Description

Packaging with improved water vapor permeability

The invention relates to a packaging material made of plastic with a water vapor permeability> 15 g / (m ^{2 *} d), the outer surface is at least partially surrounded by an adjoining the packaging material outer surface equipment and identification means with a water vapor permeability <15 g / (m ^{2 *} d) ,

State of the art

Plastic containers are in manifold form and design as packaging for

Transport and storage of a variety of different packaged goods used.

In the case of a large number of packaged goods, it is necessary for the plastic packaging material to provide a sufficient water vapor barrier in order to prevent moisture from penetrating through the packaging material walls toward the packaged goods or out of the interior of the packaging material into the environment.

In the former case, clumping may occur, for example, in the case of scatterable packaged goods, so that a convenient removal of such damaged packaged goods from the packaging material is no longer guaranteed. Furthermore, the packaging material can also be chemically changed by the penetrating water vapor. For example, penetrating water vapor causes a deactivation or degradation of bleach and / or enzymes in detergent and cleaning agent powders. Also undesirable biological effects, such as the growth of bacteria or mold in the packaged goods, are possible by an increased occurrence of water vapor.

In particular, in the case of aqueous packaged goods, on the other hand, an insufficient water vapor barrier can lead to a thickening of the packaged goods if water vapor can escape into the environment through the packaging wall. For such packaged goods, this is particularly relevant in warm temperatures or direct sunlight. This then leads to a changed flow behavior and concentrations in the liquid packaged goods, whereby a precise dosage for the user is difficult. Due to the escaping water vapor, it may be due to the associated Volume loss come to a denting of the corresponding container, which is undesirable for esthetic reasons.

Furthermore, due to the loss of liquid, soluble components of the liquid product may also precipitate and settle to the bottom of the packaging. Finally, the creeping decrease in level associated with the escape of water is undesirable in the bottle, especially if the bottle is transparent and a low level level can be sensed by the consumer.

For the sake of resource conservation and the associated cost reduction usually far material savings in the formation of plastic packaging materials are required. This usually leads to lower wall thicknesses of the packaging, which regularly leads to a reduction of the water vapor barrier of such a packaging means and to a reduction in the stability, in particular the stackability.

This is particularly critical for plastics of non-fossil origin, such as in plastics based on starch or polylactic acid, which generally have a relatively high water vapor permeability, so that they sogg. Bio-plastics are not suitable today for many packaged goods.

Usually, renewable, ie renewable resources are used for the production of such bio-plastics. In addition to the possible use of each regionally available agricultural raw materials for the production of bio-plastics, another advantage is that they are biodegradable according to intended use in a relatively simple and rapid manner, for example by composting according to DIN EN 13432, so that in general further use and widespread use of bio-plastics is desirable.

To improve the water vapor barrier such bio-plastics has been proposed in many places in the prior art to dampen for example with SiO _x or aluminum, so that, consequently, the entire surface of thereof shaped packaging means has a corresponding coating. In particular, the evaporation with aluminum, however, has a number of disadvantages. On the one hand, a metal vapor-deposited plastic film loses its transparency and, on the other hand, they are usually unsuitable for use in a household microwave, so that an application for packaging and preparation of hot food regularly eliminates. In addition, the vapor-deposited layer does not contribute to an increase in the structural stability of the molded container.

Furthermore, bio-plastics vapor-deposited with metals or SiO _x with increasing metal or SiO _x concentrations significantly lose their inherently good biodegradability. Especially in the case of metal-coated bio-plastics it has to be critically questioned whether the introduction of metals like aluminum into the environment, which are usually not naturally degraded but only accumulated, makes sense from an ecological point of view, especially against the background of the latest research results indicate a direct association of diseases such as Parkinson's disease or Alzheimer's disease with increased exposure to bioabsorbable aluminum.

