Frozen Products
Packing requirements
The packaging material must be able to support a stacking height of up to 2.4 meters(7’10). 		Ventilation
When frozen products are transported, the fresh air ventilators must always be closed.
Stowage
The stowage of frozen products is very simple. The only requirement is a solid block stowage, leaving no space between the packages and no space between the cargo and the walls of the container. Most importantly, the cargo should be stowed below the red load line as this allows the refrigerated air to circulate evenly around the cargo, thereby maintaining the frozen products at the required temperature.

Chilled Products


Packing requirements
The packaging material must be able to support a stacking height of up to 2.4 meters (7’10). The material should be able to withstand humidity without collapsing and should allow the passage of vertical air flow through the cartons, in order to maintain the required. As the air flow comes from the bottom of the container, circulation will the optimum air be achieved if each carton has symmetrical hole at both top and bottom.

Ventilation
The ventilation of chilled products is necessary in order to remove the heat, carbon dioxide and gases produced by the cargo. Heat is removed by continuously circulating the internal air, whereas carbon dioxide and gases are removed by replacing the internal air supply with cooled fresh air.
Stowage
The live chilled products respires to produce heat, water vapor, carbon dioxide and gases, which may deteriorate the product and should therefore be removed. The stuffing should allow the refrigerated air to circulate through the packaging material and throughout the entire load.
There are two standard loading patterns for chilled products:
Palletized cargo stowage
The products should be stacked in solid block way, without any space between the cargo and the walls of the container. If the cargo cannot cover the entire floor area, heavy cardboard must be placed in the empty space. This will prevent the air from “ short - cycling”, which means finding the easiest way, resulting in the insufficient cooling of the cargo. Cargo may not be stowed above the red load line. This is in order to ensure proper refrigerated air circulation. 		Block stowage
The guidelines of block stowage should be followed, and the following points are recommended: The cartons must be stacked squarely on top of each other, in order to ensure that the weight is evenly distributed on the four corners of the cartons. The ventilation holes, located at the top and bottom of the cartons, must be aligned in order to allow the air to pass through the entire load. It is not recommended to use shrink-wrapped pallets, slip sheets, foam trays, plastic bags or similar materials which may obstruct and block the air circulation through the cargo.
