Definitions
- the present invention relates to a biaxially oriented polypropylene film with perforation and a package of biaxially oriented polypropylene film with a perforation as an opening aid.
- biaxially oriented plastic films particularly thermoplastic polymer films, and especially biaxially oriented polypropylene films
- the polyolefin film protects the packaged goods against rapid drying or loss of flavor with very low material usage.
- Uniaxially oriented films show a low tear strength in the direction of orientation and can be easily controlled in this direction and tear further.
- uniaxially oriented films are not usable in many fields, among other things due to insufficient transverse mechanical strengths.
- the biaxial orientation on the one hand, produces the desirable high strengths (moduli) in both dimensions; on the other hand, but also the preferred directions are equalized. This has the consequence that for opening a foil packaging (eg biscuit bag) first a high force must be overcome in order to tear the foil.
- a crack will be planted even when using very low tensile forces uncontrollably continued.
- WO 98/2312 describes packages which are pre-cut by a laser beam. These packages have a multilayer structure. In particular, a metallic intermediate layer is provided which is intended to prevent the laser beam from cutting through the film. This packaging is lavish and expensive due to the lamination with a metal layer. About the exact configuration of the packaging is disclosed in the description nothing.
- the object underlying the invention is achieved by a biaxially oriented film of polypropylene with perforation lines, wherein the film has at least two perforation lines, which are parallel to each other and are located at a maximum distance of 10mm and wherein the perforations of the two lines are staggered with respect to each other and wherein there are gaps between the perforations of undamaged foil and the distances between the perforations are longer than the perforations.
- the object is further achieved by a method for wrapping piece goods, in which a perforated film unwound from a roll and used for packaging the piece goods.
- 1 shows an embodiment of the film (2) with circular perforations (1) with a length (diameter) B.
- the length of the distances between the perforations corresponds to the length A.
- Both parallel perforation lines are arranged at a distance from each other C. In the embodiment according to FIG. 1, the distances A are longer than the length of the perforations B.
- the perforation line are offset relative to one another such that the center of the respective perforation is aligned with the center of the opposite distance.
- FIG. 3 shows perforations with a rectangular geometry, whereby here too B ⁇ A.
- Fig. 4 shows a film with diamond-shaped perforations, as they are produced for example by rotating blades.
- Fig. 5 shows a film with elliptical perforations. Again, B ⁇ A.
- Fig. 6 shows a possible geometry of a needle perforation which results in propeller-like perforations.
- Fig. 7 shows a film web having a plurality of perforation double lines in the longitudinal direction.
- Fig. 8 shows a package (3), which is opened by breaking along the perforation double line (4).
- the two parallel, offset perforation lines form a predetermined breaking point in the film, in which a crack propagates very controlled after tearing.
- the tear continues to run after tearing along one of the perforation line or between the two parallel perforation lines controlled.
- the foil packaging is opened only as far as desired.
- the packaging according to the invention is particularly suitable for ordered or stacked piece goods, e.g. Cigarette packets, as well as pasty products such as
- the perforation lines can be applied to the film web in a suitable pattern.
- the lines are straight.
- the perforation lines can be produced by mechanical perforation, for example by means of needles or knives or by a laser beam or in another way, so that a continuous hole is formed in the film.
- perforations are also understood as meaning thin areas in which no continuous hole is produced in the film, but the film only becomes thinner at the corresponding points due to removal of material, for example by a laser beam which only penetrates to a predetermined depth.
- 10 to 80% of the original film thickness preferably 20 to 60% of the original film thickness in the region of the thin location remain. In this way, a closed package is obtained, which continues to meet all hygienic requirements and their barrier properties are not impaired.
- incisions or thin areas alternate undamaged film sections whose length A is determined by the distance of the perforations.
- distances are thus the areas of undamaged film which extend from the end of a perforation to the beginning of the subsequent perforation in the same perforation line.
- the geometric shape of the perforation can vary and depends on the perforation method. Needles or rotating blades can be used for the perforation. For perforation lines from non-continuous thin sites, laser or ultrasound are preferred. Needle perforations create circular or ellipsoidal or propeller-like shapes that result from the needle and foil being in contact at the perforation and moving relative to each other.