Another, still limiting factor in the use of bio-plastics is their comparatively high price, which is the task, especially when using bio-plastics, to use the smallest possible amounts of such expensive plastic to form a desired packaging so that it can be manufactured at a competitive price compared to conventional plastics. Here, however, it becomes apparent that the demand for the lowest possible use of primary materials for bio-plastics, the need to ensure sufficient permeability to water vapor, the provision of sufficient stability of the packaging and good biodegradability of the packaging material are in direct contradiction to each other and not yet is satisfactorily resolved.

Task:

The object of the invention is therefore to improve the water vapor barrier of a plastic packaging material with the lowest possible use of primary material in a resource-conserving, cost-effective and easy to manufacture manner, wherein the packaging material has sufficient structural stability, in particular stackability.

The object is achieved by a packaging with the features of claim 1. - A -

The advantages of the invention are on the one hand an improvement in the water vapor barrier properties while at the same time possible reduction of the necessary material use of plastic materials. Furthermore, a reduction of plastics of fossil origin to a minimum while increasing the proportion of bio-plastic can be achieved.

Furthermore, the plastic packaging material according to the invention ensures a sorted separation of biodegradable plastic materials and plastic materials which are difficult or impossible to biodegrade after use of the packaging material.

The exclusive use of technologically established methods for producing the packaging means that the packaging material according to the invention can be manufactured inexpensively.

The packaging material according to the invention is particularly suitable for filling, storage, transport and dispensing of flowable or spreadable products, in particular for fillers from the group of textile washing, - cleaning and care agents, dishwashing detergents, personal care products, pharmaceuticals, agricultural auxiliaries, building materials, dyes, adhesives or food.

packaging

The invention is particularly suitable for substantially dimensionally stable plastic packaging material such as, for example, cups, cans, buckets, barrels, bottles, canisters, cans, drums or tubes. However, it can also be used in principle for flexible containers such as bags or sacks.

The packaging can take any form. Round or rounded cross-sectional shapes are advantageous, since "sharp edges" formed on a packaging material lead to undesirable stress peaks in the enveloping film-like equipment and marking means and thus can cause unintentional tearing of the film-like equipment and identification means. Thus, the equipment and identification means easily rests against the surface of the packaging, the contour of the packaging should be as flat as possible. However, it is possible that equipment and identification means in such a way that it follows the contour of the packaging tight-fitting.

Particularly advantageous are rotationally symmetrical packaging forms.

Cups, cans and barrels

A cup in the context of this application is a substantially dimensionally stable container for receiving a flowable or pourable product, which has a filling volume formed by a bottom and a jacket, wherein the cross section of the bottom substantially corresponds to the cross section of the cup opening.

In particular, cans may be a pruned can, a can, a can lid, a retracted can, a fold lid can, a fold lid fill can, a folded can, a drawn can, a can, a siphon, a tearing can, a sippy can, a slip lid can, or a stepped can.

Barrels may be selected from the group of belly drums, stave casks, caissons, garage barrels, semi-cauldrons, pack barrels, reel drums, heavy barrels, bead drums or roll bead drums.

bottle

A bottle in the context of this application is a closable, substantially dimensionally stable container for receiving a flowable or pourable product, which comprises a formed by a bottom and a jacket filling volume, wherein the filling volume through a through the shell in the form of a towards the opening tapered bottleneck shaped opening can be filled or emptied, wherein the cross section of the bottom is greater than the cross section of the opening.

For example, a bottle may be an aerosol bottle, a look-through bottle, a beverage bottle, especially ale bottle, goitre bag, goitre bottle, flail bottle, stony bottle, stubby bottle, vichy bottle, wide neck bottle, as well as mega plate bottle, squeeze bottle, dropper bottle, packaging bottle like something a bottle.

The wall thickness of the bottle is chosen so that the bottle is substantially dimensionally stable. In one embodiment of the bottle, the walls or the lateral surface be elastically deformable to exert a pressure on the products contained in the bottle and thereby to assist the dispensing of product from the container.

