Description
Method and system for producing a multi-layered packaging material The invention relates to a method for producing a multi-layered packaging material for sterilization purposes.
The invention also relates to a system for producing a multi-layered packaging material for sterilization purposes lt is important that medical tools and instruments which are used during a medical intervention are supplied in a sterile fashion.
For this, the instruments to be used must be successively cleaned, disinfected and sterilized.
During mechanical cleaning, a first degree of contamination is removed, whereupon the instruments are disinfected.
The cleaned and disinfected medical tools and/or instruments are then inspected and/or assembled, whereupon they may be placed in an instrument tray.
This instrument tray is then packed into packaging sheet.
The instrument tray is sterilized after packing.
Sterilization is the essential step whereby the required log reduction in microorganisms takes place in order to be able to present the instrument tray in sterile fashion before and/or during a medical intervention. it is essential that a predefined folding pattern is performed for the packing of the instrument tray in the packaging sheet wherein a protocol need to be followed.
In order to guarantee the sterility of the instrument in the instrument tray, it is essential that the ends of the packaging material form a structure, wherein the packaging sheet is folded several times thereby forming a tortuous path.
Such labyrinth-like structure is necessary to prevent microorganisms, particles and similar from being able to penetrate into the instrument tray from the outside via the ends of the packaging material.
In order to further ensure a sufficient packing of the instrument tray, the tray needs to be packed in at least two layers of packaging material.
This can either be done sequentially such that a double wrapping of the instrument tray is obtained or by packing the tray into a double layered packaging sheet.
Such double layered packaging sheet consists of two individual packaging sheets which are sealed to together at their edges.
The benefit of making use of such double layered packaging sheet is that only a single packing step has to be performed.
Welding of the individual sheets in required in order to ensure that the double layered material can be efficiently applied and that the sheets do not separate from another.
it is an object of the invention to provide an improved method and system for producing a multi-layered packaging material for sterilization purposes. The invention provides thereto a method for producing a multi-layered packaging material for sterilization purposes, comprising the steps: a) providing at least one first roll of a first packaging material; b) providing at least one second roll of a second packaging material; c) unwinding at least part of the first packaging material from the first roll; d) unwinding at least part of the second packaging material from the second roll; e) guiding of the first packaging material and the second packaging material towards a parallel configuration; fy subjecting the first packaging material and the second packaging material to at least one sealing step, wherein the first packaging material and the second packaging material are sealed together into a multi-layered packaging material; and g) winding the multi-layered packaging material onto a product roll in particular such that a roll of multi-layered packaging material is obtained.
The method according to the invention has several benefits. The method enables the provision of a roll of multi-layered packaging material which can be used for sterilization purposes. The provision of multi-layered packaging material on a reel is beneficial as this enables more flexibility in the final of use of the obtained product. The multi-layered packaging material can for example be cut into sheets of desired dimensions. This enables customization of sheet production. The roll of multi- layered packaging material can for example also be used in a device for folding an instrument tray into a packaging material, such as but not limited to the device as described in WO2019/009724. The present inventions steps in where the medical field is developing towards further automation and customization of processes. The method further allows for continuous production of rolls of multi-layered packaging material. In particular, the method allows for continuous production of multi-layered packaging material on reels. Further, the storage of rolls is preferred over the storage of sheets due to the efficient spatial shape of a roll. In addition to this, the shelf life of the (medical) multi-layered packaging material can be increased when the multi-layered material is stored upon a roll. Delamination of the first and second packaging material is less likely to occur for rolls when compared to the storage of single multi-layered sheets as material provided on rolls is less exposed to influences of the environment, such as light and air which may affect the seal between the individual layers of packaging material.
Hence, by the provision of the material on a roll as the material the durability of the obtained product may be enhanced.
The multi-layered packaging material as obtained via the method according to the present invention can be used for a single step packing method.
The steps according to the method are typically subsequent steps.
However, the unwinding of at least part of the first packaging material from the first roll and the unwinding of at least part of the second packaging material from the second roll can be at least substantially simultaneous.
