Types of Custom Corrugated Mailer Boxes
Corrugated mailer boxes are generally made from corrugated board consisting of a fluted paper layer between flat linerboards.
This structure provides cushioning and rigidity while allowing many mailer box designs to be shipped flat before assembly.
Different constructions can be selected according to your product, branding and distribution requirements.
1. Standard Corrugated Mailer Boxes
Standard mailer boxes, often called self-locking mailer boxes or roll-end tuck-front boxes, are among the most popular choices for ecommerce packaging.
They typically feature a hinged lid, a front tuck flap and side panels that fold into a secure box structure.
Common applications include:
- Clothing and fashion accessories
- Beauty and personal care products
- Promotional gifts
- Stationery and small merchandise
- Ecommerce orders
- Subscription products
Many standard mailer designs can be assembled without glue during the final packing process, although additional sealing may be necessary for shipment.
They are available in different sizes, board grades and printing styles.
2. Branded Ecommerce Mailer Boxes
Branded ecommerce mailer boxes turn ordinary shipping packaging into part of the customer experience.
Custom printing can be applied to the outside, inside or both surfaces of the box.
Popular branding options include:
- Full-color printed exterior designs
- Custom logos and brand colors
- Printed messages inside the lid
- Seasonal graphics
- Product illustrations
- QR codes and promotional information
- Coordinated packaging artwork
A printed message inside the box can create a memorable unboxing experience without requiring additional printed inserts.
For ecommerce brands, the packaging should also be practical for warehouse operations and product fulfillment.
3. Kraft Corrugated Mailer Boxes
Kraft corrugated mailer boxes have a natural brown paper appearance and are popular with brands that prefer simple, understated packaging.
Common options include:
- Natural brown kraft surfaces
- Black or white logo printing
- Simple one-color graphics
- Custom box dimensions
- Printed labels or sleeves
- Different corrugated board grades
Kraft mailers can be a practical option for promotional merchandise, gift collections and ecommerce products.
However, the environmental characteristics of the finished box depend on its actual paper composition, coatings, inks and other components.
If you need a smaller retail carton rather than a corrugated shipping box, explore our Custom Kraft Paper Boxes.
4. Corrugated Mailer Boxes with Custom Inserts
For products that need a more organized presentation or additional internal support, mailer boxes can be combined with custom inserts.
Possible insert options include:
- Folded corrugated inserts
- Paperboard dividers
- Die-cut product holders
- Molded pulp components
- Protective paper cushioning
- Selected foam inserts
- Custom compartments for gift sets
The right insert helps keep products in position and can improve the appearance of a multi-item gift collection.
For example, a corporate gift box may contain a notebook, pen, mug and other accessories, each held in a designated compartment.
We can also help coordinate the products inside through our Custom Corporate Gift Sets sourcing service.
5. Self-Sealing Corrugated Mailer Boxes
Self-sealing mailer boxes may include adhesive strips, tear strips or other features designed to simplify closing and opening.
These features can be useful for ecommerce fulfillment and repeated warehouse packing operations.
Depending on the design, they may offer:
- Faster sealing
- Reduced need for separate packing tape
- Convenient opening for customers
- A cleaner exterior presentation
- Optional return-sealing features on selected constructions
Not every corrugated mailer box includes self-sealing functionality.
Adhesive performance, sealing strength and opening features should be confirmed through sampling before bulk production.
6. Corrugated Handle Boxes
Corrugated handle boxes include an integrated carrying handle or a separate handle component.
They are often selected for promotional gifts, retail gift collections, event merchandise and selected product kits.
The handle may be formed through die-cutting or another suitable construction method.
When developing this style, consider:
- Total product weight
- Handle reinforcement
- Board strength
- Carrying comfort
- Box dimensions
- Intended transportation conditions
A carrying handle should be tested with the actual contents before confirming production.
Corrugated Board Materials and Thickness Options
The choice of corrugated board influences box strength, cushioning, printing quality, weight and cost.
Single-Wall Corrugated Board
Single-wall corrugated board consists of one fluted layer between two linerboards.
It is commonly used for many ecommerce mailer boxes and retail shipping applications.
Different flute profiles can be selected according to the required thickness and performance.
Double-Wall Corrugated Board
Double-wall corrugated board contains two fluted layers and three linerboards.
It may be considered for larger, heavier or more demanding packaging applications.
However, not every double-wall construction is necessary or suitable for a small ecommerce mailer.
White Corrugated Board
White-faced corrugated board provides a lighter surface for printing and branded presentation.
