Definitions

• the present invention relates to a continuous band of piastified paper, which has been specially designed for the subsequent manufacture of bags for fruit and vegetable products and the like, by longitudinal heat welding or any other similar process of said band through its longitudinal edges, for turn it into a tube that is also continuous, and by means of parallel welding and cross-cutting, to obtain the unit bags, closure and their independence.
• the object of the invention is to achieve a continuous web that combines areas of fully closed piastified paper with mesh areas and, where appropriate, with perforations, in order to allow visualization and, especially, the aeration of the products packaged therein, with a maximum mechanical resistance of the bag, an optimal protection of the products contained against the light, a greater capacity of printing of the bag, a faster manufacturing, a recyclable bag and a reduction of the thickness and weight of the piastified paper and therefore a lower cost.
• Certain fruit and vegetable products such as oranges, potatoes, etc., have been commercialized for a long time in plastic bags, of reticular structure, which allow both the aeration of the product as the display of it.
• the best solution to date adopted belongs to the same holder as that of this invention and consists of a plastic laminar band to which a series of openings are made that are closed by a reticular material attached to the sheet by heat welding or process Similary.
• the continuous band proposed by the present invention constitutes a technological advance in this field and is based on the use of a continuous sheet of plasticized paper, unique, of a width coinciding with that of the band itself! type in which said band is intended to close on itself, by joining its longitudinal edges by heat welding, to configure a fragmented continuous tube in a plurality of sectors corresponding to respective bags, said continuous band has one or more windows and, where appropriate, perforations of the same or different size that can be closed with the collaboration of a network fragment, formally and dimensionally appropriate to each window and fixed to the periphery of the same.
• the continuous band is constituted from a continuous sheet of plasticized paper on at least one of its faces, of a width equal to said continuous band; continuous sheet of plasticized paper to which, in correspondence with each of the sectors of the same provided for the obtaining of a bag, polyethylene reinforcements are provided in the areas provided for the handles, the thermosoldauras and on the edges or periphery of the windows and, where appropriate, perforations, attached to the laminated paper sheet by heat welding or similar procedure.
• a! less a window which closes with the collaboration of a network fragment, formally and dimensionally appropriate to said window and fixed by heat welding to the periphery of said window.
• the laminated paper sheet can be laminated on both sides.
• the window is centered centered on the longitudinal axis of the continuous laminated paper sheet, and on both sides thereof They establish small perforations, lacking net.
• the net that closes the window is a continuous strip of net that runs the continuous plastic sheet longitudinally.
• a second polyethylene reinforcement fixed to the polyethylene reinforcement can be provided by heat welding or by any other means, with the particularity that the second reinforcement is fixed to the polyethylene reinforcement on the surface of the latter outside a "U" strip delimited by a die cut line that affects both the polyethylene reinforcement and the laminated paper sheet, strip that constitutes a handle intended to emerge through the mouth of the body of the bag.
• the determining punching lines of the "U" strip can be precut or sliding lines that keep said "U” strip in a copianar arrangement with the rest of the polyethylene reinforcement and the sheet of piastified paper.
• each sector of the band destined to obtain a bag incorporates polyethylene reinforcements in correspondence with two points of the mouth of Sa bag located in diametral opposition, so that the base incorporates two emergent handles of said bag recess and also in diametral opposition.
• Figure 1 shows the laminated paper sheet with fixed polyethylene reinforcement cough
• Figure 2 shows an exploded view of the sheet with the perforated windows and perforations and the net fragments and the handles.
• Figure 3 shows the continuous band of plasticized paper with the net fragments and the handles arranged in their final position
• Figure 4 shows various models of bags that can be obtained. List of references used
• the continuous web of plasticized paper for the manufacture of bags is constituted from a sheet of continuous plasticized paper, in
• the paper is plasticized on both sides, of a width coinciding with the width of the plasticized paper band itself and therefore of a width that is double the size of the bag to be obtained, along the laminated paper sheet.
• windows have groupings of windows, obtained by die-cutting, of different sizes and shapes, there being at least one centered window on which the front face of the beret must be, and in this embodiment another pair of windows of greater length located on the sides of the central window
• the windows are closed by formally and dimensionally appropriate network fragments. Clusters of perforations not closed by net fragments can also be provided as an option to increase the aeration of Sos packaged products.
• polyethylene reinforcements connected to the continuous sheet are arranged in said areas by means of heat welding or any other similar procedure.
• the windows are made after welding the network fragments.
• Figure 4 shows various types of bags that can be obtained from the continuous web of plasticized paper object of the present invention.
