Detailed description

A label is attached to a baggage in order to enable safe and secure transportation and identification of the baggage. A label for a baggage is printable. A label is printed with travel and identification information at a check-in. This may be done at a check-in desk or at a check-in kiosk, of which the latter enables self-service by a traveller. Due to increasing self-services and different users, ease of use of the printed labels is a desired factor. The printed labels should be attached properly in order for those to sustain transportation and handling. A possibility of a traveller to attach a label to their baggage improperly may affect fastening and thereby proper permanent attachment of the label. If a label is attached improperly, for example adjustment of the two attached portions of the label is not properly facing next to each other, adhesive may remain exposed. This leaves the attaching surface partly unused, which may have effect on fastening strength. Further, the exposed adhesive may stick to another object, which may pose tearing forces to the label.
The label itself and its attachment to itself have strength, stiffness and stability in order to sustain use, wear and handling. The printed label enables automated, machine reading of the information in order to automate baggage processes and management. This machine readable information is saved in the logistic system in order to enable tracking of baggage. Typically, this information is first created at a check-in desk or baggage drop, when the baggage is handed over to be transported. Then, this information is read or scanned later at several occasions during transportation of the baggage through the logistics and to its final destination. The attached printed label sustains external conditions when the baggage is transferred along conveyor belts and is loaded to various vehicles, for example an aircraft and unloaded from the vehicles. The attached printed label sustains baggage process handling and enables automatic reading or scanning, as well as human visual identification by travellers at a carousel after a flight.
Figure 1 illustrates a label seen on a side. A label comprises a face material 101, an adhesive 102 and a release liner 103. The underside of the face material 101 is at least partly covered with adhesive 102. The liner 103 may be arranged with a release layer as a coating. The liner 103 may be, for example, siliconized. A release layer, such as a silicone side of the liner 103, is facing the adhesive side of the face material 101.
A face material may be a paper based, a plastic film or a combination of these. A paper based face material may comprise glassine or kraft paper, for example. The plastic film may comprise polymers, such as polyolefin, polyester, polystyrene, polyurethane, polyamide, polyvinylchloride or any combinations of these. The face material may be biodegradable, such as lactic acid, starch or cellulose based. The polymer film may include homopolymers, copolymers or it may consists of a polymer blend. For example, the face material may comprise mixtures of polyolefins, such as polyethylene (PE) and polypropylene (PP). In addition, the plastic film may comprise additives, such as pigments or inorganic fillers to provide, for example, a desired colour for the face. Additives may include, for example, titanium dioxide, calcium carbonate and blends thereof. The plastic film may comprise minor amounts of other additives and/or film modifiers, e.g. plasticisers, stabilizers, anti-static agents, slip/anti-block agents. The face may be coated. The face material may be arranged to be thermally printable, for example, by use of a thermally printable coating on the face material. The face material may have other or alternative coating layers to enhance its physical, visual or printability properties.
The face material comprises two surface sides. One of the surface sides of the face material, a backside, is able to receive adhesive. The face material is compatible with adhesive. Anchorage between the face and adhesive is desired. Adhesive migration on the face surface is not desired. The face material and adhesive shall have no harmful reaction(s) between the two.
Another face material side, a front side, opposing the side arranged to receive adhesive, is printable. Properties of the face material have effect on printing and/or print quality, for example on density levels of ink/toner, bleeding of ink/toner, ink/toner transfer and anchorage. The face paper absorption properties, surface properties, surface chemistry, surface porosity may have effect on printing and print quality. The surface suitable for printing has a sufficiently high surface tension. A low surface tension may lead to poor retaining capability of printing ink/toner applied to the surface.
For example, a plastic film as face material, may be printable with printing inks using for example offset, flexography and/or digital printing. A printable plastic film may have a surface tension at least 36 dynes/cm, preferably at least 38 dynes/cm or at least 44 dynes/cm measured according to the standard ASTM D-2578. The surface tension may be between 36 and 60 dynes/cm, preferably between 38 and 56 dynes/cm or between 44 and 50 dynes/cm.
