ENVIRONMENTALLY FRIENDLY DISPOSABLE CONTAINER COMPRISING SEAWEED POWDER AND METHOD OF MANUFACTURING THE SAME}

1 to 3 schematically show a cross section of a disposable container including a main body and an inner portion including seaweed powder.

4 to 6 are diagrams schematically showing a cross section of a disposable container including a main body, an inner portion and an outer portion containing seaweed powder, respectively.

The present invention relates to an environment-friendly disposable container containing a seaweed powder and a manufacturing method thereof, and more particularly, to a disposable container and a method for producing the disposable container that is more economical, environmentally friendly and efficient production.

In addition to the development of the overall industrial economy, various types of disposable containers are being produced and used to save time as the human life culture is complicated and diversified. Examples of such disposable containers include lunch boxes, dishes, cups, packaging containers for electronic products, and the like.

Such disposable containers are mostly manufactured using synthetic resins such as polystyrene or pulp. However, the product using the synthetic resin or the like not only contains a large amount of harmful components to the human body, there is also a problem that the disposal of waste due to the increase in the amount of use is not easy, there is a situation that a certain restriction on its use.

In addition, since the paper products using the pulp and the like are mostly manufactured using imported pulp, high cost is required from an economical point of view, and inevitably destroys the forest which is the raw material to produce pulp, and also produces them. Environmental pollution may occur due to additives added to the process. Furthermore, even if the recycled pulp is used instead of the pulp, the secondary environmental pollution problem caused by the disposal of the product after the use of the energy required for the regeneration, additives used in various regeneration processes, and the like cannot be overlooked.

On the other hand, in order to solve the structural problems of the pulp material, containers whose surfaces are waterproof coated with vinyl are also used, but this also has restrictions on their use as a main culprit of environmental pollution. After use, the container must be collected separately.

As such, when most of the conventional disposable containers are simply buried in the ground, soil is not decomposed naturally and is decomposed naturally to solve the problem of releasing environmental pollutants such as dioxins during incineration. Disposable containers and the like are produced. However, this also has a problem that the production cost is expensive due to the use of imported pulp, there is a structural problem that the shape is changed due to partial dissolution in water when in contact with water, presently such a container Polyethylene or the like is coated on the surface or the outer surface is used to spray coating. However, the polyethylene is not only an environmentally friendly material, but also may cause contamination in the spray coating process, be treated as waste after its use, and have a practical mass production problem because it is produced through a complicated process.
