Description
Embalaje VFFS/HFFS con ayuda de apertura en la costura longitudinal y procedimiento para la realización de dicho embalaje.VFFS / HFFS packaging with opening aid in the longitudinal seam and procedure for performing said packaging.
La presente invención se refiere a un embalaje
flexible y en particular a un embalaje de rellenado y sellado,
vertical y horizontal (VFFS/HFFS) con una estructura de entrada
continua en la costura longitudinal de dicho emba-
laje.The present invention relates to a flexible packaging and in particular a filling and sealing, vertical and horizontal (VFFS / HFFS) packaging with a continuous input structure in the longitudinal seam of said package.
laje.
Las bobinas de las máquinas embaladoras VFFS/HFFS presentan, en la dirección de extrusión de la película plástica, un comportamiento al desgarro incontrolado y el desgarro tiende a continuar en la dirección de extrusión. La mayoría de los embalajes VFFS/HFFS están situados de modo que la longitud del embalaje sea paralela a la dirección de extrusión de la película. La consecuencia de esta situación es que la costura cruzada o costura transversal del embalaje suele comprender las iniciaciones de apertura del embalaje. Las iniciaciones de la apertura de mayor uso son estructuras dentadas ininterrumpidas en la costura transversal del embalaje VFFS/HFFS. La apertura del embalaje, en la parte superior de dicho embalaje VFFS/HFFS, que comprende una estructura dentada como iniciaciones de apertura, según se indicó con anterioridad, suele dar lugar a un desgarro incontrolado en la dirección de extrusión de la película de plástico (dirección de la máquina).The coils of the packing machines VFFS / HFFS present, in the film extrusion direction plastic, uncontrolled tear behavior and tear tends to continue in the extrusion direction. Most of the VFFS / HFFS packages are located so that the length of the Packing is parallel to the extrusion direction of the film. The consequence of this situation is that the cross stitching or transversal seam of the packaging usually includes the initiations Packaging opening. The initiations of the major opening use are unbroken serrated structures in the seam Transverse packing VFFS / HFFS. The opening of the packaging, in the upper part of said VFFS / HFFS package, which comprises a serrated structure as opening initiations, as indicated previously, it usually results in an uncontrolled tear in the extrusion direction of the plastic film (direction of the machine).
En la técnica anterior, varios documentos presentan iniciaciones de apertura tales como incisiones o muescas "en forma de V" en el sellado longitudinal.In the prior art, several documents present opening initiations such as incisions or notches "V-shaped" in the longitudinal seal.
La patente US nº 5.409.115 da a conocer un
embalaje de bolsa tubular para material de tipo venda. Este embalaje
presenta por lo menos una iniciación de apertura en la costura
longitudinal situada entre espacios longitudinales continuamente
recurrentes con lengüetas de desgarre entre muescas para la
limitación del desgarre en otro sentido. En este embalaje, la
estructura dentada está interrumpida por espacios longitudinales que
definen lengüetas de desgarro de anchuras posiblemente diferentes.
La estructura de iniciación de apertura, en la costura
longitudinal, se consigue durante el procedimiento de VFFS/HFFS, que
disminuye la velocidad de embalaje. Además, la clase de iniciación
de apertura, en la costura longitudinal, genera desechos en el
procedimiento de VFFS/HFFS porque se elimina
material.US Patent No. 5,409,115 discloses a tubular bag packaging for bandage type material. This packaging has at least one opening initiation in the longitudinal seam located between continuously recurring longitudinal spaces with tearing tabs between notches for the limitation of tearing in another direction. In this packaging, the toothed structure is interrupted by longitudinal spaces that define tear tabs of possibly different widths. The opening initiation structure, in the longitudinal seam, is achieved during the VFFS / HFFS procedure, which decreases the packing speed. In addition, the opening initiation class, in longitudinal seam, generates waste in the VFFS / HFFS procedure because it is eliminated
material.
El documento CH 651.795 A5 da a conocer un embalaje VFFS/HFFS con iniciaciones de apertura en la costura longitudinal de dicho embalaje. En este caso, las iniciaciones de apertura son incisiones cortadas presentes en posiciones determinadas de dicha costura. No se elimina ningún material en esta técnica. No obstante, la estructura dentada no es una estructura continua e ininterrumpida. Una estructura dentada continua permite el desgarro del embalaje en una dirección transversal a la dirección de extrusión (dirección de la máquina) en cualquier posición de la costura. Además, las incisiones han sido conseguidas durante el procedimiento de VFFS/HFFS, de nuevo disminuyendo la velocidad de embalaje.Document CH 651.795 A5 discloses a VFFS / HFFS packing with opening seams longitudinal of said packaging. In this case, the initiations of opening are cut incisions present in positions determined from said seam. No material is removed in this technique. However, the toothed structure is not a structure continuous and uninterrupted A continuous toothed structure allows the tear of the packaging in a direction transverse to the extrusion direction (machine address) in any sewing position. In addition, the incisions have been obtained during the VFFS / HFFS procedure, again decreasing the packing speed
El documento EP 0 400 577 A1 da a conocer microcortes en el margen lateral. Este tipo de microcortes representa iniciaciones de desgarro no controlables para películas poliméricas orientadas.EP 0 400 577 A1 discloses microcuts on the lateral margin. This type of micro cuts represents tear initiations not controllable for movies oriented polymers.