A face material may be printable via thermal printing, for example via direct thermal printing. The face material is suitable for thermal printing and thermal print transfer. The face material may comprise a thermal coating at both sides or least on one side for receiving a print. The face material may be a thermal paper comprising thermal coating layer(s). Thermal coating layer is thermally active and able to provide printability for the thermal paper. The face material smoothness has effect on providing suitable and even contact between print ink and the face material. The face material absorption properties have effect on anchorage of the ink.
In an example, the face material may be a top coated paper with a thermal coating. Alternatively, the face material may be a non-top coated paper with a thermal coating. The face material comprises roughness equal or less than 2.3 µm, for example 1.9 µm, according to ISO 8791-4.
The label laminate comprising the face material, pressure sensitive adhesive and release liner laminated together are manufactured as a continuous web which is cut lengthwise to narrower width customer rolls, where the width of the web corresponds to the width of the labels in the end use. This lengthwise cutting process is called slitting. Before its final use at variable information printing machines, for example at the airport, the label laminate is typically further converted either before or after slitting, in other words as wider width or as customer width web format. Such converting phase may include providing further coatings on the laminate, adding constant printing such as brand markings or colours and finally die-cutting the web into individual labels on the liner and/or providing the laminate with required cuts/perforations in the face and/or liner materials. The final printing of the variable part of the information, i.e. the machine and/or human readable traveller specific information takes place at the check in or baggage drop printer onto such converted label web.
Depending on the variable information printer, which is typically a direct thermal printer, the printer may include means to cut the converted web lengthwise, or the lengthwise separation may be achieved through perforations/cuts prepared into the web already during the earlier converting phases.
According to the invention, the face material is die-cut at least from the liner side to allow separation a part of the liner from the face material to facilitate the use of the label as a luggage tag adhered onto itself. The liner is die-cut in order to enable removing the liner partly, or separating the liner from the adhesive face material. Die-cutting of the liner made such that desired part of the liner at a predetermined area and length is easily separable from the face material. Since the die-cutting is implemented on the liner side, the face material comprises properties for enabling its function as a die-cutting underlayer. Density and uniform thickness of the face layer may enable die-cutting the release without affecting appearance or dimensions of the face material.
In an example, the face material comprises density of between 50 and 120 g/m², for example from 55 to 86 g/m², when measured according to ISO 536.
In an example, the face material comprises thickness of 10-120 µm, or 30-90 µm, for example 72 µm or 79 µm, according to ISO 534.
In an example, the face material for a baggage label comprises tensile strength in the machine direction MD of at least 3 kN/m, for example at least 3.3 kN/m or at least 3.9 kN/m; and in the cross direction CD at least 1.5 kN/m or at least 1.9 kN/m, when measured in accordance to the standard ISO 1924.
The face material for a baggage label comprises tear strength of between 300 and 450 mN, for example between 350 and 380 mN, or for example 400 mN according to ISO 1974.
The face material may comprise roughness (PPS 10) of 1.9 µm, 1.7 or 1.4 according to ISO 8791-4.
A release liner comprises a carrier layer or substrate, also referred to as a backing material, which is coated with a release agent. A liner comprising a backing and a release agent coating provides the nonadherent surface and low adhesion release effect against the adhesive. A release agent may comprise silicone- and/or fluoro- based materials. A release agent may be surface coated on a surface(s) of a backing of the liner. The release layer is provided on a substrate surface of the liner in order to enable releasable attaching of the liner surface to adhesive side of the face material. A release agent may be provided on both sides of the substrate of the liner. As an example, release coating may consist mainly of cross-linked silicone. The cross-linked silicone has poly dimethyl siloxane network PDMS (Me₂SiO)_n. As an example, release coating may consist of fluorosilicone or fluorocarbon. A release agent coated on a substrate surface may have effect of providing smooth liner surface. It may also have effect on low release force required to separate the adhesive from the liner so as to avoid tearing of the label structure. A release agent may comprise coat weight of 0.1-2 g/m², or between 0.5 and 1.5 g/m² (dry grammage).
