Corrugated Shipping Boxes

Custom Corrugated Shipping Boxes for Businesses and E-Commerce

Shipping packaging has to do more than hold a product. It needs to accommodate the packed item, suit the way it will be handled, and provide a practical format for storage and transportation. Corrugated shipping boxes are widely used for these purposes because their layered paperboard construction can be specified in different strengths, thicknesses, and box styles.

At Bluebird Packaging, businesses can explore custom corrugated shipping boxes developed around their product dimensions, packaging requirements, and brand presentation. From everyday e-commerce cartons to larger shipping cases, the box design can be planned according to the product’s weight, size, packing arrangement, and intended distribution route.

You can customize the box dimensions, board construction, printing, and finishing details to create packaging that fits your operational needs. Whether you are shipping individual orders, grouping multiple products, or preparing goods for commercial distribution, selecting the right corrugated structure is an important part of the packaging process.

What Are Corrugated Shipping Boxes?

Corrugated shipping boxes are containers made from corrugated fiberboard. This material generally consists of flat paper liners with a wavy paper layer, known as fluting, between them. The fluted layer creates a structured board that can provide stiffness and cushioning characteristics while keeping the packaging relatively lightweight.

The construction can vary according to the number of layers, flute profile, paper specifications, and intended use. These factors influence the box’s compression resistance, stacking performance, print surface, and overall suitability for a particular shipment.

Corrugated cartons are used across many industries, including:

• E-commerce and online retail.
• Apparel and fashion.
• Consumer electronics and accessories.
• Home and kitchen products.
• Books and printed materials.
• Beauty and personal care.
• Food-related products, subject to appropriate material and regulatory requirements.
• Industrial components and commercial supplies.

A suitable box should be selected according to the actual packed product and shipping conditions. No single corrugated construction is ideal for every item or delivery route.

Why Businesses Choose Corrugated Shipping Boxes

Corrugated packaging offers several practical design advantages for businesses that ship products regularly. Its versatility allows box specifications to be adjusted for different products, order sizes, and distribution needs.

1. Multiple Board Strength Options

Corrugated board can be specified in different constructions and grades. This allows businesses to consider lighter board for suitable products or stronger constructions for heavier loads and demanding handling conditions.

The appropriate specification should be based on product weight, dimensions, stacking requirements, and the shipping environment.

2. Customizable Dimensions

Standard box sizes do not always match a product’s actual dimensions. Custom corrugated shipping boxes can be designed around the length, width, and height of the packed item.

A properly planned size can reduce unnecessary empty space and help organize the product with suitable cushioning or inserts.

3. Flexible Box Structures

Corrugated board can be converted into different box styles, including regular slotted cartons, full-overlap containers, die-cut boxes, and other custom structures.

The best style depends on how the product will be packed, closed, stored, and shipped.

4. Printing and Branding Opportunities

Corrugated shipping cartons can include printed logos, brand names, handling information, and other approved artwork. Printing can be planned according to the board surface, artwork complexity, and production method.

This allows shipping packaging to support brand recognition as well as its practical role.

5. Flat Storage and Assembly

Many corrugated box styles can be supplied flat before assembly. This can make storage and handling more convenient compared with storing fully assembled empty cartons.

The exact packing and supply format depends on the selected box construction and production arrangement.

6. Paper-Based Packaging Options

Corrugated fiberboard is paper-based and may be suitable for established paper recycling streams where local collection and recycling facilities accept the material. Coatings, laminations, tapes, labels, contamination, and local recycling rules can affect how a finished package is handled.

Environmental claims should be based on the actual material specification and the recycling facilities available in the intended market.

Types of Corrugated Shipping Boxes

Different corrugated box constructions serve different packaging requirements. Selecting the right type involves evaluating product weight, box dimensions, stacking conditions, and the level of protection required.

1. Single-Wall Corrugated Shipping Boxes

Single-wall corrugated boxes generally consist of one fluted medium between two flat liner sheets. They are commonly considered for everyday shipping applications involving suitable lightweight and medium-weight products.

Businesses may use single-wall cartons for apparel, accessories, household items, packaged retail products, and many e-commerce orders.

The final board grade should still be selected according to the packed weight and shipping conditions. A single-wall box is not automatically suitable for every lightweight product, particularly when the contents are fragile or the parcel will experience demanding handling.

2. Double-Wall Corrugated Shipping Boxes

Double-wall corrugated boxes contain two fluted layers separated and covered by liner sheets. This construction provides a different strength profile from single-wall board and may be considered for heavier products, larger cartons, or shipments that involve more demanding stacking conditions.

