Wrapping material for packaged goods and stack, comprising a plurality of
these
wrapping materials, as well as use of the wrapping material
Description
The present invention relates to a wrapping material for packaged goods,
preferably for a
foodstuff, particularly preferably for a fast-food foodstuff. Furthermore, the
invention relates
to a stack comprising a plurality of wrapping materials according to the
invention. Moreover,
the invention relates to the use of the wrapping material according to the
invention for the
packaging of foodstuffs.
Wrapping papers for foodstuffs have been in use for a long time both in the
private and in the
commercial field, for example in order to wrap foodstuffs such as cheese or
sausage.
Wrapping papers are accordingly regularly found in butcher shops and
delicatessen and fish
shops. These wrapping papers are usually configured to be grease-resistant. In
the case of
the mentioned wrapping papers, these have to be adapted in size and format to
the foodstuff
to be packaged.
In contrast, up to now folded boxes made of paper or cardboard have usually
been used for
the packaging of ready-to-eat cooked or warmed-up foodstuffs such as burgers
or pizzas.
Such packages are adapted in size to the foodstuff to be packaged. Their
production is
complicated in terms of production technology and not seldom material-
intensive. Such
product packaging also sometimes have viewing windows made of plastic film. As
a result,
a pure-grade recycling is made difficult or impossible.
It would be desirable to be able to use wrapping papers which are
distinguished by a very
broad range of applications. Therefore, the object of the present invention
was to make
available wrapping papers which are not affected by the disadvantages of the
prior art and
Date Re cue/Date Received 2023-10-13
which in particular allow a complication-free wrapping of any ready-to-eat
foodstuffs and
dishes.
Accordingly, a wrapping material for packaged goods, preferably for a
foodstuff, and
particularly preferably for a fast-food foodstuff, was found, comprising
i) a wrapping film or a wrapping paper, in particular a wrapping paper,
having an inner
side and an outer side facing away from the inner side, a first edge and an
opposite
second edge as well as mutually opposite first side edges and second side
edges,
which extend from the first edge up to the second edge, and
ii) a
material strip, in particular a sleeve, present on the outer side of the
wrapping film
or of the wrapping paper, in particular of the wrapping paper, having a first
end and
an opposite second end, which extends starting with the first end from the
first edge
or spaced apart from the first edge to the second edge or in the direction of
the second
edge,
wherein the wrapping film or the wrapping paper, in particular the wrapping
paper,
has a folding or crease line extending from the first side edge or spaced
apart from
the first side edge up to the opposite side edge or in the direction of the
second side
edge, which is spaced closer to the first edge than to the second edge.
Due to the fact that the folding or crease line has to lie closer to the first
edge than to the
second edge of the wrapping film or of the wrapping paper, this wrapping film
or this wrapping
paper is divided into a shorter first section and a longer second section.
Hereby, this first
section regularly has a smaller area than the second section.
In the sense of the invention, a crease is to be present when it has been
produced with the
aid of a tool provided for this purpose or a machine provided for this
purpose. Such
mechanically produced creases are regularly configured in the form of a kinked
edge. If such
a kinked edge is produced without the aid of a tool, a fold is to be
understood in the sense of
the invention. The fold or crease is preferably attached to the inner side of
the wrapping film
or of the wrapping paper, in particular of the wrapping paper, or is present
on this inner side.
The inner side in the sense of the invention is to be understood as that side
which faces away
from the material strip or the sleeve.
By providing the wrapping film, in particular the wrapping paper, with a
material strip, in
particular with a sleeve, this can have a neutral appearance, while the
material strip can be

Date Re cue/Date Received 2023-10-13
printed or otherwise configured. Due to the fact that the wrapping film, in
particular the
wrapping paper, of the wrapping material according to the invention does not
have to be
printed or colored, no special format specifications are regularly to be
observed with regard
to the wrapping film or the wrapping paper. In order to give the wrapping
material according
to the invention a characteristic impression, it is sufficient to resort to a
colored or printed
material strip. This can be produced separately and attached to the wrapping
film or the
wrapping paper after completion. This procedure enables flexible production of
multifaceted
material strips coupled with simple stocking of a comprehensible selection of
wrapping films
or wrapping papers.
