Abstract:
The method of preparing bags for produce or the like, which comprises:advancing a solid-wall thermoplastic sheet and a mesh sheet, each having an upper edge, along a process line; folding a bottom portion of said plastic sheet upwardly to define a lower edge of said thermoplastic sheet at a fold line; sealing an upper end of the upwardly folded portion of said solid-wall thermoplastic sheet to a lower end of said mesh sheet while leaving the unfolded solid-wall sheet portion unsealed to form a solid wall header section extending away from said lower end of said mesh sheet; forming transverse slits in said sheets, and heat sealing the sheets together at edges of said slits to form separate bags between said slits, said slits extending across both sheet lower edges of the bag but being spaced from said upper edges; dropping produce between said sheet upper edges into said bags; and heat sealing said bags adjacent to the upper edges thereof.
