Benefits of technology

[0017]It is preferred that the bag has side gussets provided between the front panel and the back panel. The side gussets are usually formed by two additional film panels that are fixed

Problems solved by technology

It is one key disadvantage of the known film bag that it cannot be emptied easily.
Furthermore, the known bag forms a straight opening which is difficult to handle.
The edges of this straight opening have to be separated in a way that is cumbersome, especially with a bulging bag.

Embodiment Construction

[0026]As seen in FIG. 1 a film bag 1 according to the invention has a front panel 2 with a front face 3 and a geometrically similar opposite back panel 22 with a back face and only shown partially in FIG. 2. The front panel 2 and back panel 22 are joined directly by parallel top bottom welds 4 and 5. Side gussets with fold lines 6 shown by a dashed line are folded between side edges of the panels 3 and 22 and secured thereto by side or longitudinal welds 7.

[0027]According to the invention, a rectangular inner cover patch 8 is connected to an inner face 9 of the front panel 3 by a continuous rectangular frame weld 10. The frame weld 10 is formed thermally.

[0028]A flap 11 is formed by a cut line 12 and two adjoining weakening lines 13 in the material of the front panel 2 surrounded by the frame weld 10. The full cut 12 defines a grip tab 14 of the flap 11 whereas the rest of the flap 11 is defined by the weakening lines 13 formed by rows of perforations. The ends of the weakening lines 1

Abstract

A film bag has a front and back panel and an inner cover patch therebetween. A continuous frame weld secures the inner cover patch to the inner face of the front panel. A first cut or weakening line in the front panel within an area bounded by the frame weld defines all but one side of a flap hinged at the one side to the front panel. A reclosable fastener is between the front face of the patch and the inner face of front panel, and a direct attachment between the fastener and the hinge is between the front face of the flap to the inner face of the front panel. A second cut or weakening line is formed in the inner cover patch between the direct attachment to the flap and the recloseable fastener.
