Based on a square design and constructed from thickened aluminum foil, this lunch box tote is an insulated bag suitable for office workers and students carrying lunch. Its large capacity also makes it suitable for picnics. This combination of structure and function meets the needs of carrying and keeping food warm in a variety of situations.

The square design offers multiple advantages. Its clean, contoured shape fits seamlessly around common square lunch boxes, minimizing internal movement and reducing the risk of spills. The square structure allows for more efficient storage, allowing it to be stably placed in backpacks, desks, and other spaces without taking up excess space. It also enhances the bag’s three-dimensional appearance, creating a neater, more tidy appearance, perfectly meeting the needs of office workers and students for organized storage.

Thickened aluminum foil is the core of this thermal insulation performance. The inner layer utilizes food-grade, thickened aluminum foil with a thickness of 0.12mm, offering enhanced heat reflection. This is complemented by an outer layer of Oxford cloth and a middle layer of pearl cotton, creating a three-layer insulation structure. Tests have shown that this bag maintains a stable temperature for 6-8 hours, effectively retaining food heat in high temperatures and slowing spoilage in low temperatures. This ensures continuous heat preservation and freshness for lunches, student snacks, and picnics.

As a lunch box tote, the tote design emphasizes practicality. The top handle is 16cm long and 3cm wide, constructed from a combination of wear-resistant webbing and soft rubber. It conforms to the curve of the hand and reduces pinching, making it convenient for commuters and students to carry to and from school. The handle is double-stranded and reinforced with metal rivets at the connection to the bag body, enhancing its load-bearing capacity and ensuring stability even when fully loaded.

This bag is ideal for both office workers and students carrying lunch, with tailored details. The interior can accommodate two to three standard square lunch boxes (total capacity approximately 2.5-3.5L), as well as cutlery, fruit boxes, tissues, and other items, meeting all your lunch-packing needs. Its minimalist design, with a palette of primarily basic black, gray, and off-white, blends seamlessly into both office and campus environments.

The large capacity expands its use cases. As a picnic bag, it can accommodate multiple meals, folding cutlery, and small snacks, perfect for short picnics. The bag features a three-dimensional expansion design with an interior height of 22cm, a width of 20cm, and a thickness of 12cm. This strategically distributed space ensures the square structure maintains stability even with its large capacity.

The material selection is both durable and safe. The tear-resistant Oxford cloth outer layer withstands the friction and pressure of daily use, as well as minor bumps during picnics. The aluminum foil that comes into contact with food has passed food-grade testing and is odorless and releases no harmful substances, ensuring safe and reliable use. The fabric is treated with a water-repellent finish, making it impervious to minor spills and easy to clean. Stains can be restored with a damp cloth.

Detailed craftsmanship enhances the user experience. The bag’s stitching is meticulous and precise, and the edges are bound to prevent fraying and thread shedding, extending its lifespan. The zipper is made of a smooth resin material, closing tightly and smoothly, ensuring thermal insulation. A non-slip pad on the bottom prevents slippage and enhances stability when placed. The overall design allows for adjustments to specific details based on target markets, such as optimizing color palettes, adjusting internal compartments, and varying handle lengths, to suit different user habits and aesthetic preferences.