The bottle may be formed in a further advantageous embodiment of the invention as a two- or multi-chamber container. Advantageously, the chambers then each contain different products from each other. For example, it is possible to store a liquid product in one chamber and a granular product in another chamber. Other conceivable combinations are listed in the following table:

In a further embodiment of the invention, the closure of the bottle is covered by the equipment and identification means at least partially or in sections. As a result, for example, a tamper-evident seal or closure can be realized in a simple manner.

bag

For the purposes of this application, a flexible packaging means is a packaging material which substantially alters its shape even under light load when used as intended. In particular, the flexible packaging is designed as a bag or sack.

The bag may be selected from the group of bottom bags, block bags, block bags, block bottom bags, block bottom bags, floor bottom bags, bottom fold bags, cross bottom bags, round bottom bags, stand-up pouches, double bags, window bags, flat bags, flap bags, flap pocket bags, conical bags, tubular bags, gusseted bags, pleated bags, sealed edge bags, Triangular seal bag, two-seam bag, flap flap bag, carrying bag and / or valve bag. The bag may be selected from the group of single-use bags, sack bags, pleated bags, flax sacks, cross-bottom sacks, multi-layer sacks, round bottom sacks and / or valve sacks.

Packaging material of the packaging

The packaging material according to the invention is molded from a plastic. The packaging material formed from plastic has a water vapor permeability of more than 15 g / (m ^{2 *} d).

Suitable packaging materials for the packaging material can be selected, for example, from the group of polyolefins, polyethylene terephthalates, acrylonitrile-butadiene-styrene copolymers, cellulose acetates, ionomers, polyacrylonitriles, polyamides, polycarbonates, polyesters, polystyrenes, polyterephthalic acid esters, polyurethanes, polyvinyl alcohols, polyvinyl chlorides.

It is particularly advantageous to select a packaging material from the group of bio-plastics, which are essentially produced from renewable, renewable resources. These can be selected from the group of cellulose-based plastics, plastics based on polylactic acids (PLA), polyhydroxybutyrates (PHB), polyhydroxyvalerates (PHV), polyhydroxyalkaronates (PHA), thermoplastic starch blends, polycaprolactones (PLC).

It is particularly advantageous to form the packaging from a P LA plastic. On the one hand, PLA has a high level of transparency, which means that the PLA-formed packaging has a visually attractive and attractive appearance; on the other hand, PLA has a sufficiently high degree of rigidity and can be processed on standard molding machines.

For ecological reasons, it is advantageous that the packaging material can biodegrade in a simple and as complete as possible manner.

It is also conceivable that the plastic blends used are mixed with shares of plastic recyclates.

In order to further reduce the weight of the packaging material and thus the primary material requirement, it may be advantageous to produce the packaging material from foamed plastics. Equipment and labeling

An equipment and identification means in the context of this application is a film-like packaging aid which is suitable for enclosing the packaging material, at least in sections, in such a way that it bears against the outer surface of the packaging material. The equipment and identification means forms a hose, which encloses the lateral surface of the packaging tightly.

Attachment in this context means that the equipment and marking means with its surface facing the packaging material touches the outwardly oriented surface of the packaging material, whereby the intermediate arrangement of an adhesive layer between packaging material surface and equipment and identification medium surface is also included.

The equipment and identification means is formed from a film which has a water vapor permeability <15 g / (m ^{2 *} d). In a further embodiment of the invention, the equipment and identification means has an E-modulus> 200 N / mm ² .

The equipment and marking means as well as the packaging means are configured in such a way that good physical contact between equipment and identification means and the packaging means is permanently ensured and the equipment and identification means are not easily damaged during handling of the packaging means.

The connection between the equipment and identification means and the packaging can be formed non-positively, cohesively and / or positively. A frictional connection can be realized, for example, by shrinkage or stretching of equipment and identification means relative to the packaging. A cohesive connection can be effected by an adhesive bond.

The film-like equipment and marking agent preferably has a thickness of between 5 μm and 100 μm, more preferably between 7.5 μm and 75 μm, particularly preferably between 10 μm and 60 μm.

