FAQ

Q: What makes this corrugated thermal mailer better than a foam (EPS) cooler for pharmaceutical shipping?

A: Three key advantages: (1) Flat-packed storage — our corrugated mailers ship flat and are folded into shape at the packing station, saving 70%+ warehouse space versus rigid EPS coolers; (2) Sustainability — corrugated with metallized PET liner is fully recyclable in the paper stream (customers simply separate the liner), versus EPS which is rarely recycled and persists in landfills for centuries; (3) Customization — corrugated boxes accept full CMYK printing for branding and regulatory labeling, while EPS is limited to applied labels. For weight, our double-wall configuration is 40% lighter than equivalent EPS, reducing freight costs.

Q: How do you validate the thermal performance — can you provide ISTA 7D test reports?

A: Yes — every thermal configuration (liner thickness + gel pack quantity + payload mass) is validated per ISTA 7D protocols at an accredited third-party testing laboratory. We provide full test reports showing internal temperature profiles at 15-minute intervals for the entire test duration. Standard configurations are pre-validated and reports are included with your order documentation. For custom configurations (unique payload mass, unusual external dimensions, or extended duration requirements), we conduct a validation test with your product simulant as part of the sampling process — typically 14-21 days for test completion and report delivery.

Q: Can this mailer be used for frozen (-20°C) shipping as well as refrigerated (2-8°C)?

A: Yes — the same box construction supports frozen shipping with a different gel-pack configuration (phase-change material at -20°C instead of 2-8°C). For frozen shipping, we typically recommend 12mm thermal liner thickness and 6-8 gel packs for 48-hour protection, validated per ISTA 7D frozen profile. Note that frozen shipping is more demanding on the corrugated structure due to potential frost/condensation upon thawing — we upgrade the water-resistant adhesive and add a poly-coated exterior for frozen applications. Lead time for frozen qualification adds 7-10 days.

Q: What are the lead time, MOQ, and regulatory compliance considerations?

A: Standard lead time is 15-20 days for existing validated configurations and stock materials. Custom size requiring new die-board tooling adds 5-7 days. New ISTA thermal validation for custom payload adds 14-21 days. MOQ is 500 units for standard configurations, 1000+ for custom thermal liner or new ISTA validation. Our facility is ISO 9001:2015 certified with full batch traceability — GDP (Good Distribution Practice) documentation package available including: certificate of conformance per batch, ISTA 7D test reports, material certificates (board, liner, adhesive), and chain-of-custody documentation. We also support 21 CFR Part 11 compliant electronic documentation for FDA-regulated products. MOQ 500 units. ISTA 7D thermal validation reports, liner samples, and gel-pack configuration guides available. Sample within 5 days. Lead time 15-40 days (depending on validation requirements).
