    Mineral composition and its use as an additive for the manufacture of cardboard furniture packaging and / or packaging.
    OBJECT OF THE INVENTION
    The present invention is indicated as an additive for the manufacture of packaging and / or containers that allows it to function as a thermal insulator, anti-humidity (stabilizing action), flame retardant (limited fire contribution) and antimicrobial. Thus the packaging, packaging (of paper, cardboard and polymeric materials) and cardboard furniture made of our mineral composition derived from igneous stones, with properties that keep the products in an optimal state of humidity, temperature, flame retardant and inhibiting microbial growth, preserving the qualities of the products, minimizing the environmental impact in addition to its easy recycling.
    The mineral composition is added in the mixing process in the manufacture of cellulose pulp or polymeric materials with a specific percentage (between 1% to 15% by weight), it is the most economical and ecological solution in the market .
    The present invention is intended for the sectors of packaging, packaging (cardboard or plastics) and cardboard furniture.
    BACKGROUND OF THE INVENTION
    It is well known that the containers and packaging used today generate a great controversy at the level of environmental impact, due to the overexploitation of non-biodegradable or renewable resources. An increasing number of consumers require that packaging and packaging be recyclable and safer. Recyclable packaging is one of the public's priorities when buying products, as it is seen as a protective factor for the environment.
    Consumers and legislators are increasingly aware of packaging. This trend is particularly noticeable in Europe. In the Netherlands, for example, a tax is applied to packaging manufacturers according to the average CO2 emissions of the materials they use - from 36 to 57 cents per kilogram of packaging of

    aluminum, 6 cents per carton
    Cardboard is a material that is manufactured from several layers of superimposed paper. The cardboard is recycled in the blue container and in this way it can be used again. But it can also be used to create furniture. Nowadays, consumers buy all kinds of cardboard furniture for its originality and its cheaper cost.
    There are four forms of water contamination in a closed container or package:
    1) water vapor in the air inside the package;
    2) water vapor absorbed by the materials inside the package;
    3) water vapor on the walls of the package; Y
    4) the water vapor that enters through the package.
    Currently, there is a wide variety of desiccant or absorbent products on the market, such as: montmorillonite clay, silica gel, molecular sieve or synthetic zeolite, calcium oxide (CaO), calcium sulfate (CaS04) etc. Among these products, the most suitable for each application should be chosen. However, due to the conservation measures of the products (temperature and relative humidity -HR) and to avoid water vapor in the form of condensation, it is necessary to keep them at an optimum level of humidity and there are no products that cover all the parameters suitable to avoid such moisture.
    The most useful measure that combines temperature and RH is the dew point. The dew point is the temperature at which the water vapor content in the air exceeds saturation and the excess water is squeezed out forming water condensation. An example of air condensation at 0 ° C cannot maintain more than 4.84 g / m3 of water vapor; at 40 ° C the air cannot maintain more than 50.7 g / m3 of water vapor. An effective desiccant will absorb water vapor in the air, lowering the RH to the point that water cannot condense.
    Because many products destined to the food sector need to be kept at an optimum temperature, they are usually refrigerated in industrial refrigerators. This can cause considerable deterioration of stored products, due to the increase in humidity and / or the appearance of harmful fungi (from 40% RH), such as Penicillium digitatum, Rhizopus stolonifer, Aspergillus spp. Also, many pastry products Y

