ABSTRACT:
A process for wrapping articles and providing a reclosable plastic container is disclosed. A plastic sheet is conveyed in a feed direction and a stiff closure member is aligned with the plastic sheet substantially parallel to the feed direction. The article to be wrapped is fed into the plastic sheet and one side of the plastic sheet is folded over the article and alongside the closure member. The other side of the plastic sheet is folded alongside the closure member in the opposite direction so that portions of the plastic sheet alongside the closure member face each other. Portions of the platic sheet facing each other on opposite sides of the closure member are heat sealed so as to enclose the closure member within heat sealed portions of the plastic sheet. The overfolded plastic sheet is heat sealed and cut transversely to form the container.
