This product features a handheld design and dual pocket layout as its core. It belongs to the category of insulated lunch bags, made of thick aluminum foil material with insulation function. It is a lunch bag, a meal bag that can accommodate lunch boxes, and an insulated bag. Through structural design and material selection, it meets the storage and insulation needs of daily meal carrying scenarios, balancing practicality and convenience.
The handheld design focuses on the carrying experience, with a top strap length of 20cm and a width of 3cm. It is made of wear-resistant webbing and soft rubber splicing, which fits the curve of the hand when held, disperses weight, reduces discomfort, and is suitable for carrying needs in commuting, travel and other scenarios. The connection between the handheld strap and the bag body is reinforced with double wires and metal rivets to enhance its load-bearing capacity, ensuring stability and durability even when filled with food, ensuring reliability during carrying.
The dual pocket layout enhances storage efficiency, with the main pocket capable of accommodating 1-2 standard lunch boxes (with a total capacity of approximately 2-3L). The internal space is well-organized, with a three-dimensional cut that fits the outline of the lunch box, reducing shaking and avoiding soup overflow. The secondary bag is located in front of the main bag, with dimensions of 15cm in height, 18cm in width, and 5cm in thickness. It can independently store small items such as tableware, fruit boxes, tissues, etc., achieving separate storage of meals and ancillary items. It is easy to access and does not require flipping through the main bag.
Thickened aluminum foil material is the key guarantee for thermal insulation performance. The inner layer is made of food grade thickened aluminum foil (thickness 0.12mm), which reflects heat transfer. Combined with the outer layer of Oxford cloth and the middle layer of pearl cotton, a three-layer insulation structure is formed. After testing, it can maintain temperature stability within 6-8 hours (keeping warm in high temperature environments and cold in low temperature environments). It can keep meals warm in winter and delay food spoilage in summer, providing continuous insulation for meals in cooking scenarios and ensuring food freshness.
As a lunch bag and meal carrying bag, it is suitable for daily meal carrying scenarios. The overall size has been optimized (22cm high, 25cm wide, 12cm thick), which can accommodate sufficient meals without being too bulky. It is suitable for placing in backpacks, desks and other spaces. The bag body adopts a lightweight design, with an empty weight of about 300g, reducing the carrying burden and adapting to the daily meal carrying needs of students, office workers and other groups.
The feature of accommodating lunch boxes is enhanced through detailed design. The opening of the main bag is closed with a zipper, which is smooth and easy to pull, and has good sealing after closure, preventing temperature loss and odor leakage, and avoiding other items from being contaminated with food odor. There are no excess wrinkles inside, which can tightly wrap the lunch box, enhance the insulation effect, and protect the lunch box from collision damage.
As a thermal insulation bag, the material selection balances durability and safety. The outer layer of Oxford cloth has high tear resistance, which can withstand friction and compression in daily use and extend its service life. The inner layer of aluminum foil has passed food grade safety testing, with no odor or harmful substance release. It is safe and reliable for direct contact with food, and meets the standards for healthy use.
The detailed craftsmanship ensures overall quality, with neat and fine stitching on the body and edge wrapping to prevent fabric wear and thread loss, enhancing product durability. The zipper is made of smooth resin material, with a color that matches the body of the bag. It closes tightly without any jamming when pulled, ensuring that the insulation effect is not affected. The bottom is made of thickened Oxford cloth splicing, attached with anti slip patches, which is not easy to slide when placed, enhancing the stability of use.
The overall design supports adjusting details according to the target market, optimizing color schemes (adding stable color schemes to adapt to office scenes, adding fresh color schemes to adapt to campus environments), adjusting pocket sizes to adapt to different lunch box specifications, increasing or decreasing insulation layer thickness to adapt to different climate regions, and meeting diverse market adaptation requirements.