Due to printing technology, a narrow edge region often remains unprinted or
white at one
end of the material strip or the sleeve, i.e. in the color of the base
material of the material
strip. The side of the material strip, in particular of the sleeve, printed
incompletely in this way
is selected according to the invention such that it is present in a section at
or in the region of
the first end of the material strip or the sleeve. Accordingly, it can
preferably be provided that
the printed side of the material strip, in particular of the sleeve, is
unprinted or white in a
section at or in the region of the first end. According to the teaching of the
present invention,
it is provided that the second end of the material strip coincides with the
second edge of the
wrapping paper or the wrapping film or that the second end of the material
strip and the
second edge of the wrapping paper or the wrapping film are aligned
identically. In interaction
with the folding or crease line, it is ensured in this way that the unprinted
or white region is
always covered by the material of the wrapping paper or the wrapping film
during wrapping
or packaging of the packaged goods, in particular of the foodstuff. This is
because, by
providing a folding or crease line, which is additionally present closer to
the first edge than to
the second edge of the wrapping paper or the wrapping film, the packaged
goods, e.g. a
burger, is placed on the longer or larger-area second section of the wrapping
paper or the
wrapping film adjacent to the folding or crease line. Hereby, the second
section is placed or
wound over the shorter first section lying at the bottom. The packaged product
thus always
has an immaculate, flawless appearance. Thus, the appreciation of the packaged
product is
no longer affected by packaging that is not completely immaculate.
In an expedient embodiment, the wrapping film of the wrapping material
according to the
invention constitutes a plastic film or is substantially made thereof.
Preferably, the wrapping
paper is selected from the group consisting of parchment paper, parchment
substitute paper,
grease-proof paper or oil-coated paper, in particular palm oil-coated paper,
and paraffin-
3
Date Re cue/Date Received 2023-10-13
coated paper. Alternatively, one can also use conventional or untreated paper
as well as
recycling paper for the wrapping paper.
For the material strip, in particular the sleeve, one preferably uses paper,
in particular
recycling paper, or plastic, particularly preferably paper. Suitable grammages
for the
wrapping paper are in the range of 20 to 100 g/m2. The thickness of the
wrapping film is
expediently in the range of 5 to 100 pm. In expedient embodiments, the
material strip has a
grammage in the range of 20 to 150 g/m2. For the wrapping film, one preferably
uses
polyolefin films, wherein polyethylene films are particularly preferred. Here,
so-called
coextruded films can also be used.
lo The material strip or the sleeve is preferably arranged centered between
the first and the
second side edge. The width of the material strip is expediently less than the
shortest
distance between the first and the second side edge, in particular less than
half as wide and
particularly preferably at most one third as wide as this shortest distance.
The folding or crease line of the wrapping paper or of the wrapping film
preferably runs
substantially parallel, in particular parallel, to the first edge or
substantially parallel, in
particular parallel, to the second edge. Particularly expediently, the folding
or crease line of
the wrapping paper or of the wrapping film preferably runs substantially
parallel, in particular
parallel, to the first edge and substantially parallel, in particular
parallel, to the second edge.
In the two embodiments mentioned above, the folding or crease line of the
wrapping paper
or of the wrapping film preferably runs perpendicular to the first or second
side edge as well
as in particular perpendicular to the first and second side edge. The basic
shape of the
wrapping paper and of the wrapping film preferably constitutes a square or a
rectangle for
many applications, wherein the rectangular basic shape is preferred for many
packaged
goods, in particular foodstuffs. In order to ensure a particularly reliable
and complete
packaging, it has proven particularly advantageous that the folding or crease
line extends
from the first side edge up to the opposite second side edge.
Furthermore, a particularly reliable packaging can also be ensured in that the
folding or
crease line has a distance from the first edge which is in the range of 1/8 to
4/9, in particular
to 2/5, of the extension between the first and second edge (16). For many
applications, it has
proven expedient for the embodiments mentioned above if the distance from the
folding or
crease line up to the first edge of the wrapping paper or of the wrapping film
is in the range
of 8t0 16 cm, in particular in the range of 10 to 12 cm. The width of the
wrapping paper and
of the wrapping film, i.e. the shortest distance between the first and second
side edge, can
4
Date Re cue/Date Received 2023-10-13
be varied within wide ranges and adapted to the size of the packaged goods, in
particular of
the foodstuff, so that a complete packaging is still always successful. Of
course, the length
of the wrapping paper or of the wrapping film can also be varied within wide
ranges, in
particular taking into account the size of the respective packaged goods.
