Method of forming assembled package with first package face and second package face

A method of forming an assembled package, comprising:

• providing a sheet of material in the form of a strip;
• fixing a first end portion and a second end portion of the sheet of material to each other to form a sealing flap, a remainder of the sheet of material remaining connected to the sealing flap;
• first folding the remainder of the sheet of material onto itself to form a first package face and a second package face that oppose each other, the sealing flap extending from the first package face;
• sealing the sheet of material along opposed longitudinal edges of the sheet of material;
• first defining an opening cut in the sealing flap, the opening cut being defined by both the first end portion and the second end portion;
• and
• connecting the sealing flap to the first package face to form the assembled package, the opening cut not being visible or directly accessible on the assembled package.
