A. method (100) of making an integrated handle (304) on at least one side gusset (308) of a flexible package (300) is provided. The method (100) includes steps of sealing a handle patch (222) on at least one half width of the side gusset laminate (218). Further, the method (100) provides parallel openings on the handle patch (222) such that a centre line of the two parallel openings coincides with centre lines of each half of the side gusset laminate (218). A cover patch (226) is sealed over the handle patch (222) overlapping the edges of the handle patch (222) and simultaneously with the side gusset laminate (218) all around, such that a predefined area is left unsealed between the two parallel openings. The longitudinal edges of the side gusset laminate (218) are folded such that the handle patch (222) comes on the outer surface of the continuous open tube (242) being formed. The continuous open tube (242) is thereby used for manufacturing the flexible package (300). Reference Figure 1 |
