Handbook of Australian Meat 7th Edition AusMeatInternational Red Meat Manual

Correct packaging of red meat is crucial to the overall quality and shelf life of the product,
which in turn affects the return to the customer/importer. The polythene covering (sheet or bag) must be of
a size to adequately secure the meat content for exposure to outer contamination or freezer damage.

The methods of packaging and symbols are outlined.

Indicates that the meat cut has been individually wrapped in an approved
material, such as a sheet, stock netting or bag. These are most commonly
used on larger primal cuts. Individually Wrapped uses the cipher ‘IW’.
Indicates the product is packed into a carton containing two or more layers
of meat with each layer separated by an approved material. Layer packed
meat is most commonly used to layer small cut items (e.g. Flank Steaks or
Backstraps). Layer Packed uses the cipher ‘LP’.
Multi Wrapped indicates the meat has been packed in a single bag or
covering and contains two or more cut items. This method is most commonly
used for small and medium sized primal cut items (e.g. Chuck Tenders –
Lamb Racks). Multi Wrapped uses the cipher ‘MW’.
Tray packed meat is when the meat is packed into an open container or
tray, and covered with a film. This is mainly used in smaller primal cuts or
portioned meat. Tray Packed uses the cipher ‘TP’.
Modified Atmosphere Packed indicates that packs (primal cuts or retail ready tray)
are wrapped and are flushed with a mixture of gases to remove the oxygen. The
packs are impermeable to gases and retain the modified gas atmosphere around
the meat to preserve the meat quality and shelf life by restricting the amount of
bacteria growth. Modified Atmosphere Packed uses the cipher “MAP”.

Vacuum Packed involves the removal of air and oxygen from the packaging. This
creates a vacuum and assists in the preservation of meat and improvement in
meat quality due to the lack of oxygen around the meat that promotes bacterial
growth. Vacuum packing is adapted to all methods of packaging, including:

  • Individually Wrapped – Vacuum Packed (IW/VAC)
  • Layer Packed – Vacuum Packed (LP/VAC)
  • Multi Wrapped – Vacuum Packed (MW/VAC)
  • Tray Packed – Vacuum Packed (TP/VAC)
