ABSTRACT:
Bags having side panels and front and back panels -- such as laminated paper bags in which produce such as biscuits and cookies are sold -- may have closures attached to them so that the bag is closed and sealed with product inside for wholesale and retail sales, and may be opened and re-closed by the end purchaser. Where the closures comprise a pre-formed plastic closure having at least one open jaw into which the top of the bag, when shut, is inserted, and which are applied to a portion of the front panel of the bag. Apparatus is provided for applying the closure to the bag, which apparatus comprises means for applying the closure to the folded top of the bag which is intended to be inserted in the closure when in use, means for applying adhesive to the closure, and means for maintaining the closure and surface of the bag in contact one with the other while the adhesive between them becomes effective. The apparatus may include sufficient work stations to fold the panels of the bag with produce in it; and also plastic forming, cooling and cutting work stations for forming the individual closures from a strip or roll of suitable sheet plastic.