- Knife perforations produce more rectangular ones or diamond-shaped cuts or thin spots. Laser and ultrasound methods allow different geometric shapes. Except for circular perforations, all perforations have a greater extent in one of the two fundamental directions (longitudinal direction), which is aligned along the perforation line.
- the perforations have in the longitudinal direction in general a length B of 0.1-6 mm, preferably 0.3 to 4 mm, in particular 0.5 to 2 mm.
- the extent of the perforation transversely to this longitudinal direction is correspondingly smaller and is generally 5 to 80%, preferably 10 to 50% of its extension in the longitudinal direction.
- Circular and approximately circular perforations have a diameter of 0.1 to 5 mm, preferably 0.3 to 3 mm.
- For a particularly low tearing force in particular perforations with a length of> 1 to 6 mm are preferred, in particular also lengths of 1.5 to 6 mm or 2 to 4 mm are suitable.
- the mechanical strength of the film is not impaired.
- These embodiments can be excellent to wind up a film roll and unwind easily on the packing machine again.
- the length A of the sections ie the undamaged film between the perforations, is> 0.1 to 10 mm, preferably 1 to 6 mm and depends on the length of the perforations. For embodiments with long perforations of, for example, 1.5 to 6 mm, distances of> 4 to 10 mm are preferred.
- the dimensions of the distances A are selected in relation to the perforation so that the length of the distances is greater than the length of the perforations.
- the length A of the distances is at least 10% greater than the length B or the diameter B of the perforations.
- the length B of the perforations is 5 to 60% of the length A of Distances, preferably 10 to 50%.
- perforations and distances apply in the same way also to perforations in the form of non-continuous thin spots, which in turn may likewise be circular, elliptical or oblong.
- the dimensions of the distances between the perforations are generally constant, or vary only slightly within the usual manufacturing accuracy.
- the length of each perforation along a line does not vary, or only slightly (up to 10%).
- the diameter of the holes or the length of a perforation is constant.
- the perforations and distances of the two parallel perforation lines of a predetermined breaking point have approximately the same dimensions.
- the second essential feature of the predetermined breaking point according to the invention is the arrangement of the perforations of the two parallel perforation lines to one another. It has been found that staggering the perforations of the two lines surprisingly improves the control of crack propagation. In this staggered arrangement, a perforation of the second line does not start at the same height as the opposite perforation of the first line. As a result, the perforation of the second line partially covers the opposite distance of the first perforation line. In a preferred embodiment, the center of the sections of the first perforation line is aligned with the center of each opposite perforations of the second perforation line, so that a symmetrical perforation pattern is formed.
- the arrangement of two parallel, mutually offset perforation lines significantly improves the control of the crack profile.
- the invention also enables the packaging to be broken off at the
- Packaging is arranged so that its edge extends at the level of the double line.
- the perforation lines are generally applied in the machine direction of the film.
- the perforation can be combined simultaneously with the cutting of the film to narrower film widths and thus carried out in one operation. Alternatively, the perforation can also be done before or after cutting to the finished film width.
- the film for perforation for example, over rollers with suitable perforation tools out, for example, these rollers are equipped with needles or knife blades. In the case of lasers or ultrasonic perforations, corresponding tools are positioned below or above the film web.
- the film to be perforated is unwound from a roll, the perforations according to the invention are applied and the perforated film is then rewound and the roll used at the facilities for packaging of piece goods, ie unwound and used for wrapping the goods.
- the perforations do not or only insignificantly impair the wrapping behavior of the film, so that the perforated film can be wound up and unwound with the usual devices.
- the perforation according to the invention does not impair the mechanical stability of the film in such a way that, when winding and unwinding the film breaks, film tears, thickening or stretching occur.
- the roll of perforated film is used to make the package of the invention.
- the packaging according to the invention is particularly suitable for ordered or stacked piece goods, as well as pasty products such as butter, sausage and the like. It is possible for the consumer to tear the film along a predetermined predetermined breaking point in such a way that individual pieces can be removed without other uncontrolled fall out in the case of general cargo.
