Abstract
The invention discloses a pressure-resisting-type packing material. The pressure-resisting-type packing material is prepared from, by weight, 45-65 parts of polylactic acid, 35-46 parts of polycaprolactone, 12-36 parts of mannan, 14-28 parts of calcium carbonate, 18-46 parts of polymethylacrylic acid, 22-50 parts of nylon, 23-46 parts of polyvinyl formal and 22-35 parts of silicone rubber. By means of the mode, the pressure-resisting-type packing material has the excellent physical performance, is high in pressure strength and high in plasticity, has a buffering effect, and can achieve the quite good protection effect when a product is subjected to external impact such as vibration.