Where the term unwinding is used, also the term unrolling can be used.
Where the term winding is used also the term rewinding could be used.
Where the expression winding on a roll is used, also the expression winding on a reel can be used.
Where it said that the packaging materials are guided towards a parallel configuration, it can also be said that the packaging materials are aligned into a parallel configuration and/or that the packaging materials are positioned in a parallel configuration.
It is conceivable that the first and second packaging materials are poisoned upon another.
The packaging material according to the present invention is in particular sterilization wrap.
The packaging material can also be referred to as sterilization wrap and/or autoclave wrap.
The packaging material is typically configured to be used in a sterilization process, such as in a (steam) autoclave.
Hence, the packaging material{s) typically allow(s) steam to penetrate.
It is also conceivable that at least one packaging materials is penetrable for steam and/or ethylene oxide gas.
The first packaging material can have the same composition and/or materials as the second packaging material.
However, it is also conceivable that the first and second packaging materials are made of different materials.
Typically, at least one packaging material, and preferably each packaging material, is a non-woven and/or synthetic material.
At least one packaging material can for example be a polypropylene based material, more in particular a Spunbond Meltblown Spunbond (SMS). Hence, at least one packaging material can be a SMS (tri laminate) non woven fabric.
In a preferred embodiment of the method, at least one sealing step is an ultrasonic sealing step. Ultrasonic sealing or ultrasonic welding is in particular suitable for providing a sealing or welding connection between packaging materials as used in the present invention. A benefit of ultrasonic sealing is that the use of any adhesive can be fully omitted. This is beneficial for the intended use of the invention as the presence of an adhesive of glue would negatively affect a sterilization process. At least one sealing step is preferably a continuous sealing step. This positively contributes to a continuous production process of multi-layered packaging material via a method according to the present invention. It is for example conceivable that during the (continuous) sealing step a predetermined sealing pattern is obtained. In a further preferred embodiment of the method is at least one sealing step configured to seal the edges of the first packaging material and the second packaging material. This step is preferably performed such that the (outer) edges (or sides) of at least one first packaging material are sealed to the outer edges (or sides) of at least one second packaging material. Preferably, the first and second packaging materials have a substantially similar width, in particular such that they can be aligned with respect to another. This is beneficial for both the sealing process and the winding step afterwards. Possibly, unwinding at least part of the first packaging material from the first roll is performed at a first velocity and unwinding at least part of the second packaging material from the second roll is performed at a second velocity, wherein the first velocity substantially equals the second velocity. In this way, a controlled guidance of the first and second packaging materials towards their parallel configuration and/or the sealing step can be ensured. When the first and second packaging material have a substantially similar velocity this may also positively influence the reliability of the sealing step.
It is in particular beneficial if the material tension of the first packaging material substantially equals the material tension of the second packaging material prior to and/or during the at least one sealing step f). This embodiment is beneficial since in this manner at least one sealing step can be further optimized. Due to the first packaging material having a substantially equal material tension a better layered configuration of the multi-layered packaging material can be obtained. By controlling the material tension of the packaging material prior and/or during sealing it can be prevented that an uneven sealing and/or unevenness in the multi-layered material occurs. With the material tension, also the internal pressure in the 5 packaging material can be meant.
It is for example conceivable that the material tension from each packaging material is determined prior to the sealing step, and preferably that the material tension of at least one packaging material can be adjusted based upon said determination. It is for example possible that the material tension of at least one packaging material is adjusted in case a predetermined material tension difference between the (first and second) packaging materials is exceeded. Adjusting of the material tension of a packaging material during application of the method according to the present invention can for example be done by adjusting of the (transport) velocity of the packaging material. The velocity of at least one packaging material, for example during unwinding, can for example be adjusted by subjecting the packaging material to a braking force. In a preferred embodiment, step e) and step f) are substantially simultaneous steps. It is also beneficial if at least one first packaging material and at least one second packaging material enclose a predetermined angle prior to being guided towards a parallel configuration. It is in particular beneficial if the first packaging material and the second packaging material are not able to touch or contact another prior to the sealing step as this may lead to a build-up of static charge. In case static charge is built up, this may negatively affect the sealing step. In case the sealing step cannot be performed in an optimal way, unevenness may be created in the multi-layered packaging material. The parallel configuration of the first and the second packaging material can for example be initiated by guiding the packaging materials through at least one pair of guide rollers and/or pressure rollers. It is for example conceivable that the first packaging material and the second packaging material enclose a predetermined angle prior to being guided into said at least one pair of rollers, in particular such that the packaging materials are guided and/or pressed into a parallel configuration. The angle may for example be between 2 and 170 degrees, preferably between 5 and 90 degrees, more preferably between 10 and 50 degrees.
