low-melting-point copolymer and multiform accessory ingredients by mixing,extruding,blowing molding and heat-sealing bag making.The product has good mechanical strength and flexibility,and its characteristic of low melting point can be melted with rubber,which cannot be replaced by other products.Meanwhile,it also has such function as good water resistance and corrosion protection.
