Method of producing a reclosable bag |
摘要 |
A flexible closure strip capable of being bent manually and retaining the bent shape is interposed between the front ply and the back ply of a thermoplastic bag. The front and back plies are heat sealed to each other to form a pocket in which the stiffener strip is located and a bag mouth is formed under the heat seal.
