摘要 |
A reclosable bag having an open end with a side margin adjacent the open end, a metal segment in the side margin having ends extending beyond the opening and a sealing tape overlying the metal strip for encapsulation thereof. Apparatus for manufacturing reclosable bags includes a continuous webbing of flexible bags joined end-to-end, a continuous roll of metal strip with an arrangement for forming the metal strip into discrete segments. A roll of adhesively coated sealing tape and an arrangement for positioning the sealing tape over a metal strip segment while applying the sealing tape to one end of a flexible bag. A method of forming the reclosable bags includes the steps of providing a serial succession of bags joined end-to-end, stretching a portion of each bag so as to be free of wrinkles, aligning a metal strip segment with the wrinkle-free portion of the bag and sealing the metal strip segment of the bag with a portion of sealing tape. |
