Corrugated boxes with wax coatings are commonly used in the food packaging industry. The wax coatings work as a barrier for moisture, keeping food cold and fresh while ensuring the boxes are strong enough to support the product. However, wax-coated boxes are also known to have a negative impact on the environment – because wax coatings do not dissolve in water, they pose problems during the repulping process and cannot be recycled. In addition, fees are required to dispose of wax-coated boxes.
As today’s packaging becomes more eco-friendly and cost-effective, there comes a need for wax coating alternatives that have a more positive environmental and economic impact.
A Wisconsin-based testing lab, IPS Testing, is now the fourth North American testing lab that has been authorized for recyclable, non-wax coating certifications. That means the testing lab is approved to perform the Voluntary Standard for Repulping and Recycling Corrugated Fiberboard protocol, in order to certify materials that provide a wider range of sustainable packaging options for corrugated boxes.
