Definitions

  • the invention relates to a laminate, in particular for producing a packaging, as well as a container produced therefrom according to the preambles of claims 1 and 10.
  • Laminates in particular for the production of packaging, have been known for a long time and are often used for the production of bag-like and box-like, and often cuboidal packages for solid, liquid and pasty food and beverage. and consumables of all kinds used.
  • Such made of a laminate packaging are characterized mainly by their low weight, their simple and at the same time cost manufacturability, as well as their unproblematic disposability and by their small compression volume in deflated condition.
  • auxiliary means for opening a package which has been produced from such a conventional laminate
  • attempts have therefore been made in the past to improve the opening behavior of such a package by modifying the laminate.
  • a film layer disposed within the laminate was monoaxially stretched and formed in thickness such that the stability of the laminate was largely determined by the internal monoaxially stretched laminate layer, which represented the thickest layer, or layer, in the laminate. In this way it could be achieved that the laminate could be torn straight, so that a targeted opening of a packaging made of such a laminate was made possible.
  • such a laminate also has numerous disadvantages, which are due to the fact that the monoaxially oriented layer in the known laminate on the one hand present as an inner layer and on the other hand due to its stretching higher Siegeitemperaturen when connecting laminate ends or edges, for example in As part of the manufacture of a package, required as the corresponding non-oriented material, preferably polypropylene.
  • the monoaxially stretched material can only be printed very badly, which in turn makes it impossible to use this film as an outer layer, in particular also because of the requirement that the monoaxially oriented layer must be an inner layer in combination.
  • no transparent packaging could be produced with the aforementioned laminate, since the known laminate is cloudy, that is not transparent.
  • the object is achieved by a laminate, in particular for producing a packaging, having at least two layers, one or, in the case of more than two layers, an outermost layer consisting of a first monoaxially oriented material.
  • the monoaxiai oriented material according to the invention is not arranged as an inner, but as an outermost layer, so that a cracking of the monoaxially oriented material can be initiated directly in the outermost layer of the laminate.
  • the monoaxially oriented material which according to the invention preferably consists of a polyolefin, preferably of polyethylene or more preferably of polypropylene, is present directly in a sealing area, so that in the course of the production of a package two laminates, namely on the basis of the respective monoaxially oriented layers, at relatively low sealing temperatures can be sealed together and the monoaxia! oriented material thus represents itself the sealing medium.
  • the laminate further comprises a further layer of a second monoaxially oriented material which is disposed on the side of the laminate opposite the layer of a first monoaxially oriented material, likewise preferably too extreme.
  • an essential point of the invention is that the first monoaxiai oriented material, soft in a container produced from this laminate, or a packaging, preferably the outside of the container or the packaging is stretched with a draw ratio in the range of 1: 3 to ⁇ : 15, preferably in the range of 1: 3 to 1: 10.
  • the respective film of the monoaxially stretched material advantageously becomes mechanically more stable, so that the stretched material mechanically stresses even in small thicknesses more strongly than previous monoaxially oriented layers, or such comprehensive laminates and in particular, such inventively stretched layers can be fed to an industrial printing process.
  • the respective film thickness of the films made from a first and / or a second monoaxially oriented material very thin, i. in the range of 5 pm to 50 pm, preferably in the range of 12 pm to 40 pm, and more preferably in the range of 15 pm to 30 pm, the second monoaxially oriented material having a draw ratio in the range of 1: 1.5 to 1: 5, preferably in the range of 1: 1.5 to 1: 4 and more preferably in the range of 1: 2 to 1: 3 is stretched.
  • the above-mentioned, very thin film thicknesses according to the invention are, on the one hand, material-saving and, moreover, enable a very diverse use of the stretched thin webs
  • Material which constitutes the outermost layer of the laminate is suitable for imparting to the further layers of the laminate, in particular if they are thicker, in particular substantially thicker than the film layer of the monoaxially oriented material, a tear direction which corresponds to the orientation of the monoaxially oriented material ,
  • Such directed tearing can be further optimized according to the invention further by the provision of a further, namely the second made of a monoaxially oriented material film layer, on the other outermost side of the laminate, so that a directional Tearing open even across the R GmbHrtchtung further not or only weakly stretched film layers is possible.
  • the novel laminate can be printed optimally, in particular in straight printing and / or reverse printing, since it is possible according to the invention to select the stretching of the film of monoaxially oriented material and its layer thickness in such a way that it is optimal for the printing process is suitable and has no inhomogeneities, especially no soft areas, both in terms of tensile strength and in terms of its temperature resistance, so that precise printing of the outermost layer of the novel laminate is possible.
