Best Sheet Materials for Fresh Produce Packaging: Why APET & RPET Lead the Market

Choosing the right plastic sheet for fruit and vegetable thermoforming trays and clamshells is becoming increasingly important, especially as global retailers push for better product freshness, high clarity, environmental responsibility, and material cost-efficiency. When it comes to fresh produce packaging, APET and RPET sheets stand out as the most reliable and widely used materials—offering the perfect balance of performance, transparency, safety, and sustainability.

At DESU, we specialize in producing APET / RPET thermoforming sheets, including single-sided and double-sided silicone-coated PET sheets, designed specifically for high-speed thermoforming and automated packing lines. This guide will help you understand which material is the best fit for your fruit and vegetable packaging application.

What Makes a Material Suitable for Fruit & Vegetable Thermoforming Trays?

Fresh produce packaging requires a material that meets several performance demands. A suitable sheet material should include:

• High transparency for premium product visibility
• Good impact resistance to protect delicate produce
• Excellent stiffness for clamshell structures
• Reliable sealing performance
• Food-grade safety compliance
• Cost-effective and recyclable
• Compatible with high-speed thermoforming machines

Among all plastic sheet materials available on the market—PP, PS, PLA, PVC, PET—APET and RPET consistently rank as the top two choices for fruits and vegetables.

Why Silicone-Coated PET Sheets Are Important for Thermoforming Produce Trays？

In high-speed thermoforming lines, PET sheets without surface treatment may suffer from:

• Sticking to molds
• Poor demolding performance
• Surface scratches
• Static dust problems

To solve these issues, DESU offers:

Single-Sided Silicone Coated PET Sheet

• Recommended for standard thermoforming lines
• Prevents sheet sticking
• Reduces mold wear
• Improves smoothness

Double-Sided Silicone Coated PET Sheet

Best for:

• High-speed automatic thermoforming machines
• Complex clamshell structures
• Precision hinges and locking tabs

Benefits of Silicone Coating:

• Better mold release
• Higher production efficiency
• Lower defect rate
• More consistent thickness distribution
• Smooth surface finish
• Prevents film sticking during stacking

Whether you choose APET or RPET, silicone coating can significantly improve manufacturing performance.

When selecting sheet materials for fruit and vegetable thermoforming trays and clamshells, APET and RPET are the industry’s most reliable, sustainable, and cost-effective choices. Their clarity, mechanical strength, safety, and recyclability make them ideal for modern fresh produce packaging.

If you require even smoother production, single-sided or double-sided silicone-coated PET sheets can greatly improve efficiency and forming quality.

Why APET and RPET Dominate Fresh Produce Packaging

Both APET and RPET offer the best balance of clarity, strength, and food safety.
They are widely accepted in global markets and perform well in cold-chain environments, making them the most reliable materials for fruit and vegetable packaging.

Final Recommendation

For high-end retail packaging, APET is the best choice due to its superior clarity and presentation.
For environmentally conscious brands and cost-sensitive projects, RPET provides a strong and sustainable alternative.