It can be useful for colorful ecommerce packaging and premium promotional boxes.
Kraft Corrugated Board
Kraft-faced corrugated board offers a natural brown appearance and is commonly used for simple branded mailers.
The actual paper grade and board construction should be confirmed with the manufacturer.
Printed Corrugated Board
Corrugated boxes can be printed using different processes depending on the required artwork, quantity and finish.
For detailed graphics, a printed surface sheet may be laminated to corrugated board, depending on the manufacturing method.
Understanding Corrugated Flute Types
Corrugated flutes are the wave-shaped paper structures inside corrugated board.
Different flute profiles provide different combinations of thickness, cushioning, stiffness and printing suitability.
| Flute Type | General Characteristics | Typical Considerations |
|---|---|---|
| E Flute | Relatively thin profile | Popular for printed retail mailers |
| B Flute | Thicker than E flute | Common for general protective packaging |
| C Flute | Larger flute profile | Used in many shipping carton applications |
| F Flute | Very fine profile | Suitable for selected compact printed packaging |
| Double-Wall Combinations | Two flute layers | May suit heavier or more demanding packaging |
Actual thickness and performance vary according to the board specification and manufacturer.
A thinner flute does not automatically mean the box is unsuitable for shipping, and a thicker flute does not guarantee adequate protection.
The complete box design, product weight, stacking conditions and distribution environment must be considered together.
Custom Printing Options for Corrugated Mailer Boxes
A corrugated mailer can be printed with anything from a simple logo to a detailed full-color brand design.
Full-Color Printing
Full-color printing is popular for subscription boxes, beauty brands, ecommerce products and promotional packaging.
It can be used to create colorful exterior designs and coordinated interior graphics.
Logo Printing
A simple one-color or two-color logo can create a recognizable branded box while keeping the design relatively straightforward.
This approach is especially popular for natural kraft mailers.
Inside Printing
Printing on the inside of the lid or interior panels can create a branded unboxing experience.
Common elements include thank-you messages, product instructions, promotional codes and brand storytelling.
White Ink on Kraft
White printing on brown kraft surfaces can create a distinctive visual contrast.
The appearance depends on the paper surface and printing process, so sampling is recommended.
Matte and Gloss Finishes
Selected printed corrugated packaging can incorporate matte or gloss surface treatments.
Availability depends on the board, printing method and finishing process.
Spot UV and Decorative Effects
Spot UV and other specialty finishes may be available for selected printed and laminated corrugated constructions.
These finishes should be confirmed with the manufacturer rather than assumed to be suitable for every board type.
Choosing the Right Mailer Box Size
Specify the required usable internal length × width × height for product fit, and label the units. External dimensions are different because they include the board and assembled structure. For parcel shipping estimates, measure the completed shipping package and its packed weight rather than using the internal box size.
An oversized mailer box can waste material, increase empty space and require additional protective filling.
A box that is too small may damage the product or make packing difficult.
Before finalizing the dimensions, consider:
- The actual length, width and height of the products.
- Whether several products will be packed together.
- The space needed for inserts or protective materials.
- The opening and closing structure.
- The thickness of the selected corrugated board.
- The required internal clearance.
- The dimensions of the packed shipping carton.
For multi-item projects, confirm the product arrangement, inserts and total packed weight before finalizing the dieline. Also confirm whether the mailer will be the outer shipping package or placed inside another carton, so the complete packing arrangement can be assessed.
Custom Inserts and Product Protection
An attractive mailer box should also protect its contents during normal handling and transportation.
Depending on the product, internal packaging may include:
Corrugated inserts: Folded or die-cut structures that help hold products in position.
Paperboard dividers: Useful for separating items within gift sets.
Molded pulp inserts: Suitable for selected product shapes and protective applications.
Paper cushioning: Can help fill empty spaces and reduce movement.
Foam inserts: May be considered for products requiring more precise support or cushioning.
Protective wraps: Additional wrapping may be necessary for fragile or scratch-sensitive surfaces.
The most suitable insert depends on product dimensions, fragility, weight and shipping conditions.
For fragile products, packaging performance should be assessed using realistic distribution conditions.
The International Safe Transit Association (ISTA) provides information about packaging testing and transport simulation standards.
A package should not be described as ISTA-tested or certified unless the applicable testing and documentation have actually been completed.
