Multilayer skirt of a flexible tube, comprising an extruded main layer () and a mono- or multilayer film () at least partially surrounding the main layer. The tensile modulus of the main layer is less than 1200 N/mmand the tensile modulus of the film is greater than 3500 N/mm.

Multilayer plastic tube structure

The invention relates to an essentially tubular flexible packaging intended for containing a semi-liquid or pasty product, which includes an apron, a head, an added piece of material at least on the inside of the apron, and optionally a lid, the apron consists of a rolled-up sheet and includes a longitudinal weld for assembling the edges thereof together, and the head being attached to the edge of one of the ends of the apron. The apron includes a ratio of at least 30% of recycled material or material from renewable resources, and the added piece of material is arranged so as to eliminate a discontinuity in the inner surface in the area of the longitudinal weld.

Flexible packaging manufactured by welding and containing a material that is recycled or from renewable resources

Packaging produced from a thermoplastic film of which the ends are placed so that they abut, said film being composed of several layers, including at least a first weldable layer and a second layer of which the butt-welding is only partial or non-existent, and at least one thin strip covering said ends and being directly attached to one of the faces of the second layer, the difference in the melting point between the first layer and the other layer or layers being greater than 20&#xb0; C.

Packaging formed from a butt-welded film

The invention relates to a flexible packaging tube formed from a laminate comprising at least one first layer and one second layer, characterized in that the first layer is formed from a material whose properties make it possible to weld the first layer to itself and in that the second layer is formed from a material whose properties make it impossible to weld the second layer onto the first layer.

Flexible multilayer structure for tubes

Process of hot-filling a plastic container comprising a side wall connected to a neck and to a base, with a liquid or viscous product; process consisting in at least filling the container with a product at high temperature, hermetically sealing the container, cooling the container and its contents; process characterized in that a plastic container is used for which the linear thermal expansion coefficient of the side wall is greater than 0.00014 m/(m.K) and in that the container is allowed to expand and shrink at least as much as its contents.

Plastic bottle for hot filling or heat treatment

The invention relates to a rigid or semirigid plastic part designed to form the bottom of a package whose side wall consists of a laminated film. The plastic part has a central axis and includes the following features: a peripheral welding zone designed to contact and be welded to the inside surface of the side wall; a convex inside face and a concave outside face; the inside face and the outside face each comprise a zone whose centre is on the axis and which is designed to contact a tool used to attach the part to the side wall; and a profile at least partially defined by a curve. The invention also relates to a package having a bottom consisting of the plastic part.

Plastic bottom for package

Container with an opening and closing element () for wine or a similar beverage, comprising three distinct elements (-) made of plastic and assembled by welding, these being a flexible laminate () that forms the side wall of the said container, an end wall () and a shoulder () comprising a neck; characterized in that at least one of the three elements (-) is oxygen impermeable and in that at least one other element (-) is oxygen permeable.
