The present invention relates to a continuous band, which has been specially designed for the manufacture of bags for fruit and vegetable products and the like, by longitudinal heat welding of said band through its longitudinal edges, to convert it into a continuous tube, and by cross cutting and welding parallel to said cut, to obtain the unitary bags, closing and independence of the same.
El objeto de la invención es conseguir una banda continua que incorpore dos placas rectangulares de material plástico y una serie de ventanas y, en su caso, perforaciones, de la cual se pueda obtener, mediante la unión de sus bordes por termosoldadura, una bolsa, dos de cuyos laterales son rígidos, y que una vez llenada con el producto a envasar adopta una forma similar a una bandeja o cesta y que tiene una o más perforaciones, en orden a obtener una máxima resistencia mecánica de la bolsa, una correcta aireación de los productos, una óptima protección de los productos contenidos en la misma frente al aplastamiento, una mayor capacidad de impresión en la bolsa y una mayor rapidez en la fabricación de la bolsa y en su llenado. The object of the invention is to achieve a continuous band that incorporates two rectangular plates of plastic material and a series of windows and, where appropriate, perforations, from which it is possible to obtain, by joining its heat-welded edges, a bag, two of whose sides are rigid, and that once filled with the product to be packaged, it adopts a shape similar to a tray or basket and that has one or more perforations, in order to obtain a maximum mechanical resistance of the bag, a correct aeration of the products, an optimal protection of the products contained therein against crushing, a greater printing capacity in the bag and a faster manufacturing of the bag and its filling.
Antecedentes de la invención. Background of the invention.
Determinados productos hortofrutícolas, como tomates, cerezas, naranjas, etc., se comercializan desde hace tiempo en cestas de papel o cartón o cajas de madera o plástico que en muchos casos están protegidas y envueltas en bolsas de plástico perforadas o no que permiten tanto la aireación del producto, la visualización directa del producto, su protección frente al aplastamiento y facilitan su almacenaje o exposición en los expositores y lineales de los puntos de venta. Certain fruit and vegetable products, such as tomatoes, cherries, oranges, etc., have long been marketed in paper or cardboard baskets or wooden or plastic boxes that in many cases are protected and wrapped in perforated or not plastic bags that allow both product aeration, display Direct product, protection against crushing and facilitate storage or exposure in the exhibitors and linear points of sale.
Las anteriores cestas o cajas se han de llenar de los citados productos manualmente o mediante máquinas con velocidades de producción bajas. Además, posteriormente estas cestas o cajas han de ser envueltas en bolsas de material plástico. El proceso de envasado de los productos hortofrutícolas en dichas cestas o cajas es lento y los materiales tienen un coste elevado. The above baskets or boxes must be filled with the aforementioned products manually or by machines with low production speeds. In addition, later these baskets or boxes have to be wrapped in plastic bags. The process of packaging the fruit and vegetable products in these baskets or boxes is slow and the materials have a high cost.
