What is the Difference Between Single and Double Walled Boxes?

Our parcels go through a lot during transit. From rough handling to bumpy drives and damp delivery vans, using the right type of box is crucial for the safety of the items inside. Whilst triple walled boxes are used very rarely, single walled boxes and double walled boxes are two commonly used types of cardboard box which both serve as a great packaging choice, depending on your needs.

Understanding the differences between single and double walled boxes can help you to make an informed decision for posting parcels. So, read on for a full breakdown of the key distinctions between both types and our recommendations for when to use each type.

Single Walled Boxes

Single walled boxes are made from a single layer of corrugated cardboard. Typically, this will include an inner and outer layer with a fluted layer sandwiched in between to provide cushioning and help the box maintain its strength and shape.

When to Use a Single Walled Box

Lightweight, non-fragile items that are not vulnerable to water damage will typically be packaged in single walled boxes. These boxes offer adequate protection for less delicate items and are less costly than double walled boxes. Small household items, clothing, and books are all great candidates for single walled box shipping. If moisture damage is a concern for you, consider wrapping your item in a layer of plastic, such as a supermarket shopping bag, before sealing it inside of your box.

Double Walled Boxes

Double walled boxes are made from two layers of corrugated cardboard. This will usually involve an inner and outer layer with two fluted layers sandwiched in between. This provides an extra degree of cushioning compared to single walled boxes, increasing the durability and sturdiness of the box. This makes the box better for stacking and more resistant to crushing or puncturing.

When to Use a Double Walled Box

Double-walled boxes are ideal for heavier, more fragile, or higher-value items that require a greater deal of protection. Larger, heavier, more delicate items should be packaged in double walled boxes for the extra protection they offer. Electronics, machinery, and delicate homewares such as glassware are some prime examples of items which should be shipped in double walled boxes. This is also a good choice for items which will be travelling a long distance, or perhaps internationally, as they perform well in challenging environments and with rough handling during transit.
