1. A method for forming a panel for a flexible package, the method comprising the steps of:
providing a first laminate from an unwinder of a first supply station, the first laminate having an inner face and an outer face;
forming an open area on the first laminate at a first cutting station;
providing a second laminate from an unwinder of a second supply station, the second laminate having opposing top and bottom edges and opposing side edges;
sealing at at least a first sealing station the second laminate to the inner face of the first laminate around the open area to cover/close the open area;
forming spaced apart slits in between the opposing side edges of the second laminate at a second cutting station to cause an area of the second laminate between the spaced apart slits to remain free as the second laminate remains sealed at the opposing top and bottom edges and to form a loop with the outer face of the first laminate;
providing a third laminate from an unwinder of a third supply station; and
sealing at a second sealing station the third laminate to the inner face of the first laminate around the open area, whereby the top and bottom edges of the second laminate are sandwiched between the first laminate and the third laminate.