The ratio of the packaging material jacket thickness to the thickness of the equipment and identification means is preferably> 1. Particularly preferred is the ratio of Packing jacket thickness to the strength of the equipment and identification means> 1, 5 and <100.

The film can be, for example, a coextruded film, an expansion film, an extrusion film, a flat film, a stretched film, a cast film, a calender film, a foam film, a tubular film or a blown film or a film Shrink film act.

It is preferable to arrange the equipment and identification means single-layered around the packaging material.

In a further advantageous embodiment of the invention, the equipment and identification means is detachably arranged on the packaging. As a result, the equipment and labeling center can be easily solved by packaging and disposed of separately, so that, for example, consisting of a readily biodegradable biodegradable plastic packaging material composting, while the equipment and labeling of a plastic film of fossil origin of thermal utilization is supplied.

The equipment and identification means may be fixed by one or more cohesive connections to the packaging. The cohesive connection can be configured such that the cohesive connection is destroyed during the release of the equipment and identification means from the packaging and can not be restored, so that the equipment and identification means no longer removed by the original cohesive connection to the packaging after its removal from the packaging liable. However, the cohesive connection can also be designed such that a repeated release and adhesion of the equipment and marking means is made possible on the cap.

The cohesive connection can be selected, for example, from the group of adhesive bonds, welded joints or sealing compounds.

It is particularly advantageous if the adhesive layer used provides a water vapor barrier. Thus, it is also conceivable that the water vapor barrier of the adhesive layer is greater than the water vapor barrier of the overlying the adhesive layer equipment and marking agent. In this case is It is advantageous to form the adhesive layer closed area between equipment and identification means and packaging.

In order to facilitate the detachment of the equipment and marking means, an opening aid may be provided on the equipment and identification means, which allow the removal of the equipment and marking means without the aid of opening means, such as a pair of scissors or a knife.

Such opening aids can be designed, for example, as a perforation, tear-off tab, tear tape, tear-open thread, tear-open tab, tear-open seam, scribe tear-open line or trunk tear strip.

The equipment and identification means may completely enclose the packaging.

It is particularly advantageous that the equipment and identification means substantially completely surrounds the lateral surface of the packaging means, the bottom of the packaging material remaining substantially unenclosed by the equipment and identification means. In a further preferred embodiment of the invention, between 50-95% of the surface of the packaging material is covered by the equipment and identification means. It is particularly preferred to cover between 65-90% of the packaging material surface with the equipment and labeling means. As a result, on the one hand, sufficient water vapor permeability is realized for a large number of possible applications and, on the other hand, a sufficiently large supporting effect against buckling or buckling of the packaging material, in particular during stacking, is effected.

The equipment and identification means may also reduce the escape of bad odors, such as may occur in the use of plastic blends with a Recyclatanteil, from the plastic material into the environment.

Advantageously, the ratio of lateral surface of the packaging material to the surface of the head and the bottom is selected to be greater than 2, so that when wrapping the lateral surface with an equipment and identification means with a high water vapor barrier, the water vapor permeable area of the lid and bottom surface in the ratio small fails. It should be noted that more surprising Way a water vapor exchange over the bottom surface, if at all, then takes place only to a very limited extent, since the weight of the filled packaging material causes a seal of the bottom surface relative to the ground.

Shawl label (Shrink-Sleeve)

The shrink label is understood to be a stretch-pretreated thermoplastic film which shrinks or contracts due to the action of heat.

The stitching label and the packaging are configured in such a way that a good physical contact between the shrink label and the packaging is permanently ensured. Preferably, the visual rummaging label should be within the

Temperature range of about 50 ⁰ C to 90 ⁰ C in an amount of at least 5% in

Direction of orientation and shrink with sufficient force to give a tight-fitting, tight-fitting skin around the enclosed within the envelope packaging.

Stretch film or stretch label

A stretch label is understood to mean a film with a tendency to stick, which can be stretched by hand or by machine, placed tightly around the packaging.

