Cardboard Postal Boxes for Ecommerce & Shipping
Whether you're sending ecommerce orders, gifts, clothing, cosmetics, electronics or smaller retail products, choosing the right postal box can make packing quicker and help protect your products during delivery.

 

ASC Direct stocks postal boxes in a variety of sizes, styles and colours, including brown, white and black postal boxes, alongside self-seal and specialist shipping-box options.

 

Many of our traditional postal boxes use the popular FEFCO 0427 design, which combines an integrated lid with tuck-in flaps to create a practical box that's easy to assemble.

 

Small & Large Postal Boxes
Choosing the right size is just as important as choosing the right style.

 

A box that's too small may not leave sufficient room for the protection your product needs.

 

A box that's unnecessarily large can create excess empty space, potentially requiring more void fill and taking up more storage space.

 

That's why our postal-box range includes a variety of dimensions for different products.

 

When choosing a box, measure the product and consider any protective wrapping, cushioning or inserts that also need to fit inside.

 

The aim is to choose the smallest appropriate box – not simply the smallest box the product will fit inside.

 

Brown Postal Boxes
Brown postal boxes provide a simple, practical option for everyday ecommerce and shipping.

 

Their natural appearance works particularly well for businesses that want straightforward packaging without additional decoration.

 

Available in a range of sizes, our brown postal boxes are supplied flat-packed for convenient storage and can be quickly assembled when required.

 

White Postal Boxes
White postal boxes offer the same practical approach with a cleaner presentation.

 

They're particularly useful where the appearance of the parcel is important or where you want to add your own labels, stickers or other branding.

 

Choose from a selection of sizes to suit different products and applications.

 

Black Postal Boxes
For businesses looking for something different from conventional brown or white packaging, our black postal boxes provide a distinctive alternative.

They're particularly suited to ecommerce, gifts and retail products where the presentation of the parcel forms part of the customer experience.

 

Whatever colour you choose, the most important considerations remain the same:

 

The box needs to fit the product and provide the protection it requires.

 

FEFCO 0427 Postal Boxes

Many of our stock postal boxes use the FEFCO 0427 design.

 

This die-cut box style features an integrated hinged lid and tuck-in sections, creating the familiar postal-box construction widely used for ecommerce packaging.

The boxes are supplied flat and assembled when needed, helping reduce the amount of space required for packaging storage.

 

FEFCO 0427 is particularly useful for smaller and medium-sized ecommerce products where quick assembly, protection and presentation are all important.

Self-Seal Postal Boxes

If packing speed is particularly important, consider our self-seal postal boxes.

 

Rather than relying on separate packaging tape to secure the box, selected designs include an integrated sealing strip.

 

This can simplify the packing process and can be particularly useful for ecommerce businesses processing larger numbers of orders.

 

Check the individual product specification to see the closure system included with each postal box.

 

Postal Boxes for Small Businesses
You don't need to be sending thousands of parcels every day to benefit from good packaging.

 

Our postal boxes are suitable for businesses of different sizes, including:

 

- Ecommerce retailers
- Etsy and eBay sellers
- Subscription businesses
- Independent retailers
- Handmade-product businesses
- Marketplace sellers
- Home-based businesses

If storage space is limited, consider how many different box sizes you genuinely need.

 

A smaller selection of appropriately sized boxes can often be easier to manage than storing numerous sizes that are rarely used.

 

Postal Boxes for Royal Mail & Parcel Couriers
Our cardboard postal boxes can be used for sending suitable products through Royal Mail and parcel courier networks.

 

However, don't choose a box simply because its dimensions are below a courier's maximum parcel size.

 

Courier limits are maximums – not recommended box sizes.

 

Start with the dimensions and protection requirements of your product, then check that the finished parcel complies with the current size, weight, packaging and contents requirements of your chosen delivery service.

 

Remember that courier dimensions normally relate to the external dimensions of the finished parcel, whereas packaging dimensions may be quoted internally.

If your parcel is close to a courier size limit, check the finished external measurements before sending.

 

Choosing the Right Postal Box Size
Before ordering your postal boxes, consider:

- What are the dimensions of the product?

- Measure its maximum length, width and depth.

- Does it require protective packaging?

- Allow sufficient space for any wrapping, cushioning or inserts required to protect the product.

- Will the product move excessively?

 

The contents should be appropriately secured rather than being allowed to move freely around a large box.

 

What are the courier requirements?

Check the finished parcel against the current requirements of the delivery service you intend to use.

 

Could a smaller box work?

If you're filling significant amounts of empty space every time you pack an order, consider whether another stock size would be more appropriate.

 

Stock Postal Boxes vs Custom-Sized Boxes
Stock postal boxes can be an extremely cost-effective packaging solution.

 

They're manufactured in predetermined sizes and larger quantities, so if you find a stock box that fits your product properly:

 

Use it.

 

You don't need custom packaging simply for the sake of having a custom box.

 

But if you're regularly compromising on size, using large amounts of void fill or struggling to find packaging for an unusually shaped product, made-to-measure packaging may be worth considering.

 

ASC Direct's online Box Builder allows you to specify the internal length, width and depth you require and order custom-sized corrugated cardboard boxes from just 25 boxes.

 

This gives you a choice:

Find a stock postal box that fits – or build a box around your product.

Printed Postal Boxes
Packaging can also form part of your branding.

 

We offer selected printed postal-box options for businesses wanting to add branding to their packaging.

 

A printed box can carry your logo or design and turn the packaging required to send your product into part of the customer experience.

 

For larger branded packaging requirements, explore our printed postal boxes or contact our team to discuss your requirements.

 

Responsible Cardboard Packaging
ASC Direct is FSC® certified, with Chain of Custody certification FSC-C218342.

 

Our ASC-manufactured corrugated boxes use FSC® Mix 70% material and contain a minimum of 70% recycled content.

Cardboard packaging can also help businesses reduce their reliance on plastic packaging, particularly when combined with appropriately selected paper-based protection and paper packaging tape.

 

But good packaging isn't simply about replacing one material with another.

 

It's also about using an appropriate amount of packaging for the product.

 

Choosing a postal box that fits properly can help reduce unnecessary empty space and the additional packaging used simply to fill it.
