FAQ
Q: What’s the difference between double-wall and triple-wall corrugated?
A: Double-wall has two flute layers (typically C+B) at 6-8mm thickness, suitable for 15-30kg loads with ~150 PSI burst. Triple-wall adds a third flute (B/C/B) at 10-15mm, handling 40-60kg with 275+ PSI burst and 2× the stacking strength. Choose triple-wall for ocean freight LCL where boxes are stacked 5-6 high for 4-6 weeks.
Q: Can you print my Amazon FNSKU barcodes on the box?
A: Yes — flexo post-print handles barcodes, logo, handling instructions (“This Way Up”, “Fragile”), and FNSKU labels directly on the kraft liner. We recommend white-top liner for maximum barcode contrast and FBA scan reliability.
Q: Do you offer UN-certified packaging for dangerous goods?
A: Yes — we manufacture UN 4G fiberboard boxes for Packing Groups I, II, and III. Testing includes stacking, drop, and Cobb (water absorption) per IATA/IMDG regulations. Lead time for UN-certified production adds 5-7 days for third-party lab testing.
Q: What’s your minimum for custom die-cut corrugated designs?
A: 500 units for standard RSC designs with flexo print. Custom die-cut shapes (self-locking bottom, display windows, retail-ready PDQ trays) require 1,000+ units to amortize the rotary die tooling (~200-500 USD one-time). Sample blanks ship within 5 days.
