This insulated bag is designed for students and can be carried by hand. It’s made of thickened aluminum foil, offering both cold and heat insulation. It can also store bento and is a Japanese-style lunch bag. Through its material selection and structural design, it meets the needs of daily food transport and is suitable for campus, commuting, and other activities.

Portability is a key feature throughout. The dimensions are optimized: 18cm high, 25cm wide, and 10cm thick. It’s compact and fits easily into a backpack or handbag without taking up too much space. The handle is 15cm long and 2cm wide, made of durable webbing and soft rubber. It conforms to the curves of the hand without any pinching. Even when fully loaded, it remains lightweight and easy to carry, making it ideal for students carrying between classes or on the commute.

The dual functions of heat preservation and cold insulation are achieved through thickened aluminum foil. The inner layer uses food-grade aluminum foil to reflect heat transfer, and the outer layer is combined with an oxford cloth and a middle layer of pearl cotton to form a three-layer insulation structure. According to tests, it can maintain a stable temperature for 6-8 hours (keeping food warm in high temperatures and cold in low temperatures). It can keep bento boxes cool and prevent spoilage in summer and keep food warm in winter, meeting the needs of different seasons and protecting food freshness.

It is particularly suitable for students. The capacity is designed to accommodate common lunch box sizes, accommodating 1-2 standard student lunch boxes. The interior is neatly arranged and wrinkle-free, tightly wrapping the lunch box and reducing movement. As a lunch box bag, the opening zips up smoothly and easily, making it easy for students to open and close. Once closed, it is tightly sealed to prevent temperature loss and odors from escaping other items in the backpack.

The Japanese style of lunch bags is reflected in their design details. The overall shape is simple and elegant, with rounded lines. The color scheme is primarily refreshing, featuring off-white, light pink, and pale blue. Some styles are printed with Japanese elements such as cherry blossoms and cartoon tableware. The small, delicate and unobtrusive patterns embody the natural and elegant aesthetic of Japanese aesthetics. They blend in perfectly with the campus environment and appeal to young people’s preference for minimalist style.

The storage function enhances practicality. In addition to storing lunch boxes, the interior features a mesh pocket for small items such as cutlery, tissues, and wet wipes to prevent loose items from getting lost. Some styles also feature a zippered pocket on the outside for meal cards and coins, allowing for centralized storage of meals and related items for enhanced portability.

The materials are chosen for both safety and durability. The outer layer is made of waterproof Oxford cloth, which resists even minor spills and protects the inner aluminum foil from moisture. The inner aluminum foil has been tested for food contact and is odorless and releases no harmful substances, making it safe for direct contact with food. The edges are hemmed to prevent the aluminum foil from fraying and thread shedding, extending its lifespan and surviving frequent daily use and cleaning.

Detailed craftsmanship ensures performance. The zipper is made of food-grade resin, which does not react chemically with the aluminum foil and ensures smooth, no-stuck zipping. The handle and body are double-reinforced, offering a load capacity of 3kg and can accommodate a fully filled lunch box without deformation. A thickened anti-slip patch on the bottom prevents slipping and enhances stability when placed.

The overall design allows for detailed adjustments based on target markets, such as adding or removing color options, optimizing dimensions to accommodate different lunch box sizes, and adjusting pattern elements to suit regional aesthetics. This adapts to the usage habits and style preferences of students in different regions, meeting diverse market needs.
