Realizacion preferente de la invention  Preferred embodiment of the invention

Las figuras 1 y 2 muestran una realizacion preferente de la banda continua (1) objeto de la presente description. La banda continua (1) comprende una primera lamina continua de papel (2) plastificado por sus dos caras y una segunda lamina continua (3) de material plastico, preferentemente polietileno extrusionado o laminado, de forma reticular. En cada uno de los sectores (4), definidos por las llneas de corte, correspondientes a cada una de las bolsas unitarias de la primera lamina continua se dispone dos primeras ventanas (5) troqueladas, las referidas primeras ventanas estan situadas en la zona de la banda continua destinada a realizar la union superior transversal y la union inferior transversal del sector contiguo, una de las referidas primeras ventanas esta situada en el primer pliegue (10) y la otra primera venta esta situada en el segundo pliegue (11). El primer y el segundo pliegue se realizan durante el proceso de union de los bordes longitudinales de la banda continua, junto con pliegues complementarios, para que las bolsas presente caras laterales al extenderse o ser llenadas. Es en las zonas de la banda continua donde confluyen las uniones transversales y los pliegues donde existe riesgo de rotura de la lamina continua deFigures 1 and 2 show a preferred embodiment of the continuous band (1) object of the present description. The continuous strip (1) comprises a first continuous sheet of paper (2) plasticized on its two faces and a second continuous sheet (3) of plastic material, preferably extruded or laminated polyethylene, in a reticular manner. In each of the sectors (4), defined by the cutting lines, corresponding to each of the unitary bags of the first continuous sheet, there are two first windows (5) stamped, the said first windows are located in the area of the continuous band destined to realize the transverse upper union and the transverse inferior union of the adjoining sector, one of said first windows is located in the first fold (10) and the other first sale is located in the second fold (11). The first and second folds are made during the process of joining the longitudinal edges of the continuous band, together with complementary folds, so that the bags present lateral faces when extending or being filled. It is in the areas of the continuous band where the cross joints and the folds meet where there is a risk of rupture of the continuous sheet of

papel lo que se evita con las primeras ventanas. Una o mas ventanas de ventilacion (6) se disponen en la lamina continua de papel para la aireacion del producto y para que el consumidor pueda ver, por ejemplo, el estado del producto envasado. Por estas ventanas de ventilacion se puede rasgar facilmente la segunda lamina continua para poder acceder al interior de las bolsa y no romper la banda evitando que el producto se desparrame.paper what is avoided with the first windows. One or more ventilation windows (6) are arranged in the continuous sheet of paper for the aeration of the product and so that the consumer can see, for example, the condition of the packaged product. Through these ventilation windows you can easily tear the second continuous sheet to access the inside of the bag and not break the band preventing the product from spreading.

Como se ha explicado anteriormente, la utilization de la segunda lamina continua tiene dos objetivos fundamentales, el primero es aumentar la resistencia mecanica del papel y el segundo mejorar el comportamiento de la primera lamina de papel en los procedimientos de union mediante pegado, termosoldadura, ultrasonidos o metodos similares. Para cumplir los dos objetivos anteriores, se dispone unos refuerzos (12) de material plastico entre la primera lamina continua de papel y la segunda lamina continua que pueden estar situados, bien en uno o en todos de los lugares que a continuacion se describen, como en las zonas destinadas a las uniones longitudinales y transversales, en los bordes de las primeras ventanas, en los bordes de las segundas ventanas, dichos refuerzos se disponen entre la primera lamina continua y la segunda lamina continua o en los bordes de las ventanas de ventilacion.As explained above, the use of the second continuous sheet has two fundamental objectives, the first is to increase the mechanical strength of the paper and the second to improve the behavior of the first sheet of paper in bonding procedures by gluing, welding, ultrasonic or similar methods. To meet the two previous objectives, reinforcements (12) of plastic material are arranged between the first continuous sheet of paper and the second continuous sheet that can be located, either in one or all of the places described below, as in the areas intended for longitudinal and transverse joints, at the edges of the first windows, at the edges of the second windows, said reinforcements are arranged between the first continuous sheet and the second continuous sheet or at the edges of the ventilation windows .

La primera union transversal puede formar una solapa en la que se disponen dos o mas orificios (13) troquelados a modo de asa que facilitan la manipulation del producto y su puesta en valor en los lugares de venta.The first transverse joint can form a flap in which two or more holes (13) are cut by way of a handle that facilitate the manipulation of the product and its value in the places of sale.

Como se ha hecho mention en los parrafos anteriores la union transversal superior y la union transversal inferior se pueden realizar mediante pegado, termosoldadura, ultrasonidos u otro procedimiento similar.As mentioned in the previous paragraphs, the upper transverse junction and the lower transverse junction can be performed by gluing, welding, ultrasonic or other similar procedure.