In a further possible embodiment, the method may comprise the steps of: - providing at least one third roll of a third packaging material; - unwinding at least part of the third packaging material from the third roll; - guiding the third packaging material towards a parallel configuration with the first and second packaging materials during step e); - subjecting the first packaging material, the second packaging material and the third packaging material to at least one sealing step, wherein the first packaging material, the second packaging material and the third packaging material are sealed together into a multi-layered packaging material; and - winding the multi-layered packaging material onto a product roll.
This embodiment of the method enables the provision of a roll of a multi-layered packaging material comprises at least one first packaging material, at least one second packaging material and at least one third packaging material. However, it is also conceivable that multiple first packaging materials and/or multiple second packaging materials are provided and sealed together into a multi-layered packaging material.
The method may possibly comprise the step of unwinding at least part of the multi- layered packaging material from the product roll and cutting of the multi-layered packaging material into at least one sheet. As indicated above, a benefit of the provision of a roll of multi-layered packaging material is that a large flexibility is obtained for the use of the material. Hence, also when cutting the multi-layered packaging material into sheet this can be adjusted to the preferences of the user or to the intended use.
The invention also relates to a roll of multi-layered packaging material obtained via a method according to the present invention.
The invention further relates to a system for producing a (roll of) multi-layered packaging material for sterilization purposes, comprising: - at least two unwinding devices wherein each unwinding device is configured for unwinding at least part of a packaging material from a roll;
- at least one sealer configured for sealing at least two packaging materials into a multi-layered packaging material; - at least one winding device configured for winding a multi-layered packaging material onto a roll; and - at least one control unit configured to independently control at least each unwinding device, at least one sealer and/or at least one winding device.
The system according to the present invention has the same benefits as mentioned for the corresponding method according to the invention.
With regard to the prior art, the system according to the present invention differs in the presence of at least one winding device configured for winding a multi-layered packaging material onto a roll and in the presence of at least one control unit.
As indicated above, also the system benefits of the ability to produce a roll of multi-layered packaging material which has several more application purposes.
The ability to produce a roll of multi- layered packaging material is novel in the field of packaging materials for sterilization purposes as for many years only sheets of packaging material have been produced.
The production of sheets of multi-layered material is significantly easier than the production of a roll of said material.
Nowadays, the production of multi-layered packaging sheets is done by the integration of a sealer in a cutting device for packaging materials.
In this way, a first and a second packaging material are sealed together and cut into sheets directly after the sealing step.
It is relatively easy to introduce a sealer into a cutting device and since only relatively small areas, i.e. the edges of the sheet, need to be sealed the risk of failure is relatively low.
Combining two rolls of packaging material into a new roll of a multi-layered material is a technologic challenge which is overcome by the system and method according to the present invention.
The sealing of the packaging materials of at least two entire rolls of packaging material and subsequently rewinding them into a new roll requires a highly precise aligning of the initial packaging materials, a reliable continuous sealing and highly controlled winding of the relatively thick sealed multi-layered packaging material.
This is enabled by the presence of at least one control unit configured to independently control at least each unwinding device, at least one sealer and/or at least one winding device.
Where it is referred to an unwinding device also an unwinder or unwinding unit can be meant.
