By removing oxygen, it increases the shelf life of the food.\n\n== Methods ==\n\nSeveral methods of vacuum packing exist:\n\n* vacuum bags can be used and filled with a liquid (ie wine bags)\n* (plastic) bags can also be filled with solid food if they are sucked vacuum afterwards using an air pump. Commercial systems exist for this. The bags are usually sealed using heat.\n\n== See also ==\n\n* [[Hand Operated Vacuum Packing System for Seed Storage]]\n\n== External links ==\n\n* Design of a diy, resealable wooden vacuum barrel + tap\n* [http://en.wikipedia.org/wiki/Box_wine A vacuum wine bag: another type of bottling]\n\n{{Page data\n| license = CC-BY-SA-3.0\n}}\n\n[[Category:Food storage]]"}
