1. Food safety compliance: Ensure the PET is food-grade, BPA-free, and certified to meet target market standards (GB 4806.7, EU 10/2011, FDA 21 CFR 177.1630). Ask for test reports and batch traceability.
2. Material quality: Opt for virgin PET or certified PCR PET with consistent clarity, no odor, and good rigidity. Avoid recycled PET with unknown sources or inconsistent color.
3. Clarity & anti-fog: For retail appeal, choose high clarity (>90% transmittance) and anti-fog coating if used in cold environments.
4. Structural strength: Check impact resistance, stackability, and low-temperature performance (especially for cold chain use). Reinforced corners and ribs improve durability.
5. Ventilation design: Select appropriate vent hole size and pattern for your fruit type—more airflow for berries, less for stone fruits.
6. Size & weight capacity: Choose exact dimensions and weight ratings (100g, 250g, 500g, 1kg) to avoid overpacking or underutilization.
7. Closure security: Ensure snap-fit or hinged lids close tightly, resist popping open during transit, and offer tamper evidence.
8. Sustainability features: Look for PCR content options, recyclability, and minimal material usage (lightweighting).
9. Customization capability: If branding is important, verify the supplier offers printing, embossing, tinting, and custom mold services with reasonable MOQs.
10. Supplier reliability: Evaluate production capacity, lead times, quality control processes, and after-sales support. A stable supplier avoids delays and quality issues.
By prioritizing these factors, buyers can select PET fruit boxes that balance quality, safety, presentation, compliance, sustainability, and cost in 2026.
