Abstract
The system uses a shrink film covering all the products (12) arranged inside a cardboard box (1) and holding these products against one another and also against the base (2) of the box. At least two heat-shrinkable sheets (9, 10) are attached, by one of their edges, in the region of the join between the base (2) of the box and the sides (4) of the lateral band (3) of this box. An additional heat-shrinkable sheet (14), supplied at the upper level of the lateral band (3) or of the products (12), is joined by welding to the previous sheets (9, 10) in order to form a single film that is shrunk over the products (12). A heat-protection sheet (13) may be inserted between this film and the products (12). The invention applies to packaging for the preparation and dispatch of product orders.
