- both approaches are not very suitable in practice because they are extremely cost-intensive and time-consuming due to the high cost of the necessary machines, the short machine running time and the high sensitivity of the machines.
- the mechanical properties of the containers that can be achieved in this way are not sufficient for everyday use. The high mechanical loads to which the coated containers are exposed during the normal filling and packaging process and only later in sales and use often lead to a damage to the surface of the barrier layer, which in turn dramatically reduces the gas barrier effect of the barrier layer.
- GB 2 337 470 A proposes to reduce the gas permeability of a substrate, such as a PET bottle, by applying a barrier layer of a first polymer, such as polyvinyl alcohol applies the substrate, and then protects the barrier layer from the environment by applying a protective layer of a second polymer with a molecular weight in the range of 5,000 to 50,000 g / mol.
- a protective layer of a second polymer with a molecular weight in the range of 5,000 to 50,000 g / mol.

- the coloring of the barrier and / or cover layer of the molded plastic body is particularly advantageous inter alia because colored plastic molded bodies can be recycled in a simple manner after the colored barrier and / or cover layer has been detached. In contrast, moldings in which the plastic core is colored have to be sorted out and recycled separately in a complex process.
- the top layer can optionally contain further additives, such as, for example, dispersing aids, waxes, defoamers and plasticizers. These are preferably in an amount of up to 10.0% by weight, advantageously up to 5.0% by weight, in particular in the range from 0.1 to 2.0% by weight, in each case based on the total weight of the Top layer, before.
- the plastic molded body according to the invention is characterized in particular by a permanent low gas permeability, in particular for carbon dioxide and oxygen.
- the gas barrier effect achieved by the coating can be determined using methods known per se. These measurements are usually based either on the measurement of an increase in pressure in a measuring cylinder or on the detection of the gas in question outside the object to be examined (also in a closed cylinder) by means of infrared spectroscopy. Compared to a standard, this results in a factor for the improvement of the barrier property, which is referred to in English as the barrier improvement factor ("BIF").
- BIF barrier improvement factor
- the BIF of an uncoated PET bottle is therefore about 1.
- a BIF of 3 means that the shelf life of the filled product; ⁇ : (CO 2 loss and oxygen penetration) is three times as long as that of an uncoated PET bottle; is three (3) months instead of one (1) month.
- the barrier is not limited to one direction, rather it fulfills two functions at the same time (for example: carbon dioxide remaining in the bottle (barrier to the outside) and Protection against oxidation (oxygen) from the outside (barrier from the outside)). Consequently, the barrier improvement of the present invention means a longer shelf life of the filling, which is also referred to as shelf life. With a BIF of 1 the shelf life is for example one month, with a BIF of 2 this time doubles to 2 months. With higher BIF values correspondingly longer. These examples apply to carbonated, non-alcoholic drinks (colas and lemonades).
- the oxygen barrier in addition to the carbon dioxide barrier, is even more important.
- the BIF should normally be at least 5. This corresponds to a shelf life of 5 months.
- the plastic molded body according to the invention can be produced in a manner known per se, simply and inexpensively. The use of special, complex techniques, such as coextrusion or plasma coating, are required.
- the plastic molded body is preferably first coated with the desired polyvinyl alcohol and then with the composition of the cover layer specified above. In principle, all known coating processes can be used, although immersion, spraying, casting, spraying and / or electrostatic spraying processes have proven particularly useful.
- the polyvinyl alcohol-containing barrier layer is preferably applied from an aqueous solution and then preferably dried in the next step. This is advantageous in order to optimize the application of the following layer, which is optionally applied from a solvent other than water. With wet on wet applications there is a risk of the layers being mixed, which on the one hand adversely affects the barrier effect and on the other hand worsens the visual appearance by leading to clouding. Drying can be done in a variety of ways. It is important that the base material is not changed or even damaged by the drying is (for example, by thermal deformation). In addition to (hot) air dryers, infrared or microwave radiation can also be used for drying.
- the best and cheapest system is based on the requirements for dwell times, throughputs, thermal loads and the like.
- concentration of the solution used depends on the macroscopic properties of the same, and depending on the system there are optimal other areas which are optimal at the temperature used.
- the polyvinyl alcohol concentrations are preferably in the range from 1.0 to 30.0% by weight, particularly preferably in the range from 3 to 20% by weight and in particular in the range from 5 to 15% by weight, based in each case on the Total weight of the aqueous solution.
- the finished, dried polyvinyl alcohol-containing barrier layer is now particularly well able to take up the next cover layer. Nevertheless, it may be particularly advantageous under certain circumstances to increase the adhesion of the cover layer to the barrier layer using a primer.
- the cover layer is preferably also applied by means of the coating technologies described above, the technology selected being able to be different for each layer and not having to be the same for both layers. This also depends on the desired requirements, which have already been described in more detail above. According to a particularly preferred embodiment of the present invention, the composition of the cover layer is applied without using a solvent.
