Custom Duplex Boxes for Premium Product Packaging
Duplex board combines two layers of paperboard into a single sheet, creating packaging that balances strength with printability. At Teal Packaging, we manufacture custom duplex boxes with white-coated surfaces on one or both sides, ideal for retail products that need sharp graphics and structural integrity. Our duplex boxes work well for cosmetics, electronics, food items, and gift packaging where presentation matters as much as protection.
The duplex construction process bonds a bleached white kraft layer to a gray or kraft backing, resulting in a smooth printing surface with solid structural support. This two-layer approach costs less than solid bleached sulfate (SBS) board while delivering comparable visual results for most applications. The white coating accepts offset printing, digital printing, and specialty finishes like spot UV, foil stamping, and embossing. For related packaging needs, explore our corrugated packaging.
Material Specifications and Board Weights
We stock duplex board in weights from 250 GSM to 450 GSM, covering most product packaging needs. The 250-300 GSM range suits lightweight items like cosmetics, candles, and small electronics. For heavier products or boxes requiring more rigidity, 350-450 GSM duplex provides the necessary strength without excessive bulk. All our duplex board comes from mills certified for responsible forestry practices.
The white coating on duplex board typically measures 18-24 point thickness, providing a bright surface that reproduces colors accurately. The gray backing doesn't show through unless you score or cut the material, making it suitable for full-bleed designs. For applications where both sides need white coating, we offer duplex with white on both faces at a slight premium over standard single-coated board.

Box Styles and Construction Options
Our duplex boxes come in several standard configurations:
- Reverse tuck end boxes with opposing flaps for easy assembly
- Straight tuck end boxes where both flaps insert from the same side
- Auto-lock bottom boxes that snap together without glue or tape
- Sleeve and tray boxes with separate outer sleeves
- Window boxes with PET or PLA film panels
- Gable boxes with carrying handles for gift packaging
Each style serves different product types and retail display needs. Reverse tuck boxes work well for products that load from either end. Auto-lock bottoms speed up packaging lines by eliminating bottom sealing steps. Sleeve boxes create premium unboxing experiences with two-piece construction.
Printing and Finishing Capabilities
The white-coated surface of duplex board accepts both offset and digital printing methods. Offset printing delivers the best color accuracy and consistency for runs over 500 units, while digital printing works well for smaller quantities or variable data applications. We print in full CMYK process color, with options for Pantone spot colors when brand matching requires precise shades.
Finishing options include:
- Aqueous coating for basic scuff resistance
- UV coating in gloss or matte for enhanced durability
- Spot UV highlighting specific design elements
- Foil stamping in metallic or holographic finishes
- Embossing or debossing for texture and depth
- Die-cut windows or custom shapes
Combining multiple finishes creates distinctive packaging that stands out on retail shelves. A common approach pairs matte coating with spot UV gloss on logos or product images, creating contrast that draws the eye.
Pricing Structure and Minimum Orders
Our duplex box pricing follows quantity-based tiers that reflect setup costs and material efficiency:
- 100 units: $3.80-$5.20 per box depending on size and finishing
- 500 units: $2.10-$3.40 per box with better material utilization
- 1,000 units: $1.50-$2.60 per box at full production efficiency
Minimum order quantity is 100 units for all custom duplex boxes. Prices include full-color printing and one standard finish (aqueous or basic UV coating). Additional finishes like foil stamping or embossing add $0.40-$1.20 per box depending on coverage area. Window cutouts with film add approximately $0.30 per box for material and labor.
Complex die-cut shapes or unusual box dimensions may require custom tooling, which adds a one-time setup fee of $180-$320 to the first order. Subsequent reorders using the same die don't incur this fee. We store dies for up to two years at no charge.
Production Timeline and Shipping
Standard production time for custom duplex boxes runs 15-20 business days from approved artwork. This includes prepress work, printing, die-cutting, folding, and quality inspection. Rush production is available for 30% additional cost, reducing turnaround to 10-12 business days. For related packaging needs, explore our eco-friendly kraft boxes.
We ship from our New York facility via UPS, FedEx, or freight carrier depending on order size. Orders under 500 units typically ship via UPS Ground. Larger orders may ship on pallets via freight for better rates. Shipping costs vary by destination and order weight, usually adding $85-$240 for East Coast delivery and $180-$420 for West Coast destinations.
Design Guidelines and Artwork Requirements
For best results, supply artwork as vector PDF files with fonts outlined and images embedded at 300 DPI minimum. Set up your design with 0.125 inch bleed on all sides and keep important text or graphics at least 0.25 inch from cut lines and score lines. Use CMYK color mode rather than RGB to ensure accurate color reproduction.
We provide dieline templates for all standard box sizes. If you're working with a designer, send them our template before starting the design to ensure proper fit. Our prepress team reviews all artwork for production issues and contacts you if adjustments are needed before printing.
Quality Control and Material Testing
Every duplex box order goes through multiple quality checkpoints. We verify board thickness and coating quality when material arrives from the mill. During printing, we check color accuracy against approved proofs every 500 sheets. After die-cutting, we inspect samples for clean cuts and proper scoring. Final inspection before shipping confirms accurate counts and checks for any printing defects.
For products with specific performance requirements, we can arrange crush tests, drop tests, or moisture resistance testing. These tests add 3-5 days to the production schedule but provide documented evidence of box performance under various conditions.
Getting Started with Your Order
To begin your custom duplex box project, request a quote with your dimensions, quantity, and any specific finishing requirements. We'll provide pricing within one business day and can send physical samples of similar boxes to evaluate material quality and printing capabilities. Our production team is available to discuss technical requirements and recommend the best approach for your specific products.