Corrugated Mailer Boxes vs. Folding Carton Boxes
Corrugated mailers and folding cartons can look similar in photographs, but their materials and intended uses are different.
| Feature | Corrugated Mailer Boxes | Folding Carton Boxes |
|---|---|---|
| Main material | Fluted corrugated board | Non-corrugated paperboard |
| Typical construction | Hinged mailer, self-locking or other corrugated structure | Tuck-end, auto-bottom and other folding structures |
| Main purpose | Shipping, ecommerce and protective presentation | Retail display and lightweight product packaging |
| Cushioning | Fluted structure offers some cushioning | Usually relies on board structure or additional inserts |
| Printing | Simple logo or full-color printed surfaces | Detailed retail graphics and specialty finishes |
| Storage | Many styles can be supplied flat | Many styles can be supplied flat |

Responsible Paper Sourcing and Recycling Considerations
Many buyers are interested in paper-based packaging, certified materials and reduced packaging waste.
Corrugated board is widely used in recyclable packaging systems, but the recyclability of a finished mailer box depends on its material composition and the recycling facilities available in the destination market.
Coatings, plastic components, adhesives and decorative finishes may influence recycling requirements.
For information about responsible sourcing of forest-based materials, visit the Forest Stewardship Council (FSC).
If your project requires FSC-certified paper or specific recycled-content documentation, these requirements should be discussed with the supplier before confirming the order.
We recommend evaluating:
- Paper and linerboard specifications
- Availability of certified materials
- Recycled-content requirements
- Printing inks and coatings
- Additional plastic components
- Protective inserts
- Destination-market recycling guidance
Environmental claims should reflect the actual product specifications and supporting documentation.
Wholesale Pricing and International Shipping Considerations
The cost of custom corrugated mailer boxes depends on the complete packaging specification.
Box Dimensions
Larger boxes require more board and may occupy more space during storage and transportation.
Board Grade and Flute Type
Different corrugated board constructions have different material costs and performance characteristics.
Printing Requirements
A simple printed kraft box may have a different cost structure from a fully printed, laminated mailer.
Custom Inserts
Die-cut inserts, dividers and protective components can add material and assembly costs.
Special Features
Self-sealing strips, tear strips, carrying handles and other structural details may require additional manufacturing steps.
Order Quantity
MOQ and unit pricing vary depending on the design, materials, printing method and manufacturer.
Flat-Pack Transportation
Many corrugated mailer boxes can be packed flat before assembly, helping reduce storage volume.
However, shipping costs should be calculated using the actual export carton dimensions, weight and shipment volume.
Before placing a wholesale order, confirm:
- Finished box dimensions
- Flat-packed dimensions
- Pieces per export carton
- Export carton dimensions
- Gross weight
- Total carton quantity
- Estimated shipment volume
- Assembly and sealing requirements
Comparing these details can help buyers understand the overall landed cost rather than focusing only on the unit price.

Frequently Asked Questions About Custom Corrugated Mailer Boxes
What are custom corrugated mailer boxes?
They are boxes made from corrugated board, typically used for ecommerce shipping, branded packaging, subscription products and promotional gift sets.
Are corrugated mailer boxes the same as airplane boxes?
In China, many self-locking corrugated mailer boxes are commonly called “airplane boxes” because of their unfolded shape. International buyers generally use terms such as mailer boxes, corrugated mailers or roll-end tuck-front boxes.
Can custom corrugated mailer boxes be printed inside and outside?
Yes. Selected constructions support printing on both the exterior and interior surfaces, depending on the printing process and material.
Can corrugated mailer boxes be shipped flat?
Many empty mailer box designs can be supplied flat and assembled when needed. For freight quotes, distinguish export cartons of flat empty mailers from individual filled parcels: they have different dimensions, weights and packing arrangements. Confirm the supply format for the chosen structure.
What is the difference between E flute and B flute?
E flute generally has a thinner profile, while B flute is thicker. The most suitable option depends on the box size, contents, printing requirements and performance needs.

Yes. Depending on the product, inserts may include corrugated dividers, folded paperboard holders, molded pulp components or other protective materials.
Are corrugated mailer boxes suitable for fragile products?
They may be suitable when combined with appropriate cushioning, inserts and validated packaging performance. Corrugated board alone does not guarantee protection for fragile items.
Can you produce self-sealing mailer boxes?
Self-sealing options may be available, including selected adhesive-strip and tear-strip designs. Availability depends on the structure and manufacturer.
What is the minimum order quantity?
MOQ depends on the box dimensions, corrugated board, printing requirements, structure and supplier. Please share your estimated quantity for a project-specific quotation.
