A multi-layer film includes a skin layer, a core layer, and a seal layer. The multi-layer film may be used as a closure for a food container.

There is provided a container or an equipment having low-protein adsorption properties, to be used for administering, storing, conveying or transporting protein or a composition including protein, or for producing protein or a composition including protein. A container or an equipment for producing protein or a composition including protein, wherein the surface of the container or the equipment in contact with protein or a composition including protein is formed of a fluororesin which is at least one fluororesin selected from a tetrafluoroethylene-hexafluoropropylene-based copolymer and a tetrafluoroethylene-perfluoroalkylvinyl ether-based copolymer, which has a melting point of 320 C. or less and which has a total number of non-fluorinated group terminals and CF.sub.2H group terminals in the fluororesin of 70 or less per 110.sup.6 carbon atoms, has remarkable low-protein adsorption properties. Such a container or equipment can be used to thereby, for example, prevent, in a producing (culturing and purifying, and the like) step, a storing and delivering step and/or administration of a protein formulation such as an antibody pharmaceutical product, the protein formulation from being lost due to adsorption thereof to the equipment.

A propylene polymer satisfying (a) below, a soft propylene copolymer satisfying (b) below, and a polyolefin containing a structural unit derived from an unsaturated carboxylic acid and/or a derivative thereof, wherein (a) a melting point is 100 C. or more, and (b) an MFR is in the range of 0.01 to 100 g/10 min, at least one of the following requirements (b-1) and (b-2) is satisfied: (b-1) a syndiotactic triad fraction s 60% or more, and (b-2) a structural unit derived from propylene is 55 to 90 mol % and a structural unit derived from at least one olefin having 2 to 20 carbon atoms (excluding propylene) is contained at 10 to 45 mol % (with provisos), and the relation between an intrinsic viscosity [] (dL/g) and the MFR satisfies the relation: 1.50MFR.sup.0.20[]2.65MFR.sup.0.20.

A container including a containment wall, defining an internal containment volume and including a free edge, a closing element including a welding layer welded onto the free edge of the wall and a front layer defining an outer surface of the container. An intermediate layer of removable self-adhesive is spread onto an adhesion portion of mutually coupled surfaces of the welding layer and front layer. An opening line adapted to define an access window is obtained through an incision in a stretch of thickness of the welding layer splitting the welding layer into a welding portion adapted to be welded to the container and an opening portion corresponding to the access window, with reference to an assembled configuration on the container. The incision is made to allow the detachment of the opening portion from the welding portion while the closing element is opened.

A foam-based expansion joint seal system packaging which facilitates transport and reduces the need for internal splices.

Flexible packaging materials with electrophotographically printed images or information, and processes for preparing such flexible packaging materials are disclosed.

Aerator device for introducing gas bubbles into a liquid and comprising a base member with a gas supply and an elastic perforated membrane attached to the base member, and further with a UV protecting cover member, said UV protecting cover member or at least a part thereof being arranged above the membrane to protect the membrane against UV radiation during shipping and storage.

The present invention concerns a device (1) for applying gripping handles (M) on films (P), being supplied on shrinkwrap packers (2) for making bundles of bottles (B), cans and/or similar containers (B). The device (1) comprises: an applying head (10) provided with a roller (11) for applying gripping handles (M); an abutment mechanism (14) for operatively supporting a series of heat-shrinkable packaging films (P), being supplied on a respective shrinkwrap packer (2). The applying roller (11) and the abutment mechanism (14) are mobile with respect to one another between a non-operating condition, in which they are spaced apart, and an operating condition, in which the applying roller (11) is arranged, at the abutment mechanism (14), against at least one of the films (P) being supplied to apply a respective gripping handle (M) on the latter. The abutment mechanism (14) comprises a supporting tape (15) having an advancement surface (16) for advancing the films (P), which, in the operating condition, provides an abutment for the applying roller (11), which applies each handle (M) on a respective packaging film (P), acting against the advancement surface (16) of the supporting tape (15).
