Document Type and Number:
WIPO Patent Application WO/2023/003071
Kind Code:
A1
Abstract:
A packaging container having antibacterial and antiseptic effects, according to the present invention, comprises a natural antibacterial material, wherein the natural antibacterial material is not mixed with a normal polymer resin but rather is included in an adhesive layer that can be molded at room temperature, and thus high-temperature-induced destruction of the natural antibacterial material is prevented and an antibacterial property thereof is further improved. In addition, in order for the antibacterial power of the natural antibacterial material included in the adhesive layer to be expressed, stretch blow molding is applied during molding so that pores are formed in an inner layer, and thus high antibacterial property is maintained without deterioration in mechanical properties of the container.
