Definitions
- the present invention relates to a packaging container possessing superior storage stability on storage in a storage medium containing liquid, the packaging container being produced from a laminated packaging material comprising a core layer of a fibre material with a layer of plastic applied on the outside of the packaging container.
- the present invention moreover relates to the use of the packaging container for storage of liquid foods in a cold storage medium containing liquid.
- a large group of packaging materials for such single-use disposable packages comprises a core layer of paper or paperboard and outer, liquid- tight layers of polyethylene, normally low density polyethylene (LDPE).
- LDPE normally low density polyethylene
- the composition of such a packaging material is intended to impart to the packed product the best possible product protection properties, at the same time as it is to render the package easy to produce and easy to handle.
- a core layer of paper or paperboard imparts to the package good mechanical configurational stability so that the package may be distributed and handled in a simple and rational manner.
- the outer, liquid-tight coatings of polyethylene protect the core layer against moisture and liquid.
- the packaging material may also include different metal layers or plastic layers possessing barrier properties against light or gases, such as for example oxygen gas.
- Such packaging containers are often produced in that a web of packaging material is reformed into a tube by the longitudinal edges of the web being united with one another, whereafter the tube is filled with the intended contents and sealed along narrow, transverse mutually spaced apart sealing zones.
- the thus sealed-off portions of the tube containing their contents are thereafter separated from the tube by means of incisions in the above-mentioned sealing zones and are formed by folding into optional geometric configuration, depending on how the sealing joints or seams are oriented.
- the above-described packaging container is normally not subjected to extremely damp or humid conditions for any length of time, for which reason it is often sufficient to coat the core layer with one layer of LDPE on both sides.
- the climatic conditions are such that cooling is required both during transport and during storage, at the same time as access to refrigerated transport facilities and refrigerated storage facilities is limited in certain areas. It is then common to cool food products with ice in boxes or crates of a thermally insulating material. With the passage of time, the ice melts so that the coolant gradually comes to consist of a mixture of ice and water, and finally of water alone.
- packaging containers of the above-described type after a certain storage time, lose configurational stability and so-called grip rigidity properties because of the fact that exposed incision edges of the core layer (which gives the packaging container its configurational stability and rigidity) absorb water and become soft and sloppy.
- a lengthy period of storage at high relative humidity, such as between 80 and 100% RH also has the effect that the fibres in the core layer absorb moisture so that the stability properties of the packaging container deteriorate.
- One object of the present invention is therefore to realise a novel packaging container of the type described by way of introduction which does not suffer from the inherent drawbacks of the type intimately related with the prior art technology.
- a further object of the present invention is to realise a packaging container of the above-described type which, on storage in a cold storage medium containing liquid, possesses superior storage stability, i.e. almost totally retains its superior configurational stability and grip rigidity properties, even after a lengthy storage period.
- Yet a further object of the present invention is to realise a packaging container of the above-described type which, on storage in high relative humidity, of the order of between 80 and 100% RH, almost totally retains its superior configurational stability and grip rigidity properties, even after a lengthy storage period.
- the core layer By coating the core layer with a thicker and more rigid layer of a plastic selected from a group consisting of polypropylene, high density polyethylene (HDPE), and polyester instead of LDPE, better protection will be obtained against the penetration of liquid and moisture into the core layer, at the same time as such a layer of the above-mentioned polypropylene, HDPE or polyester contributes, because of its superior rigidity properties, to such a laminated packaging material - seen as a whole - also obtaining improved rigidity properties.
- a plastic selected from a group consisting of polypropylene, high density polyethylene (HDPE), and polyester instead of LDPE
- the plastic layer consists of an oriented polypropylene, oriented HDPE or an oriented polyester and, according to one preferred embodiment of the present invention, of a biaxially oriented polypropylene, biaxially oriented HDPE or a biaxially oriented polyester.
- the type of polymer is selected such that the combination of its rigidity properties and moisture barrier properties with a suitable layer thickness entails that the packaging container may be stored in a liquid without appreciably losing its configurational stability and grip stability properties.
- a film of an oriented or biaxially oriented polypropylene, HDPE or polyester is laminated onto the core layer by the intermediary of the extrusion of a thin interjacent lamination layer of, for example, polyethylene.
- the packaging material often includes additional layers with light barrier properties or gas barrier properties, for example against oxygen gas.
- a layer is applied on that side of the core layer which is turned to face towards the inside of the packaging container, but may also be applied on the other side of the core layer.
- a barrier layer may consist of a metal layer such as, for example, an aluminium foil or a thin layer of metal or metal oxide such as, for example silicon oxide (SiOx, where x is 1.5 - 2.2), which has been deposited on a plastic layer of oriented polypropylene, HDPE, or oriented polyester.
- the gas barrier layer may consist of a plastic layer comprising a polymer possessing superior gas barrier properties such as, for instance, ethyl vinyl alcohol (EVOH) or polyvinyl alcohol (PVAL).
- incision edges In order further to protect the packaging container against the penetration of moisture and liquid, it is possible to protect incision edges (if any) which occur on the outside of the packaging material of the packaging container against exposure to water. Such protection is realised in a per se known manner by coating or impregnating the incision edges with a mechanically or chemically water-repellent agent.
