The container bag includes lateral walls, the particulate materials filling an inner space defined by the lateral walls, a bottom wall formed generally in a quadrangle shape and connected to the bottom ends of the lateral walls, a cover connected to the top ends of the lateral walls, and hoops connected to the top ends of the lateral walls, the cover, the lateral walls and the bottom wall being formed from a flexible material, wherein each side of the quadrangle-shaped bottom wall is recessed at the central area thereof.

Abstract: A flexible, stackable container for storing a quantity of a product includes a sealed package that is formed from a single sheet of film having oppositely disposed lateral edges. The package includes a first panel and outwardly extending corner seals that border more than two sides of the first panel, a second panel disposed opposite the first panel and having an end seal, and four lateral sides disposed between the first and second panels. The second panel is formed by tucking portions of the lateral sides proximate the lateral edges inwardly and sealing portions of the film proximate the lateral edges together to form an end seal, the end seal being folded over towards an outer surface of the package.

Abstract: A bag has a reinforcement that is configured in a predetermined manner for reinforcing at least a portion of the bag. One or more predetermined areas of the bag may be reinforced. The bag may have one or more layers, and may be reinforced by placing and affixing reinforcing media in selected areas. The nature of the reinforcing media—its dimensions and structural properties—may be selected with respect to targeted uses of the bag. The bag may be subjected to one or more types of potentially failure-causing strain (e.g. bending, twisting, puncture, tensile, compression) during the useful life of the bag. For example, the bag may be stressed during filling the bag with product, top sealing, conveying by hand or machine, loading and stacking, transportation, storage, selling and final use by the consumer.

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.

Abstract: Methods of increasing the perceived thickness and strength of a thermoplastic film include incrementally stretching thermoplastic films in the machine direction.