A liner may comprise a paper or a plastic film as a substrate, for example polyethylene, polypropylene or polyester. The liner substrate may comprise or consist of polyethylene terephthalate (PET). PET as a substrate of the liner may have effect on easy cutting allowing extended service life of a cutter, such as knife cutter of the self-service check-in printing apparatus. A liner comprising a plastic film substrate has effect on smoothness of the surface. For example, an uncoated paper substrate may comprise less smoothness on the surface compared to a plastic film substrate. Smooth surface of a plastic substrate may have effect on clarity of the liner itself. In addition, smooth liner substrate surface may also have effect on helping to create a smooth and constant thickness of the adhesive layer subsequently provided on the liner surface. A transparent liner enables providing a print on both liner surface, or on both face material surfaces. A transparent liner may enable providing a visible print on a face surface or on a liner surface arranged next to each other, or on an adhesive. A plastic liner comprise good mechanical properties having positive effect on strength. This provides strength and wear sustainability for the label, since the liner is not removed, but left between attached ends of the label. A liner protects adhesive layer during shipment and storage. A liner enables a label web to be rolled on a roll.
The liner substrate may comprise or consist of recycled material, like recycled polyethylene terephthalate (PET).
The PET based liner may have thickness of between 10 and 40 µm or between 15 and 36 µm, for example 19, 23, 30 or 36 µm. The paper based liner may have thickness between 40 and 75 µm.
In an example, the liner comprises basis weight of equal or less than 76 g/m² in accordance to ISO 536. The PET based liner has a basis weight of 32 or 42 g/m² in accordance to ISO 536.
The liner is die-cuttable. The liner comprises suitable tensile and tear strength in order to be die-cuttable.
The PET based liner comprises tensile strength of 150-210 kN/m in MD and 200-270 kN/m in CD in accordance to ISO 1924-2. In an example, the liner comprises tear resistance of 220-330 mN in machine direction MD and 250-350 mN in cross direction CD.
An adhesive may comprise a pressure sensitive adhesive (PSA), also known as a self-stick adhesive. A PSA forms a bond when pressure is applied at room temperature. PSA enables a label to be adhered to a surface through an adhesive layer without the use of a secondary agent such as solvents or heat to strengthen the bond. The PSA forms a bond when pressure is applied onto the label at room temperature, adhering the label to the item to be labelled. In an example, the adhesive layer includes solid PSA (also referred to as hot melt PSA). The PSA may be, for example, acrylic or rubber based. An adhesive has a tack of at least 10 N or 12 N in accordance to Finat test method FTM 9. The adhesive may exhibit tack of between 10 and 25 N.
Figure 2a illustrates a label web for a baggage on a front side, or on a face side. The label web comprises subsequent labels 201a on a face side. Labels may comprise a rectangular form having longitudinal edges and shorter transverse edges. Each label 201a may comprise a perforated area 203a, which enables gripping and removing the face area with a liner portion, when separating a liner portion from adhesive face. The label web comprises perforations 202, which enable to separate the labels from each other. The perforations penetrate the label, via the face and the liner, in order to enable separation of individual labels from each other. The face is printable. Thermal printing, UV-flexography, water-based flexography or UV-letterpress printing may be applied. The face may comprise pre-printed information, like colour or data. The information to be printed on the face material may be in form of codes, like bar codes. In addition a backside of a face material may comprise a print. For example, user instructions for using a label for a baggage, or other data, may be printed on a backside of a face. Transparent adhesive on a print and a transparent liner enable data, like user instructions, printed on a backside of a face to be visible for a user. Alternatively, an adhesive on a backside of a face may be printed, for example with user instructions or other data. A transparent liner enables visibility of the print and may protect the printed information on adhesive or on backside of a face.
