Specifically, the material of the outer insulation layer 4 is one of aluminum-plated polyester film and microporous foam material, and a high-strength polyester fiber layer is arranged on the side of the outer insulation layer 4 facing the inner insulation layer 5. These materials can effectively reflect sunlight and thermal radiation and reduce the conduction of external heat into the bag. The high-strength polyester fiber layer is selected as the base material of the outer insulation layer 4, which has excellent wear resistance, tear resistance and weather resistance, thereby ensuring the overall strength and durability of the woven bag.

[0025] In a further embodiment, the inner insulation layer 5 has the performance of blocking heat transfer. The material of the inner insulation layer 5 is one of silica aerogel, glass fiber wool, and ceramic fiber wool, and an aluminum foil layer is embedded in the inner insulation layer 5. These materials can effectively block the transfer of external environmental heat to the inside of the woven bag body 1, forming a stable thermal insulation barrier. In addition, an aluminum foil layer is embedded in the inner insulation layer 5, which further increases the heat reflection ability of the woven bag body 1 and improves the thermal insulation effect.

[0026] In a further embodiment, the base fabric 6 is made of nylon cloth, which has waterproof properties to ensure that the items in the bag are not damaged by moisture. At the same time, the softness of the nylon cloth can protect fragile or sensitive items from wear and tear. The joints of the woven bag body 1 are sewn with nylon thread, which has high sewing strength and can ensure the firmness of the seams.

[0027] In a further embodiment, support rods 3 are provided at the two long sides of the bottom of the woven bag body 1, which can provide support for the bottom of the woven bag body 1 along the length direction. After the woven bag body 1 is loaded with items, the woven bag body 1 can maintain its original shape as much as possible, which is conducive to the stacking and transportation of the woven bag body 1 after the items are loaded.

[0028] As a preferred technical solution in this embodiment, the support rod 3 is composed of a first support rod 7 and a second support rod 8 that are symmetrical to each other. A plug-in rod 9 is provided at one end of the second support rod 8 toward the middle of the woven bag body 1, and a plug-in hole 10 is provided at one end of the first support rod 7 toward the second support rod 8, into which the plug-in rod 9 can be inserted.

The outer insulation layer 4 is made of one of aluminum-plated polyester film and microporous foam material. These materials can effectively reflect sunlight and heat radiation, reduce the conduction of external heat into the bag, and use a high-strength polyester fiber layer as the base material of the outer insulation layer 4. It has excellent wear resistance, tear resistance and weather resistance, ensuring the overall strength and durability of the woven bag; the inner insulation layer 5 is made of one of silica aerogel, glass fiber wool, and ceramic fiber wool. These materials can effectively block the transfer of external environmental heat to the inside of the woven bag body 1, forming a stable insulation barrier. In addition, an aluminum foil layer is embedded in the inner insulation layer 5, which further increases the heat reflection ability of the woven bag body 1 and improves the heat insulation effect; wherein, the base cloth 6 is made of nylon cloth, which has waterproof properties, ensuring that the items in the bag are not damaged by moisture, and at the same time, the softness of the nylon cloth can protect fragile or sensitive items from wear; wherein the joints of the woven bag body 1 are sewn with nylon thread, and the sewing strength is high, which can ensure the firmness of the joints. Therefore, the woven bag body 1 is made of a combination of multi-layer insulation materials and reflective coatings, which effectively isolates the influence of external environmental temperature changes on the items in the bag, keeps the temperature in the bag stable, and at the same time has many properties such as certain waterproof and moisture-proof, wear-resistant and durable, and strong load-bearing capacity. Furthermore, by passing support rods 3 through the two long sides of the bottom of the woven bag body 1, support can be provided to the bottom of the woven bag body 1 along the length direction. After the woven bag body 1 is loaded with items, the woven bag body 1 can maintain its original shape as much as possible, which is beneficial to the stacking and transportation of the woven bag body 1 after the items are loaded. In addition, by pulling the pull rod 13 through the pull handle 14, the plug-in rod 9 is pulled out of the socket 10, and the first support rod 7 and the second support rod 8 that constitute the support rod 3 can be separated, which is beneficial to the folding and storage of the woven bag body 1 when it is empty.
