Description

WO 2014/064308 PCT/ES2013/070588 On other occasions, bags are produced from a continuous laminated sheet, Which closes upon itself to arrive at the aforementioned tubular body, through a longitudinal line of heat-sealing, after Which the aforementioned process is repeated, in such a manner that as the bags are filled, they are simultaneously separated to become a single unit.
The best solution to date belongs to the same applicant as this invention and consists of a laminated sheet of plastic into Which a series of openings are made Which are closed by a reticular material attached to the sheet by means of heat-sealing or similar process.
Description of the invention The continuous band proposed in the present invention, constitutes of a technological advance in this field and is based on the use of a single continuous plastic-coated sheet, coinciding in width With the sheet itself such that the said sheet is designed to close over upon itself, by means of heat-sealing its longitudinal seam, in order to configure a continuous tube that can be fragmented in multiple areas corresponding to respective bags, the said continuous band having one or more Windows and, Where appropriate, perforations of the same or different sizes that can be closed With the aid of a mesh fragment, formal and dimensionally suitable for each Window and fixed to the periphery of the same. The continuous band is formed from a continuous sheet plastic-coated on at least one of its sides, having the same width as the said continuous sheet; continuous sheet of plastic-coated paper to Which, in correspondence With each one of the sectors intended to produce a bag, polythene reinforcements are provided in the areas envisaged for the handles, the heat seals and the edges or periphery of the Windows, and, Where appropriate, perforations, attached to the plastic-coated sheet by means of heat-sealing or similar procedure.
WO 2014/064308 PCT/ES2013/070588 In a first embodiment of the invention in correspondence With each one of the areas of continuous sheet of plastic-coated paper at least one Window is created, Which closes With the aid of a fragment of mesh, formal and dimensionally suitable for the said Window and fixed by means of a heat seal at the periphery of said Window.
The sheet of plastic-coated paper can be plasticised on both sides.
In a second embodiment of the invention When in each section of the continuous sheet of plastic- coated paper a sole Window is created With its corresponding mesh, the said Window is centred With respect to the longitudinal axis of the continuous sheet of plastic-coated paper, and to both sides of the sheet small perforations are established, Without mesh.
There is an option that the mesh Which closes the Window to be a continuous strip of mesh which runs longitudinally along the continuous sheet of plastic.
In any event, over and above the polythene reinforcements available in the handle areas, one can also have a secondary polythene reinforcement fixed to the polythene reinforcements by means of heat-sealing or any other method, With the special feature that the second reinforcement is fixed to the polythene reinforcement on the surface of the latter unrelated to a “U”-shaped strip delimited by a punched line that affects both the polythene reinforcement and the sheet of plastic-coated paper, a strip Which constitutes a handle designed to emerge through the opening ofthe bag body.
The punched lines deterrninant of the “U”-shaped strip Which can be pre-cut or sliding, retain the said strip in coplanar disposition With the rest of the polythene reinforcement and the plastic- coated sheet.
Moreover, each sector of the band designed to produce one bag incorporates polythene reinforcements corresponding With two points at the opening of the bag With are diametrically opposed to each other, so that the base incorporates two handles Which emerge from the opening of the bag Which are also diagonally opposite.
WO 2014/064308 PCT/ES2013/070588 With the continuous band of plastic-coated paper previously described, we obtain a product with all the advantages of the continuous plastic-coated bands but at a reduced cost and with the possibility to recycle some of the materials utilised in its manufacture therefor causing less harm to the environment.
Description of the Diagrams Figure l: shows the sheet of plastic-coated paper with the polythene reinforcements attached.
Figure 2: shows an exploded view of the sheet with the windows, punched perforations, mesh fragments and handles.
Figure 3: shows the continuous sheet of plastic-coated paper, with the mesh fragments and the handles placed in theirs final position Figure 4: shows several models of bag that can be obtained.

The windows are closed off by suitable fragments of formal dimensionally correct mesh. There is also the option to have groups of perforations that are not closed off with fragments of mesh in order to increase the aeration of the packaged products.
In order to increase the bag's mechanical resistance in the areas envisaged to be heat-sealed, such as the handles and on the periphery of the windows, polythene reinforcements are available, these are joined to the continuous sheet by means of heat-sealing or any other similar method. In this embodiment the windows are made following the Welding of the fragments of mesh.
In Figure 4 we can see the various types of bag that can be obtained from the continuous band of plastic-coated paper, which is the object of the present invention.
