Abstract

Food-safe, antimicrobial multilayered packaging consists of at least two layers with specific functions, wherein the inner layer (1) necessarily has an antimicrobial function and is preferably made of a polymer material to which a zinc-based compound is added, together with an outer layer (2) that provides a structural support and to which an aesthetic finish can be applied, as well as a plurality of other, intermediate layers with specific functions.

Description

Multilayer PACKAGING is non-toxic antimicrobial FOOD

technology sector of the invention

The present invention pertains, in general, the technological sector of food packaging and refers, more specifically, to a non-toxic antimicrobial and multilayer packaging, able to pack food and ensure their physical, chemical and microbiological.

The proposed packaging is composed of layers made of special materials and active principles which make it active and capable of removing microorganisms such as bacteria and fungi that promote premature deterioration of the food.

The invention provides all the traditional protective conditions of a common package, however, due to its antimicrobial characteristic, eliminates microorganisms such as bacteria and fungi inside. This differential makes the object of the invention packaging able to prolong the integrity of the products on the shelf and increase the safety of consumption without compromising product quality.

known prior art

The state of the art in this technological sector comprises packaging with antimicrobial principles, but these conventional packages consist only of a single layer, or monolayer containers are. Regarding the manufacturing process employed is the linear monolayer extrusion technique for manufacturing such packages. To impart the antimicrobial property such packages are manufactured with biocidal additives based on silver and / or triclosan-based, or commercial compounds. Cites, for example, commercial line Irgaguard® additives (BASF / CIBA SPECIALTY CHEMICALS) and the base compounds of nanosilver and silver (Nanox).

A problem related to these monolayer packaging refers to the fact that only need to be considerably thick layer, it also assumes the function of structural packing. From this fact derive significant impacts on a piece of increasing costs, since the additives are too expensive and high thickness implies the use of greater amounts of additives. Many application possibilities are eliminated due to the high cost of packaging.

In addition, by having only one layer, these conventional packages are subject to significant interactions with the external environment, which causes degradation phenomena of its active ingredient. The active principles used are ionic or molecular species which can easily undergo oxidation in the presence of oxygen (or other free radicals). These reactions are accelerated by increasing the temperature and exposure to light. Thus, these casings have time potentially short antimicrobial action.

It is noteworthy that these conventional monolayer packages are limited in the type of exterior finish that can receive, as is the reaction of varnishes and paints applied to the principles antimicrobial active, which leads to neutralization of principle.

Additionally, the use of the biocidal additives based on silver and / or triclosan basis is problematic, since such products has been questioned regarding its toxicity. These compounds can be harmful to human health in certain intake levels in view of the absence of human and animal organisms. Silver can cause neurological problems, kidney, indigestion and headaches. Regarding the triclosan is known the possibility of promoting the formation of cancer. Both are already intense questioning by investigators of community health and being rejected by packaging manufacturers.

Novelty and objects of the invention

The present invention relates to a multilayer container produced with antimicrobial antimicrobial zinc based additive. Zinc is an element present in the metabolic systems of humans and animals, so that in many situations nutrition and medicine is added in view of the critical need of humans and animals by this chemical. Thus, it is not considered toxic and gives the pack a great advantage of being non-toxic and differential. This feature greatly facilitate its acceptance by the market and easy release by regulatory agencies such as ANVISA, Animal Health and other organs.

The proposed packaging is produced with the concept of functional multilayer. The active layer (antimicrobial) is the inside of the container in contact with the packaging of the food. Hence, this layer is protected from the external environment and its isolated active principle and absent from reactions with oxygen or other free radicals present in the atmosphere. This design ensures greater durability of antimicrobial principle and greater antimicrobial action time for packing. Gives the food more security and for a longer time, and increase the shelf life of stored products.

The multilayer configuration ensures the outside layers of packaging without the active ingredient, but with structural features and finishing. Not being antimicrobial outer layer packaging art may admit any visual finish. Thus it is possible to make printing images with traditional paints and varnishes without reacting with the active ingredient.

As the active inner layer has no structural function, it becomes feasible to produce containers with small thicknesses. As a result, small thicknesses require smaller amounts of polymers and especially smaller amounts of active ingredients. Since the active ingredients account for most of the cost of the package, this differential certainly ensures the economic viability of antimicrobial multilayer packaging on traditional monolayer packaging.

Detailed Description of the Invention

The present invention relates to an antimicrobial and non-toxic multilayer packaging for foodstuffs comprising at least two layers which specific functions, wherein the inner layer (1) is necessarily endowed with antimicrobial function, consisting preferably of a polymer material additivated with any zinc-based compound, which performs the antimicrobial function, associated with an outer layer (2).

The inner layer (1) is not restricted to an additive or polymer, but any antimicrobial additive, preferably zinc base by lack of toxicity and any compatible polymer. Suitable polymers for forming the inner layer include, but are not limited to, LDPE, LLDPE, HDPE, EVOH, PET, nylon, PVC, PP, BOPP or another polymer non-toxic and compatible with the antimicrobial additive.

The packaging may consist of multiple layers wherein each layer have specific functions. Thus, other layers may be manufactured with any polymer or any other material of interest, or may be LDPE, LLDPE, HDPE, EVOH, PET, nylon, PVC, PP, BOPP or another polymer, or aluminum films or adhesives, or other materials. It depends on the functions that exercise and physical and chemical properties that will be required of them according to the characteristics and properties required for the products to be packaged. At first there is no restriction on the number of layers that make up the package. The packaging may be made from two layers until the required amount requested by the project.

The multilayer casing will be produced with layers perform important functions in the system as multilayer packaging. Each layer has its own function and contributes to the fundamental performance of the multilayer packaging in antimicrobial protection function. The intermediate layer preferably perform the function of blocking / barrier undesirable compounds to the food or the active ingredient. Thus contribute to the efficiency and durability of the antimicrobial function. The outer layers are structural and receiving art packaging function. The structural layers are dimensioned to prevent fracture during use of packages to be generated, which would expose the internal active layer to the external environment (which would decrease the efficiency and durability of active ingredient). Still ensure good weldability in its application, enabling the generation of vacuum and at the same time sealing the packaging means (increases efficiency and durability of the antimicrobial function). Referring now to the accompanying drawings, we see illustrated two-layer film in Figure 1 is provided with an outer layer (2), which has function of receiving the aesthetic finish (art) of the pack, provide structural support to the package and act as protective barrier of the antimicrobial additive. Since the inner layer (1) is a heat sealable layer with antimicrobial additive that has direct contact with the food, or food packaging means is surrounded by the inner layer (1).

In Figure 2 we see another embodiment of the invention, wherein the package comprises three layers: an inner layer (1) with antimicrobial additive, which involves the packaging of the food; an outer layer (2) which receives the aesthetic finish of the container and provides structural support and; an intermediate layer (3) having barrier properties against humidity, gases and antimicrobial additive.

Finally, Figure 3 shows an exemplary embodiment of a package of seven layers consisting of an inner layer with antimicrobial additive (1) and an outer layer of finishing functions (2), limiting a number of intermediate layers: a structural layer (4), a gas barrier layer (5), another structural layer (6), a moisture-proof barrier layer (7) and a barrier layer with antimicrobial additive (8).

We see, therefore, that there are numerous packaging design options, depending on the desired properties. The above cases are merely exemplary of possible embodiments of the proposed concept, not having any intention of limiting the scope of protection thereto only, however, the present report aims to realize any embodiment which falls within the inventive concept presented.

It was in this specification of an invention endowed with industrial applicability, novelty and inventive activity, being coated with all the requirements laid down by law industrial property for receiving the claimed privilege.
