AI Technical Summary
Traditional foam boxes have poor insulation performance during long-distance transportation or in high-temperature environments, insufficient structural strength, poor sealing performance, and cannot effectively protect temperature-sensitive products.
It adopts a multi-layer structure design, including an outer high-density foam layer, a heat insulation film, and an inner heat insulation cotton layer, combined with a vacuum insulation layer and a silicone sealing structure to enhance structural strength and prevent air exchange, and uses a wear-resistant film to protect the outer surface.
It achieves long-term temperature stability, improves thermal insulation performance, enhances structural strength, reduces wear, and meets the transportation and storage needs in different environments.
