Protect products with a secure mailer box

The Plain Mailer Box with Custom Sleeve is a versatile packaging solution designed to secure and present your products effectively. It features a sturdy corrugated cardboard box, available in both kraft and white, complemented by a customisable sleeve. This combination ensures your items are well-protected during transit and arrive in excellent condition. Ideal for a wide range of products, from apparel and cosmetics to electronics and gourmet foods, these boxes are built to handle the rigours of shipping.

Choose your ideal size and finish

These mailer boxes come in two practical sizes: medium and large, accommodating various product dimensions. You can select a box in either a natural kraft finish or a clean white, depending on your brand's aesthetic. The accompanying sleeve is available in kraft, white, or economy white options, providing further flexibility in material and appearance.

Branding that makes an impact

The custom sleeve allows for full multicolour CMYK printing on the outside, transforming a standard mailer box into a branded experience. This is an effective way to showcase your logo, brand colours, and unique designs, ensuring your packaging stands out. The sleeve offers a prominent canvas for your branding message.

Optimised for standard shipping

Our plain mailer boxes are engineered to fit standard courier and parcel-locker sizes, including services like InPost, DPD, Royal Mail, and DHL. This careful design ensures compatibility with common shipping infrastructure, simplifying your logistics and reducing potential issues with oversized packages. The secure fit helps prevent shifting during transit.

KraftKraft Paper is a brown-colored material which gives a organic, rustic appearance. This type of material is commonly used for packaging products that benefit from a natural or "green" presentation.
WhiteThis product is available in white.

Sleeve KraftKraft 300gsm is brown paper, without option of white ink print, and colors appear less saturated than on white paper.
Sleeve WhiteThe GC1 300gsm is a double-sided white paper.
Sleeve Economy WhiteThe GD2 300gsm is single-sided white and less bright compared to GC1 (Sleeve White)

Can I order custom sized sleeves?

Yes, sleeves tailored for custom sizes of mailer boxes are available upon filling out the form on our website.

Can I order just the sleeves?

No, not with this current product. But you can request a custom solution by sending us a brief. Our packaging experts will take you through your options.

Are sleeves made from the same material as boxes?

Sleeved mailer boxes are made from two types of materials. Sleeves, which cover the outside walls, are made from cardstock – a light paper material. Boxes, on the other hand, are made from corrugated cardboard.

Can I order white boxes with white sleeves and natural kraft boxes with natural kraft sleeves?

Yes! Up to four different sleeve packaging combinations are available for custom sleeve boxes. We recommend matching white + natural kraft, but you can also go for one of the other options.

Can I design custom sleeve boxes with the Packhelp editor?

Yes! Packhelp’s free designing tool lets you design your sleeve packaging boxes online, and most of our other packaging solutions, too!

What is the difference between the white and the natural kraft material?

Both white and natural kraft are made from the same material, cardstock. Cardstock (or sometimes just called “card”) is lighter than cardboard, has a lower grammage and doesn’t include fluting (layers made from recycled paper). The white cardstock is recommended for vivid and detailed designs. The natural kraft option works best for minimalist designs or along with darker colours – deep brown, black or navy blue. Check out the Inspirations page to see the differences between white and natural kraft wine boxes, or order a sample pack and check it out in the flesh.

Do you offer standard package sizes for shipments by carriers such as DPD and DHL?

Trade ordinary packaging for custom sleeve boxes available in four different combinations. Our custom sleeve packaging is friendly to all budgets. Here’s why it’s a unique packaging solution for your e-commerce or retail brand:

Sliding off a sleeve from a box is like taking a bow off a Christmas present – except it doesn’t have to be December. Our custom sleeve boxes build anticipation and excitement in your customer’s mind and create that memorable unboxing experience. Custom sleeve packaging puts your branding in front of your customer and generates more excitement. Designing sleeves is effortless too. Head to our online editing tool to create all types of custom packaging within minutes. Think outside the box – perhaps witty text or a play on words. And once you’ve finished, watch your prints come out immaculate. We only use the best quality cardboard to manufacture our custom sleeve boxes.

Our custom sleeve box comes in various sizes and combinations to guarantee your product’s exquisite look. It works excellent as a cosmetic box, gift box or shipping box for subscription sets, mugs, clothes, shoes, beverages, books, etc. You don’t have to commit to large quantities either. Order as few as 30 pieces and buy the same design in bulk when the time comes. Adjust your order size to your business and keep less money tied in custom-branded packaging.

Packhelp’s custom sleeve boxes add extra class and security to your packaging. Pick a natural or white cardboard box, and place your branding on a perfectly-sized sleeve that slides over it. Your custom sleeve packaging comes in either white or kraft and can be paired with a white or kraft mailer box. You can let your creativity flow with four combinations of custom sleeve boxes to choose from and bespoke box sleeve printing. Are you looking for some strong contrast? Use a natural kraft box and place your branding on a white sleeve. Are you looking for something delicate and innocent? Use a white box to complement a realistic kraft sleeve with plain black ink.

Our custom sleeve boxes are all about sturdiness and eco-awareness. Each sleeve is made to fit perfectly around its corresponding box, preventing the box from opening and keeping the contents secure. Each custom sleeve box is made from at least 70% recycled content. The extra thickness (300 g/m2) of the sleeve itself also adds some extra security and rigidity to your box. We also make them as eco-friendly as possible so that you can encourage your customers to upcycle or recycle your packaging.