- the incision edges may be covered with a plastic strip which is laminated or glued in place on the packaging material around each respective incision edge, or these incision edges may be impregnated with a hydrophobic liquid substance such as, for example, an oil or a fat of some type.
- Incision edges in overlap joints may alternatively be folded in under the overlapping packaging material so that they are not exposed to surrounding moisture or liquid.
- FIG. 1 schematically illustrates a preferred packaging material according to the present invention
- Figs. 2a and 2b show how the flexural strength and moisture content respectively, in a packaging material according to Fig. 1 in a packaging container produced from the packaging material varies with storage time in water at 5°C;
- Figs. 3a and 3b show how the flexural strength and moisture content, respectively, in a packaging material according to Fig. 1 in a packaging container produced from the packaging material vary with storage time in high relative humidity, i.e. between 80 and 100% RH.
- Fig. 1 thus schematically illustrates an example of a packaging material according to the present invention carrying the generic reference numeral 10.
- the laminated packaging material comprises a core layer 11 of, for example, paper or paperboard of a conventional packaging quality.
- the layer 12 may, for example, be laminated to the core layer by the intermediary of a thin, extruded plastic layer 13 of, for example, polyethylene.
- BOPP is, for example, suitably coated on both sides with a thin layer 14;15 of an adhesion-promoting or thermosealable polymer.
- a thin layer 14;15 of an adhesion-promoting or thermosealable polymer On that side of the core layer which, in a finished packaging container, is turned to face in towards the interior, an additional layer 16 may be applied which increases stability, and this layer may moreover possess superior gas barrier properties.
- Such a layer 16 increasing stability may consist of a metal, such as, for example, an aluminium foil.
- such an aluminium foil 16 is laminated to the core layer 11 by the intermediary of extrusion of a thin plastic layer of, for example, polyethylene
- the aluminium layer 16 on the inside of the packaging container is suitably clad with a plastic layer 18 of, for example, polyethylene, this plastic layer moreover being thermosealable.
- the packaging material of the type described with reference to Fig. 1 has been tested on storage in water and at relatively high humidity, such as 80-100% RH, respectively, at 5°C.
- the layer 12 consisted of a film of approximately 18 ⁇ m thick BOPP, which is clad on both sides with a 0.6-0.7 ⁇ m thin layer 14;15 of an adhesion-promoting and thermosealable polymer.
- the film 12 is laminated on the core layer 11 by the intermediary of extrusion of approx. 12 ⁇ m of low density polyethylene (LDPE) and, in the same manner, the aluminium foil is laminated to the other side of the core layer by the intermediary of approx. 25 ⁇ m of LDPE.
- the aluminium foil 16 is clad with approx. 35 ⁇ m of LDPE, 18.
- the core layer 11 consists of a paper of a packaging quality, for example of the type known as so-called liquid paperboard, with a rigidity of 80 mN.
- the tested packaging material 10 has been compared with a packaging material of conventional type with the same configuration as the packaging material 10, but without the film 12.
- the core layer is, thus, coated with an extruded layer of 12 ⁇ m low density polyethylene (LDPE) on that side which is turned to face towards the outside of the packaging container.
- LDPE low density polyethylene
- Parallelepipedic packaging containers of a volume of 250 ml of the Terra Brik® type, produced from the packaging material were test stored for 12 days. Measurements were made on 15 packages in each test after 1, 2, 5 and 12 days.
- Figs. 2a and 3a the flexural strength of the test material 10 according to the invention is as good as totally retained on storage for 12 days in water and air at high humidity, respectively, while the flexural strength of a corresponding conventional packaging container is reduced by approx. 20 per cent after 1 day, and by approx. 30 per cent after 12 days' storage in water, and by approx. 10 per cent after 12 days' storage at high humidity.
- the rigidity of the packaging material in the core layer reduces with increasing moisture content, with the result that the total rigidity of the packaging material is also reduced.
- the core layer is instead laminated with an outside layer of a plastic material which, on the one hand, is rigid in both the machine direction (MD) and in the cross direction (CD), and on the other hand, permits lower moisture penetration than conventional outside layers of polyethylene, the packaging material in its entirety will be more rigid and more stable also in extremely damp conditions.
- MD machine direction
- CD cross direction
- the outer plastic layer selected from a group consisting of polypropylene, HDPE and polyester has a thickness of at least 10 ⁇ m combined with an E-modulus of at least 1000 MPa in both machine and cross directions.
- the above-mentioned outer plastic layer has a thickness of at least 15 ⁇ m and /or an E-modulus of at least 2000 MPa in both the machine and cross directions.
- the above-mentioned outer plastic layer has an E-modulus in the machine and cross direction, respectively, of at least 3000 MPa.
- the rigid outside layer cooperates with the rigid layer on the other side of the core layer - in this case the aluminium foil, and gives an I-beam effect with the interjacent core layer.
- the present invention realises a packaging container which, like a packaging container of plastic or metal, is suitable for cold storage in water or ice and which may be stored in relatively high humidity, i.e. of the order of 80-100% RH, without losing its superior configurational stability and grip rigidity properties, even after a lengthy period of storage.
