Definitions
- the invention relates to a process for the production of coated substrates, in which a flowable, biodegradable and gas-tight first coating is applied to a cellulose-containing substrate.
- Packaging made of cellulose, in particular made of cast fiber, cardboard and paper are enjoying increasing popularity.
- Cellulose fibers are a frequently used material that is extremely easy to recycle. Recycled raw materials (wood, paper, etc.) are also ideal for the production of cellulosic packaging.
- the cellulose is processed, for example, in the fiber casting process.
- An aqueous pulp with cellulose fibers is produced from which the fibers are shaped.
- the water can be sucked off by a suction mold, the cellulose fibers being deposited on the pore-provided surface of the suction mold.
- the transfer process the molded body formed by the suction mold is transferred to a transfer mold so that it is shaped from both sides. Additional thermal processing methods and pressing methods can be used, which increase the surface quality of the molded body.
- the cellulose can be processed into paper or cardboard and used as packaging.
- the substrates can, for. B. with cellulose fibers, in particular microfibrils and / or nanofibrils made of cellulose, are coated.
- Such coating processes are known from the publications EP 3 444 399 A1, JP 2015 227517 A, JP 2012 01 1651 A, WO 2017/144009A1, EP2529942B1 and WO 2017/072124 A1.
- the substrates coated with cellulose fibrils are additionally coated with polymers such as polyethylene or polypropylene, but also with biodegradable polymers such as polylactic acid or polyvinyl alcohol.
- the object of the invention is to produce a largely gas- and watertight packaging for packaging food, which is primarily made of natural raw materials.
- this object is achieved in that a second waterproof coating composed of predominantly animal and / or vegetable waxes and / or lipids is applied to the first coating.
- the second coating can contain, for example, at least 90% by weight of animal and / or vegetable waxes and / or lipids.
- the second coating can contain at least 70% by weight of animal and / or vegetable waxes.
- the first coating and / or the second coating can be applied by spraying.
- Sealing layer can be made resistant to water and moisture by applying a layer of natural waxes and / or oils or fats.
- Natural waxes and / or lipids mainly consist of esters of fatty acids and, as oil-soluble products, are readily biodegradable according to the test method CEC-L-33-A-93.
- the entire coated packaging thus consists mainly of
- Cellulose fibers possibly other natural components and natural ones Lipids or waxes can therefore be disposed of in an environmentally friendly way, but can also be recycled.
- the second coating can contain at least one of the following components:
- Linseed oil is used to improve the malleability of the oil-wax mixture, which forms the second coating, and to minimize brittleness after drying. Pharmaceutical, i.e. completely clarified, pure linseed oil should be used. Linseed oil is one of the few hardening oils and has been used for wood impregnation for centuries. A layer of linseed oil alone is open-pored, which means that some of the water and air can pass through, and is not suitable for permanently sealed food packaging.
- Carnauba wax is a very hard, tropical wax with a high melting temperature (approx. 85-89 ° C). It hardly smells or tastes of its own and is waterproof. It is very brittle when dry and hardens within seconds. Due to its hardness, it is also very resistant to abrasion. It is approved for the packaging of food and has long been used as a coating to increase the shelf life of e.g. Mangoes, sweets etc. are used.
- Beeswax is a wax produced in Europe, among others, which is less hard than carnauba wax. In a mixture with carnauba wax, beeswax helps reduce fragility. It has hardly any inherent odor or taste and is also approved for use in connection with food. Its melting point is around 65 ° C.
- the second coating can contain the following components:
- This mixture has the positive properties of the three components, i.e. a high level of impermeability and abrasion resistance, a neutral smell or taste, and high flexibility at ambient temperature.
- the coating properties of this mixture in combination with the underlying layer of cellulose microfibrils or cellulose nanofibrils is very well suited to meet the requirements for water resistance and gas tightness that are necessary for food packaging.
- the flowable first coating solution for the production of the first coating can have cellulose nanofibrils or microfibrils dissolved in water.
- Nanocellulose has cellulose microfibrils with a median diameter in a range from 30 to 100 nm and / or cellulose nanofibrils with a median diameter in a range from 5 to 20 nm.
- Cellulose fibrils are often a mixture of microfibrils and nanofibrils. In practice, a mixture of 2% by weight of nanocellulose in 98% by weight of water has proven itself for the first coating. If a higher cellulose content is selected, deformation of the fiber-containing substrate due to moisture can be reduced or avoided and the drying time shortened. In practice, a cellulose content of 2 to 10% by weight of the first coating solution is suitable.
- casein powder can be mixed with water and with calcium hydro- xid be denatured.
- the casein increases the tightness and mechanical strength of the substrate.
- Casein denatured with calcium hydroxide also becomes water repellent to some extent. It is also possible to denature the casein with baking soda, but this does not make it water-repellent.
- a coating with casein is particularly suitable for dairy products, the manufacture of which may produce casein. The strengthening effect of the casein coating enables the use of the
- Substrate for example, as a substitute for plastic, for example in the manufacture of disposable cutlery.
