Definitions
- Biodegradable materials have been known for some time and are also known biodegradable plastics. These include, but are not limited to, polybutylene succinate, PBS for short, a biodegradable bioplastic made from butanediol (e.g., bio-BDO) and succinic acid, which is also biobased.
- PBS polybutylene succinate
- PBS polybutylene succinate
- a biodegradable bioplastic made from butanediol (e.g., bio-BDO) and succinic acid, which is also biobased.
- biodegradable plastics also includes polybutylene succinate adipate (PBSA), which, in addition to succinic acid, also incorporates adipic acid. Also, this plastic may be more or less bio-based depending on the monomer origin. From DE 10 2007017321 a multilayer film and a method for its production are known and in one of the variants disclosed in this application also comes a thermoplastic polyester, such as e.g. PBS is used, which is used alone or in combination with other thermoplastic polyesters.
- PBSA polybutylene succinate adipate
- DE 10 2013 216 309 A1 discloses a biocomposite or biomaterial with sunflower seed shells / pods, wherein a PLA is used as the plastic component. Also, the measures to certain physical properties, such as brittleness, elasticity, Young's modulus, strength, etc., to adjust such biodegradable plastics, relatively complex and expensive.
- the invention has for its object to reduce the previous disadvantages or even completely avoided.
- the per se known polybutylene succinate (PBS), PBSA or the like is compounded with sunflower husk fibers (these may also be sunflower seed husk fibers) (hereinafter also referred to as SPC PBS or S 2 PC PBSA).
- the sunflower husk fibers are a pure organic product, because the sunflower husk surrounds the oily core of a sunflower seed, it requires the preparation of the sunflower husk fibers only of peeling the seed, the crushing (eg by a grinding process) of the shell material to the desired grain size, and drying to a certain moisture value and the DEALING (reduction) to a desired oil / fat content.
- the crushing of the sunflower husk fiber is carried out by a grinding process, wherein the grain size is in the range of 3 millimeters or less, preferably in the range of 0.01 mm to 1 mm, more preferably in the range of 0.1 mm to 0.3 mm.
- the aforementioned particle size data mean that at least a desired percentage, for example 80 percent or more, of the fiber material has the stated particle size and only small proportions are outside the desired particle size range.
- the invention can significantly reduce the production costs compared with the use of pure PBS, e.g. over 10 percent. This is because the sunflower husk fiber and its preparation is significantly cheaper than the production of the PBS material. Since the sunflower husk fiber is also thermally stable up to a temperature of 200 degrees Celsius, there is no negative sensory influence of a coffee product when it is produced in a coffee capsule according to the invention under relatively high pressure and / or high temperature in a correspondingly suitable coffee machine.
- sunflower husk fiber provides a kind of "bio-fiber reinforcement" for the plastic can also reduce the wall thickness of the capsule compared to pure PBS material, which reduces the amount of PBS used per container, packaging, coffee capsule, etc., and again leads to cost savings.
- the embodiments relate to a biodegradable coffee capsule or to a biodegradable and thus compostable plant container (flowerpot), but is expandable to any biodegradable and thus compostable packaging, containers or the like.
- FIG. 1 to 4 different views of a coffee capsule according to the invention of
- the Tassimo-type coffee capsule a material formulation according to Table 1 was used, for the Nespresso-type coffee capsule a material composition according to Table 2. From both tables it can be seen that 69 percent of the coffee capsule material was formed by a Bio-PBS FZ71 PM (whose data sheet is also attached) and 30 percent of the compounding material was made by shell flour (grain size ⁇ 0.5 and 0.2 mm, respectively) and further an additive (adhesion promoter), namely Licocene PP MA 7452 was used.
- Bio-PBS FZ71 PM used The details of the Bio-PBS FZ71 PM used can be found in the technical data sheet at the end of this description.
- some values stand out, e.g. the value for the modulus of elasticity, tensile strength, etc.
- the better modulus of elasticity makes it easier to pierce the material with thorns or water pressure.
- the holes in the material formed by the spikes or water pressure are important for coffee capsules and known (for conventional capsules).
- the modulus of elasticity can even be increased.
- the requirement for the modulus of elasticity is currently at least 1 150 MPa, which can not be achieved by a pure PBS material.
- the proportion (percentages by weight) of the adhesion promoter so the additive Licocene PP MA 7452 can be changed without that leads out of the invention and it can also be used, other comparable adhesion promoter.
- biomaterial according to the invention formed from sunflower shell meal on the one hand and PBS on the other hand, is that it is completely biodegradable, ie compostable. This means in concrete terms that there is a "home compostability", because the material thus produced can be completely degraded by a corresponding biological environment (compost or soil / soil).
- the material according to the invention has the advantage that the cycle time in the injection molding process, ie when the compound of the invention is used in an injection molding machine to a corresponding end product, eg. As a coffee capsule or a plant pot or the like, to produce, the time in which the material is injected in the injection molding machine and then removed, clearly, d. H. by up to 5 to 10% or more, which significantly increases the efficiency of the entire injection molding process on an existing production facility and thus, in turn, results in a cost reduction.
- a corresponding end product eg. As a coffee capsule or a plant pot or the like
- the invention also provides the sunflower husk meal as a natural humus material, so that overall the biodegradation process is faster than before, because the composting bacteria and microorganisms can thus the entire easily digest material by first of all settling on the sunflower husk meal and then opening up the remaining material.
- shell meal ie the flour from sunflower husk / husk
- the speech it is from the Sonnenblumenschalenma- material by a corresponding milling process, eg. B. an impact mill, by means of which the shell material to the desired grain size or fiber length, z. B. 0.5 mm, 0.2 mm, or the like, is brought,
- the oil content in the shell material of the SPC PBS material is well below 10 percent, z. B. by de-oiling at 6 percent or less, and the residual moisture in the compound material is by drying at less than 1 percent, preferably at about 0.05 percent (or less, but also 0.1% to 0.5% is still acceptable) ,
- biodegradable plastic component instead of PBS and, if necessary, also a further biological fiber, such.
