Single wall boxes are a trusted packaging option for both commercial and domestic use. They are made from a single layer of corrugated cardboard, offering a good balance between strength and affordability. Ideal for lightweight to medium-weight items, these boxes are widely used in ecommerce, retail, and removals.

This article explores the structure, strength, sustainability, and best use cases of single wall boxes. We also compare them with double wall boxes and bespoke solutions, guiding you in choosing the right box for your needs—whether you're packing, posting, or storing.

What Are Single Wall Boxes?

Single wall boxes consist of a single layer of corrugated fluting enclosed between two linerboards. They are used in shipping, storage, and ecommerce packaging due to their cost-efficiency and ease of handling.

They differ from double wall boxes, which have two corrugated layers for added durability. For most lightweight goods, single wall packaging provides reliable protection without the added material cost.

Understanding the Structure of a Single-Wall Cardboard Box

The term "single wall" refers to the single corrugated layer inside the cardboard sheet. This layer provides structure and shock absorption.

Corrugated fluting: This is the wavy middle layer that adds cushioning and rigidity.

Linerboards: These flat outer sheets protect the fluting and give the box its finished appearance.

Fluting types:

B-flute: Approximately 3.2 mm thick; suitable for moderate protection and strength.

E-flute: Around 1.6 mm thick; commonly used for retail and display packaging.

Compared to a single wall carton, double wall boxes are more resistant to crushing but are also heavier and costlier.

Common Sizes and Types Available

Single wall boxes are manufactured in various dimensions for different use cases.

Small Cube Single Wall Boxes: Ideal for shipping books, cosmetics, and small tech items. These are compact and suitable for postal boxes or ecommerce packaging.

Large Single Wall Boxes: Suitable for bulkier yet lightweight items, such as clothing or plastic containers. Often used in home moves or stock storage.

Single wall carton types: Available in flat-pack formats for easy storage, and custom-sized options for bespoke applications.

Key Features and Specifications

These boxes offer dependable performance when matched with the right contents and transport conditions.

Single Wall Boxes Thickness and Strength

Box strength is largely influenced by thickness, which comes from the fluting profile.

Typical thickness: Ranges from 1.5 mm (E-flute) to 4 mm (B-flute).

Impact on strength: Thicker fluting increases compression strength, suitable for stacking and moderate shipping demands.

Material used: Made from corrugated cardboard, providing both lightness and structural support for general use.

Weight Capacity of Single Walled Cardboard Boxes

These boxes are best suited for medium and low-weight items.

Weight range: Can typically support 7–15 kg, depending on box size and fluting.

Limitations: Not recommended for fragile or heavy goods that need extra support.

Precaution: Use packing tape, black pallet wrap, or switch to double wall boxes for added protection in demanding conditions.

Sustainability and Materials

Sustainability is a key benefit of single wall packaging, especially for eco-conscious businesses.

Recyclability: 100% recyclable and made from renewable materials.

Environmental comparison:

Outperforms plastic carrier bags in terms of environmental impact.

Offers greater protection than paper bags while maintaining biodegradability.

Eco-aligned strategy: Ideal for companies committed to eco-friendly packaging practices and circular economy values.

When to Use Single Wall Boxes

Understanding when to choose single wall packaging ensures both efficiency and cost control.

Ideal Applications

These boxes are effective for most general-purpose packaging needs.

Postal packaging: Lightweight items for courier or post, such as documents and electronics.

Retail & ecommerce: Used in shelf-ready packaging, white postal boxes, and book wraps.

Home and office use: Suitable for moving boxes, storage boxes, and light removal boxes.

When to Choose Double Wall or Bespoke Packaging Instead

Heavier or fragile goods require more durable packaging.

Double wall boxes: Preferred for long-distance or heavy item shipping due to their dual fluting layer.

Bespoke packaging: Recommended when product dimensions are irregular or when branding is important.

Complementary items: Add pallet wrap, furniture covers, or pallet boxes for protection during transit.

Enhancing Your Packaging with Protective Extras

Even the right box needs additional protection for certain items.

How to Pack Items in Single Wall Boxes Securely

Secure packing prevents damage and maximises space efficiency.

Internal cushioning: Use bubble wrap, corrugated paper rolls, or padded envelopes to protect contents.

Sealing: Apply strong packing tape or masking tape to seal edges and flaps tightly.

Void fill: Fill empty space to prevent item movement during transit.

Labelling and Delivery Readiness

Accurate and secure labelling helps ensure successful deliveries.

Document holders: Attach a board backed envelope or document enclosed wallets for invoices and shipping labels.

Ecommerce system integration: Print labels directly from your fulfilment software to speed up operations.

External add-ons: Pair boxes with grey mailing bags or postal packaging for multi-layered protection.
