摘要：The present invention provides an improved method and apparatus for
production of open mesh bags. The method and apparatus produces heat-sealable seambag stock for making individual bags having a closed end formed by folding the fabric, anopen end capable of being sealed and longitudinal, improved strength heat-sealed sideseams containing strips of heat-sealable material extending from the closed end to theopen end. The process for making open mesh bags comprises the steps of applying to anopen mesh substrate (18, 20) a print band material bearing a readable indicator andapplying to the substrate at selected positions strips (26, 36) of a thermoplastic resin towhich the substrate is heat sealable, wherein the positions of the strips are selectedbased on the indicators on the print band material.
