Abstract

The base film (2) is orientated polypropylene, preferably bi-axially orientated polypropylene or polyethylene terephthalate. To the metallized side (3), a printed layer (5) is applied. On the opposite side a cold adhesive (6) is applied sparingly, preferably in strip form.

Description

Description
Plastic film
The invention relates to a plastic film, especially for packaging three-dimensionalobjects such as soup cubes in particular, with a base film made from a polyolefin orpolyethylene terephthalate that is preferably metallised on one side. DE-A-199 48 286 discloses a plastic film, particularly for packaging preferably cube-shaped products such as soup cubes, where the plastic film consists of a polyolefinfilm, preferably PE or PP.
On the basis of this, the aim of the invention is to design a plastic film of the kindoutlined above in such a way that simple packaging of the objects and largely airtightclosure of them is guaranteed.
In the solution to this problem proposed by the invention, an oriented polypropylenefilm, preferably a biaxially oriented polypropylene film or a PET film, is provided asthe base film, on one side of which, preferably the side with the métallisation, printing 0124 1 1 2 is provided, to which in tum a pattern coating of a sealing lacquer that seals at a raised température is applied.
Polypropylene film oriented in one direction or biaxially and PET film hâve very goodtightness properties, which are improved even more by the addition of métallisation onone side.
The pattern coated sealing lacquer permits tight closure of a pack made from thisplastic film that is folded around the object, with the pattern application making surethat only as much sealing lacquer is used as is necessary for closing purposes.
In accordance with an advantageous further development of the invention, the areas ofthe printing and / or métallisation to which the sealing lacquer is not applied areprovided with an overlacquer that is also pattern coated.
This means that these areas of the print motif and / or the métallisation in addition tothose coated with the sealing lacquer are protected and the thickness of the filmremains consistent across its entire width, so that even winding of the film is possible.
In another advantageous further development of the invention, a primer and / or tielayer is provided between the métallisation and the printing.
It has proved to be very advantageous if in accordance with another advantageousfurther development of the invention a compact film is provided as the base film. A film with cavities in it can, however, be provided as the base film in accordancewith the invention too. 012411 3
Both types of film hâve proved to be very effective in this context, with the film with cavities in it appearing to be largely opaque, because light refraction occurs at the edges of the cavities.
The cavities can take the form of vacuoles that are produced when the film is oriented.
It is, however, also possible to produce the cavities by foaming.
If a compact base film is used, a thickness of about 10 to 100 μ, preferably 20 to 50 μand in particular 28 to 32 μ is provided for this film in accordance with the invention.
If a base film with cavities is used on the other hand, a thickness of about 10 to 100 μ,preferably 20 to 50 μ and in particular 35 to 40 μ has proved to be advantageous.
It is provided in another advantageous further development of the invention that theside of the base film facing away from the printing that is located preferably on theinside is provided with at least one further layer.
One embodiment of the invention is illustrated in the drawings:
Fig. 1 is a diagrammatic cross section of a film structure with a clear film and
Fig. 2 is a diagrammatic cross section of another film structure with an opaquefilm. 1 in Fig. 1 is a plastic film that has a base film 2 which consists of orientedpolyproplyene (OPP). The orientation can be carried out either in one direction orbiaxially. This base film 2 is provided with métallisation 3 on one side. To improvebonding, the métallisation 3 is provided on its side facing away from the base film 2 4 0/24) ) with a primer layer 4, to which in tum printing 5 is applied. A pattern coating of a sealing lacquer 6 that seals at a raised température is applied to this printing 5, with the sections to which this sealing lacquer 6 is not applied being provided with an overlacquer 7. A thickness of 30 μ has proved to be effective for the base film 2 made from orientedpolypropylene (OPP). The areas to which the sealing lacquer 6 are applied arearranged in such a way that tight closures can be produced when a section of theplastic film 1 is folded up around a three-dimensional object that is not illustrated.
The main différence in the embodiment of a plastic film 21 as shown in Fig. 2 is thatan opaque and oriented polypropylene film (OPP) with a thickness of 38 μ is used asthe base film 22.
The opacity of the base film is produced during orientation, when vacuoles are formedin the film and cause réfraction of light.
The cavities can, however, also be produced by foaming the film.
The base film 22 has métallisation 3 in this case as well, to which printing 5 has beenapplied via a primer layer 4. A pattern coating of sealing lacquer 6 is applied to thisprinting 5 too, so that this lacquer is only présent at the places needed to form andclose a pack. The remaining sections are again provided with an overlacquer 7.
An application thickness of 1 to 5 g/m2 is specified for the overlacquer 7; this thicknesscan vary between 0.1 and 15 g/m2 according to requirements and is adapted to thethickness of the sealing lacquer 6 that is applied.
5
The side of the base film 22 facing away from the métallisation can - as the illustrationshows - be provided with another coating 8, in order to achieve further barrierproperties. A PET film can be used as the base film instead of a polypropylene film.