La presente invención da a conocer un embalaje VFFS/HFFS con una estructura dentada continua presente en por lo menos la costura longitudinal de dicho embalaje. La expresión "estructura dentada continua" debe entenderse como incisiones "en forma de V" sustancialmente no interrumpidas denominadas también muescas adyacentes o muescas contiguas según se representa en las diferentes figuras en relación con la presente invención. La expresión "muescas contiguas" o "muescas adyacentes" se utiliza indistintamente en el texto.The present invention discloses a packaging VFFS / HFFS with a continuous toothed structure present in minus the longitudinal seam of said packaging. The expression "continuous toothed structure" should be understood as incisions "V-shaped" substantially uninterrupted called also adjacent notches or contiguous notches as represented in the different figures in relation to the present invention. The expression "contiguous notches" or "adjacent notches" is used interchangeably in the text.
Dicha estructura dentada se crea simultáneamente con el corte de la película de extrusión en la anchura correcta para las bobinas de máquinas embaladoras. El primer lado de la película cortada en una "forma en V" representa la contrapartida del segundo lado, de tal modo que no permanece ninguna línea de corte horizontal, permitiendo un corte libre de desechos (véase Figura 8). En la patente US nº 5.409.115, el corte deja líneas de corte que son paralelas a la costura, lo que no permite el desgarro de la película en cualquier lugar. Además, el corte de la película dado a conocer en la patente US nº 5.409.115 genera desechos y ha de realizarse durante la operación de embalaje para obtener lengüetas de desgarro adecuadas.Said toothed structure is created simultaneously. with the cutting of the extrusion film in the correct width for the coils of packing machines. The first side of the film cut in a "V-shape" represents the counterpart of the second side, so that no remains horizontal cutting line, allowing a waste-free cut (see Figure 8). In US Patent No. 5,409,115, the cut leaves cutting lines that are parallel to the seam, which does not allow tearing the film anywhere. In addition, the cut of the film disclosed in US Patent No. 5,409,115 generates waste and must be done during the packing operation to get suitable tear tabs.
Existen diferentes posibilidades para crear dicha estructura dentada por medios bien conocidos por los expertos en esta materia (corte por láser, corte por chorro de agua, corte por cuchilla giratoria, etc.). La estructura dentada puede consistir en muescas adyacentes grandes o pequeñas, dependiendo de la aplicación.There are different possibilities to create said jagged structure by means well known to the experts in this matter (laser cutting, water jet cutting, cutting by rotating blade, etc.). The toothed structure can consist of large or small adjacent notches, depending on the application.
En la técnica anterior, la estructura dentada en la costura transversal del embalaje se consigue mediante un dispositivo de corte durante la operación de corte y sellado transversal. Si las muescas son grandes, las barras de sellado en el sellado transversal deben estar mucho más extendidas que si el corte cruzado fuera un corte recto. Lo que es bien conocido por los expertos en esta materia. La consecuencia de esta dispersión es una longitud globalmente mayor del embalaje que representa pérdidas del material de embalaje. Situando la estructura dentada continua sobre los bordes laterales de la bobina, la longitud global del embalaje se reduce en una longitud X, donde X representa hasta un 10%. Este principio se ilustra en la Figura 6a (técnica anterior) y 6b (invención).In the prior art, the toothed structure in The transverse seam of the packaging is achieved by cutting device during cutting and sealing operation cross. If the notches are large, the sealing bars in the transverse seal must be much more extended than if the cross cut out a straight cut. What is well known to Experts in this field. The consequence of this dispersion is a overall length of the packaging representing losses of Packing material. Placing the toothed structure continues on the side edges of the coil, the overall length of the packaging it is reduced by a length X, where X represents up to 10%. This principle is illustrated in Figure 6a (prior art) and 6b (invention).
La estructura dentada interrumpida por espacios longitudinales recurrentes para obtener lengüetas de desgarro, según se ilustra en la patente US nº 5.409.115, requiere la separación por corte de material y genera residuos durante el procedimiento. Como se indicó anteriormente, la generación de desechos en un procedimiento de embalaje VFFS/HFFS es un importante inconveniente. En el caso de la presente invención, la estructura dentada continua está directamente disponible en la bobina (véase Figura 5) sin ningún desecho, exceptuado el desecho de las hendiduras laterales usuales Y, según se representa en la Figura 8.Toothed structure interrupted by spaces Recurrent lengths to obtain tear tabs, as illustrated in US Patent No. 5,409,115, it requires the separation by cutting of material and generates waste during the process. As indicated above, the generation of waste in a packaging procedure VFFS / HFFS is an important inconvenient. In the case of the present invention, the structure Continuous toothed is directly available in the coil (see Figure 5) without any waste, except for waste disposal usual side slits Y, as shown in Figure 8.
