual oven packaging. While CPET carries the same #1 PET resin code as RPET, its crystallized molecular structure makes it opaque and denser than amorphous PET. This density difference means CPET is typically processed through industrial recycling streams using density based sorting rather than standard curbside collection.
- #1 PET recyclable through industrial recycling programs and commercial MRFs
- Heat resistant up to 400°F (204°C) for ovenable and bakeable applications
- Crystallized structure requires density based sorting (not standard curbside NIR)
- Fully recoverable through commercial PET recycling facilities equipped for dense PET
Choosing the Right Recyclable Material
Selecting between RPET and CPET depends on your product requirements, consumer disposal infrastructure, and brand sustainability goals. For maximum consumer recyclability, RPET offer curbside acceptance in over 90% of U.S. programs. For post consumer recycled content claims, RPET provides verified documentation. For ovenable and heat seal applications, CPET delivers high temperature performance with industrial recyclability. MinnTech’s packaging engineers work with your team to match the right material to your specific application and sustainability targets.
- RPET: Ideal for clear, curbside recyclable clamshells and retail display packaging with post consumer recycled content
- CPET: Required for oven safe trays and packaging that encounters high temperature processing

Frequently Asked Questions
Is thermoformed PET packaging recyclable?
Yes. All PET based thermoformed packaging from MinnTech Plastics (RPET and CPET) carries the #1 PET resin identification code and is recyclable. RPET are accepted in most U.S. curbside recycling programs, while CPET is recovered through industrial recycling channels due to its higher density from crystallization.
What is the difference between RPET and CPET?
RPET is manufactured from post consumer recycled PET and offers crystal clarity for retail display while providing verified recycled content for sustainability claims. CPET is a crystallized PET engineered for high temperature performance up to 400°F. Both are #1 PET recyclable, with RPET accepted in curbside programs and CPET recovered through industrial recycling.
How does using RPET support sustainability?
Specifying RPET directly reduces demand for virgin petroleum based resin by replacing it with material recovered from the post consumer waste stream. This lowers the carbon footprint of packaging production, diverts PET from landfills, and supports the circular economy by keeping plastic material in productive use. RPET maintains full recyclability, so the material can be recycled again after use.
