Each extending heat-sealed side portion 19 can be formed. Therefore, the sides of the overlapping material layers at the bottom of the bag along the edges are sealed. In the flat form of the bag 3 (eg, FIG. 3), the outer creases 155 form the bottom edge of the bag. If desired, a filling line 158 (FIG. 2) may be printed or otherwise formed on the side of the web portion 150 to indicate a recommended stop point for a product (eg, water) that can be injected into the bag 3. it can. The web portion 150 and / or the bag 3 may have a different shape, configuration, and / or form without departing from the present disclosure.

In one embodiment, the reinforced package 1 can be formed by a packaging system in which the material webs forming the bag 3 are attached to the respective blanks 10, and the blanks and webs move through the respective packaging systems. The various parts and components of the system form separate packages. In another embodiment, the enhanced package 1 is formed by a system and method similar to that set forth in US Provisional Patent Application No. 62 / 231,723, which is part of this specification by reference. The bag 3 can be attached to each blank 10 after being formed at least partially, and the blanks and webs move through their respective packaging systems, depending on the various parts and components of the system. It can be formed into individual packages. The reinforced package 1 can be formed differently without departing from the present disclosure.

In one embodiment, the material forming the bag 3 can include preprinted paper, polyethylene, or other materials, including flexible and heat sealable materials. The sealed side portion 19 of each bag 3 is formed by joining the overlapping edge portions 119 of the material web 150 (for example, heat-sealing with a rotary heat sealer or the like). The bag 3 can be attached to each blank 10 with glue. For example, the bag 3 can be attached to the front panel 21 of the blank 3 in the glue strip G1. The bag 3 can be formed differently and / or attached to the blank 10 without departing from the present disclosure.
