Definitions
- the invention relates to a fibre-based container according to the preamble of claim 1.
- Beverage containers made of coated cardboard have been known from the prior art in the field of composite beverage cartons since the 1960s. Before the cardboard is folded into a container and glued or welded, it is coated with polyethylene and aluminum, for example, to create a composite material.
- beverage cartons protect light-sensitive liquids and also have good barrier properties.
- the polyethylene is used as a liquid barrier and the aluminum is used as a light and oxygen barrier, while the cardboard provides the mechanical stability. Areas where the cardboard is folded, protruding, glued or welded are not only a visual problem, but also weak points in the cardboard packaging.
- beverage cartons have the disadvantage that they do not allow any internal pressure, since they can tear open and become leaky when internal pressure occurs. This means that neither carbonated drinks can be bottled nor can the filled liquid be gassed under overpressure.
- cambered surfaces such as those found in the shoulders of many beverage cartons, are only possible by inserting and welding a plastic part without a carton.
- the flat surfaces immediately bulge outwards under pressure, rendering the container unacceptable for typical use long before bursting.
- polyesters are to be used in some carton packaging in the future, especially PET.
- PET has a good barrier against oxygen and contaminants such as mosh and moah, as well as BPA and BPS.
- PET unlike polyolefins, has little or no creep and would be suitable for internally pressurized beverages, the currently common carton with welded layers is not suitable for internally pressurized applications as it is sensitive to internal pressure and tends to burst.
- the typical flat surfaces deform unacceptably under pressure and render the packaging unusable even before it bursts.
- the invention is characterized in that the shell is at least partially coated with a second layer of a partially crystalline polyester and that the partially crystalline tallline polyester is applied in the form of a fluid or powder. Due to the coating of the dimensionally stable shell, the container has good barrier properties against water vapour, oxygen and carbon dioxide, so that carbonated beverages can be filled into them and protective gas can also be applied to them.
- the second layer in the form of a fluid or a powder, a homogeneous layer is formed that is free of defects and the barrier properties are correspondingly high as a result.
- the dimensionally stable cover has no creases or folds, which makes it even easier to produce a homogeneous second layer.
- the second layer is attached to the inside of the shell, which faces the interior.
- the required barrier properties are present directly where they come into contact with the product.
- the first layer is protected from the contents.
- the second layer assumes the function of the barrier between the filling material and the fiber material and the surrounding area.
- the barrier properties are in the range of stretch blow molded PET bottles, although the polyester has no chain orientation achieved by stretching.
- the invention is characterized in that the second layer is built up by spherulitic polyester crystallization.
- the crystallites are spherical, arranged radially symmetrically and are firmly connected to one another via amorphous intermediate areas.
- the formation of spherulites on crystallization nuclei leads in particular to an excellent water vapor and oxygen barrier without the second layer having to be radially or axially stretched.
- the container is pressure-stable at an internal pressure of up to 8 bar shaking pressure, with the pressure stability resulting from the shape and the mechanical properties of the first layer.
- the dimensionally stable casing is protected by the second layer from moisture and other environmental influences that destroy its dimensional stability.
- the shaking pressure corresponds to the CO2 pressure that occurs during a standardized shaking process.
- the shaking pressure is measured, for example, with a CO 2 tester from Steinfurth Mess-Systems GmbH. Due to the high shaking pressure that the container according to the invention can withstand, it is suitable for filling carbonated beverages.
- the high pressure stability of the container also enables it to be gassed after filling. It is preferred if the water vapor barrier (WVTR) of the container has a value of less than 4 g/m 2 d and preferably less than 1 g/m 2 d at 23° C. and 50% RH.
- WVTR water vapor barrier
- the water vapor barrier (WVTR) of the container has a value of less than 15 g/m 2 d and preferably less than 10 g/m 2 d at 30° C. and 80% RH or at 38° C. and 90% RH owns.
- the oxygen barrier (OTR) of the container has a value of less than 1 g/m 2 d and preferably less than 0.2 g/m 2 d at 23°C and 80% RH.
- RH stands for relative humidity.
- the CO2 barrier is expediently defined in that the CO2 initial concentration within the container is between 1 and 10 g/l and within a period of one month does not deviate from the initial value by more than 5% and preferably by no more than 1%. This barrier against carbon dioxide makes the container ideal for storing carbonated drinks.
- the layer thickness of the second layer is less than 0.3 mm and preferably less than 0.1 mm. This allows the second layer to be applied gently.
