The packing method and the containers must permit a satisfactory volume of airflow with a reasonable pressure difference across the stack (Mitchell et al. 1971; Wang and Tuunpun 1968).

Packs in which spaces between products are occupied by packing material (such as paper wraps, bags, punnets, etc.) restrict airflow and slow cooling.

Unvented, plastic-film box liners prevent air from passing through a pack and cause very slow cooling. This is nothing new and is known since the early 70's.

We tackled this problem where it should be tackled. Tried. Tested. Proven. Simple.