The stretch label and the packaging are configured in such a way that a good physical contact between the stretch label and the packaging is permanently guaranteed. Preferably, the stretch label should be of preferably stretchable materials and contract with sufficient force to provide a tight, tight-fitting skin around the packaging material enclosed within the wrap.

Packaging material Equipment and labeling

The equipment and marking means is molded from a packaging material having a water vapor permeability of less than 15 g / (m ^{2 *} d). Preferably, the packaging material of the equipment and marking agent has an E-modulus> 200 N / mm ² .

The packaging material of the equipment and marking agent should have good printability. The packaging material can be substantially printed over the entire surface and thus formed substantially opaque, whereby it forms a correspondingly good UV barrier, the contents of the packaging from UV radiation from the environment protects. This is particularly advantageous for packaged goods with UV-sensitive ingredients, such as enzymes, vitamins, dyes or fragrances etc.

The packaging material may also contain special UV barrier substances and / or UV stabilizers. This can be particularly advantageous when using too large a proportion of transparent equipment and marking agent in order to protect a UV-sensitive packaged goods. The use of UV barrier substances in the equipment and marking agent also has the advantage that in the equipment and labeling comparatively less UV barrier substances for a defined UV barrier effect must be introduced as in the packaging material, so that the corresponding UV barrier is less expensive to produce.

However, it is also conceivable that the surface of the packaging printed and surrounded by a transparent equipment and identification means.

Suitable packaging materials for the equipment and marking agent may for example be selected from the group of polyolefins, polyethylene terephthalates, acrylonitrile-butadiene-styrene copolymers, cellulose acetates, ionomers, polyacrylonitriles, polyamides, polycarbonates, polyesters, polystyrenes, polyterephthalic acid esters, polyurethanes, polyvinyl alcohols, polyvinyl chlorides. In particular, the packaging material for the equipment and marking agent may be a polyethylene or polypropylene.

In order to realize a particularly good water vapor barrier and modulus of elasticity, it is also possible to use multilayer and / or composite films as equipment and identification means. Particularly preferred are multilayer films or composites consisting of PET-AI-PE, PET-PE or BOPP-PE.

Packqut

When using the packaging according to the invention are flowable and free-flowing

Packaged goods particularly preferred.

In particular, it is advantageous that the ratio of filling level of the flowable or pourable packaged goods to the height of the lateral surface of the packaging material is greater than 0.5, preferably greater than 0.75. This ensures that the packaged goods exert sufficient, outwardly directed pressure on the lateral surface of the packaging, so that the lateral surface is not pressed by the force of the packaging means enclosing equipment and marking means inward. The pourable packaged goods may in particular be detergent powder, detergent granules, detergent powder, detergent granules, salt or the like.

The flowable packaged goods are preferably liquid or gel detergents and / or cleaners, personal care products, adhesives, building materials or the like.

In the following the invention will be explained in more detail with reference to exemplary embodiments illustrative drawings. In this case, particularly preferred embodiments and particularly preferred combinations of features are further described in detail. It shows:

1 shows a bottle 1 formed as packaging material with a bottom 3 and a head

2 on which the shutter 7 is located and a hull 4, which is located between the ground

3 and head 2 extends. The bottle 1 has a waist approximately in the middle height of the bottle 1. The hull 4 is enclosed by a foil-like equipment and identification means 5, which is adapted to the contour of the hull. As can be seen from FIG. 1, areas at the bottom 3 and head 2 are not covered by the equipment and identification means 5. In order to realize a user-friendly detachment of the equipment and identification means 5, a vertically extending to the bottle bottom 3 opening aid 6 is provided on the equipment and identification means 5, which may be formed for example as a perforation.