- the barrier values are sufficiently high for these layer thicknesses.
- the second layer has a bio-based polyester content of at least 80% by weight, the bio-based being defined according to the ASTM D 6866, CEN/TS 16137 and ISO 16620 standards.
- a bio-based container can thereby be provided since the fiber-based first layer is also bio-based.
- the second layer is biodegradable according to the DIN EN 13432 standard. This has the advantage that biodegradable polyesters can be used for germ-induced crystal growth, which enables the good barrier properties.
- the invention is also characterized in that the second layer contains nucleating agents such as talc or CaCO 3 .
- nucleating agents such as talc or CaCO 3 .
- the crystallite melting point of the polyester is less than 245.degree. C. and is preferably between 200 and 180.degree.
- the spherulitic crystallization takes place at temperatures at which the fiber structures of the pressure-resistant shell are not destroyed.
- the container expediently contains degradation accelerators for the polyester, in particular special lye formers for the saponification of the polyester and/or enzymes which separate the polyester. If plastics are present in the pulp, preferably up to 10% by weight, the degradation accelerators can also rapidly degrade these plastics
- the second layer is applied in a powder coating process with a subsequent sintering process or in a spraying process.
- the polyester is modified with a plasma coating to improve the barrier properties of the container.
- the additional plasma coating is preferably a glass coating based on hexamethyldisiloxane (HDSMO) or a "diamond-like carbon" coating based on acetylene. This will ensure that any defects are covered, since the second layer also has a hard layer.
- HDSMO hexamethyldisiloxane
- a diamond-like carbon coating based on acetylene.
- the bio-based polyester is polyethylene terephthalate (PET), polyethylene furanoate (PEF), polyethylene isosorbide terephthalate (PEIT), polylactide (PLA), polybutylene succinate (PBS), poly-s-caprolactone (PCL) or polyhydroxyalkanoate (PHA), in particular is polyhydroxybutyrate (PHB).
- PET polyethylene terephthalate
- PET polyethylene furanoate
- PEIT polyethylene isosorbide terephthalate
- PPA polylactide
- PBS polybutylene succinate
- PCL poly-s-caprolactone
- PHA polyhydroxyalkanoate
- PHB polyhydroxybutyrate
- bio-based polyester is produced in part from CO2 exhaust gases. This makes the fibre-based container particularly sustainable and the CO2 values can be reduced.
- the bio-based polyester is made from biomass which is unsuitable as food.
- This biomass can be wood, algae, sewage, agricultural or forestry waste, faeces, bio-waste from households, agricultural products from overproduction or expired food.
- the polyester of the second layer contains copolymers. The copolymers allow the crystalline melting point to be lowered, which means that the fiber structures of the first layer are neither impaired nor destroyed by excessive temperatures.
- the polyester expediently has a light barrier against UV light, visible light and infrared light, which causes at least a 30% reduction in transmission between a wavelength of 350 and 550 nm, the light barrier preferably being realized by coloring the second layer. This protects vitamins and unsaturated fats in the filling goods.
- the light barrier prevents decomposition reactions that can cause a bad taste or spoilage of the contents.
- the polyester preferably reacts with atmospheric oxygen or preferably contains additives which react with atmospheric oxygen, in particular oxygen scavengers (scavengers) based on oxidation reactions with other polymers, for example polyamide. Before oxygen can come into contact with the product, it reacts in the second layer.
- oxygen scavengers scavengers
- polyester of the second layer is in the linear form, branched as long chain branches and short chain branches, or crosslinked.
- the invention is also preferably characterized in that the container can be obtained by applying the second layer as a powder to the inside of the shell by an electrostatic high-voltage process, for example an ionization process or a corona process, or a triboelectric or an electrokinetic friction process and the container is baked in a sintering furnace, during the sintering process a crystalline phase grows by spherulitic crystallization and the crystallization growth occurs by adding nucleating agent and maintaining the temperature between the glass transition temperature (TG) and the crystallite melting point (Ts).
- TG glass transition temperature
- Ts crystallite melting point
- the container can be obtained by applying the partially crystalline polyester, unsaturated polyester or saturated polyester present as a liquid or gas, to the inside of the shell by means of spraying, single or multi-axis rotational molding, condensation methods and additionally with a plasma Coating can be covered. This results in a particularly homogeneous and error-free second layer, since the powdered or gaseous polyester reaches every part of the casing that is to be coated several times.
