Definitions

  • the invention relates to a package for a product, in particular food, with a lower film on plastic, which forms the bottom of the package and serves to hold the contents, and with a plastic top film which forms the top of the package and covers the contents.
  • Such packaging both for the food and food as well as for the non-food sector, are found in everyday life diverse, for example, in packaging for sausage, meat or cheese pieces.
  • relatively hard, lower shells thermoformed underfoils are in use, then on a relatively soft, printed top film is sealed.
  • the product is here fresh sealed in the lower shell.
  • Other forms of packaging such as shrink bags or skin packaging are also known.
  • the upper film has a greater modulus of elasticity than the lower film.
  • the advantages of the invention are, in particular, to be seen in the fact that a new type of packaging is created in which the upper film, in simple terms, is stiffer than the lower film. Due to the larger modulus of elasticity, a higher rigidity is achieved for the upper film than for the lower film with its lower modulus of elasticity. This results in new use variants for packaging, for example, in the presentation of the packaged goods.
  • a material saving can be realized because when using a rigid top film, the entire stiffness and strength of the packaging is effected by the top film, and thereby the already flexible bottom film can be made thinner.
  • the elastic modulus on the one hand is not strict physical relationship between the elastic modulus on the one hand and the rigidity or hardness on the other hand;
  • the modulus of elasticity also called Young's modulus of elasticity
  • the invention can also be described with the flexural modulus.
  • the flexural modulus of the top film of the packaging according to the invention is (clearly) higher than the flexural modulus of the bottom film. So you can call the top film as hard or rigid, not very flexible (not very flexible). In contrast, the terms soft, flexible, bendable can also be used for the lower film.
  • the modulus of elasticity E is defined in the context of the present invention as the slope of the graph in the stress-strain diagram at uniaxial loading within the linear elasticity range. This linear region is also referred to as Hooke's straight line.
  • the modulus of elasticity of the top film is greater than 1000 N / mm 2 , preferably greater than 1500 N / mm 2 and particularly preferably greater than 2000 N / mm 2 .
  • the modulus of elasticity of the lower film is less than 1500 N / mm 2 (but always smaller than that of the upper film), preferably less than 1000 N / mm 2 and particularly preferably less than 800 N / mm 2 .
  • the modulus of elasticity of the top film is advantageously more than 2500 N / mm 2 and / or the modulus of elasticity of the bottom film is advantageously less than 500 N / mm 2 .
  • the (tensile) modulus of elasticity of a film or composite film can be determined from the standard DIN EN ISO 527-1-3, the flexural modulus according to the standard DIN EN ISO 178.
  • the data in the context of the present invention relate to the measurement conditions according to the above. Standards. If comparisons are made in terms of modulus of elasticity or bending modulus in the context of the present invention, these relate to the same conditions in each case, including the dimensions of the upper and lower film used.
  • the upper film is formed substantially flat and the lower film thermoformed.
  • the contents can be introduced.
  • thermoforming formerly called thermoforming, thermoforming or vacuum forming - is a widely used method for forming thermoplastics, in which often semi-finished sheet on large rolls are fed to the thermoforming machines and obtained by Glaschristumformen a one-sided open hollow body with a wall thickness reduction becomes.
  • the relatively stiff upper film is preferably printed in a preferred embodiment. This results in the great advantage that the printed image on the top film has a much more uniform appearance compared to a printing of the softer top films known from the prior art, as it hardly or not at all waves. Thus, according to the invention, greater packaging quality can be realized.
  • a barrier lacquer can additionally be applied directly to this printed image.
  • a barrier lacquer with SiO x silicon oxide.
  • the application of further coatings, such as heat-protective lacquer, is also preferred.
  • Said printed image is applied according to a further advantageous embodiment on a carrier layer and is covered by at least one further layer, against which the printed carrier film can be laminated on the printed side.
  • This composite then forms the top film.
  • a relatively thin support layer having a thickness of e.g. about 10 to 100 .mu.m, such as OPP, OPA, CPA, CPP, OPS or OPET are counter-printed and then laminated against the further layer, which on the side facing away from the carrier layer can again be laminated with a sealing / barrier film.
  • the printed image is applied directly to the surface of the top film facing away from the product, for example in straight printing.
  • Other alternatives for applying the printed image are possible, these are known in the art.
  • the various printing methods such as gravure printing, flexographic printing, offset printing, screen printing, pad printing, digital printing, HD printing, ink jet printing, etc. are known in the art.
  • a lacquer can be applied to the printed image, for example a barrier lacquer or a heat protection lacquer.
  • an imprint between two film layers is present, for example between a carrier layer and a cover layer, while a heat-protective lacquer may be provided on the outside of the outer film layer.
  • the upper film has no printing, but only a lacquer layer in at least one inner layer or on at least one of its outer layers.
  • the paints can be based on known polymers, such as, for example, polyurethane PU), polyvinylbutral (PVB), acrylate, nitrocellulose (NC) or also NC / PU etc.
  • the usable lacquers for example, here are heat sealing lacquers, anti-slip, protective lacquers, heat-protective lacquers, peel lacquers, antifogging lacquers, antistatic lacquers, water-repellent lacquers, spritmü lacquers, release lacquers, overprint varnishes, overwritable lacquers, gloss lacquers, matt lacquers, UV protective lacquers, light-protective lacquers, conductive Called paints and barrier coatings. Before painting, it is also possible to use a primer so that the paint adheres better to the top film or between two layers of the top film.
  • the above advantage of applying a print image to (or in) the top film arises, for example, even if, according to a preferred embodiment, the surface of the top film is more than 50%, preferably more than 75% substantially flat.
  • the remaining areas are, for example, bent over at the edges or - which will not be the rule - made thinner; Rather, the top film will usually have a uniform thickness.
  • Said printing is preferably arranged at least on the substantially planar sections. However, this does not mean that the entire plane area must be printed. It is also possible that the printing can go into non-planar areas, or that in such areas an independent printing is provided.
