A method for sealing an open end of a multi-layer sheet comprising:
- providing a multi-layer sheet;
- providing a sealing tape, the width of said sealing tape is equal to or larger than the thickness of said multi-layer sheet, wherein the sealing tape is made from a thermo-plastic material;
- thermo-plastically adhering said sealing tape into said open end of said multi-layer sheet by at least heating said sealing tape to a temperature above the Glass transition temperature of the sealing tape's material, so as to submerge said sealing tape into said open end of sub-spaces in said multi-wall sheet, wherein thermo-plastically adhering said sealing tape into said open end results in sealing of said open end;
- and
- removing protruding edges of said sealing tape when said edges are protruding from said open end.
