HeatWave™ is a kraft paper pizza box insert designed to improve the quality of delivery and takeout pizzas: placed at the bottom of a standard box, it slightly elevates the pizza, promotes air circulation, reduces moisture, and limits direct contact with the cardboard to help retain heat longer.
Thanks to its innovative design featuring positive and negative hemispheres, HeatWave™ limits direct contact between the pizza and the bottom of the box. This air barrier helps retain heat longer while preserving the crust’s texture and the tasting experience upon arrival.
Results observed with HeatWave™ indicate that a 30 cm pizza equipped with the insert can stay up to 27% hotter after 15 minutes. A concrete advantage to enhance the perceived quality of your delivery and takeout pizzas.

By reducing moisture underneath the pizza, HeatWave™ helps preserve the crispiness of the crust during delivery or takeout. The pizza arrives hotter, less soggy, and more enjoyable to eat.
The insert acts as a grease barrier between the pizza and the outer box. It helps keep the cardboard cleaner and limits contamination from oils and fats.
HeatWave™ is placed directly at the bottom of the box, without gluing, folding, fastening, or extra equipment. It easily integrates into your existing pizza boxes and kitchen prep routines.
Made from responsibly sourced virgin kraft paper, HeatWave™ is recyclable and industrially compostable. It is manufactured in France, continuing Naturalvi’s expertise in kraft paper solutions.
As soon as it leaves the oven, a pizza naturally begins to lose its temperature, especially during delivery or while waiting to be eaten. In a standard pizza box, heat can dissipate through the bottom while moisture accumulates under the crust.
Thanks to its hemispherical relief, HeatWave™ keeps the pizza slightly above the bottom of the box and creates a ventilated air layer. This thermal barrier helps limit heat dissipation and maintain a higher temperature until arrival.

A hotter pizza means:
A delivery or takeout pizza can quickly become soft or soggy in poor conditions due to moisture trapped in the box.
Thanks to its dimpled design, HeatWave™ promotes air circulation under the pizza and helps limit moisture buildup. The crust thus better retains its texture, crispiness, and quality upon arrival.
Better crust quality upon arrival:

HeatWave™ also acts as a grease barrier between the pizza and the outer box. It helps limit cardboard contamination from oils and fats.
This protection helps keep the pizza box cleaner, improves the product’s presentation upon arrival, and facilitates better packaging management after use.
