The Arch Handle Cool Bag by NICHIDO Co., Ltd. utilizes a unique ultrasonic laminate processing technology developed to maximize cooling effects. This technology allows for the layering of materials with different properties using ultrasonic welding, creating a bag that combines functionality and design with a handle that is both ergonomic and offers superior sealing. NICHIDO Co., Ltd., a company specializing in the use of ultrasonic technology to process and manufacture various materials, produces primarily bag-shaped products in its domestic factories. Using ultrasonic technology eliminates the need for adhesives, allowing for production in an environmentally friendly setting and making it easier to recycle excess materials.
Originally developed as packaging for New Year’s osechi cuisine gifts, the Arch Handle Cool Bag was designed to match the quality of its contents with both exterior appearance and functionality. It has since found wider application, proving ideal for cherry blossom viewing and outdoor activities. The arch handle not only enhances the bag’s sealing capabilities but also serves as an iconic symbol. To balance cooling efficiency with design, the body is trapezoidally shaped with a composition of 4 to 5 layers of material. Variations include a water-repellent film on the exterior, offering choices suited to different occasions. Without the use of adhesives, there’s no concern about odors transferring from solvents. NICHIDO also accommodates OEM, allowing for customization in color and pattern to create original Arch Handle Cool Bags.
