Description
Medio de envasado multipared en forma de saco.Multipared packaging medium in the form of coat.
La invención concierne a un medio de envasado multipared en forma de saco para materiales en partículas, especialmente materiales en forma de polvo.The invention concerns a packaging medium bag-shaped multipared for particulate materials, especially powder materials.
Los materiales en forma de polvo, por ejemplo polvo de polímero, se ponen en el mercado envasados en los llamados sacos con válvula. El llenado se efectúa aquí por medio de máquinas llenadoras que funcionan con un alto rendimiento y que cargan el polvo en el saco en estado fluidizado con mucho aire. El aire tiene que escapar entonces del saco con la mayor rapidez posible. Como material de envasado se han utilizado en el pasado sacos de papel kraft, dado que el aire puede escapar a través del papel, mientras que se retiene el producto de carga en forma de polvo. Sin embargo, los sacos de papel adolecen del inconveniente de que sólo retienen en grado insuficiente el agua de salpicaduras y la humedad y son sensibles frente a una carga mecánica.Materials in powder form, for example polymer powder, put on the market packaged in the so-called bags with valve. Filling is done here by machines fillers that operate with high performance and that load the powder in the bag in a fluidized state with a lot of air. The air has to escape from the bag as quickly as possible. How packaging material paper bags have been used in the past kraft, since air can escape through the paper, while that the cargo product is retained in powder form. But nevertheless, paper sacks suffer from the disadvantage that they only retain insufficiently splash water and moisture and are sensitive to a mechanical load.
Para superar estos inconvenientes, se emplean actualmente sacos multipared con válvula que están constituidos en su interior por un saco de papel que está rodeado en su exterior por un saco de una película de plástico, usualmente una película de polietileno. Para garantizar una rápida salida del aire durante el llenado, la película de plástico que envuelve al saco de papel está perforada al menos en una zona parcial de la superficie. Es cierto que se mejora así netamente la resistencia mecánica en comparación son sacos de papel, pero, debido a la perforación de gran superficie, no se puede suprimir enteramente la penetración de humedad.To overcome these inconveniences, they are used currently multipared bags with valves that are constituted in inside by a paper sack that is surrounded on the outside by a sack of a plastic film, usually a film of polyethylene. To ensure a rapid release of air during the filled, the plastic film that wraps around the paper sack is perforated at least in a partial area of the surface. It is true that the mechanical resistance is clearly improved in comparison they are paper sacks, but, due to the large perforation surface, the penetration of humidity.
Por tanto, existía el problema de desarrollar un material de envasado, especialmente para un producto de carga en forma de polvo, que deje que escape el aire con la mayor rapidez posible durante el proceso de llenado y que, durante el almacenamiento, impida lo más eficazmente posible la rehumectación proveniente del aire ambiente, así como ofrezca protección contra agua de salpicaduras.Therefore, there was the problem of developing a packaging material, especially for a cargo product in dust form, let the air escape as quickly possible during the filling process and that, during the storage, prevent rewetting as effectively as possible from ambient air, as well as offer protection against splashing water
El documento US-A 5 493 844 describe un medio de envasado en el que una capa interior de la envoltura está perforada y ésta es solapada por una capa exterior en la zona perforada. En toda la longitud de la zona de solapamiento está abierta una costura longitudinal para asegurar la rápida ventilación durante el llenado. Después del llenado, se cierra esta costura longitudinal por medio de un proceso de sellado en caliente.US-A 5 493 844 describes a packaging means in which an inner layer of the wrap is perforated and this is overlapped by an outer layer in the perforated area. In the entire length of the area of overlap is open a longitudinal seam to ensure the Quick ventilation during filling.

El material interior 9 permeable al aire está unido mediante pegadura con el material exterior 10 impermeable al aire. Preferiblemente, una capa interior de papel 9 está pegada con una película exterior de plástico 10 solamente en el extremo superior 6 y en el fondo 7. Durante la fabricación se procede aquí de modo que las distintas capas del saco sean trasladadas desde el rollo hasta la cadena de producción y sean allí reunidas. Se conforma un tubo flexible sinfín y se corta éste de manera correspondiente. A continuación, se pliegan los extremos y se coloca y pega la abertura de la válvula. Por último, se pega una hoja de cubierta en ambos extremos del saco.The air permeable inner material 9 is bonded together with the outer material 10 impervious to the air. Preferably, an inner layer of paper 9 is glued with an outer plastic film 10 only at the end top 6 and bottom 7. During manufacturing proceed here so that the different layers of the bag are moved from the Roll to the production line and be gathered there. Be it forms an endless flexible tube and it is cut so correspondent. Then the ends are folded and place and paste the valve opening. Finally, it sticks a cover sheet on both ends of the bag.
