300 - 399mm Double Wall Cardboard Boxes

Find the best fit with added box thickness for high-strength protection

Eliminate unused space and reduce delivery costs by choosing a stronger and better-fitting box from our robust range of double wall standard cardboard boxes.

Reduce Costs with our 300-399mm Standard Cardboard Box Sizes

Don’t get caught out by the extra delivery costs that come with shipping items in bigger box sizes. At Davpack, we’ve created a collection of 300-399mm standard cardboard box sizes so you can find the best fit for your goods. Designed for cost-effective and space-efficient packaging, these medium-sized boxes keep excess space to a minimum – perfect for boxing up anything from electronics, toys and home equipment to mechanical parts and components.

Stock Up and Save with BIG Bulk Buy Discounts on 0201 Boxes

Take advantage of our bulk buy deals to stock up for less. The more standard double wall cardboard boxes you buy, the more you save. And because all our boxes are supplied flat-packed, you can order in large quantities without using up too much storage space. Our classic 0201 box design enables quick and easy assembly – simply fold the top and bottom flaps into place and secure them with packaging tape or carton box sealer.

Standard Cardboard Boxes Strengthened with Double Wall Thickness

Our standard cardboard boxes are designed to offer greater protection for heavy or fragile contents. The double wall thickness increases crush resistance for extra stacking strength while providing an additional barrier to withstand bumps or knocks. Like all our double wall cardboard boxes, they’re designed to hold loads of up to 30kg while retaining the lightweight flexibility of single wall alternatives. These standard 0201 boxes are ideal for e-commerce and retail store deliveries, but equally suitable for storing or shifting heavier items at home or in the workplace.