- Disposable cutlery can also be made from cellulose-coated substrates with a waterproof second layer.
- a casein coating can significantly increase the strength, B. is important when using the substrate to form a knife.
- casein powder were left to swell with 100 ml of water for about 8 to 10 hours, 30 g of calcium hydroxide were added and stirred. After another 50 ml of water had been added, the solution was sieved and used for coating.
- This coating can be applied after coating with cellulose fibers or as an alternative to coating with cellulose fibers.
- the first coating can also contain both cellulose fibers and casein.
- Whey is also suitable as a component of the first coating. Whey can be denatured by heat (90 ° -100 ° C). Whey as part of the first coating also increases the strength of the coated substrate. The whey coating itself is not water-repellent and must therefore be made waterproof with the second coating.
- gel-forming components such as agar agar (gelatine from algae) or psyllium husks (seed husks of the plantain species Plantago indica, Plantago afra) are suitable for the first coating.
- Agar agar powder is z. B. for this purpose mixed with water and for 1 min. denatured at 100 ° C. When it cools, it hardens and gels.
- the Gel can be applied to the substrate and forms a thin layer that closes the pores of the substrate, increases its strength and repels water.
- the components of the first coating can be dissolved in water and applied at the same time.
- the first coating can first be dried before the second coating of natural waxes and lipids is applied.
- the water-containing first coating does not mix with the second coating of oil and wax, so that complete drying is desirable before the second coating is applied.
- the substrate itself is formed from cellulose fibers.
- the substrate can be processed as a thin-walled product in fiber casting with or without subsequent pressing or thermal
- the substrate can take many different forms, e.g. form
- the substrate can serve as food packaging or as disposable crockery or cutlery. Particularly when used as a disposable plug, the increased strength that can be achieved by the various constituents of the first coating is of considerable importance.
- the aim is to produce a capsule into which a powder for preparing beverages, in particular ground coffee, is filled.
- Individually packaged portion packs for coffee are enjoying increasing popularity.
- Various packaging techniques are used for this. Pure aluminum packaging offers a high level of tightness and enables the coffee packed in it to be stored for a long time. However, it also requires high energy consumption and high material costs in the manufacture of the packaging and leads to considerable amounts of waste.
- So-called coffee pods are coffee portions packed in cellulose fleece. This packaging weighs less and is more easily biodegradable than aluminum packaging. However, the pads lack tightness, so that the coffee packaged in them can be stored for less long or loses its aroma.
- a coffee portion packaging consisting of a capsule consisting of the substrate described here has a high degree of tightness, which is much higher than that of a pad made of uncoated cellulose fiber. As a result, you can keep the coffee much longer.
- the capsule can be sealed with a cover layer, which consists for example of a paper layer with the coating described above.
- This capsule consists solely of natural raw materials, namely cellulose and natural waxes and lipids, and can be easily disposed of or recycled.
- a tray that is to say a single-layer body with several depressions, can first be produced using the fiber casting process.
- This tray and the wells are first sprayed with the suspension with nanocellulose.
- This first coating has dried
- This second coating can be sprayed or the substrate with the first coating can be in this
- the tray can also be pressed after the first coating has been sprayed on, in particular by means of a heated mold. This speeds up the drying process.
- the waxes and lipids of the second coating are heated for application, e.g. to a temperature of 90 ° C in order to remain in the liquid state.
- the heated reservoir for the material of the second coating can be arranged in close proximity to a drying channel for the first coating.
- the nozzles for applying the second coating can also be heated.
- the second coating cools down in a short time (a few seconds) and hardens in the process. After that, the food packaging can be used.
- the capsules which are formed by the hollows in the tray, are then filled with the intended amount of coffee and then closed with a seal.
- the seal can consist of a paper layer, also with a first coating made of nanocellulose and a second coating made of animal and / or vegetable
- Waxes and / or lipids are provided so that they are gas-tight and water-resistant.
- Sealing takes place using a tool that is precisely matched to the shape of the tray and that seals between the troughs filled with coffee on the cast fiber webs of the tray.
- the tool points Approx. 5 mm wide metal bars, which can be placed on the bars between the wells of the tray.
- the tool can be heated and pressed onto the tray with pressure, if necessary in a counter-mold.
- the counter-shape made it possible to apply the required pressure to the bars of the tray and hold the tray precisely in place in order to be able to perform the sealing.
- the tray After sealing, the tray can be cut into individual capsules. But it is also possible to cut larger sections with several capsules, which can then be separated either with scissors or by cutting on a perforation line that runs in a sealed web between two wells of the tray.
- the coated substrate is also suitable for the packaging of other objects, in particular foodstuffs which have to be packaged in a largely gas-tight manner in order to preserve freshness.
- dried foods such as seasoning mixes or powders for making soups can be packaged in a beaker with such a coating.
- Substrates coated in this way can also be used as dinner plates or drinking cups, where they come into brief contact with water.
