Bahsedilen bu koruma fonksiyonu ürünün tipine göre seçilen ambalaj malzemeleri ve/veya yapilanmalari ile çözülmektedir. Mevcut teknikte çikolata, sekerleme vb. gida ürünlerinin ambalajlanmasinda kullanilan çesitli malzemeler ve yöntemler bilinmektedir. Çikolata, kakao taneciklerinin mayalanmasi ile elde edilmektedir. Çikolata yaglari, eksimeye açik olmamasina ragmen koku ve tat transferine açiktir. Dolayisiyla çikolatanin disaridan herhangi bir koku ya da tat almasini engelleyici özellikte bir ambalaj yapilanmasinin kullanilmasi gerekmektedir. Piyasada pek yaygin olmasa da kati çikolata, bar ve çikolata kapli sekerleme ambalajinda glasin kagitlar kullanilmaktadir. Baska malzemeler eklenerek üretilmis tablet çikolata ve çikolata ürünlerinin ambalajinda ise folyo/ vaks/ kagit /vaks veya folyo/ termolak gibi pek çok birden fazla katmandan olusan ambalaj yapilanmalari kullanilmaktadir. Mevcut ambalaj uygulanmalarinda tercih edilen bir diger çikolata ambalaji ise alüminyum folyonun direkt olarak kullanildigi yapilanmalardir.Tablet çikolatalarin ambalajlanmasinda ürünü sararak isik, nem ve isi radyasyonuna karsi etkili bir koruma saglayan alüminyum folyo/ termolak yapisindaki ambalaj yapilanmalari üreticiler tarafindan siklikla tercih edilmektedir. Alüminyum folyonun bir yüzüne isil yapisabilir termolak uygulanmasi yapilarak kendi kendine yapisabilir bir ambalaj üretilmektedir. Böylece, makine üzerinde tablet çikolata ambalajlamasi yapilirken, içerisine tablet çikolatayi alan alüminyum folyo, sicaklik uygulandiginda kendi kendine yapismakta ve çikolatayi çevrelemektedir.

TR TR DESCRIPTION Packaging structure with increased shelf life Technical Field The invention is used in the food industry for hazelnuts, pistachios, almonds, etc. It relates to a packaging structure containing aluminum foil to be used in the packaging of all chocolate products with or without additional materials. In particular, the invention is based on a packaging structure containing a polyethylene layer with a flexible and ductile structure in order to prevent the aluminum foil from being torn and/or punctured by the sharp edges of the additional materials, and a binding layer positioned between the aluminum foil and the polyethylene layer to increase the adhesion of the polyethylene layer to the aluminum foil. The packaging structures used to present the products to the consumer are of great importance, and in today's conditions, manufacturers prefer packaging structures that have two basic functions. These basic functions that packaging is expected to have are to protect the product against physical negativities such as impact, wetting, damage, and also to prevent spoilage, spoilage, decay, etc. It also includes chemical protection functions such as preventing the quality from deteriorating due to various reasons. This protection function is solved by packaging materials and/or structures selected according to the type of product. In the current technique, chocolate, candies, etc. Various materials and methods used in packaging food products are known. Chocolate is obtained by fermenting cocoa beans. Although chocolate oils are not prone to rancidity, they are prone to odor and taste transfer. Therefore, it is necessary to use a packaging structure that prevents the chocolate from absorbing any odor or taste from the outside. Although it is not very common in the market, glassine papers are used in the packaging of solid chocolate, bars and chocolate-covered confectionery. In the packaging of tablet chocolate and chocolate products produced by adding other materials, packaging structures consisting of multiple layers such as foil/wax/paper/wax or foil/thermolac are used. Another preferred chocolate packaging in current packaging applications is the structures in which aluminum foil is used directly. In the packaging of tablet chocolates, packaging structures in the aluminum foil/thermolac structure, which wrap the product and provide effective protection against light, moisture and heat radiation, are frequently preferred by manufacturers. A self-adhesive packaging is produced by applying heat-sealable thermolacquer to one side of the aluminum foil. Thus, while tablet chocolate is being packaged on the machine, the aluminum foil that contains the tablet chocolate sticks to itself when heat is applied and surrounds the chocolate. However, especially in the production of tablet chocolate varieties, additional materials such as small and sharp-edged hazelnuts and pistachios may cause tearing problems in the aluminum foil/thermolac structure packaging. These tearing problems can also be caused by bacteria, insect infestation, etc. due to the open areas in the packaging. It can also cause problems such as loss of taste and freshness and spoilage of products. On the other hand, in packaging applications, high adhesion temperatures need to be applied in the thermocoated structure, and therefore, heat at points close to the welding areas can melt the tablet chocolate and distort its form. In the known state of the technique, some applications regarding the subject have been found. In one of these, the patent application numbered EP1462243A1, a combining foil used in the packaging of chocolate spheres is described. This bonding foil consists of a 20 micron thick carrier foil made of polypropylene and a printed aluminum layer applied on top of it. On top of this, a covering foil was applied via covering paint. Application EP1918094B1 discloses an aluminum foil-containing packaging film for packaging chocolate shapes. The invention consists of a composite film in the form of an aluminum foil containing a plastic film made of polypropylene, polyester or polyethylene terephthalate (PET). The thickness of the aluminum foil is approximately 10 micrometers and the thickness of the plastic film is 5 micrometers. The plastic films used in the packaging structures mentioned in the applications in question are made of polypropylene, polyester or polyethylene terephthalate. The packages mentioned do not have the desired level of tear and/or