The pour spout is heat sealed to the package.

After the bioresorbable tube is selectably loaded, the bioresorbable tube is heat sealed at a sealing position adjacent a proximal most element.

The frame is then heat- welded to the underlying membrane around the perimeter of the photovoltaic module.

The welded assembly is hot rolled to provide a hot rolled band, and the material within the margin inhibits the cladding material from spreading beyond the edge of the substrate material during the hot rolling.

A seam that is heat soldered according to the present invention continuously extends across two-dimensional contours of significant widths.

The lid can be additionally heat-sealed to the upper surface (10) of the rim flange, so that two sealing lines (15) will be formed inside each other in the package.

Then, a spout is inserted in the hole and the spout is heat-sealed to the second body material (2) by a spout-sealing device (17).

Zirotti says: “We needed flooring that could be hot-welded to provide an impervious surface.

This invention has a first film provided with a flat portion (14b), and a bulging portion (14a) for holding a rod type body; and a second film heat sealed on the first film.
