A plastic film bag (B) having a tie element (62') coated on its inner surface with an adhesive (358) between the dotted line (356) and its outer end (354). The adhesive is completely covered by a removable release strip (360). The inner end portion (62a') is permanently attached to the bag by means of a heat seal (362) or a permanent adhesive. The tie element is made by applying multiple, parallel bands of adhesive to stock material, covering the adhesive with cover strips, and separating the web into individual rolls of web stock. Tie elements are applied to bags by moving tie element web stock along a path above a web of bag material, cutting the stock into individual elements, momentarily stopping portions of the bag material under successive tie elements, and firmly anchoring each tie element to its respective bag. |
