の価格も高くなるという問題が生じる。[0007] Various mechanisms have been reported in various literatures on the mechanism of the effect of the melt- kneaded antibacterial and antifungal agent in plastic containers . According to these reports, it has been reported that bacteria and fungi inhibit oxygen in the basic metabolic system such as the respiratory system and electron transfer system of cells, and inhibit mass transfer in cell membranes, thereby inhibiting cell growth. In comparison between organic and inorganic drugs, organic drugs have a greater amount of bleed-out, that is, release from the container , and a faster release rate than inorganic drugs. In addition, since the drug component easily forms a film, an effect can be imparted by adding a small amount of the drug component, but this leaves a problem in sustainability. Further, there is a problem that it is difficult to perform post-processing such as surface decoration typified by printing due to the problem that the above-mentioned drug component easily forms a film. In contrast,
Inorganic drugs are hardly released and hard to form a film on the surface of the container , so the effect lasts semipermanently, but a large amount of drug is required. For this reason, the surface of the plastic container obtained by melt- kneading tends to be rough, and there is a problem in that the price of the product increases due to the large amount of the drug added.

Printability is evaluated by immersing the container in tap water at 35 ° C. for 24 hours and then using a cellophane tape to evaluate the adhesion of the ink. In addition, the evaluation of printability was performed on the first and sixth months after molding and printing. About the antibacterial and antifungal properties, about 20 ml of an agar medium is appropriately dropped on a sterile petri dish, and after solidification, about 5 ml of an agar medium containing a bacterial solution of the following test bacteria is overlaid. The sample in which the container was cut was pierced into the center of the medium, covered, and cultured in an environment of 40 ° C. and 90% RH for 48 hours, and the antibacterial activity was determined based on the growth inhibition width. For the antifungal property, about 25 ml of an agar medium was placed on a sterile Petri dish for water retention, and after solidification, the cut sample was placed so that the printed surface was on the top, and 1 ml of the spore suspension of the following test mold was used. After culturing at 30 ° C. and 80% RH for 10 days, the presence or absence of mold on the sample is observed.
The antibacterial and antifungal evaluation was performed on the first and sixth months after molding and printing.
