Insulated distribution solutions

Recyclable insulated box is easy to assemble northbox Cascades

northbox®: raising the bar for direct to consumer

Designed for parcel shipping temperature-sensitive products, this recyclable insulated box is easy to assemble, ship and recycle. And thanks to the new northbox XTEND keeping food fresh during long transit or in regions with higher temperatures, while requiring less ice.


northbox®OCEAN™: a leakproof, rigorous sustainable alternative

Made with an innovative leakproof insulator to ensure fish and seafood stay fresh in transit, it’s the ultimate sustainable alternative to non-recyclable packaging.

Cascades is the partner of choice in sustainable packaging solutions

Easily recyclable solutions

For consumers

northbox is easy to recycle in just one step. The entire box, including the insulator, can be put in a recycling bin, with no need to remove the reflective film. The end users are concerned more than ever about their impact on the environment. As pioneers, we set the bar high for direct-to-consumer ecodesigned packaging. The whole Cascades northbox® collection is made from recycled content and How2Recycle® has prequalified the solution as widely recyclable in Canada and in the United States.

For mills

Our insulated packaging is completely safe for recycling equipment, and paperboard created from northbox fibres is of the same quality as that made entirely from OCC from other sources. The quality of this raw material is mill-approved.


Walking the talk


Cascades is deeply committed to reusing or preserving materials for our insulated solutions. We always integrate a maximum of recycled materials and continually develop recyclable packaging innovations that maintain freshness and reduce food waste.

We also go the extra mile to ensure our converting operations are sustainable, using the services of EcoVadis to regularly evaluate our suppliers.

In 2021, our customers helped us save at least 17,708 tonnes of wood, which is the equivalent of 116,900 trees.

It’s all part of what makes us one of the world’s 100 most sustainable companies, as recognized by Corporate Knights.

Insulated Boxes very rigid

Source of value

Our insulators are designed to be extremely rigid, which improves the stacking strength of the box they are placed in. Using our insulators allows you to opt for more cost-effective boxes with a lower edge crush test (ECT).

Our tried-and-true testing

hours of rigorous testing

For more than 10 years, our experts have been conducting thousands of thermal tests to ensure the performance and reliability of our northbox insulated solution.


Daily, our dedicated team works to improve our product performance, reduce our environmental footprint and confirm it meets market requirements. We also examine each demand individually to understand your specific needs and cold chain. Your satisfaction is our biggest priority.

Continuous improvement


  • Conduct daily thermal tests, ISTA 7E among others
  • Reduce dimensional weight
  • Improve eco-design through material optimization
  • Meet new delivery requirements: Amazon APASS and IATA tests for air transportation
  • Optimize box compression strength

Customized service


  • Laboratory reports for our customers
  • Ice optimization
  • Establish a personalized delivery profile
  • Rapid prototyping (compartments, separators, custom design)
  • Comparative analysis of materials
  • Assembly line analysis for product optimization

Our state-of-the-art tools


We have all the necessary thermal testing equipment in-house to ensure efficient northbox performance. We’ve developed our own calculator to simulate the effects of ice quantity, box size and outside temperature on delivery timeframes. Thanks to humidity control, our thermal chamber can even replicate tropical conditions to provide simulated delivery circumstances.
