From concept to production — MinnTech Plastics engineers thermoformed packaging using RPET, APET and CPET to meet your product's performance, sustainability, and cost targets.
MinnTech Plastics provides end to end thermoformed packaging design services — combining engineering expertise with materials knowledge to create packaging that protects products, performs on automated lines, and meets increasingly ambitious sustainability targets. Whether you need a single cavity clamshell or a complex multi compartment meal tray or platter, our design team works from your product specifications to deliver high quality thermoformed part.
Minn Tech packaging design process overview.
Design & Engineering
Every thermoformed package begins with a concept. MinnTech's engineering team translates product dimensions, stacking requirements, and filling line constraints into production ready tooling designs — balancing material efficiency with real world performance.
Stacking & Nesting Geometry
Packages are designed for efficient stacking in storage and transport. Anti nesting features prevent trays from locking together during denesting on automated filling lines, reducing downtime and product damage.
Seal Surface & Lid Compatibility
Flat, consistent flange surfaces are critical for heat seal and snap fit lid applications. Our designs ensure the seal area remains dimensionally stable across production runs, providing reliable tamper evidence and leak resistance.
Material Selection & Optimization
Choosing the right thermoforming material is the single most impactful decision in packaging design. MinnTech evaluates each project against mechanical, thermal, optical, and sustainability criteria to recommend the optimal resin — whether that's crystal clear RPET for retail, APET for freezer applications, or dual ovenable CPET for prepared meals.
Performance Driven Resin Selection
We match material properties to end use requirements: impact resistance for shipping, clarity for point of sale display, heat tolerance for microwave or oven reheating, and chemical resistance for industrial applications.
Gauge Optimization & Lightweighting
Through iterative prototyping design, we identify the minimum gauge that meets performance specs reducing raw material cost per unit and lowering the package's environmental footprint without sacrificing structural integrity.
Multi Compartment Tray Design
Multi compartment trays are among the most technically demanding thermoformed products. MinnTech specializes in designing trays that separate foods, control portions, and perform on high speed packaging lines from dual compartment meal containers to five section snack trays.
Compartment Separation & Leak Control
Internal divider walls are engineered with sufficient height and material distribution to prevent cross contamination between wet and dry thinning during forming.
Portion Control Geometry
Volumetric accuracy matters for regulatory compliance and consumer expectations. Each compartment is designed to hold a target fill volume, with cavity dimensions validated against prototype measurements before tooling approval.
Automated Line Compatibility
Trays are designed for seamless integration with automated filling, sealing, and labeling equipment. Registration features, consistent flange widths, and denesting tabs ensure reliable throughput on high speed lines.
Sustainability Driven Packaging Design
Sustainability is not an afterthought at MinnTech, it's a core design parameter. We can integrate curbside recycled content materials, design for recyclability principles, and lightweighting strategies into every project, helping customers meet environmental commitments without compromising performance.
Recycled Content Materials
MinnTech Plastics offers 25% to 50% post consumer recycled content options for our customers. RPET sheet with post consumer recycled content delivers the same clarity and formability as virgin PET, helping brands meet sustainability commitments and recycled content mandates.
Design for Recyclability
Our packaging is designed to be compatible with existing curbside recycling infrastructure. We avoid problematic colorants, labels, and multi material constructions that can contaminate recycling streams, helping ensure our packages enter the recycling process cleanly.
Source Reduction & Material Efficiency
Every gram of material removed from a package compounds across millions of units. Our lightweighting process systematically reduces gauge and optimizes geometry to minimize resin consumption while preserving the performance envelope.
Thermoforming Material Comparison
The table below summarizes key properties of the five thermoforming materials MinnTech works with — helping you narrow the right resin for your application before the design phase begins.
| Material | Clarity | Heat Resistance | Recycled Content | Recyclable | Best For |
|---|---|---|---|---|---|
| APET | Excellent | Moderate (120 °F) | Virgin | Yes (#1 PET) | Freezer packaging, retail clamshells |
| RPET | Excellent | Moderate (120 °F) | 25%–50% PCR | Yes (#1 PET) | Sustainability focused retail, deli containers |
| CPET | Opaque | High (400 °F) | Virgin / Recycled | Yes (#1 PET) | Dual ovenable meal trays, airline catering |

Packaging Design FAQs
Common questions about MinnTech's thermoformed packaging design services.
MinnTech thermoforms with RPET and CPET. RPET provides crystal clarity for retail display with 30–100% post consumer recycled content. CPET is oven safe for dual ovenable meal trays. Both materials are Category #1 PET recyclable.
Yes — multi compartment tray design is a core specialty. We engineer precise compartment separation, portion control geometry, and leak resistant sealing surfaces, all optimized for stacking, lidding, and automated filling lines.
A typical design engagement begins with a consultation and CAD review, followed by 3D printed prototype samples within 2–4 weeks. Production tooling and first production runs are typically completed within 8–12 weeks, depending on design complexity and material requirements.
Absolutely. Sustainability is built into every design engagement. We offer recycled content RPET with up to 100% post consumer material, lightweighting strategies to reduce material usage, and design for recyclability consulting to ensure packages meet current recycling infrastructure standards.
MinnTech designs thermoformed packaging for food and beverage, medical device, retail consumer products, electronics, and industrial applications. Our engineering team adapts material specs, barrier properties, and structural requirements to each industry's regulatory and performance standards.
