摘要:
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).

The invention provides for a slider for a leak proof slider-zipper assembly having a leading edge and a trailing edge comprising a pair of protrusions at the bottom of the leading edge, a pair of protrusions at the bottom of the trailing edge, and an opening plow protruding from the top surface of the slider, between the leading edge and trailing edge, and having height not more than the height of the slider. The opening plow has a sloping surface from the leading edge towards the trailing edge such that the height of the opening plow at the leading edge is less than the height of the opening plow at the trailing edge.
摘要:
A tamper evident diaphragm (110) for a flexible package (300) is provided. The tamper evident diaphragm (110) includes two diaphragm strips (112, 116). Each of the diaphragm strips (112, 116) includes at least an outer layer (140) and an inner layer (136) laminated with each other. The inner layer (136) of each of the diaphragm strips (112, 116) is sealable together to form a non-resealable peelable sealed band (142). The outer layer (140) and the inner layer (136) are configured to be sealed with the flaps (120, 124) of a zipper (108) of the flexible package (300).