El material exterior 10, en general una película de plástico, forma un solapamiento en el lado delantero 3 o en el lado trasero 2 o en ambos lados sobre una zona parcial 11 de hasta un 50% de la longitud total de los lados delantero o trasero 2, 3. Preferiblemente, la pared exterior 10 forma un solapamiento solamente en uno de los dos lados y de manera especialmente preferida tan sólo en el lado trasero 2, esto es, el lado sobre el que descansa en general el saco. En otra forma de realización preferida la película de plástico forma un solapamiento en toda la longitud. La zona de solapamiento 11 es preferiblemente de 10 a 50% de la superficie total del respectivo lado.The outer material 10, in general a film plastic, forms an overlap on the front side 3 or on the rear side 2 or both sides on a partial area 11 of up to 50% of the total length of the front or rear sides 2, 3. Preferably, the outer wall 10 forms an overlap only on one of the two sides and especially preferred only on the back side 2, that is, the side on the which generally rests the sack. In another embodiment preferred the plastic film forms an overlap throughout the length. The overlap zone 11 is preferably 10 to 50% of the total area of the respective side.
En la zona de solapamiento 11 está perforada la capa interior 10a de la película de plástico. La densidad de perforación es en general de 0,5 a 5 agujeros por cm^{2}. La perforación puede aplicarse por medio de tratamiento con agujas a lo largo de toda la zona de solapamiento 11 o de una zona parcial de ésta. Una proporción de 10 a 50% de la superficie de la zona de solapamiento 11 es provista de la perforación. Preferiblemente, se perfora en toda la longitud de la zona de solapamiento. Se mantiene una distancia de 0,5 a 10 cm con respecto a los bordes 12 y 13 de la zona de solapamiento 11, siendo preferiblemente de 2 a 10 cm la distancia al borde 12 de la zona de solapamiento, que está abierto. El tamaño de los agujeros, la densidad de perforación y la superficie perforada dependen sustancialmente de lo grande que haya de ser el paso de aire durante el llenado. Estos tamaños pueden ser ajustados por el experto dentro de los límites antes citados según lo que se requiera.In the overlap zone 11 the inner layer 10a of the plastic film. The density of drilling is generally 0.5 to 5 holes per cm2. The perforation can be applied by needle treatment to along the entire overlap zone 11 or a partial zone of is. A proportion of 10 to 50% of the area of the area of overlap 11 is provided with the perforation. Preferably, it Drills the entire length of the overlap zone. It keeps a distance of 0.5 to 10 cm from the edges 12 and 13 of the overlap zone 11, preferably 2 to 10 cm being the distance to edge 12 of the overlap zone, which is open. The size of the holes, the drilling density and the perforated surface depend substantially on how large of being the passage of air during filling. These sizes can be adjusted by the expert within the aforementioned limits according to what is required.
En los bordes 12 y 13 de la zona de solapamiento la capa interior 10a y la capa exterior 10b de la película de plástico están unidas una con otra, por ejemplo mediante una costura de pegado o una costura de soldadura 14, 15. Para dejar que salga el aire que escapa debido a la perforación, se interrumpe la unión en uno o en ambos bordes, preferiblemente tan sólo en un borde. En general, se interrumpe la unión en una zona 16 que comprende de 10 a 50% de la longitud total. Preferiblemente, la interrupción está situada en la mitad superior y de manera especialmente preferida en el tercio superior del medio de envasado 1, ya que el aire residual se concentra arriba durante el proceso de llenado.At edges 12 and 13 of the overlap zone the inner layer 10a and the outer layer 10b of the film of plastic are joined together, for example by sewing glue or weld seam 14, 15. To let it out the air that escapes due to the perforation, the union is interrupted on one or both edges, preferably only on one edge. In In general, the junction is interrupted in an area 16 comprising 10 at 50% of the total length. Preferably, the interruption is located in the upper half and especially preferably in the upper third of the packaging medium 1, since the residual air It concentrates above during the filling process.
Con esta construcción se garantiza, por un lado, que el aire pueda salir rápidamente durante el llenado a pesar de las paredes exteriores hechas de una película de plástico. Cuando se almacenan los sacos llenos, se cierra la abertura de la zona de solapamiento como consecuencia del peso propio del medio de envasado llenado, con el efecto de que no puede penetrar en el interior humedad atmosférica ni agua de salpicaduras a través de la perforación.This construction guarantees, on the one hand, that the air can escape quickly during filling despite The outer walls made of a plastic film. When stored full bags, the opening of the area of overlap as a result of the weight of the packaging medium filling, with the effect that it cannot penetrate inside atmospheric humidity or splashing water through the drilling.
El medio de envasado es adecuado para el transporte y el almacenamiento de materiales en partículas, tales como granulados, fibras o polvos de grano fino o grueso. El medio de envasado es especialmente adecuado para productos de carga sensibles a la humedad.The packaging medium is suitable for transport and storage of particulate materials, such as granules, fibers or powders of fine or coarse grains. The middle of packaging is especially suitable for cargo products moisture sensitive.
