Black Mailer Boxes

Black mailer boxes give shipped products a stronger visual identity without compromising the practical requirements of ecommerce packaging. Built from durable corrugated board, they provide a secure format while giving customers a more considered unboxing experience. 

We produce black mailer boxes in bespoke sizes, with branded printing and box structures matched to the product being packaged. There is no minimum order quantity, so you can order the quantity your business actually needs rather than tying up budget in excess stock.

Custom Black Mailers Designed Around Your Brand

Your packaging should make your products look worth opening. Our branded black mailer boxes give fashion, beauty, gifts, subscriptions, and retail brands a distinctive outer package that strengthens presentation from the moment it arrives. 

Custom black mailer boxes give businesses control over how their packaging looks and feels. Add your logo, artwork, brand colours, product details, or inside print to create an unboxing experience that feels consistent with your brand identity. 

From minimalist luxury design to bold packaging, choose printing and finishing options that suit your market position. Custom sizes and structures allow the box to be developed around your products rather than forcing them into standard formats. 

Reliable Protection for Products during Delivery

Every product has different packaging requirements. A lightweight clothing order, cosmetic set, candle, accessory, or gift item needs a box structure that provides the right balance of fit, protection, and presentation. 

We manufacture black mailer boxes in customised dimensions with corrugated construction and secure self-locking designs to support reliable ecommerce despatch. You can select the right flute option based on your product weight, size, and shipping requirements. This helps you maintain product protection without unnecessary packaging bulk. 

Where products need additional organisation, custom inserts can be incorporated to reduce movement, separate items, and create a more structured unboxing experience. Bespoke sizing is especially useful for brands with multiple SKUs, allowing each product to be packed in a suitable format rather than relying on oversized standard cartons. 

E-Flute and B-Flute Corrugated Options

Our black mailer boxes are available in E-flute and B-flute options, allowing you to select a construction suited to the application. 

E-flute has a thinner profile and relatively smooth surface, making it well suited to detailed printing and premium presentation. It provides a practical option for lightweight and medium-weight products where presentation and efficient packaging are priorities. 

B-flute has a thicker profile that provides greater rigidity and cushioning. This makes it suitable for products that need additional support during storage, handling, and transit. 

Selecting the appropriate flute makes sure your black mailer boxes provide the right balance of strength, appearance, and shipping performance. 

Add Inserts for a More Secure Fit

Black mailer boxes can be customised with internal inserts when products require additional support, separation, or a more structured presentation. This is particularly useful for multi-item packaging, gift sets, and products where organisation is an important part of the customer experience. 

Integrated inserts keep products positioned during handling and delivery while making the unboxing experience more organised. Designed alongside the mailer box, they make sure the internal space is used efficiently without adding unnecessary packaging bulk. 

From simple product dividers to tailored internal layouts, inserts can be developed as part of your overall black mailer box specification.  

Precision Printing and Finishing for Brand Consistency

A branded mailer box needs consistent print quality and finishing to represent your business properly. Poor colour reproduction, inaccurate artwork placement, or an unsuitable finish can undermine an otherwise well-designed package. 

Our modern printing and finishing options help you achieve the appearance required for your brand, including matte and gloss finishes, foil details, and other enhancements where suitable for the chosen construction. 

Use a restrained logo treatment for a minimalist presentation or more extensive artwork to create a stronger branded parcel. With free 3D proofing, we allow you to review the proposed design, artwork placement, and structure before production.
