Description
P126569NL00 Title: Decomposable beverage container
BACKGROUND OF THE INVENTION The invention is in the field of food packaging. In particular the present invention is directed to a beverage container and a method for producing a beverage container.
Beverage containers can be made from a wide variety of materials, such as glass and plastic. Due to their advantages such as low weight and high strength, plastic beverage containers are widely used. Typically, these plastic beverage containers, such as plastic bottles, are produced from conventional plastics that are derived from non-renewable sources including crude oil and natural gas. Apart from being produced from fossil resources, these conventional plastics are also not biodegradable. The most widely used plastic used for the production of plastic beverage containers is polyethylene terephthalate (PET), which is typically derived from non-renewable sources.
Beverage containers and other food packaging products often end up as litter in unwanted places, such as in the street or in forests, rivers, oceans, etc. Because the plastics typically used for food packaging and beverage containers do not decompose rapidly, plastic litter tends to accumulate in the environment in many different forms, such as in the form of microplastics, which is unwanted.
Other beverage containers have been produced from materials that are derived from renewable sources and/or decompose more rapidly than traditional plastics such as PET. Such materials are typically referred to as bio-based plastics and biodegradable plastics, respectively. However, due to several disadvantages of these bio-based and/or biodegradable plastics, these alternative materials have not been as successful as PET.
Typically, these bio-based and/or biodegradable plastics have one or more of the following disadvantages when used as a bottle: - lack of physical strength; - too fast biodegradation, leading to short shelf-life of the bottle; - too slow biodegradation; - lack of resistance against high temperatures; - not suitable for carbonated and/or alcoholic drinks; - toxic for humans, animals, and/or plants; - leading to artificial flavors in the beverage in the bottle; - difficult to produce using existing equipment used for bottles made of conventional plastics; - expensive to produce.
An object of the present invention is to provide improved food packaging products, such as beverage containers, compared to containers made from bio-based and/or biodegradable plastics known in the art. Another object of the present invention is to address one or more of the disadvantages of food packaging made from conventional plastics.
BRIEF SUMMARY OF THE INVENTION In accordance with a first aspect of the present invention there is provided a beverage container comprising one or more bio-based and/or biodegradable polymers, wherein the biodegradability of the beverage container containing a beverage is higher compared to the biodegradability of the beverage container not containing a beverage.
According to a second aspect of the invention, there is provided a method for producing a beverage container as disclosed herein, comprising the steps of a) producing a preform for a container; b) stretching said preform into a beverage container.
According to another aspect of the invention, there is provided a method for producing a beverage container as disclosed herein, comprising the step of blown film extrusion.
The present invention provides means to provide biodegradable beverage containers that are less harmful to the environment regarding the use of fossil resources and/or the generation of waste than beverage containers that are made from conventional plastics. Additionally, the beverage containers according provide improvements over existing beverage containers made from bio-based and/or biodegradable plastics, by addressing one or more of the disadvantages related with these containers.
DETAILED DESCRIPTION OF THE INVENTION According to a first aspect of the invention there is provided a beverage container comprising one or more bio-based and/or biodegradable polymers, wherein the biodegradability of the beverage container containing a beverage is higher compared to the biodegradability of the beverage container not containing a beverage.
Surprisingly, according to the present invention, by selecting specific combinations of polymers, it was found that a beverage container could be produced that may be readily biodegradable and/or compostable after use, i.e., when the container does not contain an beverage or other aqueous solution, but does not degrade when the container contains a beverage. Therefore, the beverage container, e.g. water bottle, has an acceptable shelf-life when filled with a beverage, combined with fast biodegradability when empty.
Without wishing to be bound by theory, it is believed that certain combinations of one or more bio-based and/or biodegradable polymers are more stable when they are in contact with an aqueous solution, z.e., a beverage, than when they are not in contact with an aqueous solution.
Preferably, the one or more bio-based and/or biodegradable polymers are selected from the group consisting of polyesters, polysaccharides, polypeptides, and combinations thereof. Depending on the conditions, these types of polymers can be degraded by various micro- organisms.
