Cardboard packing boxes are a simple and smart choice for packing, shipping, and storage. They come in all shapes and sizes. You’ll find brown and white boxes, strong double wall boxes, and even custom printed options.

You can use them to move house, store clothes, or ship online orders. Cardboard boxes help keep your things safe and make packing easier. In this guide, we’ll show you the best types of boxes, what they’re made of, and how to use them. It will also help you pick the right one for your needs.

What Are Cardboard Packing Boxes?

Cardboard packing boxes are made from thick paper called corrugated cardboard. They are strong, light, and easy to use. People use them to move, store, or ship things.

There are many types. These include single wall boxes, double wall boxes, storage boxes, removal boxes, and postal or packaging boxes. You’ll often see them used in homes, shops, and warehouses.

Materials and Structure

Most cardboard boxes are made from corrugated cardboard. This material has three layers: two flat outer sheets and a wavy inner layer called “fluting.” This wavy part adds strength and helps absorb shock.

Some boxes use a single wall, and others use two layers (double wall). The more layers, the stronger the box. That’s why double wall cardboard boxes are great for heavy or breakable items.

Single Wall vs Double Wall Cardboard Boxes

Single wall boxes are made with one layer of corrugated cardboard. They are light and low-cost. They work well for small items or parcels that don’t need much support.

Double wall boxes have two wavy layers between three sheets of board. This makes them much stronger. They are perfect for moving, shipping heavy items, or stacking boxes on top of each other.

In fact, tests show that double wall boxes can carry up to 50% more weight than single wall ones. They also last longer in storage and are less likely to bend or tear.

Standard Boxes (Brown & White)

Brown cardboard boxes are affordable and ideal for moving and everyday storage. White cardboard boxes look cleaner and are often used in retail displays or branded shipments.

Book Wrap Boxes: protect flat items like books and documents.

Letter Size PiP Boxes (Royal Mail): fit official small mail parcels.

Small Parcel Boxes (Royal Mail): perfect for lightweight ecommerce orders.

These boxes improve protection, branding, and correct postal sizing.

Choosing the Right Box for Your Packaging Needs

Pick a box based on its function and what you're packing to ensure protection and cost‑effectiveness.

Based on Purpose

Moving boxes are designed for stacking and handling heavy home goods. Storage boxes suit archiving papers, linens, or seasonal decorations. Mailing boxes and postal boxes meet postal regulations and fit neatly on shelves. Pallet boxes offer bulk shipment capability, while bottle boxes cater to shipping wine or fragile bottles.

Based on Size & Strength

Choosing the right box size reduces wasted space and cost. Small box options (e.g., 12″ x 9″ x 6″) are great for books or small kitchen items. Large boxes (e.g., 24″ x 18″ x 18″) handle bulky pillows or equipment. Strength ratings, like single wall vs. double wall, affect how much weight and stacking the box can safely take.

Sustainability and Custom Options in Cardboard Packaging

Modern packaging prioritises both function and responsibility. You can choose recycled options or custom designs that reflect your brand.

Recycled & Eco‑Friendly Cardboard Boxes

Recycled cardboard boxes reduce environmental impact and are widely recycled themselves. They’re strong enough for most moving, storage, and shipping needs while supporting eco‑friendly packaging.

Custom Cardboard Boxes for Branding

Custom cardboard boxes— including white postal boxes—allow printed logos, designs, and tailored sizing. These help brands create a premium unboxing experience, increase recognition, and reduce shipping waste by matching product dimensions.

Packing Materials & Tips for Efficient Packing

Smart packing uses the right materials and techniques to protect items and save space.

Essential Accessories for Box Packing

Packing tape or packaging tape secures box flaps reliably. Label boxes clearly. Use mailing bags for lightweight items, bubble wrap around fragile products, and packing paper as filler to stop movement inside the box.

Tips for Packing Heavy or Fragile Items

Place heavier items at the bottom and lighter ones on top. Add cushioning around delicate goods. Utilize archive boxes for document storage or sturdy pallet boxes for bulk shipping. Tell customers to keep a box’s side dimensions between 15–25 kg for easier handling.
