One of the core functions of aluminum foil fabric is its excellent insulation and heat retention ability, which is due to the high reflectivity of aluminum foil to thermal radiation. The aluminum foil layer can reflect more than 90% of infrared thermal radiation, effectively blocking the transfer and loss of heat. Whether it is insulation protection in high-temperature environments or insulation requirements in low-temperature scenarios, it can play a key role. In the industrial field, aluminum foil cloth is often used for insulation wrapping of pipelines and equipment, such as petrochemical pipelines, central air conditioning ventilation pipelines, etc. By wrapping aluminum foil cloth on the outer layer of the pipeline, the loss of heat during transportation can be reduced, energy consumption can be lowered, and the impact of high or low temperature on the surrounding environment of the pipeline can be avoided. In daily life, the inner layer of takeaway insulated bags and car insulated boxes is often made of aluminum foil fabric, which extends the insulation time of food with its insulation performance, allowing people to enjoy warm meals at any time. In addition, in the field of architecture, aluminum foil can also be used as a thermal insulation layer for roofs and walls, blocking external heat from entering the interior in summer and reducing indoor heat leakage in winter, helping buildings achieve energy conservation and consumption reduction, and improving living comfort.