    Industrial bakeries are usually sold in kraft paper bags to preserve freshness and facilitate the transport of these products by the consumer, but the loss of moisture from fresh products reduces their properties.
    Silica gel desiccant bags, which are used for moisture absorption, are known in the market, but in addition to having high manufacturing costs, they are also known for their toxicity by the dust that creates several of their compounds, the cobalt chloride, silica oxide, which can generate silicosis when breathed {which causes cough, fever and difficulty breathing and usually evolves into pulmonary fibrosis) and have an environmental impact, in addition to the high costs for industrial use.
    EXPLANATION OF THE INVENTION
    Heat and humidity are two fundamental factors for microbial growth. Currently, existing products on the market such as packaging, cellulose packaging and / or trays of polymeric materials intended to contain everyday products (eg cookie boxes, electronic packaging, medicines, fruit trays and meats etc.) none have the qualities described in the present invention.
    The present invention is characterized by the properties of the additive, a mineral composition in the packaging, cellulose pulp containers, cardboard furniture manufacturing and polymeric materials, which make four very important properties, the thermal property, flame retardant property, the moisture protection property (stabilizer), the antimicrobial property and easy to recycle, respecting the environment and with a low manufacturing cost, in addition to extending the life of the product. Preferably, from homogenous igneous rocks
    The main minerals of our composition are preferably from igneous rocks, sedimentary and metamorphic rocks (magnesium, iron, aluminum, calcium oxide, silicon dioxide), which are mixed in the manufacture of cellulose pulp and / or polymeric materials between percentage of 1% to 15% by weight and with a particle diameter between 50 nm and 1000 pm.
    The use of the mineral composition represents a great economic advantage for these types of packaging, containers and furniture, since by homogeneously integrating the mineral composition with cellulose pulp or polymeric materials, they make the interaction between the cellulose network or polymeric materials and the mineral composition is uniform and regulates moisture

    by the properties of the minerals in our formulation (MgFeCaOAI) 6Si02 rich in Mg {between 1 and 25%), Fe (between 1 and 23%), CaO (between 1 and 25%), Al ( between 0.1 and 11%) and S¡02 (between 16 and 75%), which has a coefficient of thermal conductivity of about 0.20 W / (K m), resulting in the improvement of the humidity regulation (as absorbent, due to its nanoporous structure) inside the packaging due to chemical interactions between the mineral composition and the product's RH.
    Among the polymeric materials, thermoplastics are linear polymers, which may or may not be branched, since they are not crosslinked, they are soluble polymers in some organic solvents, they are capable of being molten and are therefore recyclable. If we compare them with other types of plastics, thermoplastics are manufactured and used in very large quantities and among them the most frequent are polyethylene (PE), polypropylene (PP), polystyrene (PS), expanded polystyrene (PSE), polyvinyl chloride (PVC) etc. In fact, more than half of the total number of plastics processed corresponds to the five plastics cited.
    Our mineral composition has the fire retardant property, which applied on packaging, containers and cardboard furniture delay the consequences of product ignition, because the nature of the ingredients of our invention is derived from igneous rocks, whose chemical elements can withstand very high temperatures .
    In food, one of the main problems are contamination by the emission of mycotoxins, derived from fungi (microbes). Among the most harmful are Penicillium digitatum, Rhizopus stolonifer, Aspergillus spp, Fusarium spp etc., which grow in high relative humidity (between 50% to 90% RH). The use of our invention counteracts the effects of moisture and heat, thereby reducing the chances of microbial growth in containers or packages primarily intended for human use.
    The absorption capacity of the product with an RH between 20% and 90% ranges between 10% and 45% on its weight in water. At an ambient temperature of 22 ° C and a RH of 40%, the absorption capacity is 20 ± 3%.
    In addition, the mineral composition has the ability to regulate humidity, when the product is stored in a humid environment, the mineral composition absorbs moisture up to 50% of its weight in water. If the storage conditions of the packaged products /

    packaged changes to a lower humidity, the mineral composition slowly releases the amount of water retained in its structure, making the content of the stored product maintain optimal humidity conditions This process is due to the permeability of the porosity of the mineral compound between K <10-6 - 10 ^ m.s1.
    PREFERRED EMBODIMENT OF THE INVENTION
    The present invention relates to a composition preferably formed by mineral compositions, preferably extracted and selected from igneous rocks, (with the following mineral composition (MgFeCa0AI) 6Si02) used for the production of packaging, containers (of paper, cardboard and materials polymeric), as well as cardboard furniture, with properties that keep the products in an optimal state of humidity, temperature, fireproof protection and inhibiting microbial growth, with a percentage of our mineral compound mixed in the manufacturing process of the products between 1% to 15% by weight and with a particle diameter between 50 nm and 1000 pm.
    Example 1:
    As an example of said invention, mention is made of a cardboard container of approximately 200 g with 2% by weight (4 gr / U of our mineral composition) (10% Mg, 6% Fe, 10% CaO, Al at 2% and S00 at 72%) with a particle diameter of 400 pm of our mineral composition. This percentage is added in the manufacturing process at the wet end (in the phase - mixing tub) together with the other additives (glues, bleaching agents, fillers, fibers, etc.) following the standard industrial conditions for their manufacture. With these minerals, the products contained in said container preserve an optimum state of humidity, fire protection, inhibition of microbes and thermal insulation.
    Example 2:
    Another example of packaging manufacturing is kraft paper in the form of paper bags, which are used to sell the bread after being baked. 5 bags of kraft paper of 5 gr each were manufactured and our mineral composition (8% Mg, 8% Fe, 15% CaO, 2% Al and 67% Si02) was added with a percentage of 3% by weight (150 mg / U of our mineral composition) and with a particle diameter of 200 pm. This percentage is added in the manufacturing process at the wet end (in the phase - mixing tub) together with the other additives (glues, bleaching agents, fillers, fibers etc.) following the conditions

