A woven laminated plastic bag having features that prevent leakage of contents out of the bag, or infestation of organisms into the contents of the bag is provided. The bag can provide a top end and a bottom end that provide a discrete area that may contain discrete graphics or printing. The bag can also include an easy open feature that can be easily opened with less force than a sealed closure of the bag. The easy open feature may be oriented in various directions with respect to the bag.

A thermoplastic bag includes duplicative seals. In particular, in one or more implementations, a thermoplastic bag includes a first seal and at least a second seal reinforcing the same area of the thermoplastic bag. For instance, in one or more implementations, the thermoplastic bag includes multiple seals along each side edge or along the hem. If one seal fails, the other seal(s) can remain in place to prevent leaks. Thus, the duplicative seals of the thermoplastic bag can provide reinforced strength and desired aesthetics.

Embodiments include a method of manufacturing a container with a leak resistant seal. The method includes forming an elastomer or a plastic or any combination thereof into a container inside out by forming an outside portion of the container on an internal surface of the container before inverting the container and forming an inside portion of the container on an external surface of the container before inverting the container. In embodiments, the method includes forming or coupling a leak resistant seal on the external surface of the container before inverting the container. The leak resistant seal provides access to the inside portion of the container when the leak resistant seal is open after inverting the container and holds at least liquid internal to the container when applying an external force to the container without use of an external structure to keep the leak resistant seal closed after inverting the container.

A package is provided that is formed from a packaging material, such as film, having increased adhesive in critical locations, such as adjacent folds in the end seal and other areas so that that the increased adhesive can at least partially fill voids adjacent such folds. The additional, localized sealant material is applied in a plurality of discrete locations in the end seal or other region adjacent where folds are formed and overlap with a sealant layer so as to provide additional sealant material for at least partially filling the voids without being present throughout the entirety, majority or large portions of the packaging material.

A container body of the sheet container is composed of a sheet member given by lamination of a plurality of film layers, and has a plurality of surface-like parts; the plurality of surface-like parts include a first surface-like part and a second surface-like part that adjoin and cross each other; the sheet member has a filler enclosing part in which a filler is enclosed between the plurality of film layers; the filler enclosing part includes an intermediate extending part laid across the first surface-like part and the second surface-like part, and a first adjoining part and a second adjoining part that individually adjoin both sides of the intermediate extending part; and the intermediate extending part extending more further from the second surface-like part than the first adjoining part and the second adjoining part extend.

Provided is a sheet for container to be used in a flexible container, the sheet for container having a plurality of films layered in the sheet for container, the sheet for container including: a first film including a first base-material layer, which is coated with a first applying-type gas barrier layer and made of a single type of material having a heat-sealing property; and a second film including a second base-material layer, which is coated with a second applying-type gas barrier layer and made of a single type of material that is a same type of material as the first base-material layer, in which: the first film and the second film are attached to each other by heat sealing; and a gas enclosing portion, which is partially non-attached and in which gas is able to be enclosed, is formed between the first film and the second film.

The invention is a bag (10) that has a handle (12) and a handle grip section (14) that are connected externally on the main body (11) to be used for carrying, it comprises a support handle (13) connected from the inner surface of the bag (10) on the main body (11) which is already connected to a handle (12) so as to increase the carrying load capacity and a handle grip section (14) formed on the support handle (13) so as to connect the support handle (13) to the main body (11).