puncture resistance, especially for chocolates containing additional materials with pointed, sharp edges. As a result, due to the negativities and deficiencies mentioned above, the need to make an innovation in the relevant technical field has emerged. Purpose of the Invention The present invention is related to a packaging structure with increased shelf life that meets the above-mentioned requirements, eliminates all disadvantages and brings some additional advantages. The main purpose of the invention is to use hazelnuts, pistachios, almonds, etc. The aim is to present a packaging structure that eliminates the problem of tearing and/or puncturing of the aluminum foil used in the packaging of chocolates containing additional materials by the sharp edges of the said additional materials. The aim of the invention is to provide a packaging structure with tear and/or puncture resistance. The aim of the invention is to provide a packaging structure that eliminates problems such as bacteria, insect infestation, loss of taste and freshness, and product deterioration by eliminating the tearing problem. In this way, the shelf life of the product is also extended. The purpose of the invention is to enable chocolates to be packaged at a lower sealing temperature compared to current practices. By applying a low adhesion temperature, undesirable situations such as chocolate melting or deforming the chocolate that may occur during packaging application are also reduced. One purpose of the invention is to reduce production costs while increasing production efficiency by using low jaw temperatures in the packaging of chocolate. In order to fulfill the purposes described above, the invention uses hazelnuts, pistachios, almonds, etc. It is a packaging structure containing aluminum foil, which is used in the packaging of all chocolate products with or without additional materials, and its feature is; It contains a polyethylene layer with a flexible and ductile structure to prevent the aluminum foil from being torn and/or punctured by the sharp ends of the additional materials mentioned, and a binding layer positioned between the aluminum foil and the polyethylene layer to increase the adhesion of that polyethylene layer to the aluminum foil. In order to realize the purposes of the invention, the aluminum foil thickness is 8-14 microns, the binder layer thickness is 1-4 microns and the polyethylene layer thickness is 6-12 microns. The structural and characteristic features and all the advantages of the invention will be more clearly understood thanks to the detailed explanation given below and therefore the evaluation This should be done taking into account the detailed explanation.

It contains a binding layer (12) positioned between the polyethylene layer (13). By increasing the adhesion of the polyethylene layer (13) to the aluminum foil (11), the layers are prevented from separating from each other at the same rate. Thus, the problem of creep and elongation of the polyethylene layer (13) during tearing and opening of the package is prevented. In the preferred embodiment of the invention, the packaging structure (10) is made of aluminum foil (11), 1-4 microns, with a thickness of 8-14 microns, preferably 12 microns. It preferably contains a 2 micron thick binding layer (12) and a 6-12 micron, preferably 8 micron thick polyethylene layer (13). In the preferred embodiment of the invention, the binding layer (12) contains individuals or combinations selected from the group consisting of ethylene, methacrylic acid, ethylene acrylic acid and polyethylene. In the production of the packaging structure (10) subject to the invention, a polyethylene layer (13) is formed on the aluminum foil (11) by coating polyethylene in granular form with the extrusion process on the aluminum foil (11). Polyethylene has a flexible and ductile structure as a film due to its structure, and thanks to these properties, it provides puncture and/or tear resistance to the packaging structure (10). Thus, hazelnuts, pistachios, almonds, etc. found in chocolate. The sharp ends of the additional materials and the sharp corners of the tablet chocolates are prevented from puncturing or tearing the packaging structure (10). Another feature of polyethylene is its heat sealability at low temperatures. The application of the packaging structure (10) subject to the invention to chocolate products on the packaging machine is carried out with a lower jaw temperature compared to existing packaging applications. As a result, deterioration of the chocolate form is prevented and production efficiency is increased. The production of the packaging structure (10) that is the subject of the invention is as follows: In order to form a polyethylene layer (13) on one surface of the aluminum foil (11), the polyethylene layer (13) to be formed with the aluminum foil (11) while polyethylene coating in granular form is made by the extrusion process. A binding layer (12) is applied between them. Following the application of the binder layer (12) to the surface of the aluminum foil (11), polyethylene material is applied. In the next stage, optional printing can be applied to the other surface of the aluminum foil (11). In the final stage, the packaging structure (10) subject to the invention is made ready for use by applying the slitting process. In the production of the packaging structure (10), optionally, the processing steps can be carried out as printing process, extrusion process and lastly slitting process. Thanks to the structural advantages of the polyethylene layer (13) of the packaging structure (10) subject to the invention, the tear and/or puncture resistance of the packaging structure (10) has been increased and the heat bonding temperature has been reduced. In this way, the packaged product is prevented from deforming during packaging application, and its shelf life is extended by preventing loss of taste and freshness. The packaging structure (10) can be used in the packaging of tablet chocolate, egg chocolate and figured chocolate products. TR TR
