Cardboard Postal Boxes for Every Need

Our range of cardboard postal boxes provides a versatile and secure solution for shipping a variety of goods. We supply these boxes in several durable materials, including three-layer corrugated cardboard in both E-flute and B-flute configurations, as well as solid board for more compact items. The base material comes in three standard options: classic brown kraft, clean white, or a combination of a white exterior with a brown kraft interior. This selection offers a solid foundation for any branding. These boxes are an excellent choice for businesses that require reliable packaging for their products, from small subscription items to larger goods. Many online brands use our packaging solutions, and you can browse our full range of e-commerce boxes to find options tailored to direct-to-consumer shipping requirements.

Customise Your Mailer Box

Personalising your mailer box is a straightforward process that helps your brand stand out. We offer full CMYK digital printing on both the outside and inside surfaces of the box, giving you complete creative control over the final appearance. This allows for the application of detailed logos, brand colours, and complex graphic designs. For a more premium finish, you can add hot foil stamping or a protective varnish to certain models. The Custom Mailer Box is a popular choice, offering a large canvas for branding and a secure, self-locking design. All customisation options are available with a minimum order quantity starting from just 30 units, making branded packaging accessible for businesses of all sizes.

A Range of Postage Boxes

The collection includes a wide variety of postage boxes to suit specific products and use cases. For shipping books, documents, and other flat items, the Custom Book Wrap Mailer offers an adjustable and secure format. Apparel brands can select from specialised packaging like the Custom Scarf Mailer Box or the Custom Lingerie Mailer Box with Hot Stamping, which provide an elegant presentation for delicate items. Each design considers both product protection and brand presentation, with structures that are easy to assemble and pack. We supply all our boxes from within Europe, ensuring consistent quality and supply chain reliability.

Mailer Boxes Wholesale and Bulk Orders

For businesses requiring packaging at scale, Packhelp operates as a supplier of mailer boxes wholesale. We provide competitive pricing on bulk orders, enabling companies to manage their packaging inventory cost-effectively. Ordering wholesale postal boxes ensures a consistent supply for your operations and allows for greater customisation possibilities on larger runs. Our platform simplifies the process of ordering large quantities, with clear pricing tiers and dedicated support for trade accounts. Whether you need a few hundred boxes for a product launch or thousands for ongoing fulfilment, we can accommodate your requirements.

Postal Box Packaging Specifications

Every piece of postal box packaging we supply adheres to strict technical standards. We use testliner materials with weights ranging from 380 to 460 gsm, providing robust protection during transit. A standard dimensional tolerance of plus or minus 2-4 mm applies to all our boxes, ensuring consistency across your order. These specifications confirm that the packaging will perform reliably.

Choosing Your Postal Boxes

Selecting the right postal boxes for your business involves considering product size, weight, and shipping method. Many of our boxes are sized to fit standard courier and Royal Mail formats, which can help manage postage costs. With the ability to order from just 30 units, you can test different sizes and designs without a large initial commitment.

FAQ

Do mailer boxes close without tape?

Yes. Mailer boxes have locking flaps, and selected models add an adhesive strip, so they close securely without tape. This makes packing fast and gives a tidy, ready-to-ship box.

Are mailer boxes suitable for returns?

Yes. Selected mailer boxes have a double adhesive strip: you seal the parcel with the first strip, and your customer reseals it with the second for a return. They can send the item back in the same box, with no new packaging needed.

What are mailer boxes made of?

Mailer boxes are made from corrugated cardboard (flute B, E or BC), light yet rigid, which protects the contents in transit. You can order them in kraft or white and print them in full colour, inside and out.

What is the minimum order for mailer boxes?

You can order custom-printed mailer boxes from as few as 30 pieces per order, so there is no large minimum to start. The price per box drops as the quantity grows. The exact minimum for each model is shown on its product page.

What sizes are mailer boxes available in?

Mailer boxes come in a range of standard sizes, roughly from 9 x 9 x 5 cm up to 42 x 52 x 18 cm, and can also be made to your own dimensions in the editor. Pick a size that fits your product snugly for a tidy unboxing and less filling. The sizes for each model are on its product page.