Explore our double-wall shipping boxes for a related packaging option.

The right double-wall specification depends on the complete shipment, including packed weight, box dimensions, stacking arrangement, and distribution conditions.

3. Heavy-Duty Corrugated Shipping Boxes

Heavy-duty corrugated shipping boxes are developed for applications that require a stronger board specification or a more substantial box construction.

They may be considered for dense products, larger components, commercial supplies, or shipments where stacking and handling conditions require additional attention.

Explore our heavy-duty shipping boxes when comparing packaging options for demanding applications.

The term heavy-duty should always be supported by an actual board specification and suitable performance requirements rather than used as an unsupported guarantee.

4. Custom Printed Corrugated Shipping Boxes

Custom printed corrugated boxes combine shipping functionality with brand presentation. Businesses can add logos, brand colors, product identification, handling instructions, and other approved artwork.

Printing can be planned for selected panels or surfaces depending on the box style and available production methods.

5. Kraft Corrugated Shipping Boxes

Kraft corrugated boxes use kraft-style liner surfaces and are often selected for their familiar natural paper appearance. They can be considered for plain shipping cartons or branded packaging with suitable printing.

Their board construction and strength still need to be selected according to the product and shipping conditions.

6. Full-Overlap Corrugated Boxes

Full-overlap containers use flaps that extend across more of the box opening than standard regular slotted cartons. When closed, the overlapping flaps create additional layers across the closure area.

This style may be considered when the packaging design calls for greater coverage across the top and bottom panels. The complete structure should be evaluated for the intended load and handling conditions.

7. Regular Slotted Containers

A regular slotted container, commonly called an RSC, is a widely used corrugated box style. Its inner and outer flaps are arranged so that the outer flaps meet near the center when the box is closed.

RSC cartons are used in many shipping applications because their straightforward structure can be adapted to a wide range of dimensions.

8. Die-Cut Corrugated Boxes

Die-cut boxes are made using a cutting pattern designed for a specific structure. They may include tuck closures, integrated locking features, shaped panels, or other design details.

A custom die-cut format can be considered when a standard slotted carton does not match the product’s packaging or presentation requirements.

Understanding Corrugated Board Construction

When ordering custom corrugated shipping boxes, it is useful to understand the basic construction of the board. The combination of liner sheets and fluting affects the box’s physical characteristics.

What Is a Corrugated Flute?

The flute is the wavy paper layer inside corrugated board. It is positioned between liner sheets and contributes to the board’s structure.

Flutes are available in different profiles. Their height, spacing, and configuration influence board thickness, cushioning characteristics, stiffness, and printing considerations.

Common Flute Types

The appropriate flute depends on the box design, product weight, desired thickness, and packaging application.

A-flute: A relatively thick flute profile that may be considered where cushioning and board thickness are important.

B-flute: A thinner profile than A-flute, often used for shipping cartons and packaging applications where a more compact board is preferred.

C-flute: A commonly used general-purpose flute profile that balances several structural characteristics.

E-flute: A thinner profile that can be considered for smaller cartons and packaging designs where a relatively smooth printable surface is useful.

F-flute: A fine flute profile used in selected packaging applications where a thinner board and detailed printed appearance are required.

These are general descriptions, not a substitute for a specific board specification. The right flute should be chosen with the box manufacturer according to the product and intended use.

Single-Wall, Double-Wall, and Triple-Wall Construction

The number of fluted layers is another important consideration.

More layers do not automatically make a box suitable for every shipment. Box dimensions, paper grades, flute combinations, closure design, and packing conditions all influence performance.

Choosing the Right Corrugated Shipping Box Strength

Box strength should be selected according to the product and the environment in which the package will be handled. Choosing a specification based only on the product’s weight may overlook important factors such as stacking, vibration, moisture exposure, and transportation distance.

Edge Crush Test (ECT)

Edge Crush Test, commonly abbreviated as ECT, measures the resistance of corrugated board to compression applied to its edge. It is often used as one indicator when assessing a board’s stacking-related characteristics.

A higher ECT value generally indicates greater edge-crush resistance under the test conditions. However, ECT alone does not describe every aspect of a finished box’s performance.

Burst Strength

Burst strength measures the pressure required to rupture a sample of corrugated board. It is another way of describing a board property, but it is not directly interchangeable with ECT.

The correct specification depends on the application and the relevant testing or shipping requirements.

