Square Double Wall Cardboard Boxes Product Details

Our square double wall cardboard box is an original take on our classic double wall packing box. You get all the benefits of two layers of resilient cardboard fluting combined with a square shape that is easy to stack, unload and can easily be handled by freight carriers. Save up on copious amounts of protective and void fill by choosing a fitted square box. The double layer also protects the products against drops, shakes, and – most importantly – side impacts while moving on conveyor belts.

Recommended for

  • Packing, shipping, and storing parcels that contain accessories, cosmetics, and electronic devices. The sturdy 5-mm corrugated cardboard is fully stackable, so you can make the best use of precious space during transportation or storage. The square shape makes handling stress-free and the maximum shipment weight of up to 15 kg (10 when stacked) ensures you can fit all the products your customer needs.

Specifications

  • Box thickness of 5 mm with a brown cardboard recycled paper quality up to 100gsm

  • All dimensions shown are internal dimensions

  • 100% recyclable corrugated board made from recycled fibers

  • Those products are not designed to be used for heavy duty products unless stated otherwise, not to be used under high humidity or high temperatures conditions

  • All dimensions may vary by up to 3mm

Key Features

  • Heavy and delicate products remain safe

    Keep your fragile products or heavy items secure with a packaging that is designed to be sturdy so as to ensure the shipment arrives in one piece. Compared single wall boxes, double wall boxes hold heavier products of up to 15 kg or 10 kg for stacked shipments. Your customer will be delighted to receive products in excellent condition thanks to the five layers of alternating paper and flute.

  • Sustainability at the core

    DS Smith pursues sustainability at every level and its packaging is sure to reinforce your brand quality. Our recycled is 100% eco-friendly since the fibres can be recycled into more boxes after only 2 weeks. We handle over 5 million tonnes every year – that is the weight of 25,000 jumbo jets!

  • Made to be reused

    The square double wall carboard boxes made up of five layers – an outer layer of paper + a layer of flute + a layer of paper + another layer of flute + an outer layer of paper. This means these boxes are extremely durable and sturdy enough to be used multiple times. This way you can keep your waste to a minimum and your business as efficient as possible.

How to measure a box?

When measuring a cardboard box, it is important to consider three key dimensions: length, width and height. These measurements provide the internal dimensions of the carton, allowing you to define the space available to pack products and ensure they fit properly.

The dimensions provided on our website are in Millimetres and are following the order LENGTH x WIDTH X HEIGHT.

To measure correctly a cardboard box follow these instructions:

1. Length: start by measuring the longest side of the box base

2. Width: rotate the box 90 degres and measured the other side of the box base

3. Height:measure the distance from the base to the top

What makes ePack sustainabile?

In today's society, sustainability has become a key focus. Consumers who are conscious about the environment are demanding eco-friendly packaging solutions. DS Smith ePack offers packaging solutions that are 100% eco-friendly, using fibres from responsible sources to combat deforestation. They use recycled or virgin paper from a certified chain of custody, and their corrugated cardboard packaging is both recyclable and biodegradable.


DS Smith ePack prioritizes sustainability by using responsible sources, recycled or virgin paper, and recyclable and biodegradable materials. Consumers consider sustainability as a crucial factor in their purchasing decisions, and non-sustainable packaging can lead to negative consequences for companies. Eco-friendly packaging not only benefits the environment but also improves brand image and reduces the carbon footprint.

What is our Circular Design Metrics?

One of the most important principles of the circular economy is designing for circularity, which involves products and services being designed with their end-of-life in mind, making it easier to recover and regenerate materials.

DS Smith has developed a series of circular design metrics which give us an accurate picture of the degree of implementation of circular design principles in the production of our packaging solutions and provide quantifiable data to show how circular a given packaging solution is and allow quick identification of the areas of improvement required.

Our Circular Design Metrics measure Supply Chain Optimisation, Recyclability, Planet Safety, Material Utilisation, Renewable Sources, Recycled Content, the Carbon Footprint and Design for Reuse.

* This circularity information was made by using the information of an average double wall box.

What does FSC label means?

FSC (Forest Stewardship Council) labelled paper is an important choice for individuals and businesses looking to prioritize sustainability and responsible forest management. Using FSC labeled paper offers numerous benefits. It supports responsible forest management, reduces environmental impacts, promotes social responsibility, meets consumer demand for sustainable products, and ensures compliance with regulations and standards. By choosing FSC labeled paper, individuals and businesses can make a positive impact on the environment and contribute to a more sustainable future.

Postal Guide

This allows your business to keep the processing of orders and shipping as streamlined as possible, saving you time and money.
