Abstract
A liner bag for, for example, a flexible intermediate bulk container (FIBC) includes a body portion formed by at least two sheets. The body portion has a first end and a second end defining a cavity therebetween. The first end has an opening for receiving a product. The liner bag also includes at least one seal (e.g., a vertical seal) joining the two sheets. The liner bag further includes at least one polymer flange secured to the two sheets and extending outward from the vertical seal to provide at least one fastening location to secure the liner bag to the container.
Claims16
A liner bag for a container, comprising:
- a body portion formed by at least two sheets, the body portion having a first end and a second end defining a cavity therebetween, the first end having an opening for receiving a product;
- at least one vertical seal joining the at least two sheets;
- and
- at least one polymer flange secured to the at least two sheets and extending outward from the at least one vertical seal to provide at least one fastening location to secure the liner bag to the container, wherein the at least one polymer flange is integral to at least one sheet of the at least two sheets,
- wherein each of the at least two sheets is a foil laminate sheet which includes a foil element and a polymer element, and
- wherein a portion of the polymer element extends beyond an edge of the foil element to create a polymer flange of the at least one polymer flange.
A method for creating and securing a liner bag to a container, comprising:
- joining at least two sheets of foil laminate to form a liner bag for a container, wherein each of the at least two sheets of foil laminate are comprised of a foil element and a polymer element, the at least two sheets of foil laminate having at least one polymer flange extending outward from the at least two sheets of foil laminate, wherein the at least one polymer flange is integral to at least one sheet of the at least two sheets;
- forming the at least one polymer flange by extending a portion of the polymer element beyond an edge of the foil element;
- and
- sewing the liner bag to the container through the at least one polymer flange.
