Den foreliggende opfindelse angår et lamineret materiale til fremstilling af væsketætte emballagebeholdere, hvilket materiale omfatter et bærelag, fortrinsvis af opskummet polystyren eller af et fiberma-5 teriale, såsom papir, og på begge sider af dette anbragte plastlag.The present invention relates to a laminated material for the manufacture of liquid-tight packaging containers, which comprises a support layer, preferably of foamed polystyrene or of a fibrous material such as paper, and on both sides of this plastic layer.
Det er kendt at fremstille emballager af lamineret materiale, og sådant materiale anvendes særlig ofte ved fremstilling af éngangsemballager til flydende : 10 fyldegods. Det laminerede materiale omfatter et forholdsvis tykt bærelag og på begge sider af dette anbragte plastlag. Bærelaget, der kan bestå af opskummet polystyren eller et fibermateriale, såsom papir, muliggør formning af en stabil emballage, og det på inder-15 siden liggende plastlag udgør den egentlige væsketætte emballagebeholder. Det udvendigt liggende plastlag tjener til at beskytte emballagen og giver den et tiltalende ydre.It is known to produce packaging of laminated material, and such material is particularly frequently used in the manufacture of disposable liquid packaging: 10 filling goods. The laminated material comprises a relatively thick support layer and on both sides of this disposed plastic layer. The support layer, which may consist of foamed polystyrene or a fibrous material such as paper, allows for the formation of a stable packaging and the inner layer of plastic constitutes the actual liquid-tight packaging container. The outer plastic layer serves to protect the packaging and gives it an attractive appearance.
På grund af det forholdsvis tykke og stive 20 bærelag fører en deformering, som f.eks. opstår ved at emballagen tabes eller på anden måde udsættes for mekanisk påvirkning, ofte til, at emballagen begynder at blive utæt.Due to the relatively thick and rigid support layer, a deformation such as occurs when the packaging is dropped or otherwise subjected to mechanical impact, often causing the packaging to become leaky.
Dette er særlig et problem ved større emballa-25 gebeholdere ikke blot på grund af, at disse som følge af deres vægt udsættes for et stærkere stød, hvis de tabes, men også på grund af, at størrelsen nødvendiggør anvendelsen af et lamineret materiale med særlig kraftigt og stift bærelag, som vil blive knækket i 30 skarpe vinkler, så at også det indvendige lag sønderrives .This is especially a problem with larger packaging containers not only because of their weight, due to their weight, if they are dropped, but also because the size necessitates the use of a laminated material with special strong and rigid support layer, which will be broken at 30 sharp angles, so that the inner layer is also torn.
Den efterhånden mere og mere anvendte type af lamineret materiale, som omfatter et bærelag af skumplast med på begge sider anbragt plastlag, er som føl-35 ge af sin bjælkelignende konstruktion meget stift ogThe increasingly used type of laminated material, which comprises a foam plastic support layer with plastic layers arranged on both sides, is very rigid as a result of its beam-like construction.
DK 152485 BDK 152485 B
2 tåler store påvirkninger uden at knækkes, men når påvirkningerne overstiger den maksimale grænse, sker knækningen meget brat og forårsager skarpe bukkelinier, der så godt som uden undtagelse medfører, at det 5 indvendige plastlag revner.2 can withstand great stresses without breaking, but when the stresses exceed the maximum limit, the cracking occurs very abruptly and causes sharp bending lines which almost without exception cause the 5 inner plastic layer to crack.
De emballagebeholdere, som er tilvirket af lamineret materiale af denne type, er således alle behæftet med den ulempe, at de ved mekanisk påvirkning eller deformering har liden modstandskraft mod utæt-10 hed.Thus, the packaging containers made of laminated material of this type are all at the disadvantage of having little resistance to leakage by mechanical action or deformation.
Den ulempe kan fjernes ved, at bærelaget i det laminerede emballagemateriale gøres mindre stift eller tyndere, men dette medfører den uønskede effekt, at den af materialet fremstillede emballagebeholder bli-15 ver mindre solid og stabil. Dette begrænser også den emballagestørrelse, som kan fremstilles af materialet.The disadvantage can be removed by making the support layer of the laminated packaging material less rigid or thinner, but this causes the undesirable effect that the packaging container made of the material becomes less solid and stable. This also limits the size of packaging that can be made from the material.
Formålet med den foreliggende opfindelse er at afhjælpe de omtalte ulemper og at tilvejebringe et lamineret materiale til fremstilling af en emballagebe-20 holder, som tåler endog kraftige stød og deformeringer uden at blive utæt.The object of the present invention is to overcome the aforementioned disadvantages and to provide a laminated material for the manufacture of a packaging container which can withstand even strong shocks and deformations without being leaked.