Factors That Affect Box Strength

Consider the following factors when selecting a corrugated shipping box:

• Total packed weight.
• Product shape and weight distribution.
• Box length, width, and height.
• Number of boxes stacked together.
• Storage duration and conditions.
• Shipping distance and transportation method.
• Handling and sorting conditions.
• Internal cushioning and product arrangement.
• Moisture exposure and environmental conditions.

A packaging supplier can help assess the board specification, but representative samples and appropriate testing are important when shipment performance is critical.

Custom Corrugated Shipping Box Sizes

Custom sizing helps businesses develop cartons around the actual product instead of relying on an unsuitable standard dimension.

A box that is too tight may not accommodate the product or cushioning. A box that is unnecessarily large can increase material use and may create additional empty space that needs to be filled.

How to Measure a Corrugated Shipping Box

For most box specifications, dimensions are provided as internal length × width × height. Always confirm whether the supplier is requesting internal or external measurements.

Length: Measure the longer internal side of the assembled box.

Width: Measure the shorter internal side of the base.

Height: Measure from the inside bottom panel to the inside top closure.

Also consider the product’s dimensions, protective material, inserts, and the space needed to place the product inside the carton.

For a detailed measurement reference, read our guide on how to measure a box correctly.

Internal vs. External Dimensions

Internal dimensions describe the usable space inside the carton. External dimensions include the thickness of the corrugated board and are relevant to the package’s outside measurements.

This difference matters when products need a precise fit or when shipping systems use the outside dimensions to calculate parcel size.

Right-Sizing Your Shipping Cartons

A well-sized carton should accommodate the product and the required cushioning without leaving unnecessary empty space.

When selecting dimensions:

1. Measure the product at its widest and longest points.
2. Identify whether the product needs wrapping or cushioning.
3. Account for inserts, dividers, or multiple items.
4. Consider how the carton will be closed.
5. Confirm the internal dimensions with a sample.
6. Check the external dimensions for storage and shipping calculations.

Corrugated Shipping Boxes for Different Industries

Corrugated packaging is used across a wide range of business applications. The box structure and material specification should reflect the product rather than relying on a one-size-fits-all design.

E-Commerce and Online Retail

Online retailers use corrugated shipping boxes to pack individual orders, product bundles, and subscription shipments.

Custom sizes can help accommodate products and packing materials. Printed logos and brand elements can also be included where the selected board and printing process allow.

For e-commerce shipments, consider the parcel’s dimensions, packed weight, internal movement, and handling throughout the delivery route.

Apparel and Fashion

Clothing brands may use corrugated cartons for shipping garments, footwear, accessories, and multi-item orders.

The carton size should reflect the number of products being packed and the way they are folded or arranged. Dividers or inner packaging may be considered when different items need to be separated.

Electronics and Accessories

Electronics and accessories can vary significantly in size, weight, and fragility. Their shipping cartons may require fitted inserts, cushioning materials, or separate compartments.

The outer corrugated box should be designed as part of the complete packaging system. Fragile or sensitive products may require testing to evaluate whether the selected structure and internal protection are suitable.

Books and Printed Materials

Books, catalogs, and printed materials are often packed in cartons selected according to their dimensions, weight, and quantity.

A suitable carton should accommodate the stack without excessive movement. The board specification should account for the combined packed weight and stacking conditions.

Home and Kitchen Products

Home and kitchen products include a wide range of shapes and materials. Some items can be packed in standard cartons, while others may need internal dividers, shaped inserts, or additional cushioning.

The packaging design should consider the product’s weight distribution and the possibility of movement inside the box.

Industrial and Commercial Products

Industrial components and commercial supplies may require larger cartons or stronger corrugated constructions. Their specifications should be based on product density, load arrangement, handling equipment, and distribution conditions.

For heavier products, a supplier should review the complete packaging requirements before recommending a board grade or box structure.

Custom Printed Corrugated Shipping Boxes

Shipping cartons can also contribute to the way customers recognize and experience a brand. Custom printing allows businesses to use selected box panels for identification, branding, and approved communication.

Logo and Brand Printing

A business logo can be added to the outside of the carton to identify the sender or create a consistent branded appearance. Brand colors, typography, and selected graphics can also be incorporated according to the print method and board surface.

Product and Handling Information

Depending on the shipment, printed information may include:

• Product or order identification.
• Company name or logo.
• Delivery or handling instructions.
• Orientation symbols.
• Fragile or other handling indicators, where appropriate.
• Product codes or other approved markings.

Handling symbols should be used accurately and should not replace suitable packaging design.

Exterior and Interior Printing

Exterior printing is commonly considered for shipping cartons. Interior printing may also be possible depending on the box construction and production method.

The available print coverage, number of colors, and artwork detail should be confirmed during specification.

