| Ventilated Corrugated Fiberboard Tray | Kraft paperboard, commonly 3-ply or 5-ply corrugated board | 250–500 g produce packs; stackable open-top tray | 3–8% | Moderate; paper strength decreases as moisture increases | Approximately 35–55% | Single-use; recyclable when clean and dry | Apples, pears, citrus, stone fruit, mushrooms | Condition at 0–4°C and 90–95% RH for 24–72 hours; measure edge-crush strength, box compression, wet strength, and vent blockage. |
| Moisture-Resistant Corrugated Tray | Corrugated fiberboard with water-resistant coating or sizing | 250–1,000 g packs; reinforced stacking design | 4–10% | Moderate to good, depending on coating and edge protection | Approximately 50–70% | Single-use; recyclable subject to coating and local systems | Berries, grapes, cherries, tomatoes, leafy vegetables | Verify Cobb water absorptiveness, edge-crush strength, box compression, coating adhesion, and recycled-fiber compatibility. |
| Molded Pulp Produce Tray | Recycled cellulose fiber or molded agricultural-fiber pulp | 6–30 cavities; molded cushioning pockets | 2–7% | Low to moderate unless treated; fiber softening can occur at high RH | Approximately 40–65% | Usually single-use; recyclable or compostable depending on additives | Eggplant, peaches, pears, apples, delicate stone fruit | Measure moisture absorption, dimensional change, compression strength, pulp odor, surface cleanliness, and migration suitability for the intended market. |
| Ventilated PP Plastic Tray | Food-contact polypropylene, injection-molded or thermoformed | 250–1,000 g packs; nesting or stackable designs | 8–20% | Very high; negligible water absorption | Approximately 90–100% | Reusable; commonly suitable for multiple distribution cycles | Berries, grapes, tomatoes, mushrooms, leafy greens | Test stack load, hinge or snap durability, impact resistance at 0–4°C, food-contact compliance, washability, and nest-to-stack ratio. |
| rPET Clamshell or Ventilated Tray | Recycled polyethylene terephthalate with food-contact grade where required | 125–500 g hinged or lidded packs | 5–15% | Very high; low moisture absorption | Approximately 85–98% | Generally single-use; recyclable where collection infrastructure exists | Strawberries, blueberries, raspberries, cherries, cut produce | Check hinge-cycle performance, lid closure, top-load compression, condensation drainage, optical defects, and recycled-content documentation. |
| PET Produce Tray with Absorbent Pad | Clear PET tray with separate food-contact absorbent insert | 200–750 g packs; shallow cavity format | 4–12% | High for tray; pad capacity must be validated separately | Approximately 85–98% | Usually single-use; recycling depends on pad and material separation | Mushrooms, berries, cut vegetables, high-respiration produce | Validate liquid-holding capacity, pad integrity, odor transfer, condensation control, seal performance, and product-contact compliance. |
| Reusable HDPE Pool Tray | High-density polyethylene, rigid washable design | 5–15 kg bulk produce; returnable distribution format | 5–15% | Very high; low water absorption and good wash resistance | Approximately 90–100% | Multiple cycles when inspected and sanitized | Apples, citrus, melons, peppers, leafy vegetables | Test repeated stacking, drop impact at 0–4°C, wash-cycle durability, microbial-cleanability, label removal, and dimensional compatibility with pallets. |
