Definitions
- the invention concerns bio-containers for the collection of bio-waste and municipal waste, especially a bio-container modified into a shopping bag which after serving its primary function fulfils a secondary function as a bio-container.
- bio- containers found mainly in households. These are in the form of bags, usually of a size suitable for insertion into rubbish bins. Once full, such a bag is sealed either by tying a knot at the top or if so equipped, with a drawstring that runs in a tunnel around the open end of the bag.
- Existing containers are supplied either as loose bags, or blocked or as a perforated tube with welded bottom wound into a roll.
- Mainly bag containers with a free end that is sealed by tying a knot are produced in this way.
- Mainly bags with a drawstring are produced as loose pieces.
- biodegradable polymers from the group including polylactides, for example, modified polylactic acid (PLA), modified starch and co-polyesters.
- shopping bags with a secondary application as a container for the collection of waste, especially bio-waste and municipal waste, which are composed of a film bag made of biodegradable or oxodegradable polymer material, whereby this bag, apart from featuring handles to facilitate carrying in the upper part, also have a sealing element or elements.
- These are manufactured from common polymers - especially from polyethylene in all its variants - LDPE, HDPE, LLDPE, mLLDPE and mixtures of these, sometimes including oxodegradable additives to speed up decomposition on the rubbish dump.
- the drawback in using such bags is that municipal waste comes in all shapes and forms (e.g. formed plastic packaging, tins) and after sealing the bag, be it loose or with a drawstring, its shape and volume do not adapt to the items it contains.
- the bag is "inflated" with considerable unutilised volume. Once the bag is disrupted on the rubbish dump or during composting, mixing together of the contents occurs, which mainly on rubbish dumps may take several years and makes effective utilisation of the rubbish dump much more difficult.
- a bio-container for the collection of bio-waste and municipal waste helps to eliminate the above-mentioned shortcomings, especially when designed as a shopping bag with a secondary function as a bio-container (made as a bag made of polymer film material, which apart from featuring handles to facilitate carrying in the upper part, also has a sealing element or elements).
- the principle of the invention lies in the fact that the bio- container bag is made of polymer film material that features a set of through holes, cut-outs and/or cuts.
- the set of through holes will preferably be a set of round holes with a diameter of 0.5 to 2 mm, whereby the density of such holes is 1 to 2 per cm 2 .
- Individual round holes can have a reinforcement formed around their perimeter.
- the polymer film bag of the bio-container is provided with a set of round holes with a diameter of 2 to 20 mm, 5 to 10 mm being the best size, whereby these holes are arranged in a diamond or rectangular shape with centre spacing equal to 4 to 6 times their diameter.
- Another option is a set of cuts running horizontally across the bag or diagonally across it, whereby individual cuts are 5 to 20 mm long and are arranged in rows with horizontal spacing of 5 to 20 mm and vertical spacing of 20 to 50 mm.
- the polymer film material can also be provided with a set of cut-outs in the shape of a cross or letter Y, with individual branches of the cut-outs 5 to 10 mm long.
- the set of holes, cut-outs and/or cuts in the polymer film material can preferably be created only in the upper part of the bag, with a minimum distance from the bottom edge of the bag of 0.1 to 0.2 the height of the bag.
- the polymer material of the bio-container bag can preferably be made of biodegradable or oxodegradable polymer material.
- the biodegradable polymer film material of the bio-container bag is material that comes from the group including polylactic acid, modified starch and co-polyester.
- the oxodegradable polymer film material of the bio- container bag is material that is based on certain types of polyethylene - LDPE, LLDPE, mLLDPE or mixtures of them, featuring an oxodegradable additive or where suitable, an inorganic filler.
- the given modification can also be carried out on the whole area of the bag or just in its upper part, away from the bag's bottom. This design is advantageous in that when dumping bio-waste, a low-viscosity proportion of it is sometimes created - liquid that can escape through the holes and cuts and pollute the surroundings.
- the bio-container is in the form of a plastic carrier bag, produced as a welded plastic film bag, with dimensions of 350 mm (width) by 460 mm (height), with a bottom turnup of 50 mm.
- the circumference of the upper part of the bag features a welded tunnel 40 mm wide, in which is placed tape made of plastic or textile material and 1 mm wide.
- the bag is further provided with welded plastic handles 0.110 mm thick to facilitate carrying.
- the container's material is film of thickness 0.080 mm made from biodegradable polymer based on a derivative of polylactic acid (PLA). This film features a set of round holes 1 mm in diameter, arranged 1 cm apart from each other both horizontally and vertically.
- the bio-container is again in the form of a plastic carrier bag, produced as a welded plastic film bag with dimensions of 350 mm (width) by 460 mm (length) with a bottom fold-up of 50 mm.
- the circumference of the upper part of this bag features a welded tunnel 40 mm wide, in which is placed tape made of plastic or textile material and 15 mm wide.
- the bag is further provided with welded plastic handles 0.110 mm thick to facilitate carrying.
- the container's material is oxodegradable polymer film that contains 85 % by weight of LDPE of weight 918 kg/m 3 , 5 % by weight of the oxodegradable concentrate ADD-X from the company BIOTECH, and 10 % by weight of micronised limestone.
- This film features a set of cut-outs in the shape of crosses with a shoulder length of 5 mm.
- the lower part of the container (the bottom) does not feature any cut-outs for a distance of 0.2 times the overall length (i.e. 92 mm).
- a bio-container in the form of a plastic carrier bag is produced in the same dimensions, from the same material and in the same basic construction design featuring a tunnel and plastic handles, as examples 1 and 2.
- the film of the bio-container bag features a set of round holes 1 mm in diameter, arranged 1 cm apart from each other both horizontally and vertically.
- the edges of these holes are reinforced (note: these holes are created using technology that pierces the material with hot needles)
- a bio-container in the form of a plastic carrier bag is produced in the same dimensions, from the same material and in the same basic construction design featuring a tunnel and plastic handles, as examples 1 and 2.
- the film of the bio-container bag features a set of cuts 10 mm long that run horizontally across the bag. These cuts are arranged in rows with horizontal spacing of 20 mm and vertical spacing of 25 mm.
- a bio-container in the form of a plastic carrier bag is produced in the same dimensions, from the same material and in the same basic construction design featuring a tunnel and plastic handles, as examples 1 and 2.
- the film of the bio-container bag features a set of round holes 5 mm in diameter that are arranged in a diamond shape with a centre spacing of 25 mm.