Preparing Artwork for Printing

Before sending artwork, prepare:

• A high-resolution logo or vector artwork.
• Brand color references.
• Final text and product information.
• The preferred print areas.
• Any required handling symbols.
• The approved box dimensions and dieline, if available.

Always review a proof or sample before approving a production run. This helps identify layout, spelling, sizing, and print-placement issues.

Corrugated Shipping Boxes with Inserts and Dividers

Some products need more than an outer carton. Inserts and dividers can help organize multiple items or position individual products within the box.

Corrugated Inserts

Corrugated inserts can be designed to fit around products or create internal support areas. They may be used for selected product shapes and packaging configurations.

Dividers for Multiple Products

Dividers can separate items within a carton. They may be considered for products packed in rows, groups, or multiple compartments.

Explore our packaging dividers information for more details about internal product separation.

Choosing an Insert Design

When planning an insert, consider:

• Product dimensions and shape.
• Number of items per carton.
• Weight of each item.
• Required separation between products.
• Ease of packing and removal.
• Compatibility with the outer box.
• The complete packed arrangement.

Inserts should be designed around the actual products and checked with a physical sample when fit is important.

Corrugated Shipping Boxes for Storage and Transportation

Shipping cartons may pass through several stages before reaching their destination. They can be packed, closed, stacked, moved through a warehouse, loaded into a vehicle, and handled during delivery.

The packaging design should take these stages into account.

Warehouse Storage

For warehouse storage, consider the available space, stacking arrangement, carton dimensions, and expected storage duration.

Boxes should be stacked according to their specifications and the load they are designed to carry. Excessive stacking or unsuitable storage conditions can affect carton performance.

Parcel Shipping

Parcel shipments can involve sorting equipment, manual handling, vehicle movement, and repeated transfers.

The box should be appropriately sized and closed, with internal cushioning selected according to the product’s fragility and movement potential.

Palletized Shipments

When multiple cartons are stacked on a pallet, the lower boxes may experience compression from the load above them.

The box specification should account for pallet arrangement, stacking height, load distribution, and storage conditions.

Long-Distance and Export Shipping

Long-distance shipments may involve multiple handling stages and changes in transportation method. Export packaging should be assessed according to the destination, route, shipment conditions, and applicable buyer or regulatory requirements.

A standard corrugated carton should not be assumed to provide protection against every environmental or transportation condition.

For more guidance, explore our packaging for shipping guide.

How to Pack Corrugated Shipping Boxes Correctly

The box itself is only one part of the packaging system. Packing methods, cushioning, closure, and product placement also influence the suitability of a shipment.

Prepare the Carton

Assemble the carton according to its design. Close and seal the bottom flaps with a suitable packaging tape or closure method for the intended load.

Position the Product

Place the product in the carton with enough room for any required cushioning. Avoid placing heavy items in a way that concentrates excessive pressure on a small area of the box.

Add Suitable Cushioning

Use suitable cushioning or internal packaging when the product needs separation from the box walls or other items. The choice depends on the product’s fragility, weight, and shipping conditions.

Prevent Unwanted Movement

If the product can shift during transportation, consider inserts, dividers, or additional packing material to keep the arrangement stable.

Close and Seal the Carton

Close the flaps and apply a suitable sealing method. The tape or closure should be appropriate for the carton size, weight, and handling requirements.

Label the Shipment

Apply a clear shipping label with the correct delivery information. Include any applicable handling information required for the shipment.

Testing and Quality Considerations for Corrugated Shipping Boxes

Packaging testing can help businesses evaluate whether a box specification is suitable for its intended application. The appropriate tests depend on the product, packaging design, distribution conditions, and customer requirements.

Possible evaluation areas include:

• Board thickness and construction.
• Edge crush performance.
• Burst strength, where specified.
• Box compression under stacking conditions.
• Drop or impact testing.
• Vibration testing.
• Moisture-related considerations.
• Closure and sealing performance.
• Fit of inserts and internal components.

Not every shipment requires every test. Testing should be selected according to the risks and requirements of the particular product and distribution route.

For further information, read our guide to packaging testing and evaluation.

How to Select a Corrugated Shipping Box Supplier

Choosing a supplier involves more than comparing the price of a carton. The supplier should be able to understand your packaging requirements and help define a suitable specification.

Consider the following points:

Custom Manufacturing Capabilities

Check whether the supplier can produce your required dimensions, box styles, and board constructions.

Material and Board Specifications

Ask for clear details about the corrugated construction, flute combination, liner specifications, and relevant strength ratings.