Figure 2b illustrates a label web for a baggage on a back side, or on a liner side. The label web comprises subsequent labels on a liner side 201b. The label web comprises perforations 202, which enable to separate individual labels 201b from each other. The perforations penetrate the label, via the face and the liner, in order to enable separation of individual labels from each other. The liner comprises a die-cut for a portion of the liner that is to be separated from the adhesive face. The printed instructions 203b may indicate to a user, where to start the separation of the liner from the adhesive face. The instructions may comprise a text, for example "open here". The liner area, which is arranged to be separated from the adhesive face, is die-cut in order to direct and control separation. The die-cut area is arranged to indicate a predetermined detachment area of the liner. The liner separation may start along a transverse edge line of a label AA. A die-cut area 203a on a face side, as illustrated in Fig. 2a, may be gripped by a user and remain attached to the liner side, when separated. The die-cut area 203a on a face side may enable easy and controlled start for separation of the predetermined liner area. Separation is directed along die-cut lines 204 along longitudinal edges of the liner. Die-cut lines 204 are arranged parallel to the longitudinal edges. The die-cut lines 204 provide on a liner side a longitudinal edge area for which an adhesive is not exposed. The non-exposed area, at which the liner is arranged to be attached to the adhesive face side, may comprise 5-30 mm, or 5-20 mm on each longitudinal side of the label. The non-exposed area may comprise, for example, 5-10% of the label width along transverse direction AA of the label. The non-exposed edges have effect of reducing accuracy of adjustment of the attachment of the label. Thus, some variation is allowed without exposing adhesive. This provides more easy and handy use and attachment of the label to a baggage.
Die-cutting 204 is applied via longitudinal edges in order to guide and direct the separation of a predetermined area of the liner. Instead or in addition to a stop sign for user arranged to indicate the place, where the separation of the liner from the adhesive face is to be stopped, a die-cut 204b is utilized. Die-cutting 204 along longitudinal edges is arranged to curve 204b towards or away from longitudinal edge portion of the liner. This has effect of providing tactile feedback for a user, when a liner is separated. Just ending straight die-cut 204 along longitudinal edge of a liner may lead to separating the liner beyond the predetermined or desired separation area. Or a continuing separation force, pulling a liner away from an adhesive face, may tear a liner. Curved 204b or alike die-cut portion changes direction of separation, which poses tactile feedback to a user separating the liner portion. This has effect on usability of the label and/or providing sign for stopping the separation to a user. This enables handy, proper and safe use among different users.
Figures 2c and 2d illustrate labels according to embodiments. The Figs. 2c and 2d illustrate alternative ways of die-cutting the liner 201b in order to guide and direct separation of the predetermined liner area for the adhesive face. A longitudinal edge of the liner is left attached to the adhesive face by providing a die-cut line 204 for separating the liners 201b. The width of the attached edge portion next to the attachable liner portion may differ. Fig. 2d shows a die-cut line 204 on the longitudinal edge portion, which is extends in angled manner compared to the straight longitudinal edge of the liner 201b. Distance between the die-cut 204 and the longitudinal edge of the liner 201b or label increases, while the die-cut 204 extends from the transverse edge of the liner 201b or the label. Die-cut 204b, which is arranged to indicate end of detachment portion of the liner 201b, is implemented by separate adjacent lines 204b in Fig. 2c. In Fig. 2d corresponding die-cut 204b is implemented by angled pattern, like a zigzag. Other implementation possibilities are possible. A die-cut arranged to indicate end of a detachment area of a liner may comprise different kind of forms. The die-cut 204b is arranged to differ from a previous line (204) of separation. The die-cut 204b may be implemented as a line, as a curved line, as a separate lines or via perforations. A die-cut 204b may be arranged along a transverse line of a predetermined area of detachment of the liner 201b. A die-cut 204b implemented at edge areas of the liner 201b, instead of the transverse line along liner width, may have effect of avoiding any weakening effect of the label strength and/or less die-cutting. For example any inaccuracy of depth of die-cutting, which may be due to wear of cutting/punching die or machinery, has effect on face strength and stability, which is underlaying the die-cut liner.
In Figures 2a-d the liner separation may start along a transverse edge line of a label AA. Alternatively, liner separation may start along a transverse line, which is arranged parallel with the transverse edge line of the label AA and separated from the transverse edge line of the label AA, optionally a certain distance.
