BAG AND DEVICE OF FILLING CONTENT IN THE BAG

摘要

PROBLEM TO BE SOLVED: To provide an air permeable bag to which a content can be filled by using a filling device provided with a conventional suction type transfer means and to provide the filling device capable of effectively filling the content in the bag. SOLUTION: The bag has a front sheet 11 and a back sheet 12 opposing to it. At least one of the front sheet 11 and the back sheet 12 comprises an air permeable portion 11b or 12b made of an air permeable sheet like material and an impervious portion 11a or 12a made by laminating a resin layer on the part of the sheet like material. The content can be filled in the bag by a filling device having a suction transfer means sucking and holding the impervious portion 11a or 12a of the bag 10 and transferring it to the downward portion of the filling device, an opening broadening means broadening the opening 14 of the transferred bag 10 and a bag enlarging means inserted from the broadened opening 14 in the inner side of the bag 10 to outward push and enlarge the front sheet 11 and the back sheet 12.