- Figure 1 A side view of a partially sectioned fiber-based
- a container is shown in FIG.
- the container 11 can be a bottle, as shown in FIG.
- the loading container 11 has a first layer 13 and a second layer 15 .
- the first layer 13 is formed from compressed pulp, which forms a dimensionally stable shell 17 and encloses an interior space 19 .
- a pulp is typically understood to mean a mixture of water, fibers (especially paper fibers) and a binder.
- the shell 17 is coated with the second layer 15 at least on the side facing the interior space 19 .
- the second layer is formed from a partially crystalline polyester, which is applied to the shell 17 as a fluid or powder. Due to the partially crystalline structure, the second layer can optimally fulfill the function of the barrier between the filling material and the fiber material and the environment.
- the first and the second layer therefore act as a composite material, in which the individual layers 13,15 meet different Liche tasks in order to obtain a fluid-tight and pressure-stable container n.
- the second layer 15 is also applied to the outside of the cover 17, it can protect the cover from the environment. This is especially useful when the container is used in a humid environment, such as a bathroom, and needs to be protected from the moisture.
- the container 11 can be closed with a screw cap 21 having an internal thread 23 .
- the screw cap 21 can be screwed onto the container neck 25 and be unscrewed from it.
- An external thread 27 is formed on the first layer 13 of the container neck 25 and interacts with the internal thread 23 .
- the external thread 27 of the container can be coated with the second layer 15 .
- the coating with the second layer 15 gives the external thread 27 additional mechanical stability and does not tear out when the screw cap 21 is screwed on.
- Feet 29 can be formed on the outside of the dimensionally stable shell 17 so that the container has a stable stand.
- the combination of the first and second layer 13,15 makes it possible for the container to withstand a shaking pressure of up to 8 bar.
- the container 11 is therefore suitable for bottling carbonated beverages such as mineral water or beer.
- the pressure stability results from the shape and the mechanical properties of the first layer 13 and the second layer 15 prevents the first layer 13 from being weakened by the filling material and the environment.
- the shaking pressure corresponds to the CO2 pressure that occurs during a standardized shaking process.
- the shaking pressure is measured, for example, with a CO 2 tester from Steinfurth Mess-Systems GmbH.
- the second layer 15 is preferably built up by spherulitic crystallization. This results in the following barrier properties, which make the container 11 suitable for filling or storing carbonated beverages.
- the water vapor barrier rate (WVTR) of the container has a value of less than 4g/m 2 d and preferably less than 1g/m 2 d.
- the water vapor barrier (WVTR) of the container has a value less than 15 g/m 2 d and preferably less than 10 g/m 2 d.
- the oxygen barrier (OTR) of the container has a value of less than 1 g/m 2 d and preferably less than 0.2 g/m 2 d at 23°C and 80%RH.
- the CO2 barrier is defined by the fact that the initial CO2 concentration within the container is between 1 and 10 g/l and does not deviate from the initial value by more than 5% and preferably no more than 1% within a period of one month. These barrier values result from a layer thickness of the second layer of less than 0.3 mm and preferably less than 0.1 mm.
- the present container is therefore excellently suited for filling carbonated beverages, the second layer 15 also being bio-based and biodegradable.
- the second layer has a bio-based polyester content of at least 80% by weight, the biobase being defined according to ASTM D 6866, CEN/TS 16137 and ISO 16620 standards.
- the biodegradability of the second layer is defined by the ASTM D 6866, CEN/TS 16137 and ISO 16620 standards.
- the polyester of the second layer 15 has a light barrier against UV light, visible light and infrared light, which causes at least a 30% reduction in transmission between a wavelength of 350 and 550 nm, the light barrier preferably being realized by coloring the second layer .
- This light barrier allows vitamins and unsaturated fats in the beverages to be protected over a long period of time and not degraded or destroyed.
- a spherulite-forming polyester By using a spherulite-forming polyester, a second layer 15 with high crystalline proportions can be formed. As a result, the second layer 15 and thus also the container 11 has very good barrier values. Polyesters that can form spherulites can also be bio-based and biodegradable.
- the casing 17, made from a pulp, provides the pressure stability.
- the container 11 according to the invention not only has such high barrier values that it is suitable for holding carbonated beverages, but it also withstands such a high shaking pressure that an increased internal pressure cannot deform it.
- the container 11 is made of a first and second bio-based layer 13, 15 and is biodegradable.
