Single Wall Cartons 305x229x51mm

Our Single Wall Cartons 305x229x51mm offer a shallow rectangular format for everyday packing. They provide an alternative to deeper boxes when your protected contents need a broad base but limited height.

Choosing a carton close to the size of your wrapped goods can help avoid unnecessary empty space. Consequently, you may need less void fill than you would with a much deeper box.

The cardboard outer package forms one part of the complete packing system. Suitable wrapping, cushioning and secure closure also contribute to protecting the contents.

For repeat orders, prepare a trial pack using your actual products. This helps you establish a consistent method while allowing for the space needed around each item.

We can discuss carton sizes and complementary materials with you. However, always assess the finished package against its intended handling conditions.

Single Wall Cartons 305x229x51mm Dimensions and Specifications

• Product type: Corrugated cardboard carton.
• Construction: Single wall.
• Metric dimensions: 305mm x 229mm x 51mm.
• Approximate imperial dimensions: 12.01 x 9.02 x 2.01 inches.
• Dimension order: Width x depth x height.
• 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 retail packaging or separators that will remain inside the box.

The shallow height makes a practical fit test particularly useful. Check that the protected contents fit without forcing the top closure upwards.

For close-fitting items, check the usable internal dimensions with us before ordering. The nominal size alone does not guarantee a comfortable fit.

Understanding Single Wall Cartons 305x229x51mm 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 any cushioning beneath or above them.

Flat products can still need additional packing space. For example, a picture frame may require corner protection and cushioning on both faces.

If several items will share one carton, arrange them as you intend to pack them. Likewise, include any separators needed to prevent contact between products.

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

Do not assume the shallow profile guarantees letterbox suitability or a particular postal rate. Check the finished package against your chosen carrier’s current requirements.

Choosing Single Wall Cartons 305x229x51mm

Single Wall Cartons 305x229x51mm may suit goods that fit comfortably within a shallow rectangular package. Start by checking the protected dimensions and intended arrangement.

Consider the weight, shape and fragility of each item. In addition, think about whether the carton will travel individually or inside a larger outer package.

Slim textiles may need simple containment and separation. Delicate framed products, by contrast, can require cushioning around their edges and faces.

Avoid choosing this shallow size if adequate protection makes the contents too tall. A deeper carton may provide a better fit without compressing the product or wrapping.

Dense components can place concentrated pressure on the base. Similarly, sharp edges need suitable protection to prevent damage to the cardboard or neighbouring items.

Before regular use, test a representative pack. This allows you to assess the complete combination of carton, contents, cushioning and closure.

How to Assemble Single Wall Cartons 305x229x51mm

Prepare a clean, dry packing surface and gather the materials you need. 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 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 Single Wall Cartons 305x229x51mm

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 items that could scratch, knock or press against one another.

For flat products, consider protection above and below the item as well as around its edges. Exposed corners may need particular attention.

Use suitable packing materials to occupy unwanted gaps. However, avoid forcing excessive cushioning into the carton, as this can distort the panels or prevent proper closure.

Do not compress fragile products to make them fit within the shallow height. Instead, choose a deeper box when the complete protected item needs more room.

Check for unwanted movement using a method appropriate to the goods. Once you are satisfied with the arrangement, seal the carton securely.

Apply a clear delivery label where the carrier and recipient can read it easily. Keep essential address information away from opening seams where possible.

Single Wall Cartons 305x229x51mm for Business, Storage and Removals

Single Wall Cartons 305x229x51mm can help organise suitably sized products within a business packing routine. For example, one shallow carton size may accommodate several slim products with similar protected dimensions.

Keep the packing method specific to each item. Two products can fit the same box while requiring different levels of cushioning.

For stock storage, add a clear description or reference to each carton. As a result, your team can identify the contents without opening every package.

These boxes may also help organise smaller flat belongings during a move. Nevertheless, assess the packed weight and choose suitable alternative packaging for demanding removal tasks.

Avoid placing heavy items directly onto delicate contents. Separate cartons or appropriate dividers can make protection and handling more straightforward.

Storing Single Wall Cartons 305x229x51mm

Keep unused cartons in a clean, dry indoor area. Protect them from leaks, damp floors and places 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 and position labels where you can see them. Place heavier packages below lighter ones where appropriate.

Do not assume the shallow shape makes every packed carton suitable for stacking. Instead, assess the box condition, contents and pressure from packages above it.

Inspect stored cartons periodically for moisture or damage. If a box 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.

Sample Requests

A trial pack can help you assess suitability before placing a larger order. In particular, use your actual products, wrapping and closure method when checking the carton.
