<p>The barrier has a plastic rail (2) that is made of thermoplastic material and/or plastic material, where the plastic rail is formed as a closed foil ring by overlapping an end (6) of the rail with another end (8) of the rail. A continuous weld seam (10) effects a connection for the foil ring or a continuous seam produces a chemical connection for the foil ring at an overlapping region (4). The thermoplastic material and/or plastic material for the rail is selected from the group of high density polyethylene, low density polyethylene, and linear low density polyethylene. An independent claim is also included for a package with a root barrier.</p> |