In embodiments, the one or more bio-based and/or biodegradable polymers are selected from the group consisting of polylactic acid (PLA), polyethylene 2,5-furandicarboxylate (PEF), polyhydroxyalkanoates (PHAs), polybutylene succinate (PBS), polybutylene adipate terephthalate (PBAT), polycaprolactone (PCL), cellulose, cellulose esters, celluloid, starch, alginic acid, agar, pectin, carrageenan, collagen, gelatin, and combinations thereof. These polymers are known to exhibit good biodegradability.
Good results may be obtained when the beverage container described herein comprises a polysaccharide, such as agar.
In addition to the one or more bio-based and/or biodegradable polymers, the beverage container may further comprise one or more selected from the group consisting of plasticizers, fillers, release agents, and combinations thereof.
In embodiments, the beverage container as described herein comprises one or more selected from the group consisting of sorbitol, glycerol, vegetable oils, soybean oil, epoxidized vegetable oils, epoxidized soybean oil, and combinations thereof.
The beverage container as described herein may further comprise parts made of a different material than the materials described above, for instance for providing additional strength to the container. Preferably, this different material is also biodegradable and/or obtained from non-fossil resources, for such as wood, or even more preferably, bamboo. These parts can be used in certain sections of the beverage container that require additional strength, such as the bottom of the beverage container, and/or for sections of the beverage container that require improved part accuracy, such as a screw thread for a container cap. Another example where a part of e.g.
bamboo may advantageously be applied is the cap of the container itself, where additional strength and/or grip may be required to facilitate opening of the bottle. Alternatively or additionally, bamboo can be applied in the section of the container that may be in contact with the container cap, 5 and/or in the section of the container cap that may be in contact with the container, in order to provide a watertight seal. In that case, it is preferred to provide bamboo in the form of bamboo fleece.
According to a second aspect of the invention, there is provided a method for producing a beverage container as disclosed herein, comprising the steps of a) producing a preform for a container, said preform comprising one or more bio-based and/or biodegradable polymers; b) stretching said preform into a beverage container.
Preferably, producing the preform for a container comprises injection molding. Release agents may be present in the material of the preform and/or applied to the mold, in order to facilitate the release of the injection molded preform from the mold.
In embodiments, the stretch ratio is 2-20. Preferably, the stretch ratio with respect to volume of the preform is between 5 and 20, more preferably between 7 and 15, still more preferably between 10 and 15. During the step of stretching the preform, the length, diameter, and/or volume are increased in accordance with the above-mentioned ranges.
Preferably, the stretching in the method as described herein is performed using blow molding.
Advantageously, the equipment required for injection molding and/or blow molding may be the same equipment that is currently used on a large scale to produce beverage containers from conventional plastics. Depending on the polymers used for production of the beverage container, the operating conditions of the injection molding and/or blow molding equipment, such as blow pressure and temperature, may have to be optimized.
The stretching may alternatively or additionally be performed by filling the preform with a beverage, wherein the pressure exerted by said beverage on the inside of the preform is larger than the pressure exerted on the outside of the preform by the surrounding atmosphere.
During production and filling of the beverage containers, the preforms and/or beverage containers may experience significant mechanical stress. A part providing mechanical strength, such as a ring, may be provided around at least a section of the preform and/or the beverage container during production and/or filling of the preform and/or the beverage container, in order to provide additional mechanical strength. Such a part may assist in withstanding the mechanical stress experienced by the preform and/or beverage container during production and/or filling. Alternatively or additionally, this part may assist in carrying the preform and/or beverage container in the existing production and/or filling equipment currently used for beverage containers made from conventional plastics. Preferably, this part is obtained from non-fossil resources, for such as wood, or even more preferably, bamboo. The part providing mechanical strength may for instance be a bamboo ring.
According to another aspect of the invention, there is provided a method for producing a beverage container as disclosed herein, comprising the step of blown film extrusion.
EXAMPLES Example 1. A biodegradable polymer composition was made from 80 wt.%
agar and 20 wt.% glycerol, based on the total weight of the polymer composition.
To this end, 90 mL of water was added to 7 g agar and 1.75 g glycerol.
The resulting mixture was brought to a gentle boil.
Under continuous stirring, 120 g of sugar was added.
The mixture was poured into a mold.
Upon visual inspection, it was observed that the resulting material degraded faster upon exposure to air compared to exposure to water.
