Definitions

  • the invention relates to a packaging, in particular under vacuum, for products releasing moisture when they are enclosed in the packaging, particularly for food products such as cold meats such as slices of ham, or meat, the packaging comprising an advantageously waterproof envelope made of a transparent material.
  • Packages of this type are widely known, but have the major drawback that the moisture released by the product and thus enclosed in the sealed envelope condenses.
  • the product then bathes inside the envelope in a liquid, which reduces the shelf life of the product and deteriorates its quality.
  • the presence of the liquid gives the product a less attractive appearance and forces the consumer to open the envelope, taking great care to prevent the liquid from causing damage.
  • the humidity on the surface of the product gives it an appearance making it less appetizing in the eyes of the consumer.
  • the present invention aims to provide a packaging of the type stated above, which does not have the drawbacks which have just been exposed.
  • a package according to the invention is characterized in that it comprises, disposed between said envelope and the external surface of the product, on at least part of it, a layer of a material which absorbs the moisture from the product packed and transparent at least after absorption of moisture.
  • the layer of this material consists of a sheet of paper of the tissue paper type, the grammage of which is chosen so that it becomes transparent under the effect of the absorbed moisture.
  • the absorbent material has been bonded beforehand to the material forming the envelope.
  • product 1 for example a certain number of slices of ham, is enclosed, hermetically, in an envelope sealed closed 2.
  • the packaging of the product 1 is made for example under vacuum, in a manner known per se.
  • a sheet 3 is respectively disposed of a material which has a large suitable moisture absorption capacity and is completely transparent, at least after have absorbed the moisture released by the product.
  • tissue has the two properties of absorbing moisture and becoming transparent after absorption. Thus all the parts of the tissue which are in contact with the product become completely transparent. Therefore, when the sheets 3 are placed as shown in Figure 1, the packaging is completely transparent and the sheets of tissue paper 3 are invisible to the consumer.
  • the grammage of the paper should be adapted to the amount of moisture which will be released from the product 1, inside the envelope 2, so that the paper can absorb all of this moisture.
  • the grammage of the paper is to be chosen accordingly and is advantageously between 20 and 25 g / m2 depending on the paper used.
  • the paper becomes too dense and has a somewhat grayish appearance.
  • the paper is not completely transparent after absorbing the moisture.
  • the sheets 3 could also be fixed, for example by gluing to the surface of a ribbon of the transparent material forming the envelope, before the vacuum packaging operation of the product therein. This fixation could be done in any suitable way. Of course when the fixing is done by gluing, it is advisable to use an adhesive material which is compatible with the product and the liquid which it gives off and does not in any way affect the food qualities thereof. Any other way of fixing can however be applied.
  • any material other than tissue paper can be used provided that this material satisfies the two conditions, namely that it absorbs moisture and is transparent, or in its natural state, either after absorption of moisture.
  • this material satisfies the two conditions, namely that it absorbs moisture and is transparent, or in its natural state, either after absorption of moisture.
  • the invention thus provides a packaging which could be entirely transparent, insofar as the absorbent material is completely transparent, that is to say invisible to the eye of the consumer.
