Why Choose Bincai for Heavy-Duty Corrugated Boxes

Frequently Asked Questions

Q: BC-flute vs. AB-flute — which one do I need? A: BC-flute (6-7mm, ECT 44+) handles most heavy e-commerce and industrial shipments up to ~25kg. AB-flute (8-9mm, ECT 55+) is for extra-heavy items (25-50kg), long-distance export, or high-stack warehouse storage. Our engineers evaluate your product weight, distribution channel, and stacking requirements to recommend the optimal flute.

Q: Can you print full-color graphics on a double-wall box? A: Yes — through litho-lamination. We print the artwork on coated art paper on our KBA 1050 or Heidelberg 7+1 UV press, then laminate it to the corrugated board. The result is a retail-quality printed box with the structural strength of double-wall corrugated. Flexo printing (1-3 colors) is also available for simpler designs.

Q: Do you offer Amazon FBA-compliant packaging? A: Yes. We design boxes to meet Amazon’s Frustration-Free Packaging (FFP) requirements, optimize dimensions for FBA storage tier rates, and can certify boxes as SIOC (Ships In Own Container). ISTA 6-Amazon.com testing available.

Q: What’s the difference between ECT and Mullen burst rating? A: ECT (Edge Crush Test) measures stacking strength — critical for warehouse and container stacking. Mullen burst rating measures puncture resistance — important for sharp or irregularly shaped contents. We specify both and recommend based on your supply chain conditions. For e-commerce, we prioritize ECT 44+ for stacking plus ISTA drop testing for impact.

Q: Can you add perforations or tear strips for easy opening? A: Yes. Perforated tear strips, rip-and-reveal panels, and easy-open features are standard options. For subscription boxes, we can create a “reveal” tear strip that doubles as a branding moment. For returnable e-commerce, double tear strips create a return-ready box.

Q: What’s your minimum order for custom-sized double-wall boxes? A: Standard MOQ is 500 units per size. For very large boxes (over 800×600×400mm), MOQ may be 300 due to board utilization. We also offer a sample run of 50-100 units for market testing before committing to full production.
