Abstract (en)
[origin: WO9962768A1] A method and apparatus for forming a tamper resistant seal on a plastic bag containing a loaf of bread or other products is disclosed. The neck (125) of the bag (125b) is flattened, gripped between a pair of upper inboard and outboard gathering belts and a pair of lower inboard and outboard gathering belts adjacent opposite sides of a segment of the neck of the bag. A row of perforations(132) is formed in the bag neck as the bag moves adjacent a roller provided with teeth or cutting elements. Heated air jets are directed to engage the segment of the bag bridging between the inboard and the outboard gathering belts for fusing panels of the bag together to form a sealed strip spaced from the row of perforations in the bag neck to facilitate removal of the sealed strip from the bag.