Figure 3a illustrates a label according to an embodiment. A portion of a liner 303 is detached at a predetermined area. The predetermined area includes a middle area of the liner between the die-cut edge portions along the longitudinal edges and the die cut indications at the end of the predetermined detachment area. The middle area of the liner in the transverse width direction is free of die-cut. The longitudinal edge area of the liner 304 is left attached to the face 301. The detached liner portion exposes adhesive 302 on the surface of the face 301. The predetermined area of the liner 303 is detached from the adhesive face 301. The detachment or separation is stopped at a correct place. The curved die-cut of the liner 303 has effect of providing feedback for a correct place to stop detachment or separation of the liner 303. This enhances userfriendly separation of the liner 303 with our without printed instructions indicating end of detachment portion. The opposing, unexposed portion of the face 301 is arranged to be attached to the corresponding opposing edge area 305 at the other longitudinal end of the label via the exposed adhesive 302. The detached liner portion 303 remains fixed in the label. No additional waste is created. The liner 303, optionally a PET liner, may provide stiffness and tear strength for the label.
In Figure 3a, the longitudinal edge area of the liner 304 is left attached to the face 301. In addition, the liner 304 may be left attached to the face 301 at a transverse end of the face 301, opposing edge area 305. The liner 304 may be die-cut such that the die-cut detachment line in the transverse width direction of the longitudinal label is separated from transverse edge line, being the longitudinal end, of the label. An edge area comprising liner 304 attached to the face 301 may be provided around the detachable liner 304, along longitudinal and transverse edge areas of the label. This may provide gripping area, which may aid in detaching the liner, attaching exposed adhesive area to the label and detaching the label attached to itself. In addition or alternatively, exposed adhesive are may be attached to the opposing edge area 305 such that the face 301 with exposed adhesive portion is attached at a distance from the outmost edge area 305, leaving an external transverse edge, at a longitudinal end of area 305, free of adhesively (302) attached face.
Figure 3b illustrates an attached label according to an embodiment. The label 311 is attached around a handle 310 of a baggage. The liner of the label 311 is detached from a predetermined area, the label 311 is placed around the handle 310 and the opposing longitudinal edge of the label 311 is attached next to the exposed adhesive, at the same, liner side of the label 311. The attached portion of the face 312 comprises printed identification information. The strength of attachment is provided by predetermined attachment area and adhesive. User-friendliness is provided by tolerance for adjusting the edge portions next to each other. Even if adjustment is not exact, adhesive is not exposed due to non-adhesive edge portions. This provides reliability for the label, when use is made less user-dependent. The label comprises strength and stiffness. The liner has effect of providing stiffness to the construction.
Web of labels may be rolled to a roll. A label web may comprise, on a transverse direction of a label web, a width of 30-80 mm, even up to 130 mm. A label roll comprises a diameter suitable for a printing machine at a check-in. Number of labels on a roll is dependent on label size. Length of a label may be varied to a certain amount only, keeping in mind that handy and reliable a self-service use is enabled.
It is desired to provide a thin construction providing a label with suitable and/or reliable strength and stiffness properties in order to be usable for baggage. A label may comprise a film face and a liner. The film face material may comprise thickness of 30 - 90 µm, for example 72 µm or 79 µm, and a liner may comprise thickness of 15-45 µm, for example 19, 23 or 30 µm. This may enable reducing thickness of a label 20-50%.
A label of reduced thickness is ecological in material use and saves material costs. A thin construction enables providing more labels by same weight. This has effect on logistics and storage space. A label web may be rolled to a roll. A thin construction of a label web enables more labels to be included to a single roll. This enables increasing number of labels provided between replacing a used roll with a new one. This has effect on personnel time for service at checkins.
An arrangement for providing a label for a baggage comprises a printer for printing a label. A label roll is insertable to the arrangement for providing a printed label. The arrangement may comprise a check-in printing machine. A label roll is applicable for a check-in printing machine. A print is provided on a face in accordance to the inputted information at a check-in. For example a bar code enabling automatic reading, scanning and storing of read data provides efficiency to a baggage management. The printer may be a thermal printer.
