The present invention provides a method of making re-closable package (10) and a product made therefrom. The said method comprises providing a first web (46) and a second web (50), folding a predetermined portion (P) of the first web (46) into a V-shape (58) thereby forming an extended portion and cutting the V-shape (58) of the first web (46) to form a pair of extended panels (62). A re-closable zipper (42) sealed with the extended panels (62). The first web (46) sealed with the second web (50) at a first sealing zone (SZ1) and second sealing zone (SZ2). Subsequently, cut the first web (46) and the second web (50) at the first sealing zone (SZ1) thereby obtaining a re-closable package (10).

An easy-open/reclosable gusseted package includes a reclosure mechanism including a first and second interlocking strip; a die cut in a first panel and in a first and optionally a second gusset. The die cut defines a die cut segment spaced from the first and second ends of the package that can be displaced to open the package and access a contained product between the interlocking strips, the interlocking surfaces being at least partially exposed. The package can be reclosed, after removing the die cut segment, by engaging the interlocking surface of a second portion of the first interlocking strip with itself in the first gusset, and optionally a third portion of the first interlocking strip with itself in the second gusset, folding the package, and engaging the interlocking surface of the second interlocking strip with the interlocking surface of the first portion of the first interlocking strip.

Flexible reclosable enclosure with flap

A reclosable enclosure includes a body having a front panel and a back panel secured to each other and forming a cavity therebetween to store contents. The body includes a flap that extends from a top end of the body. The reclosable enclosure includes a zipper assembly coupled to an interior surface of at least the front panel. The zipper assembly includes a first profile strip and a second profile strip that form a reclosable zipper to selectively close the cavity. The flap blocks access to the reclosable zipper and is sealed to at least one of the front panel or the second profile strip in an intact state of the flap. The flap defines one or more lines of weakness to permit irreparable separation of a sub-flap from a remainder of the flap to access the reclosable zipper.
