Single Wall Cartons 305x229x102mm

Our Single Wall Cartons 305x229x102mm offer a shallow rectangular format for everyday packing. Their proportions provide an alternative to deeper boxes when your protected goods need more base area than height.

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

These cartons form the outer part of your 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 without overlooking the space needed for protection.

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

Single Wall Cartons 305x229x102mm Dimensions and Specifications

• Product type: Corrugated cardboard carton.
• Construction: Single wall.
• Metric dimensions: 305mm x 229mm x 102mm.
• Approximate imperial dimensions: 12.01 x 9.02 x 4.02 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 space 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 items, check the usable internal dimensions with us before ordering. A nominal size alone does not guarantee that your wrapped product will fit comfortably.

Consider the complete packed weight alongside the dimensions. The contents, cushioning and closure method all affect suitability.

Understanding Single Wall Cartons 305x229x102mm Measurements

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

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

Flat items can still require additional packing depth. For example, a framed product may need 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 the products.

The carton should close 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 contents without forcing them against the cardboard.

Choosing Single Wall Cartons 305x229x102mm

Single Wall Cartons 305x229x102mm may suit products that fit comfortably within a shallow rectangular package. Start by checking the protected dimensions and the intended packing 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.

Soft goods may need simple separation and secure containment. Delicate products, by contrast, can require cushioning around every side.

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

For more demanding applications, discuss alternative carton sizes or constructions with us. A different option may offer a better match for the goods.

Before adopting a carton for regular use, test a representative package. This allows you to assess fit, closure and protection together.

How to Assemble Single Wall Cartons 305x229x102mm

Prepare a clean, dry packing surface before assembling 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. The 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.

Add base cushioning before placing the goods inside. Then arrange 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 Single Wall Cartons 305x229x102mm

A suitable packing method helps keep products stable inside their outer carton. Therefore, choose protective materials 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 void fill to occupy unwanted gaps. However, avoid forcing excessive material into the box, as this can distort the panels or prevent proper closure.

Check for unwanted movement using a method appropriate to the goods. Do not shake fragile contents aggressively to test the pack.

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. This helps preserve the label when the recipient opens the package.

Single Wall Cartons 305x229x102mm for Business, Storage and Removals

Single Wall Cartons 305x229x102mm can support an organised packing routine for suitably sized products. For example, one carton size may accommodate several items with similar protected dimensions.

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

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

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

Avoid grouping heavy components with fragile products unless you provide effective separation. Separate cartons can simplify protection and handling.

Storing Single Wall Cartons 305x229x102mm

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 that every packed carton can support the same stacking arrangement. 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.

Samples may be available. Please contact us to discuss your requirements:
