Tubular casing container and manufacturing method for tubular casing container

A manufacturing method for forming a tubular casing container, the method comprising the steps of:

• printing a package design on an original fabric film and forming transparent no-print zones along both left and right end edges of the original fabric film;
• subsequent to the step of printing a package design, printing best before date characters on a surface of the no-print zone of the original fabric film with an inkjet method;
• subsequent to the step of printing best before date characters, circularly bending the original fabric film to place the no-print zone, on which the best before date characters are printed, on a lower side and the other no-print zone on an upper side to form a superimposed portion and to form a cylindrical casing portion;
• subsequent to the step of circularly bending the original fabric film, performing heat sealing of some of the superimposed portion to form a heat seal portion comprised of a portion with the best before date characters in the no-print zone located on the lower side, the heat seal portion extending up to an end edge of the no-print zone of the lower side and forming an upper side no-heat seal portion extending from the heat seal portion to an end edge side of the no-print zone located on the upper side;
• subsequent to the step of performing heat sealing, filling food in the cylindrical casing portion;
• subsequent to the step of filling food in the cylindrical casing portion, sealing both ends of the cylindrical casing portion with clips or by heat sealing to form sealed ends;
• and
• subsequent to the step of sealing both ends, cutting off outsides of the sealed ends.
