VENTILATION BOARD AND A METHOD OF FORMING A VENTILATION BOARD

摘要

The present invention provides a ventilation board having means for splitting level of the ventilation board for providing ventilation and/or insulation. The ventilation board when used to make a panel defining an enclosed space such as a box or carton for food packaging provides sufficient ventilation and/or insulation to the box so that water condensed from food vapors does not run onto the food in the box along with sufficient insulation so that the food in the box is kept warm.
