Definitions
- the invention relates to the technical sector of labels for plastic containers or packaging.
- the invention relates to an IML tag, the acronym for In Mold Labeling.
- IML label is included in a package at the time of manufacture.
- the label and packaging are fused during the injection molding process or by thermoforming or blowing.
- the label, previously printed, is placed in the mold just before the injection (or thermoforming or blowing), which allows to incorporate it into the packaging material.
- This in-mold labeling process offers many advantages. It is not described in detail because it is well known to a person skilled in the art.
- the label is generally made from a polypropylene film, and is, as indicated, embedded in the package by partial melting of its inner face in particular, with the aim of ensuring the decoration of the whole or of some of the packaging.
- the labels used are completely smooth, so that the external visual appearance of the container incorporating this IML label will also have a totally smooth effect.
- the surface of the label after injection or thermoforming of an EUH / EPT expanded material, the surface of the label has an orange peel effect.
- the problem to be solved by the invention is to produce a touch-sensitive IML label, such as a raised paper effect according to different geometric shapes.
- a touch-sensitive IML label such as a raised paper effect according to different geometric shapes.
- the invention for producing, from a polypropylene film, an IML label with tactile effect, it has been conceived and developed a method according to which, after subjecting the film to a decoration by any type of printing process perfectly known to a person skilled in the art, such as gravure printing, flexography or offset, according to different successive steps depending on the desired number of colors:
- the film is subjected to a cylinder having an intaglio engraving capable of receiving a varnish with a tactile effect, or to an anilox / cliché combination capable of receiving a varnish with a tactile effect,
- the touch-sensitive varnish is printed with the cylinder or with the cliché on the film
- an IML protection varnish for injection or thermoforming or blowing of a plastic material
- the film is cut to obtain the touch-sensitive IML labels.
- the protective varnish will be deposited or not depending on the need of the following process. It may be deposited before or after the touch-sensitive varnish. It follows from these characteristics, that the IML label has directly, and before integration into the package, a tactile effect resulting in particular from the engraving hollow cylinder, or the combination anilox / cliche, in combination with the specific varnish . This tactile effect will be found, for example inversely (the reliefs become hollows), at the level of the packaging presenting this IML label.
- said cylinder is tempered in a tray containing the touch-sensitive varnish, and subjected the cylinder to a wiping operation so that said varnish remains only in the hollow forms of the etching.
- FIG. 1 is a purely schematic view, showing an example of a gravure installation for implementing the method according to the invention.
- FIG. 2 shows an IML label board, obtained according to the invention
- FIG. 3 is a front view of an IML label with tactile effect, before being placed in the mold
- FIG. 4 is a view of an example of a container, equipped with a touch-sensitive IML label, according to the characteristics of the invention.
- the IML label (1) is produced, for example, from a polypropylene film, with a thickness of between 30 and 80 ⁇ m, with a density of approximately 550 kg per m 3 . Note that any material adapted to the IML may be used.
- the polypropylene or other film such as PS or PET (1), for producing the various labels is printed by any type of process perfectly known to a person skilled in the art, in particular by gravure or flexography.
- FIG. 1 shows a purely schematic installation for printing by the gravure printing process of a film (1) for producing the IML labels (1).
- the film (1) is subjected to the action of an unwinding device (2) to be transferred to different positions (A) - (B) - (C) - (D) - (E) ) - (F) -, each corresponding to a color.
- Each station has an ink tank (3), a cylinder (4) and a gripping cylinder (5) between which the polypropylene film (1) passes. Between each station is a hot air dryer (6).
- FIG. 1 After having thus subjected the film (1) to the gravure printing process, FIG. 1, according to the different positions (A) - (B) - (C) - (D) - (E) - ( F), the film is subjected to a cylinder (7), having an intaglio engraving, able to receive a varnish with tactile effect, which corresponds to the station (G) of FIG.
- the aim is therefore to print the tactile effect varnish with the cylinder (7) on the film (1).
- the cylinder (7) may have 100 lines per centimeter, with a depth of about 160 ⁇ .
- an IML protection varnish is printed on the film (1), to allow, later, the injection, the thermoforming or the blowing of a plastic material. (Station H, Figure 1) for packaging to achieve.
- the protective coating provides the film and the tactile varnish with a temperature resistance, and also gives antistatic properties.
- This type of varnish is well known to a person skilled in the art, in the case of an IML label.
- This varnish can also be printed before the tactile varnish (post G), the tactile varnish is printed at station H, or not printed at all, depending on the need of the process.
- FIG. 3 shows an IML label (1), resulting from the characteristics of the method according to the invention, which has recessed (1a) and raised (1b) zones, for example giving a raised paper effect, and consequently , a tactile effect.
- FIG. 4 shows an example given by way of indication, in no way limiting, of a package incorporating the IML label (1), according to the invention.
- the invention thus makes it possible to obtain a tactile IML label, that is to say having areas in relief, which is intended to be integrated in a package to give it a tactile effect.
