Description

„Verpackung für Tiefkühl- oder Kühlprodukte, insbesondere Speiseeis" "Packaging for frozen or refrigerated products, in particular ice cream"
B e s c h r e i b u n gDescription
Die Erfindung betrifft eine Verpackung, insbesondere flexible Verpackung für Tiefkühloder Kühlprodukte, wie Speiseeis od. dgl., insbesondere Spitztüte zur Aufnahme von Speiseeis, mit einer Mono- oder Mehrschichtenfolie oder Laminat, die bzw. das eine bedruckte Substratschicht, insbesondere PE-, PP-, Aluminium- und/oder Papierbahn, oder aluminisierte PE-, PB-, PETP- oder Papierbahn umfasst.The invention relates to a package, in particular flexible packaging for frozen or cooled products, such as ice cream. The like., In particular topping bag for receiving ice cream, with a mono- or multilayer film or laminate, the or a printed substrate layer, in particular PE, PP , Aluminum and / or paper web, or aluminized PE, PB, PETP or paper web.
Derartige Verpackungen sind allgemein bekannt, wobei die dafür verwendeten Folien meist noch sogenannte Barriereschichten umfassen.Such packages are generally known, the films used for this usually still include so-called barrier layers.
Die bekannten Verpackungen fassen sich jedoch meist sehr unangenehm an. BeimHowever, the known packaging is usually very uncomfortable. At the
Herausnehmen der Verpackung aus einem Kühl- oder Tiefkühlfach bildet sich an derRemoving the packaging from a refrigerator or freezer is formed at the
Oberfläche sehr schnell ein feuchter Niederschlag, der die Verpackung „glitschig" macht.Surface very quickly a damp precipitate, which makes the packaging "slippery".
Darüber hinaus ist dieser feuchte Niederschlag auch haptisch unangenehm.In addition, this wet precipitate is also haptically unpleasant.
Des weiteren ist das Aussehen der Verpackung durch den erwähnten Niederschlag und aufgrund von Tropfenbildung nicht besonders schön.Furthermore, the appearance of the package is not particularly beautiful due to the mentioned precipitate and due to the formation of drops.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Verpackung der eingangs genannten Art zu schaffen, die gegenüber dem Stand der Technik sowohl in optischer als auch haptischer Hinsicht erheblich verbessert ist. Insbesondere soll die Verpackung optisch den Eindruck eines gekühlten oder tiefgekühlten Produkts vermitteln, wobei beim Anfassen der Verpackung die entsprechende Temperatur nicht unmittelbar gefühlt wird.The present invention is therefore an object of the invention to provide a package of the type mentioned, which is significantly improved over the prior art, both in optical and haptic terms. In particular, the packaging should give the impression visually of a chilled or frozen product, wherein when touching the packaging, the corresponding temperature is not immediately felt.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is solved by the characterizing features of claim 1.
Die bedruckte Außen- bzw. Sichtseite der Folie, aus der die Verpackung hergestellt ist, soll erfindungsgemäß mit einer nicht-gewebten bzw. non-woven-Schicht aus gesponnenem PB (Polypropylen)- und/oder PE(Polyethylen)- od. dgl. Material, wie auch PETP, versehen sein, deren Dicke und Verteilung derart sind, dass das Druckbild im wesentli- chen unverändert scharf erkennbar bleibt. Die non-woven-Schicht vermittelt den Eindruck, als hätten sich auf der Oberfläche der Verpackung Eiskristalle gebildet. Dementsprechend wird optisch der Eindruck eines gekühlten oder tiefgekühlten Produkts vermittelt. Wenn man dann jedoch die Verpackung anfasst, fühlt sich die Verpackung überraschenderweise relativ warm und trocken an, und zwar bedingt durch die Oberflächen- struktur der non-woven-Schicht, die natürlich auch einen Isoliereffekt hat; denn zwischen den Fingern eines Benutzers und der bedruckten Seite der Verpackungsfolie entstehen durch die non-woven-Schicht innerhalb derselben Luftpolster, die einen entsprechenden Isoliereffekt haben. Die non-woven-Schicht kann auch aus organischen Fasern bestehen.The printed outer or visible side of the film from which the packaging is produced, according to the invention with a non-woven or non-woven layer of spun PB (polypropylene) - and / or PE (polyethylene) - od. Like. Material, as well as PETP be provided whose thickness and distribution are such that the printed image remains essentially unchanged sharply recognizable. The non-woven layer gives the impression that ice crystals have formed on the surface of the packaging. Accordingly, the visual impression of a chilled or frozen product is conveyed. However, when one then touches the package, the package surprisingly feels relatively warm and dry, due to the surface structure of the non-woven layer, which of course also has an insulating effect; because between the fingers of a user and the printed side of the packaging film caused by the non-woven layer within the same air cushion, which have a corresponding Isoliereffekt. The non-woven layer may also consist of organic fibers.
