Embodiment Construction

[0025] Reference 1 generally designates a packaging plant for producing sealed packages 2 of pourable food products, in particular sterilized and / or aseptically processed pourable food products, from tubes 3 of webs 4 of packaging material , such as pasteurized milk or fruit juice. In particular, in use, the tube 3 extends along a longitudinal axis L (in particular an axis L having a vertical orientation).

[0026] The web 4 of packaging material has a multilayer structure (not shown) and comprises at least one layer of fibrous material, such as paper or cardboard, and at least two heat-sealable plastic materials with the layer of fibrous material interposed between each other. (e.g. polyethylene) layer. One of the two layers of heat-sealable plastic material defines the inner surface of the package 2 which is ultimately in contact with the pourable product.

[0027] Preferably, but not necessarily, the web 4 also comprises a layer of gas and light barrier material, such as ...

Abstract

There is described a packaging apparatus (1) for forming a plurality of sealed packages (2) from a tube (3) of a web of packaging material (4) which is continuously filled with a pourable product. The packaging apparatus comprises an isolation chamber (10) separating an inner environment (11) containing a sterile gas from an outer environment (12). The packaging apparatus further comprises a delimiting element (48) arranged, in use, within the tube (3) and being designed to divide the tube (3), in use, into a first space (49) and a second space (50). The packaging apparatus (1) also comprises a pressurizing device (47) for pressurizing the second space (50) by means of a pressurized sterile gas. The delimiting element (48) is arranged within the isolation chamber (10).

Description

technical field [0001] The present invention relates to a packaging machine for forming sealed packages, in particular sealed packages filled with pourable products. Background technique [0002] It is known that many liquid or pourable food products, such as fruit juices, UHT (Ultra High Temperature Treated) milk, wine, tomato sauce, etc., are sold in packages made of aseptic packaging materials. [0003] A typical example is a parallelepiped-shaped package for liquid or pourable food products called Tetra Brik Aseptic (registered trademark), which is made by sealing and folding laminated strip-like packaging materials . The packaging material has a multilayer structure comprising a base layer, for example of paper, covered on both sides with a layer of heat-sealable plastic material, such as polyethylene. In the case of aseptic packaging for long-term storage products such as UHT milk, the packaging material also includes a layer of oxygen barrier material, such as alumi...
