Description of the Related Art In recent years, the era of mass consumption of disposable products has come due to rapid economic growth and lifestyle patterns that place importance on convenience, and millions of disposable paper products such as paper cups are consumed per day. Such disposable paper products used in general households and offices are required to have waterproofness against the contents in the container. Therefore, as a method for improving the heat-adhesiveness and the moldability as well as the waterproof property, conventionally, a method in which the inner and outer surfaces of the product are thermally extrusion-coated with polyethylene has been generally used.

の再生パルプ製品を得ることもできなかった。As one of the efforts to solve such environmental problems, a method of separating a discarded disposable container into a polyethylene layer and a paper layer has been used for reuse. This method is a method in which, after crushing the recovered product, a large amount of industrial water and a strong acid or a strong alkaline solvent are added and mixed and stirred until the polyethylene layer is dissociated. Has caused the result to occur. Furthermore, such a recycling method not only does not satisfy the economical profitability by recycling, but also fails to obtain a good quality recycled pulp product.

The manufacturing process of a disposable paper cup according to an embodiment of the present invention is shown in FIG. This disposable paper cup is manufactured through steps 1 to 7. After the coating solution is applied to the surface of the first stage paper in the second stage, the first stage paper undergoes a drying process to become a third stage primary product. By this coating treatment, a film for blocking the capillary phenomenon is formed on the primary product. After the fourth step of printing letters and patterns by a process called gravure printing on the heat-bonded surface of the product, the coating solution is re-coated and dried to improve workability when molding the container. A staged secondary product is obtained. This secondary product is finally processed through the punching process of the sixth stage to become the final product of the seventh stage.

かった。Example 2: Tests and Results (1) 5 in the disposable paper cup produced according to Example 1.
About 200 ml of water at 0 ° C was added and left at about 18 ° C for 10 hours. As a result, the waterproof state was extremely good. (2) Disposable paper cup 30 manufactured according to Example 1
g was put in a beaker, 500 ml of water was added, and the mixture was stirred for 3 hours. As a result, the contents in the beaker became a paste. (3) Put the seeds of soil and plants (beans, green onions, watermelons, etc.) in the disposable cup manufactured according to Example 1, and set the temperature to 20.
It was buried in soil in a glass box at 70 ° C and a humidity of 70-80%. As a result, the mold began to spread after 10 to 13 days had passed, and after 30 days, the roots of the plant had grown outside the cup.
After 40 to 50 days, the product was decomposed and the cup shape was almost lost. (4) 9 in the disposable paper cup manufactured according to Example 1.
Warm water at 0 to 95 ° C was added and the mixture was left for 3 hours. No water leakage occurred. (5) The paper cup of the present invention was examined for toxicity to animals. The paper cup prepared according to Example 1 was charged with boiling water and left for 10 minutes so that any toxic substances could be extracted to obtain an extraction solution. Then add this extraction solution to 1
It was orally administered to 0 male and female rats in an amount of 0.5 ml per 100 g of body weight. No toxic effect was observed after 1 week.
