Definitions
- thermoformable films with anti-fog properties are provided.
- the invention relates to a transparent, thermoformable film which is suitable for packaging goods containing moisture, in particular food.
- the film according to the invention may be single-layered or multi-layered.
- MAP packs modified atmosphere packaging
- a known packaging of this type consists of two packaging elements between which the packaged goods are arranged.
- the first packaging element is usually to a trough, ie formed into a cup-like recessed embossing, which receives the packaged.
- Such troughs are usually formed by deep drawing suitable films.
- the trough is covered by the second packaging element in the operation of a lid, whereby a closed space is formed in which the packaged goods is.
- Both packaging elements are connected to each other via a peripheral sealing edge (welding edge), wherein the intermediate space is preferably filled with Schutzgas ⁇ atmosphere before the sealing process.
- the material which forms the first packaging element (trough) must have a certain mechanical strength and dimensional stability in the temperature range customary for the respective application, so that the packaging provides sufficient protection during transport and storage for the packaged goods.
- the material forming the second packaging element (lid) is usually transparent so that the packaging material underneath is clearly visible.
- packaging was developed in which not only the lid, but also the bowl is transparent.
- Comparatively thin films are known in the prior art which are suitable inter alia for packaging food and which are designed such that they suppress the formation of droplets and mist on their surface.
- these films may be coated with an additive having anti-fog properties or contain an additive having anti-fog properties.
- reference may be made, for example, to US Pat. No. 5,766,772.
- the films of the prior art in which the dripping and misting is suppressed, are not deep drawing. If one were to form troughs by means of such films by deep-drawing, these troughs would not be suitable for receiving packaging goods, since the mechanical properties of the films are not sufficient to ensure sufficient rigidity and bending strength of the packaging. Therefore, the known in the art films are possibly suitable as a lid.
- the packaging material must be easy to process, ie it must be reliably processed with the aid of conventional thermoforming apparatus in a short time, on the other hand it must form a sufficient rigidity already a short time after the deep drawing process, after leaving the thermoforming apparatus, the predetermined shape of the trough not to lose.
- at least the surface of the packaging material facing the trough interior should be heat-sealable so that the packaging can be hermetically sealed by sealing (welding) the lid with the trough later after the packaging material has been introduced.
- the used Packaging materials meet the toxicity standards that are placed on food packaging.
- thermoformable packaging materials suitable for the formation of troughs packaging materials in comparison to the materials suitable for cover often have a much higher layer thickness, the requirements on the optical properties are much higher because the light has to cover a much greater distance through the packaging material of the trough, as is the case with the lid. While the layer thickness of the cover forming materials is often in the range of 5 to 50 microns, thermoformable packaging materials often have layer thicknesses of 200 microns and more because of the required mechanical properties. In order to meet the high demands that are generally placed on food packaging, the deep-drawable packaging material suitable for the formation of troughs must have a high degree of transparency, without the mechanical properties deteriorating.
- thermoformable packaging material may be impaired.
- the invention is therefore based on the object to provide an improvedmaschines ⁇ material available, which allows the control of the packaged goods.
- the packaging material should be transparent, deep-drawable and thus be suitable for forming troughs of packaging for food, wherein mechanical strength and optical transparency should meet high standards.
- the formation of mist and droplets should be suppressed to the extent that the view of the packaged goods is not impaired by the material forming the cavity. This suppression of fog and dripping should also be maintained if the thermoformable packaging material is thermally treated as a result of its processing or for other reasons such as sterilization of the packaging.
