<p>A method of the invention enables the production of a tubular package open at both ends and comprising a double- or multi-layered film. The film layers can be of one and the same or different materials. A package is formed around a mould (10), which is easily replaceable and determines the eventual size of the package (29). The method, which can be automated, includes producing the package (29), wrapping an article (25) and placing the article (25) in the package (29). The sections of said mould (10) are withdrawn from the package and the space in between the layered film is filled (23, 24) with air or some other gas, whereby the article attaches to the package.</p> |
