The woven cloth has good breaking resistance and tensile strength. The composite aluminum film material is a good thermal insulation material. Products are widely used in building roofs, agricultural breeding greenhouses and industrial products of thermal insulation packaging materials. This kind of material has high strength, high impact resistance, not easy to be damaged, not easy to leak. It is generally used in packaging, bag making, etc. It can be heat sealed at high frequency, and it has certain tensile capacity, and the effect of heat preservation and insulation.
