  • Patent number: 8550717
    Abstract: A composite or so-called “half and half” bag has a first side wall formed from a synthetic resin mesh material and a second side formed from a synthetic resin film material. A reinforcing strip extends horizontally along the upper end portion of the mesh side wall of the bag. The reinforcing strip overlaps the upper edge of the first side wall such that it is joined to the first side wall through a horizontal seam positioned well beneath the top edge of the reinforcing strip to form an extension that protrudes well above (e.g., ½ inch to 1½ inches or even more) the upper edge of the mesh side wall. In order to strengthen the seam at the sides of the bag, the side edges of the reinforcing strip are joined to the second film side wall along at least most of the vertical extent of the extension. This film-to-film bond is considerably stronger than a bond through an intermediate mesh layer, as occurs along the remainder of the side seams of the bag.

  • Patent number: 7837388
    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.