- Wood fiber added to the sunflower fiber PBS compound.
- a wood fiber, hemp or flax fiber is also of the same order of magnitude, e.g. B. 0.1 - 0.5 mm grain size / fiber length and make up 5-10% of the total product, the physical, biological and chemical properties of the SPC-PBS material according to the invention does not change drastically, at least not substantially deteriorate.
- the invention of the present application also encompasses the production of a film as a biomaterial product based on sunflower seed husks or sunflower seed husks with further use of PBS, PBSA or the like.
- This film according to the invention can be produced with known film production machines (normal single-screw extruders).
- the thickness can be between about 200 ⁇ and 1000 ⁇ , with particular preference is a version of about 300 ⁇ .
- the film according to the invention is characterized in that it contains 35% of sunflower human meal (the shell meal in this case has a fiber length / grain size of ⁇ 200 ⁇ ) and in addition with 30% of a mineral filler, for example, but not exclusively, filled with kaolin.
- This slide shows, if they are used as z. B. 300 ⁇ thick sealing film for coffee capsules (for example of the type Nespresso or the like) is used, a particularly desirable fracture behavior.
- this film can be ensured that it breaks only by the water pressure (at predetermined, previously engraved areas) of the coffee machine in the capsule. This is not possible with a conventional plastic film (eg made of PE, PVC, PP or the like) without filler, since this is generally too elastic and can withstand the pressure of the water with it.
- the sealing film used in coffee capsules is thinner than the wall portion (also made of film, for example by injection molding or thermoforming process) which forms the lower part of the coffee capsule (including spout) as a receptacle / cup for the coffee / tea material (see Fig. 4 in side view, Fig. 1 in the top view) wherein a material thickness of z. B. about 500 (or less) ⁇ completely sufficient for the wall area, but this material thickness can be adjusted individually.
- a thin aluminum foil (which is pre-stamped) has been used in many coffee capsules so far as the top closure and thus has break points breakable at predetermined locations by the water pressure.
- aluminum foils are used for the Nespresso-type compatible capsules from third-party suppliers.
- such a coffee capsule is not compostable because aluminum has no composting behavior or degradation behavior in the soil, but on the contrary would contaminate a compost.
- the coffee capsule according to the invention which is provided on the upper side and / or circumferentially with a film according to the invention, characterized by their very good oxygen barrier effect.
- This oxygen barrier effect is ⁇ 50 cm 3 / m 2 * d * bar.
- the above unit means that less than 50 cm 3 of oxygen per day (d) penetrate through a square meter of existing (sheet material) at a bar pressure. If the film is produced in a multi-layer composite in which an intermediate layer of about 30 ⁇ m PVOH or "G polymer" is used, the film can achieve a barrier effect of up to 0.4 cm 3 / m 2 * d * bar.
- a “G polymer” is a modified PVOH material which can be used particularly advantageously for a multilayer composite in which the film material is formed from the biomaterial according to the invention
- the G polymer is from Nippon Gohsei also known as Nichigo-G Polymer "Amorphous Vinyl Alcohol Resin” and described at http://www.nippon-qohsei.com/nichiqo-q-polymer.
- multilayer films for use in coffee capsules are already known and such films are produced in a multi-layer process.
- Such multi-layer methods are also applicable to the film of the present invention using the S 2 PC-PBS material.
- the coffee capsule is prepared in a coinjection process (as known, for example, from WO 2016/071036 or EP 1576 6515), in which the barrier layer consists of PVOH or G polymer.
- the barrier layer consists of PVOH or G polymer.
- This also allows very high oxygen barrier values to be achieved.
- Tables 5 and 6 show a comparison in which various physical parameters of an SPC-PLA material are compared with an SPC PBS material according to the invention. These tables show that an SPC PLA (in the left-hand table in each case) tends to be a very brittle compound which is at the same time very stiff, while the SPC PBS variant according to the invention (designated in the table with S 2 PC 3092 MIFT13) surprisingly significantly softer (lower) Young's modulus and lower tensile strength while having higher impact strength than SPC PLA.
- an SPC PLA material has a heat resistance of only about 55 ° Celsius and thus for the application in a coffee capsule is suitable only limited (the hot water is regularly pressed at a temperature of about 90 ° ⁇ 3 ° C from the coffee machine through the coffee capsule), while the SPC-PBS material according to the invention has a heat resistance of more than 90 ° Celsius and thus much better suited and the coffee capsule remains stable during coffee production.
- FIGS. 7 and 8 a corresponding (coffee) cup (FIG. 7) with a cup container (FIG. 8) is shown.
- the height of the cup can be between 100 and 250 mm, a diameter of 90 mm is easily possible and also a volume of 300 cc or more can be easily achieved and in a test it was found that the cup despite filling with This mug is also reusable, can be cleaned very well after use (is also dishwasher safe) and is especially in contrast to previous plastic cups "home-compostable”.
- the excellent biodegradable, home-compostable properties of the invention S 2 PC-PBS -Materials also allow this material for urns (Funeral urns) use. It is then made of the compound material corresponding manufacturing process, for example, deep drawing, embossing, injection molding, etc. manufactured the urn, in which then the ash can be filled.
- biomaterial product according to the invention of SPC PBS consisting of sunflower husk material on the one hand and PBS material compounded therewith on the other hand for the production of tree spirals, mechanical plant and insect protection, etc.
- SPC PBS consisting of sunflower husk material
- PBS material compounded therewith on the other hand for the production of tree spirals, mechanical plant and insect protection, etc.
