Buyer's Guide

Choosing the Right Corrugated Box

Match the flute to the job

E flute suits most printed mailers and e-commerce boxes. Step up to B or C flute for heavier shipping cartons, and double wall for heavy, fragile or high-value products.

Make the unboxing count

A printed mailer is often the first physical touchpoint with your brand. Print the outside for doorstep impact and the inside with a message or pattern for a memorable reveal.

Right-size to save money

Boxes made to your exact product size use less material, need less void fill and can lower dimensional-weight shipping charges. Send us your product dimensions and we will size it for you.

White or kraft liner?

A white liner gives bright, vivid print for branded mailers. A brown kraft liner is more natural and economical, and works well with one- or two-colour logos.

Product Description

Everything you need to know about our custom corrugated board boxes.

Custom Corrugated Boxes Made to Travel

Custom corrugated boxes protect your products from warehouse to doorstep. A fluted core between two liners creates a lightweight, rigid board that absorbs knocks, resists crushing and keeps contents safe through every step of delivery.

The Right Flute for Every Shipment

Choose F or E flute for slim, beautifully printed mailers, B or C flute for everyday shipping cartons, A flute for extra cushioning, or double wall for heavy and fragile goods. We recommend the best grade based on your product weight and how it ships.

Printed Mailer Boxes That Build Your Brand

Your shipping box is often the first thing a customer sees. Full-colour printing on white or kraft liners turns plain shippers into custom printed mailer boxes, and printing the inside adds a reveal that customers love to share online.

Right-Sized to Cut Shipping Costs

Boxes made to your exact dimensions use less material, need less void fill and help reduce dimensional-weight charges. Right-sized corrugated packaging saves money and looks more professional on arrival.

Recycled and Recyclable

Corrugated board is usually made with recycled fibre and is one of the most widely recycled packaging materials, making it a responsible choice for e-commerce and retail brands alike.
