ecommerce mailer boxes

Ecommerce mailer boxes are self closing corrugated boxes designed to protect products in the post while presenting the sender brand clearly, and ecommerce mailer boxes are the workhorse packaging for UK online shops sending clothing, cosmetics, gifts and small goods. Custom Postal Boxes manufactures mailer boxes in Wolverhampton to your size and print, with low minimum order quantities and free UK delivery.

Why ecommerce mailer boxes suit online retail

A mailer box folds from a single piece of corrugated board into a rigid carton with a hinged lid, so it needs no separate lid and packs quickly at the bench. The fluted board cushions knocks, resists crushing in a delivery van and keeps its shape far better than a mailing bag for goods that crease, chip or leak. Because the box is both the shipping pack and the presentation pack, the customer opens one item rather than layers of packaging, which feels tidy and reduces waste. A printed exterior also identifies the sender on the doorstep and inside the home, where a plain carton would say nothing about your shop.

Protection features buyers should check

Look for a board grade matched to the weight of your product, a lid that tucks or sticks firmly closed, and an internal size that holds the product still. Fragile goods may need a fitment or wrap, while soft goods such as clothing often need only the box and a sheet of tissue for presentation.

Choosing between tuck in and self seal closures

A tuck in lid folds and locks without tape, which suits brands that want a clean look and easy opening. A self seal strip gives a faster pack and a tamper evident close, and a tear strip can be added so customers open the box neatly without scissors.

Sizes and postal bands for mailer boxes

Mailer boxes are made to order, so the internal size can follow your product range rather than force your products into a stock size. Slim boxes can be designed for the Large Letter format, while most orders fit the Small Parcel band. The Royal Mail size and weight guide sets a Large Letter at up to 35.3cm by 25cm by 2.5cm and 750g, and a Small Parcel at up to 45cm by 35cm by 16cm and 2kg. Designing just inside a band can keep postage in proportion across thousands of orders. Browse Cardboard Mailer Boxes and Self Seal Mailer Boxes to compare everyday formats.

Print that earns its place on a mailer

A clear logo, your web address and one strong brand colour will outperform a crowded design on a moving parcel. Inside print can carry a thank you note, returns guidance or a prompt to reorder. Keep handling information legible and place barcodes or labels on a flat panel so scanning stays reliable in the delivery network.

FAQs about mailer boxes for online shops

What are ecommerce mailer boxes used for?

Ecommerce mailer boxes are used to ship online orders safely while presenting the brand. Their corrugated board protects goods in transit, the hinged lid packs quickly and the printed surface carries your logo and messages to the customer doorstep.

What size mailer box should I choose?

Choose a box slightly larger than your product plus its protective wrap, and check the outer size against your postal band. Many UK orders fit the Royal Mail Small Parcel limit of 45cm by 35cm by 16cm and up to 2kg.

Are mailer boxes strong enough for fragile products?

Mailer boxes made from suitable corrugated board protect many fragile goods, especially with a fitment or cushioned wrap inside. Share the weight and fragility of your product when you enquire so the board grade can be matched to it.

Can mailer boxes be recycled after delivery?

Corrugated mailer boxes can be recycled with household cardboard when they are clean and dry. Customers should remove plastic tape and labels where possible, and paper tape can be left in place in many collection schemes.
