Hermetic seal for foil-lined fibc (bulk bag)

A bag configured to hold a volume of a material, comprising:

• an opening on the top side of the bag;
• an inner layer that is configured to provide an airtight enclosure for the material, wherein the airtight enclosure can be accessed via the opening;
• an outer layer that is positioned around the inner layer, wherein the outer layer provides structural support and integrity with a ribbon weave;
• the opening includes a neck formed by at least one of the inner layer or the outer layer;
• a collar having a top end and a bottom end opposite thereto, an internal wall that defines a through passage that extends between the top end and the bottom end, an external wall opposite the internal wall, and the collar having a thickness and a diameter for the through passage;
• the collar positioned over the neck and with at least one of the inner layer or the outer layer folded over a lip of the collar, wherein at least one of the inner layer or the outer layer are folded onto the external wall of the collar;
• and
• a lid that is releaseably coupled to the collar, the lid when attached to the collar applies a force to press the lid, the outer layer, the inner layer, and the lip of the collar together, wherein the lid comprises a sampling port and a removeable cap configured to:
• seal the sampling port when attached to the sampling port, and
• provide access to the material when removed from the sampling port, while the lid remains coupled to the collar.

A seal assembly system for a bulk bag, comprising:

• a bag that stores a material having a first end and a second end opposite thereto, the bag includes an opening at the first end;
• the bag includes an inner layer and an outer layer, wherein the inner layer is a foil laminate and the outer layer is a ribbon-woven structure made of polypropylene;
• a collar having a top end and a bottom end opposite thereto, an internal wall that defines a through passage that extends between the top end and the bottom end;
• the collar further includes an external wall;
• the collar having:
• a lip on the top end;
• a web that is perpendicular and outward from the external wall;
• and
• a support rib in between the lip and the web;
• the collar is affixed around a portion of the bag such that the outer layer is in contact with the internal wall and the external wall;
• a compression member that is configured to be positioned around the collar to compress the outer layer and the inner layer toward the external wall of the collar;
• and
• a lid having a top side with a first diameter, the lid is configured to releaseably attach to the lip of the collar to provide a hermetic seal at the opening, wherein the lip is in contact with the outer layer, the lid is in contact with the inner layer, and the lid couples to the lip with the outer layer and the inner layer in between, the lid comprises a sampling port having a second diameter that is less than the first diameter, and a removeable cap configured to:
• seal the sampling port when attached to the sampling port, and
• provide access to the material when removed from the sampling port, while the lid remains attached to the lip of the collar.