Por lo tanto, el primer motivo para situar la estructura dentada continua sobre la costura longitudinal es que la longitud total del embalaje VFFS/HFFS se puede reducir en hasta un 10%, lo que representa un considerable ahorro de material de embalaje, sin generar ningún desecho adicional.Therefore, the first reason to place the continuous toothed structure on the longitudinal seam is that the Total packing length VFFS / HFFS can be reduced by up to 10%, which represents a considerable material savings of packaging, without generating any additional waste.
El segundo motivo para situar la estructura dentada continua sobre la costura longitudinal es la posibilidad de desgarrar el embalaje en una dirección transversal a la dirección de extrusión de la película (véase Figuras 9a y 9b). Esto permite una apertura más predecible y a veces, una apertura particular del embalaje según se ilustra en la Figura 4. El hecho de que la estructura dentada sea una estructura continua permite, además, un desgarro en cualquier posición sobre la costura longitudinal.The second reason to place the structure Continuous toothed on the longitudinal seam is the possibility of tear the packaging in a direction transverse to the direction of extrusion of the film (see Figures 9a and 9b). This allows a more predictable opening and sometimes a particular opening of the packaging as illustrated in Figure 4. The fact that the serrated structure be a continuous structure also allows a tear in any position on the longitudinal seam.
La fabricación de dichas bobinas de máquina embaladora se representa en la Figura 8. El residuo de hendidura lateral Y está siempre presente, incluso en el corte tradicional, y se mantiene lo más pequeño posible.The manufacture of said machine coils packing machine is represented in Figure 8. The slit residue lateral And it is always present, even in the traditional cut, and It stays as small as possible.
Una bobina acabada se representa en la Figura 5 y su uso en una máquina embaladora VFFS/HFFS se representa en la Figura 7.A finished coil is represented in Figure 5 and its use in a VFFS / HFFS packing machine is represented in the Figure 7
La presencia de la estructura dentada en la
bobina de la máquina no tiene influencia alguna sobre la velocidad
de funcionamiento de la máquina embaladora, porque la cuchilla de
corte no desacelera el procedimiento de VFFS/
HFFS.The presence of the toothed structure in the machine coil has no influence on the operating speed of the packing machine, because the cutting blade does not slow down the VFFS /
HFFS
El hecho de que la estructura dentada esté presente desde el principio en la bobina de la máquina presenta la consecuencia de que la estructura dentada de ambos lados de la bobina nunca esté perfectamente superpuesta 8 sobre la costura longitudinal según se da a conocer en la patente US nº 5.409.115. Esta situación se representa en la Figura 10. No obstante, esto no tiene efecto alguno sobre las posibilidades de desgarro en la dirección cruzada de la dirección de extrusión de la película de plástico, porque la iniciación del desgarro está todavía presente.The fact that the toothed structure is present from the beginning in the machine coil presents the consequence of the jagged structure of both sides of the coil is never perfectly superimposed 8 on the seam longitudinal as disclosed in US Patent No. 5,409,115. This situation is represented in Figure 10. However, this does not has any effect on the chances of tearing in the cross direction of the extrusion direction of the film plastic, because the tear initiation is still Present.
Otra ventaja de la presente invención es una
influencia positiva en la evidencia de manipulación indebida para
la apertura de desgarro. En un embalaje VFFS/HFFS de la técnica
anterior, la parte superior sellada en sentido transversal se puede
desgarrar tirando del sellado de aletas de dicho embalaje. Si las
costuras longitudinales (sellados) están provistas de una
estructura dentada continua, el embalaje comenzará a desgarrarse en
el borde longitudinal antes de que se pueda iniciar el
desprendimiento. Esto hace casi imposible abrir y volver a sellar
el embalaje sin desgarro asegurando de esta manera una prueba de
manipulación indebida (evidencia de manipulación
indebida).Another advantage of the present invention is a positive influence on the evidence of tampering for the tear opening. In a prior art VFFS / HFFS package, the sealed cross-sectional upper part can be torn by pulling the fin seal of said packaging. If the longitudinal (sealed) seams are provided with a continuous toothed structure, the packaging will begin to tear at the longitudinal edge before detachment can begin. This makes it almost impossible to open and reseal the packaging without tearing, thus ensuring proof of tampering (evidence of tampering
improper).
Los materiales plásticos adecuados para el embalaje VFFS/HFFS obtenidos mediante una bobina provista de una estructura dentada continua no están limitados. Ejemplos representativos ampliamente utilizados en el mercado son BOPP, PET, PS, PE, PA, CPP, en combinaciones monocapa o multicapas, así como laminados con papel o películas metalizadas, etc.The plastic materials suitable for VFFS / HFFS packaging obtained by means of a coil provided with a Continuous toothed structure are not limited. Examples Representatives widely used in the market are BOPP, PET, PS, PE, PA, CPP, in monolayer or multilayer combinations, as well as laminated with metallized paper or films, etc.