- the cover layer can also be cured by initiating the polymerization of the composition in a manner known per se, for example thermally and or by redox initiation.
- the polymerization is initiated by UV radiation.
- UV radiation Although known to be used in aqueous polyvinyl alcohol UV radiation can lead to a reduction in molecular weight, the polyvinyl alcohol-containing barrier layer according to the invention is not attacked by the UV radiation used for curing the top layer. On the contrary, the high BIF of the coated plastic molding remains unchanged or is even increased slightly.
- the polymerization is initiated by electron radiation (EB radiation).
- EB radiation electron radiation
- the thicknesses of the applied layers depend on the desired properties.
- the layer thickness of the barrier layer is preferably in the range from 0.5 to 10 ⁇ m, particularly preferably in the range from 1 to 5 ⁇ m.
- the layer thickness of the cover layer is preferably in the range from 0.5 to 10 ⁇ m, particularly preferably in the range from 1 to 5 ⁇ m. Even a layer thickness of 2 ⁇ m, in particular 1 ⁇ m of each of the individual layers, is sufficient to achieve barrier improvement factors> 3 with simultaneous water resistance. With a 0.5 1 PET bottle, this generally means a weight gain of only approx. 0.2 g. ' ' . ' '
- a preform which comprises a substrate layer, a barrier layer and a cover layer which contains a crosslinkable compound. This one.
- the preform is then blow molded into a plastic body.
- the cover layer of the molded plastic body is crosslinked.
- preforms are coated, it is advantageous to first select a correspondingly higher layer thickness, since the components are stretched during stretch blow molding. Depending on the desired final layer thickness, ie the desired layer thickness of the barrier and the top layer of the stretch-blown molded body, the barrier layer and the top layer are to be applied correspondingly thicker. In these cases, therefore, multiple (repeated) application of the individual Components or the use of higher concentrations may be advantageous. Since the preforms are usually not immediately processed in a stretch blow molding machine, the speed of the application of the coatings is independent of the speed of the filling system. Therefore, the preforms can also be coated using other techniques, such as dipping.
- the composition of the cover layer is preferably homogeneously stretchable, this property is particularly advantageous when coating preforms which, depending on the size of the stretched container, are stretched by a factor of 10.
- the term homogeneously stretchable means that the maximum layer thickness of the uncrosslinked cover layer of a shaped body stretched by a factor of 10 parallel to the coating is preferably at most 5 ⁇ m, particularly preferably at most 2 ⁇ m and very particularly preferably at most 1 ⁇ m thicker than the minimum layer thickness.
- This property is generally achieved by cross-linkable polymers that are very compatible with the barrier layer. These include in particular the crosslinkable polyvinyl acetals set out above. '
- the glass temperature of the composition of the cover layer is preferably less than or equal to the processing temperature of the substrate layer.
- glass temperature is glass temperature.
- the glass temperature can be determined using differential scanning calorimetry (DSC). This property is particularly advantageous when coating preforms.
- Glass temperature can be estimated using the Fox equation, which is for the purposes of the present Invention applies approximately to all organic polymers which have crosslinking groups, in particular for polyvinyl acetals and / or acrylic polymers.
- the Fox equation is:
- T g is the glass transition temperature of the copolymer
- T g the glass transition temperature of a homopolymer which is prepared from the first monomer of the copolymer
- T g2 is the glass transition temperature of a homopolymer made from the second monomer of the copolymer
- T g3 is the glass transition temperature of a homopolymer made from the third monomer of the copolymer
- X ! is the weight fraction of the first monomer in the copolymer
- "' ; • x 2 is the weight fraction of the second monomer in the copolymer
- "' x 3 is the weight fraction of the third monomer in the copolymer.
- the cross-linked cover layers hardly show a decrease in the barrier improvement factor after mechanical loading by a filling system.
- the barrier improvement factor preferably decreases by a maximum of 20%, in particular by a maximum of 10% and particularly preferably by a maximum of 5%, based on the barrier improvement factor before the mechanical load from a filling system.
- the cross-linked top layer has excellent scratch resistance.
- the scratch resistance can be determined using the Taber test in accordance with DIN 53754.
- the abrasion at a load of 1000 g using Type CS17 friction rollers and a test device from Taber Industries Model 5131 after 600 cycles preferably less than 30 mg, in particular less than 20 mg, particularly preferably less than 15 mg.
- the abrasion is preferably less than 12 mg, in particular less than 8 mg.
- the abrasion is preferably less than 40 mg, in particular less than 30 mg and particularly preferably less than 25 mg.
- the plastic molded body is used for the storage of gas-sensitive foods, advantageously of preferably carbonated beverages, in particular beer and beverages containing beer.

- the coated PET bottles are now filled with water in a filling system. After running through the system, the bottles are assessed for scratches on the top layer and then stored in water for 7 days. After the water has been stored, the quality of the top layer is assessed. The results are shown in Table 1 below.
