This glass wool block is high-quality thermal insulation material designed specifically for packing boxes, which can effectively enhance the comfort and energy-saving effects of packing boxes, creating a stable environment inside the box. In terms of specifications, we offer a variety of sizes to fit different sizes of packing box spaces to meet customers’ needs for insulation layer thickness. The glass wool block is made from high-quality glass as the main raw material, which is melted at high temperatures and then formed into fibrous shapes through advanced processes such as centrifugation, followed by processes like cotton collection and molding. Its internal fibers are long, flexible, and three-dimensionally oriented, forming countless tiny air gaps, giving the product excellent thermal insulation performance. It can effectively block the transfer of heat, reducing the entry of external heat into the packing box in summer and preventing the loss of heat inside the box in winter, lowering energy consumption and maintaining the stability of the box’s internal temperature.
