Valve bag with alignment means |
摘要 |
A valve bag and an interconnected series of valve bags is disclosed which have alignment means on the bag. This is shown as a continuous tunnel along a first edge of the interconnected bags for guidance into an automatic bag filling machine, for example, onto a mandrel threading the tunnel. Each bag has a valve formed by overlapping portions of panels of one wall of a bag. Parts of the overlapping portions are sealed together and other parts are left open between two valve side edge lines to form a valve from the overlapping material.
