Bespoke Mailer Boxes Designed for Your Products

Every product has different packaging requirements. A box that works for clothing may not be suitable for cosmetics, candles or fragile products.

Our custom size mailer boxes are designed around the dimensions, weight and presentation requirements of your products. This allows you to create packaging that fits your products more effectively rather than relying on standard stock sizes.

You can specify:

• Custom length, width and depth
• Corrugated board type
• Flute specification
• Internal and external printing
• Brand colours and artwork
• Matt or gloss finishes
• Premium embellishments
• Custom inserts and dividers
• Tear-open or opening features
• Special structural requirements

If you are unsure which specification is right for your product, simply send us your product dimensions and requirements and our packaging team can advise you.

Branded Mailer Boxes for E-Commerce

Your packaging is more than a shipping container. It is part of your customer's experience with your brand.

Custom printed mailer boxes allow you to turn an ordinary delivery into a branded unboxing experience. Add your logo, colours, graphics, messaging, website address, social media details or campaign artwork to create packaging that customers recognise immediately.

Our mailer boxes are suitable for:

• E-commerce businesses
• Online retailers
• Subscription box companies
• Clothing and fashion brands
• Cosmetics and skincare brands
• Jewellery and accessories
• Gifts and lifestyle products
• Candle and home fragrance brands
• PR and influencer campaigns
• Product launches
• Small businesses and start-ups

Custom Printed Mailer Box Materials

We can discuss different board options depending on your product, required strength, appearance and shipping requirements.

Kraft Mailer Boxes

Kraft corrugated mailer boxes provide a natural and authentic packaging appearance. They are particularly suitable for brands looking for a simple, modern or environmentally conscious visual style.

White Corrugated Mailer Boxes

White corrugated board provides a clean surface for vibrant branding, detailed graphics and full-colour artwork. It is a popular choice for premium e-commerce and retail packaging.

E-Flute Mailer Boxes

E-flute corrugated board offers a relatively fine profile and is suitable for applications where presentation, rigidity and efficient packaging are important.

B-Flute Mailer Boxes

B-flute provides a deeper corrugated structure and can be considered where additional strength and cushioning are required.

The most suitable board depends on your product dimensions, product weight, shipping conditions and desired presentation.

Full-Colour Custom Printing

Make your packaging instantly recognisable with professionally printed artwork.

Your mailer box can include:

• Company logos
• Brand colours
• Product graphics
• Illustrations
• Photography
• Promotional messages
• Website addresses
• Social media details
• QR codes
• Product information
• Thank-you messages
• Repeat-order information

We can discuss CMYK and Pantone printing depending on the required artwork, material and production method.

Inside Printed Mailer Boxes

Don't leave the inside of your packaging blank.

Interior printing allows you to continue your branding throughout the complete unboxing experience.

You could use the inside of your mailer box for:

• Thank-you messages
• Brand stories
• Product instructions
• Promotional offers
• Care instructions
• Social media campaigns
• QR codes
• Product information
• Seasonal artwork

For premium e-commerce packaging, combining outside branding with inside printing can create a much stronger customer experience.

Custom Mailer Boxes with Inserts

Some products need additional support inside the box.

We can discuss bespoke internal packaging such as:

• Corrugated inserts
• Cardboard dividers
• Product separators
• Die-cut fitments
• Custom internal supports
• Product presentation inserts

Inserts can help keep multiple products organised and reduce unnecessary movement during transit.

If you are packaging bottles, jars, cosmetics, candles, accessories or multiple products together, tell us what you are packing and we can discuss suitable internal options.

Premium Finishes for Branded Mailer Boxes

Your packaging can be enhanced with a range of finishing options depending on the chosen board and printing process.

Matte Finish

Creates a clean, modern and understated appearance.

Gloss Finish

Provides a brighter surface and can enhance the visual impact of printed colours.

Soft-Touch Finish

Adds a smooth, premium tactile feel and is suitable for brands looking for a luxury presentation.

Foil Stamping

Add metallic details such as gold or silver to selected elements of your design.

Spot UV

Highlight logos, graphics or selected areas with a contrasting gloss effect.

Embossing and Debossing

Add texture and dimension to selected branding elements for a more tactile presentation.

Custom Size Mailer Boxes

We do not rely on one standard mailer box size.

Your packaging can be manufactured around your required dimensions.

For an accurate quotation, provide:

• Product length
• Product width
• Product height
• Product weight
• Number of products per box
• Required quantity
• Preferred material
• Printing requirements
• Finish requirements
• Insert requirements

If you already have packaging dimensions, send them with your enquiry.

If you do not know the correct box size, send us your product measurements and our team can help determine a suitable specification.

Minimum Order Quantity

Custom printed mailer boxes are available from 100 units, making bespoke packaging accessible to start-ups, smaller e-commerce businesses, product launches and established brands.

Larger production quantities are also available for businesses that require ongoing packaging supply.

This gives you an opportunity to check the artwork, branding, structure and overall appearance before your packaging moves into production.

Artwork for Custom Printed Mailer Boxes

You can provide your own packaging artwork for production.

Ideally, artwork should be supplied in a professional print-ready format with the correct dimensions, bleed, colour settings and image resolution.

If your artwork is not ready, send us your logo, brand information and packaging requirements so we can discuss the available design support.

Custom Mailer Boxes for Subscription Brands

Subscription businesses need packaging that works repeatedly and consistently.

Custom subscription mailer boxes can be designed around your monthly product selection, helping create a recognisable branded experience with every delivery.

Interior printing can also be used for monthly messages, promotional campaigns, product information or QR codes.

Cosmetics and skincare products benefit from packaging that combines protection with premium presentation.

Sustainable Mailer Packaging Options

For brands looking to reduce unnecessary packaging materials, we can discuss recyclable and responsibly sourced packaging options.

Depending on the final specification, available options may include:

• Corrugated packaging
• Kraft board
• FSC-certified paperboard
• Recyclable paper-based packaging
• Lightweight packaging options
• Plastic-reduction solutions

The recyclability and environmental performance of a finished package depends on the exact materials, coatings, finishes and local recycling infrastructure, so your sustainability requirements should be discussed before production.