This also applies to the winding device which can also be referred to as a winder or winding unit. The system according to the present invention can have multiple control units. At least one control unit can for example be a tension control unit configured to control the tension of at least one packaging material. Preferably at least one tension control unit is at least configured to control the tension of at least one first packaging material and at least one second packaging material prior to and/or during sealing of said materials. At least one control unit can be applied in order to ensure correct aligning of packaging rolls during unwinding and/or rewinding.
In a preferred embodiment, the sealer is an ultrasonic sealer. The (ultrasonic) sealer is preferably configured to seal the edges of at least two packaging materials such that the (outer) edges (or sides) of a first packaging material are sealed to the outer edges (or sides) of a second packaging material.
In a possible embodiment of the system, the system comprises at least one first unwinding device which is configured for unwinding at least part of a first packaging material from a first roll and wherein at least one second unwinding device which is configured for unwinding at least part of a second packaging material from a second roll.
The system may further comprise at least one guide roller configured for guiding at least part of at least one packaging material. It is also conceivable that the system comprises multiple guide rollers in order to further optimize the path of the packaging materials within the system. Preferably, at least one guide roller is positioned between at least one unwinding device an at least one sealer, wherein the guide roller is configured to guide packaging material from at least one unwinding device towards at least one sealer. Preferably at least one guide roller is positioned such that Itis also conceivable that at least one guide roller is applied in combination with at least one brake in order to control the velocity and/or material tension of at least one packaging material. The control unit can be configured to control said at least one brake. lt is for example possible that the velocity and/or material tension of each packaging material can be regulated via at least one brake. The system can also comprises at least one pair of parallel positioned guide rollers. A pair of parallel positioned guide roller may even further optimize guiding of at least one packaging material. The system may also comprise at least one pressure roller and/or at least one pair of pressure rollers.
Further, the system may comprise at least one support unit configured for supporting at least part of a roll of packaging material. Preferably at least one support unit is configured to support the product rol! of multi-layered packaging material as obtained at the winding device. The roll of multi-layered packaging material can be relatively heavy due to its multi-layered configuration.
The method according to the present invention can be carried out by making use of a system according to the present invention. The method may in particular be an automated method. Also the system can be substantially fully automated. The method and system are in particular configured for the continuous production of a roll of multi-layered packaging material.
The invention will be further elucidated by means of non-limiting exemplary embodiments illustrated in the following figures.
Figures ta and 1 b each shows a perspective view of a possible embodiment of the system 100 according to the present invention. Within these figures, similar reference numbers correspond to similar or equivalent elements or features. The system 100 can be applied in order to carry out the method according to the invention. Basically, the steps of the method according to the present invention are visualized in the figures. The system 100 is in particular configured for producing a (roll of) multi-layered packaging material 110 for sterilization purposes. The system 100 comprises a first unwinding device 101 which is configured for unwinding at least part of a first packaging material 111 from a first roll R1 and a second unwinding device 102 configured for unwinding at least part of a second packaging material 112 from a second roll R2. The system 100 further comprises a sealer 103 configured for sealing the two packaging materials 111, 112 into a multi-layered packaging material 110. The system 100 also comprises a winding device 104 which is configured for winding the multi-layered packaging material 110 onto a roll R and a control unit 105 configured to independently control at least each unwinding device 101, 102, the sealer 104 and/or the winding device 104. The system 100 further comprises multiple guide rollers G. One guide roller G is positioned between the unwinding devices 101, 102 and the sealer 103 and is configured to guide packaging material 111, 112 towards the sealer 103. In the figures, it can be seen that the method according to the present invention is preformed. The arrows in the figures indicate the direction of movement of the packaging materials 110, 111, 112 during the production of a roll multi-layered packaging material 110. Before the first and second packaging materials 111, 112 reach the sealing device 103, they are guided towards a parallel configuration. It can be seen that the first packaging material 111 and the second packaging material 112 enclose a predetermined angle a prior to being guided towards the parallel configuration. it will be clear that the invention is not limited to the exemplary embodiments which are illustrated and described here, but that countless variants are possible within the framework of the attached claims, which will be obvious to the person skilled in the art.
