Single Wall Boxes/Cartons
Overview
The 455 x 305 x 250 mm (approx. 18 x 12 x 10 in) single wall carton is a versatile corrugated cardboard box designed for everyday packing, storage and distribution. As a single wall (S/W) case, it offers a practical balance of strength and efficiency for a wide range of general-purpose applications—ideal when you need a dependable shipping carton without the extra material of a double wall alternative.
Whether you’re dispatching products to customers, organising stock in a storeroom, or preparing items for courier collection, this carton size is a popular choice because it suits many common product shapes and allows straightforward stacking on shelves, pallets and in vehicles. It’s also a convenient option for businesses that want a consistent, repeatable packing process: the footprint and height work well with standard void fill, tape and labels, helping teams pack quickly and neatly.

455 x 305 x 250 Single Wall Carton — Full Product Guide
Choosing the right carton is about more than just dimensions. The best results come from matching the box style and board type to your product weight, fragility, and distribution method. Use the guide below to help you decide if this single wall carton is the right fit for your packing operation and how to get the best performance from it.
How It Works
This carton is supplied flat-packed for efficient storage. To use it, fold along the pre-scored creases, form the box shape, and seal the base with packing tape. Place your product inside, add protective packaging as needed, then close and seal the top flaps. For best results, aim for a snug fit: minimise empty space to reduce movement in transit, and use void fill to immobilise the contents.
Materials and Construction
Single wall cartons are made from corrugated board consisting of one fluted (wavy) layer bonded between two liner sheets. This structure provides rigidity and cushioning while keeping the carton lightweight and economical. Single wall board is commonly selected for general-purpose shipping where loads are moderate and handling conditions are typical of parcel networks and standard warehouse distribution.
Why corrugated matters:
The fluted core helps absorb knocks and vibration, while the liners provide a smooth surface for labels and tape adhesion. When packed correctly, corrugated cartons can offer excellent performance for everyday shipping and storage tasks.
Floor Type Compatibility
In a warehouse or packing environment, cartons are often moved across different floor types and handling systems. This carton format is suitable for use with:
- Standard shelving and racking
- Palletised storage and distribution (when stacked and wrapped appropriately)
- Conveyor and packing bench workflows (where cartons are erected, filled and sealed)
If cartons will be dragged across rough floors or handled in high-friction environments, consider using pallets, totes, or slip sheets to reduce abrasion and maintain carton integrity.
Health and Safety
Safe packing practices help protect both staff and goods:
- Manual handling: Avoid overfilling. Keep packed cartons within safe lifting limits for your workplace and use team lifts or handling aids where required.
- Cutting tools: Use safety knives when opening cartons and keep blades away from the body.
- Stacking: Stack on a stable, level surface. Heavier cartons should be placed at the bottom of a stack to reduce the risk of collapse.
- Sealing: Apply tape evenly and firmly to prevent flaps lifting during transit.
Ideal Applications and Use Cases
This single wall carton is a strong candidate when you need a dependable, general-purpose shipping box. It is commonly used for:
- Mixed product orders: A practical size for packing multiple smaller items together with void fill.
- Stock replenishment: Moving goods between sites, departments or storage locations.
- Spare parts and components: Packing items that benefit from a rigid outer case and internal cushioning.
- Subscription and repeat shipments: Standardising packaging for consistent presentation and packing speed.
Maintenance, Cleaning and Care
Corrugated cartons are designed primarily for single-trip shipping, but they can sometimes be reused for storage if they remain clean and structurally sound. To keep cartons in good condition:
- Store flat cartons in a dry area away from moisture and direct water exposure.
- Avoid compressing bundles under heavy loads, which can weaken creases and edges.
- Keep cartons away from oils, chemicals and contaminants that may affect board strength or label adhesion.
- If reusing, inspect corners, flaps and base seams for crushing or tears before packing.
Case Study (Example Packing Workflow)
Scenario: A small fulfilment team ships daily orders containing multiple boxed items and accessories. They need a carton that is quick to assemble, stacks neatly, and provides enough space for protective packaging.
Approach: The team erects the carton, tapes the base, places a cushioning layer, then packs items with void fill to prevent movement. A final top layer is added before sealing. Labels are applied to the smooth outer liner for clear scanning.
Result: A consistent packing process that improves speed at the bench and helps reduce in-transit movement by using the carton size efficiently.
