Abstract: The present invention provides a method of packaging one or more articles, comprising the steps of: a) placing a first sleeve (11) of heat-shrinkable material in place on the article to be packaged; b) A thermal process is used to shrink the first sleeve (11) onto the article; c) The second sleeve (12) of heat-shrinkable plastic material is placed on the first sleeve (11) already covered by the shrinkage (11) ) on the article; and d) using a thermal process to heat the wall of the collapsed first sleeve (11) so as to obtain thermal equilibrium with the wall of the second sleeve (12) placed in place, and then The second sleeve is retracted onto the first sleeve. The present invention also provides a wrapper for packaging one or more articles, the wrapper comprising a sleeve of two overlapping heat-shrinkable plastic materials.
Sovereign Items: 1. A method of packaging one or more items, characterized in that it includes the following steps: a) Placing a first sleeve (11) of heat-shrinkable material on the item to be packaged In place; b) using a thermal process to shrink the first sleeve (11) onto the article; c) placing the second sleeve (12) of heat-shrinkable plastic material over the already covered shrinkage An item in the sleeve (11); and d) using a thermal process to heat the wall of the collapsed first sleeve (11) so as to obtain thermal equilibrium with the wall of the second sleeve (12) placed in place, The second sleeve is then retracted onto the first sleeve.
