Abstract
A compression sack constituted by non-breathable front and back sheets and having an opening formed in a part of the compression sack. The opening includes an access port for articles and air outlet, and closing means provided therein for tight closing and opening purposes. The access port and air outlet are separated by a separating member at which the front and back sheets are firmly joined together. The separating member extends from a side of the opening inwardly of the compression sack, thereby forming a deaeration passage between the air outlet and the inside of the compression sack. A spot seal is provided more inwardly of the sack than the end at the interior side of deaeration passage, and the separating member is bent at the end of the interior side of the deaeration passage in a direction of the deaeration passage.
