Abstract
The method includes the step of providing a cylindrical mandrel with vacuum openings around the circumference thereof and of a diameter substantially equal to the maximum diameter of the container. A thermoplastic strip is then wrapped around both the container and the mandrel, and just that portion of the strip enclosing the container is heat shrunk to follow closely the contour of the container. Then, the mandrel is withdrawn from the thermoplastic sleeve and that portion of the sleeve extending above the container is heat shrunk to engage snugly over the top of the container lid.
