Single wall boxes are one of the most common and versatile packaging options available for businesses and households. Designed using a single layer of corrugated cardboard fluting between two linerboards, these boxes offer reliable protection for light to medium-duty tasks such as storage, ecommerce shipping, and postal deliveries.
Choosing the right cardboard box type matters significantly in logistics and cost management. While robust packaging like double wall boxes or pallet boxes are ideal for heavier or fragile goods, single wall cardboard boxes provide a cost-effective, eco-friendly alternative for lighter items.
This guide explores everything from how single wall boxes are made to their key benefits, limitations, and where to buy them, helping you make informed packaging choices.
What Are Single Wall Boxes?
A single wall box is a type of cardboard packaging that consists of one layer of corrugated fluting sandwiched between two flat linerboards. This structure provides cushioning and rigidity while keeping the packaging lightweight and easy to handle.
Corrugated fluting refers to the wavy, inner paper layer that gives these boxes their structural strength. The material used is often high-quality corrugated cardboard, making the box flexible for various applications.
They're typically used for postal packaging, ecommerce packaging, and storing non-fragile items. Don't confuse them with single layer cardboard, which lacks fluting and offers minimal strength. The fluted structure sets single wall boxes apart by enhancing durability while keeping materials minimal.
How Are Single Wall Cardboard Boxes Made?
The process begins with crafting corrugated cardboard by bonding fluted paper to two linerboards. These materials are derived primarily from recycled paper, contributing to their eco-friendly appeal. Once the corrugated board is created, it's cut and folded into specific box sizes using die-cutting or slotting machinery.
The components include:
-
Outer wall: smooth paper that gives the box shape and holds graphics or labels.
-
Fluted paper: the central cushioning layer.
-
Inner wall: another linerboard that completes the sandwich structure.
Other related materials like paper bags, board backed envelopes, and cardboard wraps often accompany single wall packaging for added flexibility. Customisation options like bespoke packaging are common, especially in retail and ecommerce industries.
Single Wall vs Double Wall Boxes: Key Differences
Understanding the difference between single wall and double wall boxes is essential when choosing packaging.
Double wall boxes include two layers of corrugated fluting, providing extra strength, resistance to compression, and better durability. They are commonly used for shipping heavy items, acting as removal boxes or moving boxes, and for warehouse storage.
In contrast, single wall cardboard boxes are lighter, more affordable, and suitable for lighter items. They also save space during storage and handling, which makes them preferable for storage boxes and general-use shipping boxes.
While double wall options outperform in strength, single wall varieties are ideal when cost-efficiency and weight reduction are priorities.
Common Sizes and Variants
Single wall boxes come in a range of sizes designed to accommodate different packaging needs. Their structural simplicity makes them highly adaptable.
Small Cube Single Wall Boxes
These compact boxes are perfect for shipping books, cosmetics, jewellery, or small electronics. Their cube shape helps protect items from movement during transit, especially when combined with materials like bubble wrap or padded envelopes.
Large Single Wall Boxes
Larger boxes are commonly used for packaging clothing, lightweight bulk storage, or items like linens and soft furnishings. They offer volume without adding unnecessary weight, which helps reduce postal costs and improves handling.
For businesses that require non-standard sizes, bespoke packaging options allow custom cuts, prints, and designs to suit branding or specific products.
Top Uses of Single Wall Boxes in Packaging
Due to their lightweight nature and cost-efficiency, single wall cardboard boxes are widely used across multiple sectors.
-
In ecommerce packaging, they serve as postal boxes and white postal boxes, ideal for mailing consumer products.
-
Retailers use them for product presentation and protection during delivery.
-
In offices and warehouses, they function as reliable storage boxes and help in inventory organisation.
-
They're also common in book wraps, protecting literature during shipping and minimising damage.
Such versatility makes them a staple in both B2B and B2C packaging environments.
Single Wall Boxes for Shipping and Ecommerce
For businesses in the ecommerce sector, single wall boxes are invaluable due to their lightweight and flexible nature.
They help reduce shipping costs without compromising protection when paired with packaging aids like plastic carrier bags, bubble wrap, or document enclosed wallets. For returns, combining these boxes with masking tape or packing tape ensures secure resealing.
Moreover, they integrate seamlessly into fulfilment workflows by being compatible with automated taping, labelling, and stacking processes—key for high-volume operations.
Benefits of Using Single Wall Cartons
Single wall cartons offer several advantages, especially for businesses aiming to optimise packaging expenses and eco-footprints.
They're:
-
Cost-effective: Lower production and shipping costs due to lighter material.
-
Environmentally friendly: Often made from recycled paper and fully recyclable after use.
-
Space-efficient: Easy to flatten, store, and assemble on demand.
-
User-friendly: Easily sealed using packaging tape, masking tape, or packing tape.
-
Customisable: Can be printed, labelled, or branded according to product or company needs.
Their flexibility makes them a preferred option for lightweight logistics.
Limitations of Single Walled Cardboard Boxes
Despite their benefits, single walled boxes aren't ideal for every situation.
They are not suitable for:
-
Heavy or fragile items, which risk damage without sufficient strength.
-
Long-term storage under weight, due to lower stacking durability.
-
Repeated use, as they wear out faster than double wall or pallet boxes.
To mitigate these drawbacks, users often combine them with corrugated paper rolls, grey mailing bags, or even furniture covers for added support.
Additional Packaging Products to Use With Single Wall Boxes
When using single wall boxes, it's essential to pair them with complementary packaging products for optimal results.
Some widely used additions include:
-
Grey mailing bags for weather protection
-
Clear pallet wrap and black pallet wrap for securing grouped shipments
-
Furniture covers during moves or warehousing
-
Corrugated paper rolls for added cushioning inside the box
These accessories help maintain product safety and streamline logistics.
How to Choose the Right Single Wall Box
Choosing the correct single wall box involves considering the item's size, weight, and fragility. For heavier items or longer distances, it's wise to upgrade to double wall alternatives or reinforce with additional layers.
Also, assess your storage and shipping conditions. High humidity, rough handling, or stacking needs can reduce box integrity.
Match the box with protective packaging like padded envelopes, bubble wrap, or board backed envelopes to enhance protection during transit.
Sustainable Packaging: Are Single Wall Boxes Eco-Friendly?
Yes, single wall boxes are among the more eco-friendly options in packaging. Made primarily from biodegradable, recycled, and recyclable paper materials, they significantly reduce packaging waste.
Compared to plastic packaging, they offer a cleaner end-of-life outcome. Many businesses now prefer cardboard for this reason, especially in light of new sustainability regulations in the UK and EU.
Their use supports eco-initiatives while meeting customer demand for green shipping.
Where to Buy Single Wall Boxes
You can purchase single wall cardboard boxes from various online retailers, local suppliers, or wholesale packaging providers.
For larger volumes, sourcing from custom packaging manufacturers allows better control over design, size, and branding. Look for vendors offering certifications like FSC or ISO to ensure quality and sustainability standards.
When choosing a supplier, check reviews, delivery speeds, and whether they offer related materials like postal boxes, bubble wrap, or packaging tape.