The material strip, in particular the sleeve, is preferably attached to the
outer side of the
wrapping film and in particular of the wrapping paper. For many applications,
it has proven
expedient to glue the material strip, in particular the sleeve, to the outer
side of the wrapping
film or of the wrapping paper. This can surprisingly also be integrated into a
fully automated
mass production process.
With the present invention, the material strip, in particular the sleeve, is
preferably printed, in
particular on the side facing away from the outer side of the wrapping paper
or of the
wrapping film. In this way, the graphic design or the printing of the wrapping
film or of the
wrapping paper can be omitted. Rather, it is sufficient to print only the side
of the material
strip, in particular of the sleeve, facing away from the outer side of the
wrapping paper or of
the wrapping film, or to otherwise configure or provide it with a color and/or
with a pattern.
For many applications, it has proven expedient that the material strip, in
particular the sleeve,
is arranged substantially centered, in particular centered, between the first
and second side
edge. In this way, a visually particularly appealing packaging of a foodstuff
regularly is
achieved. In this way, a particularly stabilized packaging is also achieved.
In addition, the
fingers of the user are particularly reliably protected against liquid
possibly leaking through
the wrapping paper during the handling of the packaged foodstuff.
A visually particularly appealing and also particularly user-friendly wrapping
material can also
be obtained in that the material strip, in particular the sleeve, extends from
the first edge up
to the second edge of the wrapping paper.
The wrapping material according to the invention can be used for manual and
also for
automated packaging of a packaged good, such as a foodstuff. As a result of
the folding or
folding, the packaged good can be aligned on precisely this, which is
accompanied by a
particularly high repeatability of the packaging. This generally has a
particularly positive effect
on the visual appearance and the stability of the packaging. Furthermore, the
time which is
regularly required for packaging the packaged good can be shortened by means
of the folding
or crease already present in the wrapping material according to the invention.

The object of the invention is furthermore achieved by a stack comprising a
plurality of
wrapping materials according to the invention. In one embodiment, the wrapping
materials
combined in this stack are present completely spread out over one another,
wherein the fold
or crease has already been attached beforehand. Alternatively, it can be
provided that the
wrapping materials according to the invention are already present in the stack
folded over
one another along the fold or crease. Hereby, in one embodiment, it can be
provided that the
wrapping materials present folded along the fold or crease are arranged
equally aligned over
one another. Alternatively, it can be provided that the wrapping materials
present folded
along the fold or crease are present alternately stacked over one another in
each case rotated
lo by 1800. This rotation by 1800 can take place alternately both sheet by
sheet of the wrapping
material and also alternately in layers to two or more sheets.
Further features and advantages of the invention result from the following
description, in
which exemplary embodiments of the invention are explained by way of example
with
reference to schematic drawings, without thereby limiting the invention.
Hereby,
Figure 1 shows a first embodiment of a wrapping material according to the
invention in a
plan view on the outer side,
Figure 2 shows a second embodiment of a wrapping material according to the
invention
in a plan view on the outer side,
Figure 3 shows the second embodiment of the wrapping material according to the
invention in a plan view on the inner side,
Figure 4 shows a schematic perspective view of the second embodiment of the
wrapping
material according to the invention,
Figure 5 shows a schematic side view of a first embodiment of a stack of
wrapping
materials according to the invention, and
Figure 6 shows a schematic side view of a second embodiment of a stack of
wrapping
materials according to the invention.
Figure 1 shows a first embodiment of a wrapping material 1 according to the
invention. This
wrapping material can be used, for example, for the packaging of ready-to-eat
processed
foodstuffs such as fast-food foodstuffs. The wrapping material 1 according to
the invention
according to the embodiment depicted in Figure 1 comprises a wrapping paper 2,
the outer
6
Date Re cue/Date Received 2023-10-13
side 12 of which faces the observer. This wrapping paper 2 has a first edge 14
and an
opposite second edge 16 as well as mutually opposite first and second side
edges 18 and
20. These extend in the depicted embodiment from the first to the second edge
14 or 16. The
first edge 14 and the second edge 16 constitute the narrow sides in the
depicted embodiment
of the wrapping material 1 according to the invention. The wrapping material 1
according to
the invention furthermore includes a material strip 22 present on the outer
side of the
wrapping paper 2 in the form of a sleeve in any case completely printed on the
outer side.
