Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry-type garbage disposal bag for a dry-type garbage processing machine which can be loaded into a dry-type garbage processing machine while being stored, and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, raw garbage such as vegetable scraps and leftovers discharged from the kitchen is treated by a composting machine or a raw garbage processor to effectively use it as a fertilizer for a home garden and Attempts have been made to reduce the amount of waste, but various problems have occurred in the compost and kitchen waste treatment machines actually used. For example, compost naturally requires a long period of time to be fermented and processed, and during that time, odors are generated, and flies and the like collect, so there is a problem in hygiene management in the use of dense residential areas. is there.

On the other hand, generally, in the garbage disposal,
Approximately 80 weight at the beginning of the input, mainly by stirring the raw garbage while heating it and promoting the decomposition by microorganisms by a microbial decomposition type garbage treatment machine and stirring the raw garbage while blowing hot air of about 130 ° C. It is known that there are two types: a dry type garbage disposal that dries raw garbage that had a water content of 10% and finally reduces the water content to about 10% by weight. .

The former microbial decomposition type garbage disposal machine requires a long time for fermenting the garbage by microorganisms to decompose everything, resulting in a large garbage disposal machine, There is a problem that maintenance of the garbage disposal is difficult to keep the microorganisms alive. On the other hand, in the latter dry type garbage treatment machine, since hot air at a high temperature of about 130 ° C. is blown, all the microorganisms decomposing the biodegradable resin are killed, so that the biodegradation does not proceed. However, since it has an advantage that the volume can be reduced to about 1/5 by evaporating and drying water, it is being widely used for household garbage disposal. The garbage thus reduced in volume is composted by being put in a separate container and fermented by microorganisms to be used as a fertilizer for home gardens.

[0005]

However, if the raw garbage storage bag is loaded into the dry type garbage disposal machine while the raw garbage is still stored, the ordinary garbage storage bag is dried during the operation of the raw garbage disposal. Since it does not cause biodegradation just by being crushed, it may be entangled with a stirring blade to stop stirring, and it will remain as a garbage storage bag even after drying, so it will remain in the dry garbage disposal machine. Manufacturers are required to put only garbage into the garbage bag without disposing it in the garbage processor. However, since this raw garbage storage bag contains wet raw garbage, even if you try to put only raw garbage into the raw garbage processing machine, the raw garbage will not stick to the raw garbage storage bag and will not come off easily. Consumers have proposed that raw garbage should be improved so that it can be thrown into the garbage processor while being kept in the garbage storage bag. Therefore, a garbage bag made of only biodegradable resin having hydrolyzability such as polylactic acid resin is a normal dry type although the degree of hydrolysis of the biodegradable resin progresses at the time of treating garbage. Since it cannot be decomposed in a short time of about 2.5 hours, which is the processing time of the garbage processor, the garbage bag made of the biodegradable resin is entangled with the stirring blade and stops stirring. Therefore, if a low-molecular-weight polylactic acid resin having a molecular weight of about 60,000 is used from the beginning when the biodegradable resin having hydrolyzability such as polylactic acid resin is used, it will be disintegrated within a predetermined treatment time. It can be subdivided to the extent that it does not get entangled with the stirring blade, but such a low-molecular-weight polylactic acid resin does not have sufficient practical strength as a garbage bag, so it can be used as a garbage bag. Can not do it.

[0006]

The inventors of the present invention have made extensive studies in view of the above problems, and as a result, the decomposition mechanism of the polylactic acid film used as the biodegradable resin is firstly hydrolyzed. It has been found that it is difficult to decompose and difficult to handle as compared with the normal microbial decomposition mechanism because it has a specific property that the decomposition by microorganisms is not promoted unless it is allowed to proceed to a certain small molecular weight. did. Therefore, a laminate sheet using a base material layer having a high disentangling property or solubility in water as a base material layer of a garbage storage bag and a hydrolyzable polylactic acid resin as a biodegradable resin layer When used, it is possible to maintain an appropriate strength when storing food waste, but when it is put into a dry-type food waste treatment machine, hot air of about 130 degrees is blown so that the water content of the polylactic acid resin in the presence of water is increased. Degradation is remarkably promoted, the molecular weight of the polylactic acid resin is promoted, the strength of the polylactic acid resin in the garbage bag is remarkably lowered, and the water resistance is also lowered, whereby the looseness or the solubility is improved. Since the high base material layer is unraveled and dissolved by water, and the strength of the base material layer is also reduced, the garbage bag is ruptured by the stirring blade that is agitated with a strong force, and the garbage bag is destroyed. Which has led to the completion of the present invention by obtaining the knowledge that it.

That is, the raw garbage storage bag for a dry type garbage disposal of the present invention is a raw garbage storage bag made of a bag-shaped body having a large number of pores formed therein. It is characterized in that it is formed by adhering a laminate sheet in which a biodegradable resin layer having hydrolyzability is laminated on at least one surface of a disentangling paper layer. Another aspect of the present invention is a method for producing a food waste storage bag for a dry-type food waste disposer, which comprises a biodegradable resin layer having hydrolyzability on at least one surface of a paper layer that is easily disentangled with water. After stacking and drying, it is processed into a bag shape and a large number of pores are perforated. Furthermore, another method of the present invention is a method for producing a food waste storage bag for a dry-type food waste treatment machine. It is characterized in that it is immersed in a liquid containing a biodegradable resin, a biodegradable resin layer is laminated, dried and then processed into a bag shape.

EFFECTS OF THE INVENTION The raw garbage storing bag for the dry type garbage treating machine according to the present invention uses paper which is easily loosened against water as a base material layer of the raw garbage storing bag and is biodegradable. Since water resistance is imparted by using a laminate sheet using a hydrolyzable polylactic acid resin or modified starch as the resin layer, it is possible to maintain an appropriate strength when storing raw garbage, but a dry type When put into the garbage processing machine, the heated garbage bag is blown with hot air of about 130 degrees in the dry type garbage processing machine to accelerate the hydrolysis of the polylactic acid resin or modified starch and The molecular weight of the lactic acid resin or modified starch is reduced, and the strength of the polylactic acid resin or modified starch in the garbage bag is remarkably reduced. As a result, the highly loose paper becomes easy to be unraveled or dissolved by water, and the strength of the paper is also lowered, and the garbage bag can be broken or collapsed by the stirring blades that are stirred with a strong force. Therefore, the raw garbage storage bag for the dry type raw garbage processing machine of the present invention can be loaded together with the raw garbage stored in the bag.
