Common Mistakes to Avoid

Underestimating Weight

Key Consideration: Double wall boxes support up to 50kg, but improper stacking or handling can cause failure.
Tip: Specify your product weight for reinforced corner options.

Wrong Flute Direction

Key Consideration: Incorrect flute orientation reduces compression strength by up to 40%.
Tip: Vertical flutes for stacking strength; horizontal for cushioning.

Ignoring Humidity

Key Consideration: Corrugated materials lose up to 60% strength in high humidity.
Tip: Request moisture-resistant coating for humid environments.

Poor Seal Quality

Key Consideration: Weak adhesive or tape causes package failure during transit.
Tip: Specify tape width and sealing method for heavy loads.

Frequently Asked Questions

What is the difference between single wall and double wall corrugated boxes?

Double wall corrugated boxes have two layers of corrugated medium between three sheets of linerboard, compared to single wall which has one layer between two sheets. This provides up to 3x the compression and stacking strength, making double wall ideal for heavy products and courier shipments.

What is the weight capacity of double wall boxes?

Our double wall corrugated boxes can support up to 50kg per box depending on the specific size and flute configuration. For very heavy items, we recommend reinforced corner options and specific flute orientations for maximum stacking strength.

What is the minimum order quantity?

MOQ is 500 pieces for standard sizes. For custom sizes, MOQ typically starts at 1,000 pieces. Sample orders of 5-10 pieces are available for quality assessment.

Can double wall boxes be printed with custom designs?

Yes, we offer offset printing, flexographic printing, and screen printing with CMYK, Pantone color matching. Finishing options include lamination (gloss/matte), foil stamping, spot UV, and soft-touch coating.

Are these boxes eco-friendly?

Yes, corrugated cardboard is 100% recyclable and made from renewable resources. FSC-certified materials are available upon request. We also offer water-based inks and biodegradable moisture-resistant coatings.

What is the production lead time?

Standard production takes 10-15 working days. Sample production is 5-7 days. Rush orders (7-10 days) are available with 15-20% surcharge.

How does the fold-flat design save shipping costs?

Our double wall boxes ship flat and assemble on-site, reducing shipping volume by up to 70% compared to pre-assembled boxes. This significantly lowers freight costs, especially for international shipping.
