Which Cardboard Boxes Are Best for Shipping? | Packaging Advice from UK Experts

Which cardboard boxes are best for shipping?

Whether you run an e-commerce store or simply need to send a parcel to friends and family, choosing the right box can make all the difference in ensuring your items arrive safely while keeping shipping costs in check. But with so many options available, how can you decide which box is right for you?

Let’s look at some of the different types of boxes, how to choose the right size and strength, and why buying from a trusted supplier makes sense.

What are the most popular types of boxes?

Although boxes come in a wide variety of specifications, often designed for specific needs (e.g. book wraps, foam lined boxes, crash lock boxes, etc.), we’ll focus on the three most widely used options for shipping items in the UK. Here's a quick breakdown:

Single Wall Boxes

• Made from a single layer of fluted corrugated cardboard sandwiched between two flat liners.
• Cost-effective and sustainable, they’re widely used by businesses for general purpose shipping and storage.
• Ideal for lightweight or non-dynamic loads such as shoes, toys, clothing, etc. As a general rule, avoid using the medium to larger sizes to ship anything over 10kg.

Double Wall Boxes

• Constructed using two layers of fluted corrugated cardboard sandwiched between three flat liners.
• Heavy-duty and durable, these boxes are the preferred choice in the removals industry, ideal for both moving and international shipping.
• Great for heavy, fragile, or dynamic loads such as kitchenware, electronics, or multiple items packed together in one box.

Postal Boxes

• Typically, die-cut single wall boxes with a self-locking tuck-in flap for sealing (think of a pizza box, but designed for shipping items).
• Easy to assemble with an attractive presentation – they’re the go-to choice for e-commerce shipping, where packing efficiency and a positive unboxing experience matter most.
• Perfect for small to medium sized subscription boxes, gift boxes, or merchandise.

How to choose the right box size for your parcel?

Simply put, it depends on the size of the item you're shipping. Start by measuring the length, width, and height of the item, including any protective packaging (bubble wrap, kraft paper, etc.) you plan to use. Once you have your measurements, choose a box size that offers a snug fit to prevent shifting during transit – consider using packing peanuts or void fill paper if necessary. Avoiding oversized boxes not only helps reduce postage costs but also minimises environmental impact.

Can you recycle cardboard boxes?

Yes, most cardboard shipping boxes are made from recycled materials and are kerbside recyclable; however, boxes that are heavily contaminated with other materials like oil, grease, food residue or plastic may be harder to recycle properly.

Pro Tip: We recommend using paper-based tapes like kraft paper tape & water-activated gummed paper tape to help reduce plastic waste. Also consider flat-packing and storing boxes for future reuse.
