    Cardboard packaging for active packaging of fresh fruits and vegetables, and its manufacturing process. This invention is related, in general, to the field of packaging technology for plant products, such as whole fresh fruits and vegetables that usually have some surface microbial load. Specifically, this invention relates to a new carton package characterized by having an antimicrobial active coating, based on a polymeric compound in combination with essential oils that form inclusion complexes with cyclodextrins. The vapors of the essential oils are released from the cardboard as relative humidity is reached sufficiently high in the vicinity of this coating that is next to the packaged product, and these vapors have an antimicrobial action against fungi, yeasts and bacteria, both altering the quality of the product as pathogens for consumers. This new packaging significantly increases the food safety and shelf life of the foods that are packaged in it. (Machine-translation by Google Translate, not legally binding)

    antimicrobial comprising a polymeric compound and cyclodextrin inclusion complexes with essential oils or components of these oils or mixtures of both as an aqueous solution, emulsion, or dispersion at a rate of 5 to 20 g / m2, preferably at a rate of 8 to 17 g / m2
    5 b) drying of the antimicrobial coating applied in a).
    In a particular and preferred embodiment of the invention, the applied antimicrobial coating has the following composition: Polymeric compound, in a weight concentration of 5 to 30%, preferably 10 to 10 to 25%;
    - inclusion complexes of cyclodextrins with essential oils or components of these oils or mixtures of both, in a weight concentration of 5 to 30%, preferably 10 to 25%;
    -water, in a concentration by weight of 40 to 90%, preferably 50 to 80%.
    The drying of the antimicrobial coating of step b) of the process can be carried out in different ways, although it is preferably carried out by drying at a temperature between 70 ° C and 180 ° C, preferably between 100 ° C and 170 ° C.
    As for the type of cardboard plate to be used for the manufacture of the container of the invention, it should preferably be of a type of cardboard selected from the following: pressed cardboard or paperboard, of one or several layers of paper; or single-wave corrugated cardboard or double-sided cardboard (consisting of two smooth faces and a corrugated sheet), or
    25 two-wave cardboard or double-double cardboard (formed by 3 smooth and 2 corrugated faces), or triple cardboard (formed by 4 smooth faces and 3 corrugated faces). The said wave or channel of the corrugated sheet will be of the microchannel type (wave with a height of less than 2 mm); or of small wave type (wave with a height between 2.5 and 3.5 mm); or of medium wave type (wave with a height between 3.6 and 4.5 mm); or big wave (wave
    30 with a height between 4.6 and 5.5 mm).
    The manufacture of the package object of this invention will preferably be adapted to a package form such as the box indicated in Figure 2, which is stackable.
    35 In its manufacture, the container may carry a socket (12) for the placement of the fruits or vegetable units to be packaged. This socket (12) may be of material

    Figure 3. Another practical example of embodiment of this invention. The cardboard box (5) has the antimicrobial active coating described above (as described in Figure 2 above) applied throughout its internal surface, and also has a socket (12) for the placement of fruit or vegetable units They are going to be packed. These cells serve to avoid hitting each other the units of packaged product, and improve their presentation. This socket may be of plastic or paper or pressed cardboard material, and may or may not include in the same construction material some type of antimicrobial or adsorbent agent of ethylene, applied as a coating or according to another procedure on that material.
    Figure 4. Another practical example of embodiment of this invention. The cardboard box (5) has a sheet (13) of paper or plastic material that is used to wrap completely but not hermetically (below and above) the fruit and vegetable units packaged in this box (5). This envelope (13), which is placed inside the box (5), may be of plastic or paper material, and may or may not include, in the same construction material, some type of antimicrobial agent or ethylene adsorbent, applied as a coating or according to another procedure on that material. This envelope can be not complete, and cover only the upper part of the box (5), and can be formed by a single sheet or by two sheets (13) that can be opened as indicated in this Figure 4. In this In the latter case, this partial wrap (13), which does not cover the inside of the bottom of the box (5), may be attached to the sides (14) of the box (5).
    Figure 5. Another practical example of embodiment of this invention. The cardboard box (5) has a sheet (13) of paper or plastic material that is used to completely or partially wrap the units of packaged product, as explained in Figure 4 above. And the package (5) object of this invention also has a socket (12) with the functionality and features that have been explained in Figure 3 above. In this Figure 5 the packaging elements (12) and (13) are seen separated so that their shape and arrangement can be better appreciated.
    Figure 6 shows these same packaging elements (12) and (13) placed in place inside the box (5).
    Figure 7. Plaque test of the antimicrobial action of the active carton object of this invention. The active antimicrobial cardboard shown in Figure 7 is obtained by applying a coating based on a mixture of essential oils in
