[0001] DESCRIPTION

[0002] TUBE ICE CREAM PACKAGING PRODUCTION METHOD

[0003] Technical Field

[0004] The invention relates to a tube-shaped ice cream packaging production method.

[0005] The invention relates in particular to a production method for tube ice cream packaging made of OPP (Oriented Polypropylene) film and cardboard materials, without the use of oil, and free of polyethylene (PE) material.

[0006] State of the Art

[0007] In tube ice creams, which are one of the widely consumed types of ice cream, frozen ice cream is filled in tube-shaped packagings and offered for sale.

[0008] In the present art, tube ice cream packagings essentially consist of extruded PE (polyethylene) material, cardboard and extruded PE (polyethylene) material, and are produced by coating PE (polyethylene) material on the front and back surfaces of the cardboard through an extrusion method. The total approximate weight of tube packaging in the present art is 210 g / m2.

[0009] The application of PE (polyethylene) material coating in tube ice cream packagings increases the scrap rates in two ways. In addition to the PE (polyethylene) material scrap formed during extruded PE (polyethylene) material coating, it causes PE (polyethylene) material cardboard scrap formed during printing. The printing process is also applied on the surface of the cardboard coated with PE (polyethylene) material. During PE (polyethylene) coating, thickness and weight differences occur in the PE (polyethylene) material applied to the surface. The ink remains on the outer surface and additional lacquer is applied on the ink. Since there is contact with hands and lips during the consumption of ice cream, water-based or solvent-based lacquer applications contain migration risk. On the other hand, due to surface roughness in coating with PE material, flaking may occur and the packaging printing clarity quality can be low. In addition, when using oil-based inks, the process requires the use of costly UV lamps with a low lifetime to dry the ink. The amount of silicone oil used during the curling process cannot be controlled, and the silicone oil remaining on the packaging surface is likely to remove the ink from the packaging. In addition, since the packages are nested together during production, the transfer of ink to the inner surface becomes unavoidable. Furthermore, the silicone oil used in the lip curling process applied on the lip part of the tube packaging can leave a residue in the lip part of the product, and this may cause the product to emit a taste or odor during the consumption of the ice cream. In addition, adhesion problems are observed in lip curling due to excessive transfer of silicone oil during production. However, the moisture content of the paper is crucial in the lip curling process. For this, extra moisture and water are applied to the paper, however this causes the risk of bacteria formation. Since it is not possible to separate the PE coated product from the paper, its recycling is limited. For this reason, in the state of the art, there is a need to eliminate the problems experienced in tube ice cream packagings produced by PE extrusion coating method.

[0010] An example of the state of the art in the research conducted in the literature is document numbered NL1006886C1. Said document relates to a frozen ice cream. In said invention, a frozen ice cream obtained from a cocktail mixture and filled in tube ice cream packaging is described. However, the whole structure of said packaging is not disclosed.

[0011] As a result, the existence of the above problems and the inadequacy of the existing solutions have made a development in the relevant technical field necessary.

[0012] Object of the Invention

[0013] The present invention relates to a tube ice cream packaging production method that eliminates the above-mentioned disadvantages and brings new advantages to the relevant technical field.

[0014] The main object of the invention is to introduce a method for producing tube ice cream packaging made of OPP (Oriented Polypropylene) film material, without the use of oil, and free of PE (polyethylene) material.

[0015] The object of the invention is to introduce a method that eliminates the risk of migration experienced in water-based or solvent-based lacquer applications thanks to the absence of lacquer application and resets the risk of migration by keeping the ink under the OPP (Oriented Polypropylene) film material.

[0016] Another object of the invention is to introduce a method for producing tube ice cream packaging with inner and outer surfaces capable of direct contact with food.

[0017] Another object of the invention is to introduce a method that ensures that the scraps occur only in the OPP film material and that there is no scrap from the cardboard, thanks to applying the printing process only on OPP (Oriented Polypropylene) film material and applying a lamination process after printing.

[0018] Another object of the invention is to introduce a method that eliminates the problem of flaking and provides high clarity printing in printing on OPP film material, thanks to the smoothness of the printing surface.

[0019] Another object of the invention is to introduce a method that does not include usage of oil in the lip curling process and eliminates the risks associated with it.

[0020] Another object of the invention is to introduce a method that eliminates the risk of polyethylene mixing with food by melting or in the form of fibers in extruded PE (polyethylene) coated products thanks to the OPP film material having a film layer.

[0021] Another object of the invention is to introduce a method that makes it possible to recycle tube ice cream packaging, as it is easier to separate the OPP film material from the paper for recycling purposes, even though the recycling possibilities of PE coated tube packaging are limited.

[0022] The structural and characteristic features of the invention and all advantages thereof will be understood more clearly with the figures given below and the detailed written description provided with reference to these figures. Therefore, evaluation must be made by taking these figures and detailed description into account.
