A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

The invention relates to an extrusion blow-molded container, the inside of which is defined by a container side wall and a container bottom, a standing area being detachably connected to the container side wall and to the container bottom. According to the invention, at least a subarea of a bottom of a primary container product formed from the parison is irreversibly moved into the container such that an undercut container bottom is embodied on the container at least in a subarea, the standing area of the container being formed in the region of the undercut container bottom from a side wall of the primary container product by bending and/or pressing down.

The invention provides a thermoplastic film comprising: a base film wherein the base film comprises a stretchable polyolefin material comprising one or more layers; and a plurality of extruded fiber elements; wherein the extruded fiber elements are located on at least one surface of the base film; wherein the extruded fibers form one or more protrusions relative to the plane of the base film; wherein at the location where the fiber elements are provided on the base film, a domain of a material mixture comprising the base film material and the fiber material is present between a domain of pure base film material and a domain of pure fiber material, and wherein the average thickness of the base film is less than the average thickness of the protrusion.

A process and apparatus (1) for packaging a product (P) arranged on a tray (4) is disclosed. The apparatus comprises a packaging assembly (8) configured for tightly fixing one or more film sheets to one or more trays. The packaging assembly includes a lower tool (22) defining a prefixed number of seats (23) for receiving the trays and an upper tool (21) facing the lower tool and cooperating with the upper tool to define a packaging chamber (24). The packaging assembly (8) is configured to operate at least in a first operating condition, where said packaging chamber (24) is open, and in a second operating condition, where said packaging chamber (24) is hermetically closed. First injection apertures (90) are positioned in corner regions of the seat and are configured to inject streams of gas in a direction substantially parallel to and above the flange (4c) of a tray (4) positioned in said seat. The process includes the step of activating injection of a plurality of streams of gas through said first apertures (90) in order to form a controlled atmosphere inside the tray before closing the tray with the film.

Superhydrophobic films from plastic waste and a fabrication method thereof are provided. Superhydrophobic films with variable thickness, comprising a base and top layer, can be created using semi-crystalline polymers, including virgin, recycled, or waste forms. The fabrication process utilizes 60% of total plastic waste, resulting in films with contact angles between 120? to 160?, tensile strength ranging from 1 MPa to about 70 MPa, and thickness ranging from 20 ?m to about 5 mm. Superhydrophobic films may impart protective water-repellent properties against the elements.
