Standard production takes 10-25 business days after design approval and deposit payment. This includes die-making, printing, cutting, and quality inspection. Rush orders can be accommodated in 10-12 days with express fees. Shipping time depends on your location: 3-5 days by air express, 25-35 days by sea freight from Shenzhen port.

Yes! We provide free blank samples (similar size/material) within 3 days. For printed samples with your artwork, there's a setup fee of $80-150 (refundable with production order), ready in 5-7 days. We also offer digital 3D mockups for initial approval. Samples can be shipped worldwide via DHL/FedEx/UPS.

Absolutely. All our cardboard is recyclable and biodegradable. We offer FSC-certified materials sourced from sustainably managed forests (available upon request with additional certification fees). We use water-based inks for printing, which are non-toxic and environmentally safe. Recycled content options (30-100% post-consumer waste) are available for clients prioritizing circular economy principles. Our production process minimizes waste, and all scraps are recycled.

Yes! We offer both plain digital samples (for sizing check) and finished production samples (for print quality check). Sample fees are typically refundable against mass production orders.

Yes. Bundling, stretch wrap, corner protection, and pallet packing can be arranged based on your warehouse receiving standards and container loading plan.

We optimize structure, board construction, and internal protection (dividers/pads). If you have damage photos or carrier data, we can adjust the design to improve performance.

Packaging Knowledge Base

Expert insights to help you make informed packaging decisions

Understanding Corrugated Board Grades

Flute Types:

  • A-Flute (5mm): Excellent cushioning and stacking strength. Ideal for fragile items.
  • B-Flute (3mm): Good puncture resistance and printability. Perfect for retail displays.
  • C-Flute (4mm): Most common; balances strength and cost. Great for general shipping.
  • E-Flute (1.5mm): Thin profile with excellent printability. Used for retail packaging.
  • Double Wall (AB, BC): Heavy-duty applications requiring maximum protection.

How to Calculate Box Strength Needed

Step-by-step guide:

  1. Product Weight: Measure total weight including contents and cushioning.
  2. Stacking Height: Determine maximum warehouse stacking (typically 5-8 boxes high).
  3. ECT Rating: Multiply product weight by stacking factor (6-8x for safety margin).
  4. Environmental Factors: Consider humidity, temperature, and transit duration.
Example: 10kg product, stacked 6 high = minimum 32 ECT required (10kg × 6 × 1.2 safety factor ÷ 2.25 conversion)

Sustainability & Recycling

Corrugated cardboard is one of the most recycled materials globally, with recovery rates exceeding 90% in developed markets.

Environmental Benefits:

  • Made from renewable resources (wood fiber)
  • Biodegradable and compostable
  • Requires 75% less energy than plastic production
  • Can be recycled 5-7 times before fiber degradation
  • Carbon footprint 3x lower than plastic alternatives

Optimizing Shipping Costs

Key strategies to reduce expenses:

  • Right-sizing: Custom boxes eliminate wasted space and reduce dimensional weight charges (up to 30% savings).
  • Material Selection: Use lightest board grade that meets strength requirements.
  • Nested Designs: Boxes that stack inside each other save storage and transport costs.
  • Pallet Optimization: Design boxes to maximize pallet utilization (standard 48"×40").
  • Regional Production: Our Shenzhen location offers proximity to major Asian ports, reducing lead times.