Disse formål er ifølge opfindelsen opnået ved, at et lamineret materiale af den indledningsvis beskrevne art er ejendommeligt ved, at adhæsionskraften 25 mellem det af de nævnte plastlag, der skal vende mod emballagebeholderens inderside, og det tilstødende bærelag er betydelig mindre end adhæsionskraften mellem bærelaget og det ydre plastlag og er således afpasset, at det indvendige plastlag ved deformering af 30 en af emballagematerialet fremstillet emballagebeholder løsner sig fra det tilstødende bærelag.These objects are achieved according to the invention in that a laminated material of the type described initially is characterized in that the adhesive force 25 between the said plastic layer which faces the inside of the packaging container and the adjacent support layer is considerably less than the adhesion force between the support layer and the outer plastic layer and is adapted so that, when deforming a packaging container made of the packaging material, the inner plastic layer detaches from the adjacent support layer.
Ved hjælp af det laminerede emballagemateriale ifølge opfindelsen muliggøres der en simpel tilvirkning at emballagebeholdere, som tåler en kraftig de-35 formering uden at blive utætte, eftersom laminatets 3By means of the laminated packaging material according to the invention, it is possible to make a simple operation for packaging containers that can withstand a strong deformation without being leaked, since the laminate 3

indre lag ved deformering af emballagebeholderen løsner sig fra det tilstødende lag og udgør en fra det tilstødende lag helt eller delvis løsnet indre beholder.inner layer upon deformation of the packaging container detaches from the adjacent layer and constitutes an inner container completely or partially detached from the adjacent layer.
I det følgende vil en udførelsesform for embal-5 lagematerialet ifølge opfindelsen blive beskrevet nærmere under henvisning til tegningen, der skematisk og i stor målestok viser en del af et emballagemateriale ifølge opfindelsen set i snit.In the following, an embodiment of the packaging material according to the invention will be described in more detail with reference to the drawing, which schematically and on a large scale shows part of a packaging material according to the invention seen in section.
Materialet er fremstillet helt af plast og om-10 fatter et centralt bærelag 1 af opskummet polystyren og på begge sider af dette anbragte lag 2, 3 af homogen plast, f.eks. polystyren. Tykkelsen af det centrale lag 1 er 0,5-2 mm og de ydre plastlags tykkelse er ca. 0,1 mm.The material is made entirely of plastic and comprises a central support layer 1 of foamed polystyrene and on both sides of this layer 2, 3 of homogeneous plastic, e.g. polystyrene. The thickness of the central layer 1 is 0.5-2 mm and the thickness of the outer plastic layer is approx. 0.1 mm.
15 Emballagematerialet ifølge opfindelsen frem stilles ved, at skumplastlaget 1 ekstruderes på kendt måde, hvorefter de to homogene plastlag 2 og 3 ved ekstruderingsmetoder anbringes mod skumplastlaget 1's sideflader på en sådan måde, at der opnås ønsket ad-20 hæsion imellem lagene. Den ønskede, svagere adhæsion mellem bærelaget 1 og det homogene plastlag 3, som efter fremstillingen af emballagebeholderen skal udgøre dennes indre, tættende lag, tilvejebringes ved, at temperaturen under påføringen af det homogene lag 25 3 reguleres, så at der.opnås en passende adhæsions kraft.The packaging material according to the invention is prepared by extruding the foam plastic layer 1 in known manner, and then applying extrusion methods to the two homogeneous plastic layers 2 and extrusion against the side surfaces of the foam plastic layer 1 in such a way as to obtain the desired adhesion between the layers. The desired weaker adhesion between the support layer 1 and the homogeneous plastic layer 3, which after the manufacture of the packaging container is to form its inner sealing layer, is provided by regulating the temperature during the application of the homogeneous layer 3 so that an appropriate adhesion is obtained. power.
Når emballagematerialet ifølge opfindelsen anvendes til tilvirkning af emballagebeholdere, kan det behandles på konventionel måde, og der behøver ikke 30 tages særskilte hensyn til emballagematerialets specielle egenskaber. Dette medfører, at de af emballagematerialet tilvirkede emballagebeholdere kan være af konventionel type og fremstilles af emballagemateriale i ark- eller baneform.When the packaging material according to the invention is used for the manufacture of packaging containers, it can be treated in a conventional manner and no special consideration has to be given to the special properties of the packaging material. This means that the packaging containers made of the packaging material can be of conventional type and manufactured from packaging material in sheet or sheet form.
