This lunch box bag features a forest style visual core, using Oxford cloth as the main material and a thick aluminum foil layer. It has dual functions of insulation and refrigeration, incorporating canvas elements to suit students and office workers. As a lunch box bag, it meets the temperature control and storage needs of daily meals through material combination and design details.

The forest style is reflected in the fusion of natural elements, with color schemes such as grass green, light brown, and gray green that are close to nature. The surface of the fabric retains the delicate texture of Oxford cloth and the rough texture of canvas, forming a visually rich layering effect. Some styles are decorated with simple plant embroidery (such as leaf and berry patterns), with delicate and unobtrusive lines that enhance the natural atmosphere. They are suitable for the leisure context of campus and office scenes, showcasing a low-key yet textured style expression.

Oxford cloth, as the main fabric, has durable and protective characteristics. It is made of 420D Oxford cloth with a warp and weft density of 12 × 12 strands/cm and a tear resistance strength of 70N. It can withstand frequent friction and slight scratching, and is suitable for collision and compression in daily use. The fabric is treated with fluorocarbon compounds to form a waterproof coating. When water droplets come into contact, it exhibits a lotus leaf effect, rolling and slipping without penetration, effectively blocking the invasion of liquids such as soup and rainwater, protecting the internal food from drying, and simplifying the cleaning process. Stains can be directly wiped off with a damp cloth.

Thickened aluminum foil layer is used to construct a temperature control system. The inner layer is made of 0.1mm food grade aluminum foil, which has been anodized to achieve a reflectivity of over 85%. Combined with a 2mm thick pearl cotton insulation layer in the middle, a closed temperature control space is formed. Test data shows that at an ambient temperature of 25 ℃, the internal high temperature (above 60 ℃) can be maintained for 6 hours, and the low temperature (below 10 ℃) can be maintained for 8 hours, meeting the time span needs of students from breakfast to lunch and office workers from commuting to meals, and delaying the speed of food spoilage.

The application of canvas elements enhances the user experience. The handheld strap is made of 16 inch canvas, pre shrunk to a thickness of 1.2mm, providing a soft touch when held. The 3cm width design disperses pressure and avoids hand marks. The joint between canvas and Oxford cloth is sewn with a double chain stitch, with a needle spacing of 3mm and a seam strength of 50N, ensuring that the thread does not come off during long-term use. At the same time, the natural drape of the canvas optimizes the contour of the bag body, allowing it to maintain a firm shape even in an empty state.

The storage structure is adapted to meet the needs of multiple scenarios. The internal dimensions of the main bag are 23cm × 18cm × 10cm, which can accommodate two 500ml square lunch boxes. The inner side is equipped with a mesh insert bag (size 12cm × 8cm) for storing small items such as tableware and wet wipes. The front is equipped with a zipper pocket (size 15cm × 12cm × 3cm), which can store meal cards and keys, achieve partitioned storage, and avoid inconvenient retrieval caused by mixed items.

Tailored for students and office workers, the overall weight is controlled at 280g (empty bag state), with a folded thickness of only 3cm, making it easy to fit into the side pockets of backpacks or desk drawers, saving storage space. The zipper is made of 3 # nylon, with a tooth spacing of 1.5mm and a pulling resistance of ≤ 1.5N. It opens and closes smoothly, and the chain head automatically locks after closure to ensure the bag mouth is sealed, prevent temperature loss and odor leakage, and avoid contaminating surrounding items.

The material safety meets international standards, and the aluminum foil layer has passed SGS food contact testing, with lead and cadmium content both<0.01mg/kg, in compliance with FDA 21CFR 175.300 standard; Canvas and Oxford cloth have been tested with azo dyes, and the aromatic amine content is less than 30mg/kg, meeting the requirements of the EU REACH regulation and meeting the compliance needs of importers for material safety.
