Why Bincai
Unlike trading companies that source from third-party factories, Bincai owns the entire production chain. Our in-house corrugator lets us control board quality from the first flute — no middlemen, no markup, no quality uncertainty. We run B-flute, C-flute, E-flute, and BC double-wall on-demand, with white top kraft liners for photo-quality print on brown board. Most mailer suppliers take 3-4 weeks; our integrated factory delivers in 10-15 working days. For e-commerce brands scaling fast, our 1.7M daily capacity means we keep up when your order sizes jump from 5K to 500K overnight.

- Flat-packed shipping reduces transport carbon footprint by up to 60% vs assembled boxes
- 100% recyclable corrugated board — single-stream recycling compatible, no plastic lamination
- White top kraft liners are bleach-free and produced with closed-loop water systems
- Digital sample proofing eliminates physical sample waste for design iterations
FAQ
Q: What’s the difference between B-flute and E-flute for mailers?
A: B-flute (~3mm thick) offers the best crush resistance for heavier products and stacking. E-flute (~1.5mm) is thinner with a smoother surface — ideal for high-quality print and lighter items. BC double-wall combines both for maximum protection on fragile goods.
Q: Can I print inside the mailer?
A: Yes. Inside printing on the kraft liner is a signature Bincai capability — perfect for surprise branding, social media prompts, or care instructions that customers discover during unboxing.
Q: What’s the minimum order for a new brand?
A: MOQ is 500 units — designed for DTC startups testing new packaging. We also offer 100-unit trial runs for design validation before committing to full production.
Q: How fast can you deliver custom samples?
A: Pre-production digital samples in 24 hours. Physical samples (with printing and die-cutting) in 5-7 working days via DHL or FedEx. Rush service available for time-sensitive launches.
Q: Do you offer fulfillment-ready packaging with barcodes?
A: Yes. We can integrate FNSKU barcodes, QR codes, batch numbers, and Amazon-compliant labeling directly into the print — your mailers arrive warehouse-ready.