Another embodiment of the known from Fig. 1 bottle 1 is shown in Fig. 2. In this case, the equipment and identification means 5 completely spans the entire hull surface 4 of the bottle 1, as well as the lower part of the closure 7, so that the closure 7 can not be detached from the bottle 1 without destroying the equipment and identification means 5. Thus, a tamper-evident closure is formed by the equipment and identification means 5. In order to facilitate detachment of the closure 7, the equipment and identification means 5 with an opening aid 6, such as a perforation, is provided in the lower region of the closure 7.

The closure 7 may also be formed as a dosing aid, such as a trigger spray head. This is shown by way of example in FIG. 3.

Fig. 4 shows a cylindrical plastic can 1 around the hull surface 4 is a equipment and identification means 5 is placed. As can be seen in FIG. 5, a tab 8 can be arranged on the equipment and identification means 5, which tab projects substantially radially from the fuselage surface 4 and is the carrier of information perceivable by a user. The tab 8 can, for example by a perforation, be detachably arranged on the equipment and identification means 5. The tab 8 may also be formed as a carrying aid, which is exemplified in Fig. 6. The tab 8 in this case has a handle hole. 9

In Fig. 7 designed as a plastic box packaging 1 is shown with a rectangular basic shape, the fuselage 4 completely from the equipment and Identification means 5 is enclosed. The packaging means 1 has on a side wall of the hull 4 an opening aid 7 for a product removal flap, dosing chute or the like. This opening aid 7 is formed for example as a perforation or scribe line and completely covered by the equipment and identification means 5. The equipment and identification means 5 has in the area of the opening aid 7 an opening aid 6, with which a part of the equipment and identification means 5 can be dissolved out of this, so that the opening aid 7 is accessible to the user.

A further embodiment of the known from Fig. 7 plastic box 1 is shown in Fig. 8. In this embodiment, the head 2 of the plastic box 1 is completely enclosed by the equipment and identification means 5. From the equipment and identification means 5 extends in the head area designed as a carrying aid 8 tab having a handle hole 9.

Another, not shown in the figures embodiment of a PLA bottle with a stretch or Seh rümpf label will be described below.

The PLA bottle described and used below is a 500 ml bottle from BELU for "Natural Mineral Water UK" Production code: 25061819. The bottle has a cylindrical shape and a height of 220mm.

One group of BELU PLA bottles was wrapped in a PET sleeve from Klöckner called Pentaplast Thermodurr SF-E 649/15. The bottom of the bottle remained uncovered from the sleeve, the coat was completely sleeved up to the closure (200mm).

Another group of BELU PLA bottles is provided with a P E-Sch rümpf the brand label Flex ^® -strech Around the Fa. Been provided with a thickness of 65μm Bischof + Klein GmbH. The P E foam label was sleeved to a height of 150 mm onto the PLA bottle, whereby the bottom of the bottle remained uncovered by the sleeve.

A control group of BELU PLA bottles remained unenclosed. The bottles were filled with a commercial liquid Universal Persyl detergent and stored at 40 ⁰ C in a climatic chamber. The weight loss of the bottles has been recorded over time and is shown in the following table and graph. The measurement was carried out according to the specifications of DIN 53122.

Table 1: Weight curve of the filled PLA bottles

As can be seen from the table and the diagram, the sleeve-encased PLA bottles show a significantly lower loss of water than a bottle without a corresponding sheath.

Furthermore, the PLA bottles were subjected to a compression pressure measurement according to DIN 55526 Part 1. For this purpose, as already described above, first a group of BELU PLA bottles with a PET sleeve and another group provided with a PE shrink label. Again, a control group of BELU-PLA bottles without wrapping remained. In contrast to the storage experiments described above, however, the BELU PLA bottles remained unfilled for the compression pressure measurement. The PLA bottles were positioned between the platen of a press with the plates moving toward each other at a speed of 10mm / min. The force was measured at a deformation of 3 mm (F 3 mm [N]) and 5 mm (F 5 mm [N]).

Table 2: Compression pressure measurement of the sleeved PLA bottles

It can be seen the significant increase in compression pressure by the use of an enclosure according to the invention in comparison to the non-sevaged PLA bottle.
