Abstract
A multi-substrate sheet for forming an at least partially open mesh fabric bag using a form, fill and seal machine and a bag formed of this sheet are provided. The sheet includes at least one strip formed of an open mesh polymeric fabric and at least one strip formed of a polymeric film. The fabric and film strips are secured to one another to form a web that can be formed into a roll and utilized with a form, fill and seal machine. The bag resulting from the processing of the web by the machine includes a substantial open mesh fabric portion to provide adequate ventilation to the product positioned within the bag and a printable film portion.