This sleeve has a first end 24 and an opposite second end 26 as well as a
first side edge 34
and an opposite side edge 36. The material strip or the sleeve 22 accordingly
extends with
lo .. its first end 24 from the first edge 14 of the wrapping paper 2 up to
the second edge 16. The
second edge 16 of the wrapping paper 2 is in this case expediently congruent
with the second
end 26 of the material strip 22. The wrapping paper furthermore has a crease
line 28
extending from the first side edge 18 up to the second side edge 20. This
crease line 28
divides the wrapping paper 2 into a smaller first section 40 and a larger
second section 42.
In the embodiment depicted in Figure 1, this crease line has been applied to
the inner side
10 lying opposite the outer side 12. In Figure 1, one looks at the outer side
12 of the wrapping
material 1. Accordingly, the material strip or the sleeve 22 is glued to the
outer side 12 of the
wrapping paper 2 in the depicted embodiment. It has proven expedient to attach
the material
strip or the sleeve 22 centered between the first and the second side edge 18,
20. The width
of the material strip 22 is regularly less than the shortest distance between
the first and the
second side edge 18, 20, in particular significantly less than this shortest
distance.
Figure 2 shows a second embodiment of a wrapping material 1 according to the
invention,
likewise in a plan view on the outer side 12 thereof. In contrast to the
wrapping material of
Figure 1, the sleeve 22 is not printed in the section 32, which is located at
the first end 24
thereof, while the remaining outer-side part of the sleeve is printed. The
crease line 28 is
again applied to the inner side. Figure 3 shows a plan view on the inner side
of the wrapping
material 1 according to Figure 2. In this embodiment, the packaged goods are
regularly
placed on this inner side adjacent to the crease line 28 on the larger second
section 42 in
order to wrap it with the wrapping material 1 and to package it. In the
embodiment according
to Figure 3, the adhesive strip 38 is likewise depicted, with which the sleeve
22 is attached
to the outer side 12 of the wrapping paper 2.
Figure 4 shows the wrapping material 1 according to Figures 2 and 3 in an
embodiment in
which it is present in pre-folded form due to the crease line 28 applied to
the inner side or
into which it can be easily transferred due to this crease line. The packaged
goods will be
7
Date Re cue/Date Received 2023-10-13
placed on the inner side due to the different size of the first and second
sections 40, 42 on
the larger section 42, namely for the purpose of bringing about an effective
wrapping adjacent
to the crease line 28. In this mode of operation, the shorter section 40
containing the
unprinted section 32 in the sleeve 22 will be wrapped by the longer or larger
section 42 and
.. thus remains hidden. An immaculate design is thus always obtained.
Figure 5 shows a schematic side view of a first embodiment of a stack of
wrapping materials
according to the invention, as it can be present for example in a carton for
transport or for
removal at the place of use. The individual wrapping materials are already
present in the
stack pre-folded along the crease line 28. Hereby, the outer side of the
longer section 42 lies
lo on the outer side of the shorter section 40. The wrapping materials are
arranged in this case
such that all shorter sections 40 are congruent. Of course, it is likewise
possible to insert the
stack depicted in Figure 5 rotated by 180 into a carton, so that the shorter
section 40 always
comes to lie below the longer section 42 of the same wrapping material sheet.
Figure 6 shows a further embodiment of a stack of wrapping materials according
to the
invention in schematic side view. In contrast to the stack according to Figure
5, the individual
wrapping materials are arranged alternately with respect to the orientation of
the shorter
section 40 folded. Both when using the stack according to Figure 5 and when
using the stack
according to Figure 6, a support surface for the packaged goods is immediately
presented
during removal by a user by means of gripping the shorter first section 40
over the larger
second section 42. This significantly facilitates the flawless packaging
process.
The features of the invention disclosed in the above description, in the
claims and in the
drawings can be essential both individually and in any desired combination for
the realization
of the invention in its various embodiments.