Vorzugsweise weist die non-woven-Schicht folgende Eigenschaften auf: Flächengewicht: 10 - 40 g/m2 Preferably, the non-woven layer has the following properties: basis weight: 10 - 40 g / m 2
Dicke: 130 - 200 micronThickness: 130 - 200 micron
Luftdurchlässigkeit bei einem Luftdruck von etwa 190-200 Pa, insbesondere etwa 196 Pa: 4000 - 9000 L/m2/s.Air permeability at an air pressure of about 190-200 Pa, in particular about 196 Pa: 4000 - 9000 L / m 2 / s.
Mit den vorgenannten Eigenschaften wird die Qualität des Druckbilds an der Sichtseite der Verpackungsfolie nur unwesentlich beeinträchtigt. Selbst eine Schrift mit einer Schrifthöhe von etwa 1 ,0 mm laßt sich durch die non-woven-Schicht noch konturen- scharf erkennen und entsprechend gut lesen.With the aforementioned properties, the quality of the printed image on the visible side of the packaging film is only slightly affected. Even a font with a font height of about 1.0 mm can still be recognized by the non-woven layer and can read accordingly well.
Die non-woven-Schicht kann farblos, weiß, aber auch in jeder anderen beliebigen, vorzugsweise hellen Farbe gehalten sein. Sofern das Druckbild auf einer aluminisierten Oberfläche angebracht ist und die non-woven-Schicht weiß eingefärbt ist, ergibt sich besonders deutlich der optische Effekt einer eiskristallinen Oberfläche. Weitere vorteilhafte Eigenschaften der non-woven-Schicht sind: Längs-Bruchlast: 800 - 980 N/nThe non-woven layer can be colorless, white, but also in any other, preferably light color. If the printed image is applied to an aluminized surface and the nonwoven layer is colored white, the optical effect of an ice-crystalline surface is particularly evident. Further advantageous properties of the non-woven layer are: Longitudinal breaking load: 800-980 N / n
Quer-Bruchlast: 350 - 650 N/n.Transverse breaking load: 350 - 650 N / n.
Auch hat sich als vorteilhaft erwiesen, wenn die non-woven-Schicht eine Längsdehnung von 6 bis 10%, insbesondere etwa 7 bis 9%, und eine Querdehnung von 8 bis 20%, insbesondere 9 bis 17% besitzt, wobei die Längs-Weiterreißfestigkeit 600 — 850 cN, und die Quer-Weiterreißfestigkeit etwa 800 - 1300 cN beträgt.Also has proved to be advantageous if the non-woven layer has a longitudinal strain of 6 to 10%, in particular about 7 to 9%, and a transverse strain of 8 to 20%, in particular 9 to 17%, wherein the longitudinal tear strength 600-850 cN, and the transverse tear strength is about 800-1300 cN.
Die Basisfolie kann aus PE (Polyethylen), PP (Polypropylen), PETP-Aluminium und/oder Papier bestehen. Vorzugsweise ist die Basisfolie an ihrer bedruckten Seite aluminisiert,. d.h. eine aluminisierte PE-, PP-, PETP- oder Papierbahn.The base film can be made of PE (polyethylene), PP (polypropylene), PETP aluminum and / or paper. Preferably, the base film is aluminized on its printed side. i.e. an aluminised PE, PP, PETP or paper web.
Die Verpackungsfolie kann als — wie eingangs erwähnt — Mono- oder auch Mehrschich- tenfolie bzw. Laminat ausgebildet sein. Sie kann eine Barriereschicht umfassen, insbesondere aus Aluminium. Vorzugsweise ist die innen liegende bzw. dem Lebensmittel zugekehrte Seite der Verpackungsfolie mit einer flüssigkeits-undurchlässigen Schicht kaschiert, insbesondere einer lebensmittel-verträglichen Kunststoffschicht, wie PE oder PP. Da es sich hier grundsätzlich um eine an sich bekannte Technologie handelt, soll hier darauf nicht näher eingegangen werden.The packaging film may be formed as a mono or else multi-layer film or laminate, as mentioned above. It may comprise a barrier layer, in particular of aluminum. Preferably, the inside or the food facing side of the packaging film is laminated with a liquid-impermeable layer, in particular a food-compatible plastic layer, such as PE or PP. Since this is basically a technology known per se, it will not be discussed in detail here.