    Industrial standard for manufacturing.
    A study was carried out with 10 freshly baked breads (standard industrial conditions) with a 45% RH and crispy state of the bread (it was considered very crispy to the touch, giving it a subjective assessment of 5/5), 5 loaves were introduced in bags of Kraft paper made with our mineral composition (study group) containing 3% by weight. Likewise, 5 loaves were introduced in kraft paper bags without our mineral composition (control group) to make comparisons of humidity and freshness between 12 hr and 24 hr.
    At 12 h it was observed in the study group that the product (bread) had a RH of 43%, averages with a trotee® moisture measuring device and were still crispy (4/5), compared to the control group, 41% RH and crispy (3/5) were measured. At 24 hr it was observed that the breads of the studied group had a RH of 39% and a crunchy state (2/5), compared with the control group, observing a RH of 34% and a state that could no longer be considered “ Crispy "(0/5).
    It was observed that the kraft bags with our mineral composition held the humidity more, compared to the control group and kept the crunchy product (bread) longer, with the bread being in the soft control group.
    Example 3:
    Another example of manufacturing is the use of thermoplastics that are used in trays for food products, in medicines, electrical appliances etc. As an example of thermoplastic manufacturing - polyethylene (PE), intended as a 10-gram tray for packaged meat, is added our mineral composition (15% Mg, 8% Fe, 15% CaO, Al 2 % and YES2 at 60%) with a percentage of 5% by weight (500 mg of our mineral composition) and with a particle diameter of 300 pm.
    An experiment was carried out with polyethylene (PE) trays to check the thermal property and moisture stabilization inside the tray. 5 trays were made with the mineral compound and 5 without said compound.
    They were packed in the 10 trays with 1 apple in each tray and all the trays were closed with transparent plastic film with an ambient temperature of 28 ° C and an 80% RH. At 6 hours two trays were checked with the mineral composition and

    two without the mineral composition having an environmental RH of 84% and a temperature of 26 ° C. Humidity and temperature were measured with a meter (Trotee T210), and it was found that in both trays that had the mineral compound the internal RH was 60%, while in the two trays without the mineral compound the internal RH was of 79%.
    At 24 h, the following six trays were analyzed (three with the mineral compound and three without the mineral compound) with an ambient temperature of 30 ° C and an 82% RH. It was observed that the trays with the mineral compound had a RH between 57% and 59%, the other trays without the mineral compound had a RH between 78% and 80%.
    In this way it was observed that the mineral compound significantly regulates the RH inside the packaging. One form of industrial application is by adding the mineral compound in the stirring process with mixing the catalyst (benzoic peroxide).
    Example 4:
    10 biscuit cellulose tablets of 1 cm thick each were made, 5 tablets with the mineral compound (10% Mg, 6% Fe, 10% CaO, 2% Al and 2% SIO2 ) at 5% by weight and a thickness size of the mineral compound of 400 pm, with a weight approx. of 27 gr and 5 tablets without the mineral compound weighing approximately 25 gr, to check the consequences of ignition of the product.
    A constant flame of fire was applied for 2 min at 1600 ° C and it was observed that the 5 tablets with the mineral compound did not burn, but only gave off smoke. The time of fire exposure to a constant flame of 5 min was increased and the result was the same, it only smoked.
    A constant flame of fire was applied for 1.5 min at 1600 ° C with the other tablets without the mineral composition. It was observed that, during this time of exposure to fire, the tablets began to burn until they consumed all the cellulose.
    In this way, it was observed that the mineral compound has a better behavior against fire, that is, that the material is combustible, but not flammable.
