In the past 5 years of experience in the packaging industry, the most common question that customers ask when ordering their mailer boxes is “How much do custom mailer boxes cost?” The honest answer is: it depends.
Unlike stock boxes, they don’t come with a fixed price. Their pricing depends on various factors, which include size, material, print, finishes, quantity, and mailer box type.
Once you understand what drives your price, you can start making smart choices that can reduce your per-unit cost without compromising quality.
Before I begin to break down the cost, let’s give you an overview of what mailer boxes are.
What are Mailer Boxes?
Mailer Boxes are specialized containers that are designed to ship luxurious and delicate ecommerce and retail products. They are made from durable materials that help absorb shocks and prevent damage during transit.
These boxes also provide a secure fit for products, helping businesses maintain product quality, improve customer experience, and create a professional unboxing presentation.
Average Cost Of Mailer Boxes
Standard kraft or cardboard mailer boxes usually range from $0.40 to $1.50 per unit when ordered in bulk. Premium or fully customized mailer boxes with inserts, foil stamping, embossing, or specialty coatings can cost $2 to $5+ or more per box.
Ordering larger quantities significantly reduces the per-unit price, making custom mailer boxes more cost-effective for growing ecommerce and retail businesses.

Now that you know what mailer boxes are and their average cost, let’s understand the factors that affect their pricing.
7 Factors That Determine Mailer Box Pricing
There are various factors that affect the mailer box pricing. I have listed the main 7 factors below:
- Material & Flute Type
- Size & Dimensions
- Printing & Color Coverage
- Finishes
- Inserts & Dividers
- Sustainability/Material Grade
- Quantity
Material & Flute Type
The material you select for your custom mailer boxes significantly affects your pricing, as it forms the foundation of the packaging. The material options available for mailer boxes are:
Cardboard:
Cardboard is a lightweight yet durable option for shipping lightweight retail and ecommerce items. Cardboard is popular for its printable surface, which allows artwork to be printed in vibrant colors.
Not only that, but cardboard also comes in various thicknesses depending on the weight of the product you want to store. The thickness of cardboard ranges from 14pt to 24pt.
Corrugated Cardboard
Corrugated cardboard is a durable material made from two linerboards and wavy flutes that provide safe shipping for lightweight, medium-weight, and heavyweight retail and ecommerce products. The linerboards are mostly referred to as paperboard, cardboard, or kraft paperboard, which is used as a printing surface for the artwork. The wavy flute between two linerboards helps absorb shocks during shipment.
There are various flute options that depend on the product you want to store in your boxes:
- A-Flute: Provides maximum cushioning and is ideal for fragile or heavy products.
- B-Flute: Offers excellent stacking strength and is commonly used for retail packaging.
- C-Flute: Balances protection and printing quality, making it suitable for general shipping boxes.
- E-Flute: Features a thin profile with a smooth surface for high-quality printing and lightweight products.
- F-Flute: Provides a premium appearance and is often used for luxury and specialty packaging.

Note: For custom mailer boxes, the most suitable flute type is either E-flute (1/16″) or B-flute (1/8″).
Size & Dimensions
The size and dimensions of your custom mailer boxes directly affect pricing, as larger boxes require more material for production. Bigger boxes also increase printing, shipping, and storage costs.
Choosing a box that closely matches your product dimensions helps reduce material waste and keep packaging costs under control while still providing adequate protection during shipping and handling.

Printing & Color Coverage
Printing and color coverage affect pricing because full-color designs use more ink and require longer production time. Simple one-color printing is generally more affordable, while edge-to-edge artwork, gradients, and detailed graphics increase the overall cost.
Choosing the right print coverage helps balance branding and budget.
Finishes
Finishes such as matte lamination, gloss coating, spot UV, embossing, and foil stamping add a premium look to custom mailer boxes.
Each finishing option requires additional production steps and materials, which increases the price. Basic coatings are more economical, while specialty finishes cost more.
Inserts & Dividers
Custom box inserts and cardboard packaging dividers increase pricing because they require additional material and die-cutting. They help secure products during shipping and improve presentation, especially for fragile or multiple-item packaging. The more complex the insert design, the higher the production cost.
Sustainability / Material Grade
Sustainable and higher-grade materials can affect the price of your custom mailer boxes. Recycled kraft stock is often cost-effective, while premium eco-friendly or certified materials may be more expensive. The material grade you choose affects durability, print quality, and overall packaging costs.
Quantity
Quantity has a major impact on pricing because larger orders reduce the cost per box. Setup, printing, and production expenses are spread across more units, making bulk orders more economical. Smaller quantities usually have a higher per-unit price due to fixed manufacturing costs.
