What Are the Different Types of A3 Postal Boxes?

Need to ship A3 brochures, posters, or leaflets? Our single-wall cardboard boxes are made from durable corrugated board, providing lightweight yet sturdy protection for everyday shipping. Each box includes a sealable flap, keeping contents safe from dust and damage. For more fragile or dense items, our heavy-duty double-wall cardboard boxes offer a strong, crush-resistant structure, making them ideal for stacking, storing, or shipping delicate products.

What Is a Telescopic A3 Box?

For businesses that ship varying product sizes, our A3 reinforced telescopic boxes provide adjustable, flexible protection. These expandable boxes snugly fit around your items, reducing the need for void fill and offering extra security during transit. Need different dimensions?
