Double Wall Cartons 450x450x516mm

Our Double Wall Cartons 450x450x516mm offer a spacious square-base format for packing, dispatch and indoor storage. Their taller proportions accommodate suitable bulky goods or carefully arranged groups of smaller products.

Double-wall board incorporates two corrugated layers between liner sheets. However, the performance of the finished carton also depends on its materials, contents, closure and handling conditions.

Choosing a box that matches the dimensions of your protected goods can help avoid unnecessary empty space. Consequently, you may need less void fill than you would with an oversized carton.

The outer box forms one part of the complete packing system. Suitable wrapping, cushioning and separation remain important, particularly when several products share the same package.

We can discuss carton sizes and complementary materials with you. Before regular use, prepare a trial pack using your actual contents and intended closure method.

Double Wall Cartons 450x450x516mm Dimensions and Specifications

• Product type: Corrugated cardboard carton.
• Construction: Double wall.
• Board structure: Two corrugated layers between liner sheets.
• Metric dimensions: 450mm x 450mm x 516mm.
• Approximate imperial dimensions: 17.72 x 17.72 x 20.31 inches.
• Dimension order: Width x depth x height.
• Base shape: Square.
• Applications: Packing, dispatch and indoor storage of suitable goods.

The imperial measurements are approximate conversions of the supplied metric dimensions. Therefore, use the metric size when comparing the carton with your product measurements.

Allow room for protection beneath, above and around the contents. In addition, include any dividers or retail packaging that will remain inside the box.

For close-fitting products, check the usable internal dimensions with us before ordering. The nominal carton size should not replace a practical fit test.

Consider the complete packed weight alongside the measurements. A larger carton provides more space, but that does not mean you should fill it with dense or heavy contents.

Understanding Double Wall Cartons 450x450x516mm Measurements

Measure your product after adding the protective wrapping you intend to use. This gives you a more reliable starting point than measuring the bare item alone.

First, check the widest and deepest points of the protected goods. Then measure their full height, including cushioning beneath or above them.

Bulky products may have uneven shapes. For example, handles, projecting corners and outer retail packaging can increase the space they require.

If several items will share one carton, arrange them as you intend to pack them. Likewise, include separators where products could knock or rub against one another.

The carton should close naturally without pressure from the contents. At the same time, avoid leaving large gaps that permit unwanted movement.

A trial pack also helps you check access. You should be able to load and remove the goods without forcing them against the cardboard.

Choosing Double Wall Cartons 450x450x516mm

Double Wall Cartons 450x450x516mm may suit applications where you need a larger double-wall outer package with a square base. Start by checking the protected dimensions and intended arrangement.

Consider the weight, shape and fragility of each product. In addition, think about how the completed carton will be carried, stored and transported.

Bulky textiles may occupy much of the space without creating the same packed weight as dense components. Delicate homeware, by contrast, may require substantial cushioning and separation.

Do not assume that double-wall construction removes the need for protective materials. Products can still move inside a securely closed box unless the packing method keeps them stable.

Choose a smaller carton when the contents do not need this much space. Similarly, divide an order between suitable boxes if one large package would become difficult to handle.

Before regular use, test a representative pack. This allows you to assess the carton, contents, protection and closure together.

How to Assemble Double Wall Cartons 450x450x516mm

Prepare a clean, dry packing area with enough room to handle the carton. Keep suitable tape, cushioning and labels within easy reach.

Follow the carton’s folds and creases to form its intended shape. Next, secure the base using a closure method appropriate to the design and contents.

Check that the assembled carton sits squarely. Its base should remain secure when you add the intended products and packing materials.

If you use adhesive tape, apply it to clean, dry cardboard and press it down firmly. In addition, make sure it bridges the relevant seams securely.

Place any base cushioning inside before loading the goods. Then add the remaining protection without pushing the side panels out of shape.

Close the top only when the contents fit comfortably. Finally, inspect the base, top and closure areas before moving the finished package.

Packing with Double Wall Cartons 450x450x516mm

A suitable packing method helps keep products stable inside their outer carton. Therefore, choose protection according to the contents rather than using one approach for every order.

Wrap delicate surfaces individually where necessary. In addition, separate products that could scratch, knock or press against one another.

Provide suitable cushioning beneath, above and around fragile items. Pay particular attention to exposed corners, handles and protruding parts.

Use appropriate void fill to occupy unwanted gaps. However, avoid forcing excessive material into the carton, as this can distort the panels or prevent proper closure.

If you arrange goods in layers, use suitable separation between them. Do not allow heavier products to press directly onto fragile contents below.

Keep the completed package manageable rather than trying to use every available space. For mixed orders, several smaller cartons may offer a more practical packing arrangement.

Check for unwanted movement using a method appropriate to the goods. Once you are satisfied, seal the carton securely and apply a clear delivery label.

Double Wall Cartons 450x450x516mm for Business, Storage and Removals

Double Wall Cartons 450x450x516mm can help organise suitably sized goods within a business packing routine. For example, their larger format may accommodate bulky retail products or grouped lightweight items.

Keep the packing method specific to each product. Two orders can fit the same carton while requiring different levels of cushioning.

For stock storage, label each box with a clear description or reference. As a result, your team can identify the contents without opening every package.

These cartons may also help organise household textiles and selected belongings during a move. Nevertheless, assess the packed weight and avoid concentrating too many dense items in one box.

Group contents by room, product type or destination where practical. This can simplify unpacking and make stored goods easier to locate.

Storing Double Wall Cartons 450x450x516mm

Keep unused cartons in a clean, dry indoor area. Protect them from leaks, damp floors and locations where condensation may develop.

Avoid unnecessary crushing before use. In addition, keep heavy objects away from stored cartons if they could damage the panels or creases.

For packed storage, choose a stable surface that supports the carton’s base. Position labels where you can see them easily.

Do not assume double-wall construction makes every packed carton suitable for the same stacking arrangement. Instead, assess the box condition, contents and pressure from packages above it.

Avoid unstable stacks or arrangements that obstruct access. Larger cartons need sufficient space for retrieval and handling.

Inspect stored boxes periodically for moisture or damage. If a carton becomes weakened or distorted, transfer the contents into suitable replacement packaging.

Before reusing a carton, check its base, sides and closure areas. Reuse it only when its condition suits the next application.

Food Safety Information

Use these cartons as secondary packaging when food already has suitable food-contact packaging around it. Do not place unpackaged food directly against the cardboard.

Keep inner food packaging securely closed before packing. In addition, separate packs where contact could damage their seals or surfaces.

Store cartons away from chemicals and other potential contaminants. If the contents could leak, use suitable sealed inner packaging.

These cartons do not provide temperature control. Therefore, chilled or frozen products need a complete packaging and delivery system suited to their temperature requirements.

For specialist food-packing applications, discuss your requirements with us before ordering.

PPWR Compliance Information

The EU Packaging and Packaging Waste Regulation, Regulation (EU) 2025/40, concerns packaging placed on the EU market. Its requirements apply on a phased basis, so businesses should check the provisions and dates relevant to their activities. Further information appears in the European Commission’s packaging guidance.

Choosing an appropriately sized carton can help avoid unnecessary empty space. However, carton selection alone does not establish compliance.

Assess the complete package, including fillers, tape, labels and inner packaging. Your supply-chain role and destination market also affect the requirements you need to consider.

This description is not a declaration of PPWR compliance. Contact us for available product information and obtain appropriate advice for your specific obligations.
