Thermoplastic bags with phased deformation patterns are described. In particular, one or more implementations comprise thermoplastic bags with ring rolling, SELFing, or other deformation patterns phased or aligned relative to the sides of the bags. The phased deformation patterns can allow for reducing or eliminating deformation patterns in areas of the thermoplastic bag in which side seals or other seals are formed. Additionally or alternatively, the phased deformation patterns can provide for zones that provide differing properties (e.g., functional or aesthetic). Such zones can vary aligned along a width of the thermoplastic bag and optionally also vary along a height of the thermoplastic bag. The differing zones can provide the thermoplastic bags with phased deformations that provide leak prevention, liquid containment, and other benefits.

A plastic film bottom bag has a plastic film front wall that is welded or adhesively joined to side wall sections of adjoining plastic film side walls, and/or a plastic film rear wall that is welded or adhesively joined to the side wall sections of the adjoining plastic film side walls, so as to form a seam or casing seam. Further disclosed is a plastic film bottom bag, in which at least one, in particular both, plastic film side walls are provided with a side fold that comprises a welded or adhesive joint extending from or at a distance from the bag opening edge in the direction of the bag end or up to the bag end. The disclosure further relates to blanks for the plastic film bottom bags described herein and to the use of the plastic film bottom bags described herein, as reusable bags or reusable handbags.

A flexible structure may be configured to expand a collapsible flask. The flexible structure may include a first loop made of an elastically flexible material and a second loop made of an elastically flexible material. The first loop and the second loop may be operatively coupled together at a first intersection and a second intersection. The first loop and the second loop, together, may be elastically movable between a compressed configuration in which the first loop and the second loop are sufficiently narrow to fit through an opening of the collapsible flask, and an expanded configuration in which the first loop and the second loop are not sufficiently narrow to fit through the opening.

A reinforced polybag and methods of manufacturing the same are presented. A method of making a reinforced polybag involves: providing a plurality of walls; providing a hole in a wall of the plurality of walls such that a remaining portion of the wall separates the hole in the wall form a side edge of at least one side edge of the wall; forming the polybag out of the plurality of walls by attaching each wall in the plurality of walls along the at least one side edge of that wall to at least one adjoining wall; providing a synthetic resin fiber mesh cover to cover the hole in the wall; and attaching a peripheral portion of the synthetic resin fiber mesh cover the remaining portion to cover the hole in the wall. Each wall in the plurality of walls is made of a synthetic resin film.

In a container for packaging filling materials, in particular a bag or pouch made of plastic film, comprising at least one container wall surrounding the filling material, which has at least one front and rear wall, and comprising superposed layers formed in the top region of the container, wherein in the top region of the container predetermined layers are connected over at least one section by means of at least one closure means closing the container, below which a section of the top region located adjacent to the region fitted with the opening has a filling material withdrawal region and that at least one section of a connecting seam is disposed so that it runs around an opening at least in some areas in such a manner that in the top region the multilayer region is separated in a sealing manner from the filling space of the container.
