DESCRIPTION:
BRIEF SUMMARY
The present invention is concerned with a packaging film product for the packaging of paper rolls or other products into consumer packages containing one or, preferably, several product units and provided with a handle. The packaging film product concerned is meant expressly for mechanized production of consumer packages, wherein the product units are packaged automatically into consumer packages that contain a certain number of product units and that are provided with a handle. In the first place, the film is suitable for automatic packaging of small paper rolls, such as towel paper rolls or toilet paper rolls, into consumer packages. It may, however, also be applied to the production of group packages for other products.
It is in particular various paper roll products that are packaged into consumer packages that, as a rule, contain 2, 4, 6, 8 or 12 rolls by wrapping the rolls as a relatively tight bundle into a plastic film wrapping. In this way, the package becomes tidy, and it is relatively easy to handle in the store. However, it is a problem of the said prior-art packages that they occupy an unduly large space in the shopping bag of the consumer, relative their weight, even though they in themselves, being ready packages, could also be carried separately if the package had some sort of a handle member for this purpose.
A solution has been sought for the said problem in the Finnish Patent Application No. 840900 by means of the package production method described therein, in which a handle portion is provided for the ultimate package as a part of the production of the package. The use of the said method, however, causes its arrangements of additional devices in the packaging equipment even though in this way quite a usable package is achieved.
In the present invention, a solution has been sought for the said handle problem of the package out of a different starting point, as compared with the method described in the said Patent Application No. 840900. In the present invention, the starting point has been the packaging film itself, wherein attempts have been made to make the film such that, in spite of processability by means of conventional packaging equipment, the film provides a package with a handle without additional equipment or operations proper, in the packaging process itself. This objective has been reached by means of a packaging film product or preparation, whose essential characteristics come out from the accompanying claim 1.
The invention will be described by means of the attached drawing, wherein
FIG. 1 illustrates the packaging film product in accordance with the invention,
FIG. 2 illustrates a finished product package packaged into the film product concerned and
FIG. 3 illustrates another embodiment of the packaging film product in accordance with the invention.
The packaging film product in accordance with the invention has been produced, e.g., as a plastic film web 1 or as some other suitable film web so that the edge borders 1a and 1b of the web 1 have been folded as substantially equal widths towards each other onto the middle area of the web so that the edge borders cover at least a substantial proportion of the middle area of the web. At one edge of the folded, two-fold web, a longitudinal handle strip 2 has been formed by joining the film layers, placed one above the other, together. Into the said handle strip, grasping openings 3 or opening blanks have been prepared with a spacing corresponding to the spacing of the package units.
The handle strip 2 may be prepared, e.g., by means of hot sealing 4. In stead of heat sealing, it is, of course, also possible to use other modes of joining, such as glueing. The grasping openings 3 may be prepared, e.g., by means of an appropriately heated tool so that the film layers adhere to each other at the edge portions of the opening, whereby a firm and tidy grasping opening is provided. Alternatively, the openings 3 may be just perforated tear-off openings. An adequate grip is also provided by means of a longitudinal linear cut or linear tea
