Abstract
Plastic film (1, 21), especially for packaging rectangular objects such as stock cubes, comprising a base film (preferably metallised on one side) consisting of biaxially oriented polypropylene film or polyethylene terephthalate film with printing (5) (preferably on the metallised layer (3)) and an outer layer of heat-sealing varnish (6) in the appropriate places.
Description
PLASTIC FILM The invention relates to a plastic film, especially for packaging three-dimensional objects such as soup cubes in particular, with a base film made from a polyolefin or polyethylene terephthalate that is preferably metallised on one side.
It is to be noted that only subject matter embraced in the scope of the claims appended hereto, whether in the manner defined in the claims or in a manner similar thereto and involving the main features as defined in the claims, is intended to be included in the scope of the present invention, while subject matter described and exemplified to provide background and better understanding of the invention, is not intended for inclusions as part of the present invention.
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 polyolefin film, preferably PE or PP.
On the basis of this, the aim of the invention is to design a plastic film of the kind outlined above in such a way that simple packaging of the objects and largely airtight closure of them is guaranteed..
According to the present invention there is now provided a plastic film, especially for packaging three-dimensional objects such as soup cubes in particular, with a base film made from a polyolefin or polyethylene terephthalate that is preferably metallised on one side, whereby an oriented polypropylene film, preferably a biaxially oriented polypropylene film or a PET film, is provided as the base film, on one side of which, preferably the side with the metallisation, printing is provided, to which in turn a pattern coating of a sealing lacquer that seals at a raised temperature is applied, wherein the areas of the printing to which the sealing lacquer is not applied are provided with an overlacquer that is also pattern coated.
In the solution to this problem proposed by the invention, an oriented polypropylene film preferably a biaxially oriented polypropylene film or a PET film, is provided as the base film, on the side of which, preferably the side with the metallisation, printing is provided, to which in turn a pattern coating of a sealing lacquer that seals at a raised temperature is applied.
Polypropylene film oriented in one direction or biaxially and PET film have very good tightness properties, which are improved even more by the addition of metallisation on one side.
The pattern coated sealing lacquer permits tight closure of a pack made from this plastic film that is folded around the object, with the pattern application making sure that only as much sealing lacquer is used as is necessary for closing puiposes.
In accordance with an advantageous further development of the invention, the areas of the printing and / or metallisation to which the sealing lacquer is not applied are provided with an overlacquer that is also pattern coated.
This means that these areas of the print motif and / or the metallisation in addition to those coated with the sealing lacquer are protected and the thickness of the film remains 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 tie layer is provided between the metallisation and the printing.
It has proved to be very advantageous if in accordance with another advantageous further 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 accordance with the invention too.
Both types of film have 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 μ _ and 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 the side of the base film facing away from the printing that is located preferably on the inside 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 opaque film. 1 in Fig. 1 is a plastic film that has a base film 2 which consists of oriented polyproplyene (OPP). The orientation can be earned out either in one direction or biaxially. This base film 2 is provided with metallisation 3 on one side. To improve bonding, the metallisation 3 is provided on its side facing away from the base film 2 with a primer layer 4, to which in turn printing 5 is applied. A pattern coating of a sealing lacquer 6 that seals at a raised temperature 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 oriented polypropylene (OPP). The areas to which the sealing lacquer 6 are applied are arranged in such a way that tight closures can be produced when a section of the plastic film 1 is folded up around a three-dimensional object that is not illustrated.
The main difference in the embodiment of a plastic film 21 as shown in Fig. 2 is that an opaque and oriented polypropylene film (OPP) with a thickness of 38 μ is used as the base film 22.
The opacity of the base film is produced during orientation, when vacuoles are formed in the film and cause refraction of light.
The cavities can, however, also be produced by foaming the film.
The base film 22 has metallisation 3 in this case as well, to which printing 5 has been applied via a primer layer 4. A partem coating of sealing lacquer 6 is applied to this printing 5 too, so that this lacquer is only present at the places needed to form and close 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 thickness can vary between 0.1 and 15 g/m2 according to requirements and is adapted to the thickness of the sealing lacquer 6 that is applied.
The side of the base film 22 facing away from the metallisation can - as the illustration shows - be provided with another coating 8, in order to achieve further barrier properties.
A PET film can be used as the base film instead of a polypropylene film.
