Apparatus and method for making a reclosable bag

摘要

A storage bag (100) and a method and apparatus for forming such a storage bag. The storage bag contains a reclosure tie (101) formed as an integral marginal portion (between 101 and 104) of the bag beyond an edge of the bag. The marginal portion includes overlying layers (111, 112) of bag material that form an elongated structure along an axis with first and second ends (113, 114). A fused closure (116, 117) is formed in the marginal portion parallel to the axis and over a portion of the marginal portion spaced from one end thereof. This structure defines a tail (120) and open loop (121) that wrap around an opened bag (100) thereby to close the bag in a positive fashion.
