Problems solved by technology

[0028] In particular, the temperature of the packaging material at the cold zone 106 may not be high enough to provide proper melting of the layer of heat-sealable plastic material and thus insufficient to provide a proper seal.

Embodiment Construction

[0041] refer to figure 2 , shows a packaging machine 1 for continuously producing sealed packages 2 of food products from a web 3 of packaging material unrolled from a reel 4 and fed along a forming path P.

[0042] The packaging machine 1 preferably produces packages 2 of pourable food products, such as pasteurized or UHT milk, fruit juices, wine, peas, beans and the like.

[0043] The packaging machine 1 can also produce packages 2 of food products which are pourable when the package 2 is produced and which solidify after the package 2 has been sealed. An example of such a food product is a portion of cheese which is melted when the package 2 is produced and which solidifies after the package 2 has been sealed.

[0044] The packaging material has a multi-layer structure comprising essentially a base layer for stiffness and strength, which may consist of a layer of fibrous material (e.g., paper) or a layer of mineral-filled polypropylene material and a plurality of layers o...

Abstract

An induction heating sealing device (30) for sealing a packaging material comprises an electrically conductive layer and advancing, in use, along a first direction (A), said induction heating sealingdevice (30) comprising an inductive element (100), said inductive element (100) comprising a first leg (31) and a second leg (32) extending along said first direction (A) and within which, in use, analternate current flows, said first leg (31) having a first body (33) facing a second body (34) of said second leg (32) and at least one projection (35) laterally projecting from said first body (33)and facing, in use, an area (53) of said packaging material to be sealed and being configured to induce, in use, an eddy current within said area (53).

Description

technical field [0001] The present invention relates to an induction heat sealing device, in particular an induction heat sealing device for applying a sealing strip to a web of packaging material for producing sealed packages of pourable food products. Background technique [0002] It is well known that many food products such as juices, pasteurized or UHT (Ultra High Temperature Treated) milk, wine, tomato paste, etc. are sold in packages made of aseptic packaging materials. [0003] A typical example of this type of packaging is the parallelepiped-shaped packaging called Tetra Brik Aseptic (registered trademark) for liquid or pourable food products, which is made by folding and sealing a laminated web of packaging material. [0004] The packaging material has a multi-layer structure comprising essentially a base layer for stiffness and strength, which may consist of a layer of fibrous material (e.g., paper) or a layer of mineral-filled polypropylene material and a plurali...
