Abstract

Continuous band of reinforced plasticized paper for the manufacture of bags of fruit and vegetable products and the like comprising a first continuous sheet of plasticized paper on at least one of its faces, a second continuous sheet of plastic material of approximately reticular form joined together by any of the known methods. In the first continuous sheet of paper four first windows are arranged in the areas where the transverse joining lines and the folding folds converge to prevent deterioration of the first continuous sheet of paper when making the folds. The use of the second continuous sheet of plastic material increases the strength of the paper and improves its behavior before the joints made, for example, by thermowelding.

Como se ha explicado anteriormente, la utilización de la segunda lámina continua tiene dos objetivos fundamentales, el primero es aumentar la resistencia mecánica del papel y el segundo mejorar el comportamiento de la primera lámina de papel en los procedimientos de unión mediante pegado, termosoldadura, ultrasonidos o métodos similares. Para cumplir los 10 dos objetivos anteriores, se dispone unos refuerzos (12) de material plástico entre la primera lámina continua de papel y la segunda lámina continua que pueden estar situados, bien en uno o en todos de los lugares que a continuación 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 15 primera lámina continua y la segunda lámina continua o en los bordes de las ventanas de ventilación. 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, heat welding, ultrasound or similar methods. In order to fulfill 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 windows of ventilation

La primera unión transversal puede formar una solapa en la que se disponen dos o más orificios (13) troquelados a modo de asa que facilitan la manipulación del producto y su 20 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 handling of the product and its setting in value in the places of sale.

Como se ha hecho mención en los párrafos anteriores la unión transversal superior y la unión transversal inferior se pueden realizar mediante pegado, termosoldadura, ultrasonidos u otro procedimiento similar. 25 As mentioned in the previous paragraphs, the upper transverse junction and the inferior transverse junction can be performed by gluing, welding, ultrasonic or other similar procedure. 25
