The present invention relates to a method for fabricating olefin tarpaulins and, more particularly to a method for fabricating olefin tarpaulins which have light weight per area and produce no poisonous gas during its incineration, formed by coating films of olefin synthetic resins to both sides of base fabrics woven from high strength polyester filaments by using an extruder and compressing the coated polyester fabrics with a calendering roller, thereby leading to a simple process that requires no special binder treatment.. The coating composition of olefin synthetic resins is prepared by dry-blending or melt-blending LLDPE (linear low density polyethylene) or LDPE (low density polyethylene) of 15 SIMILAR 94.5 % by weight with: elastomer of ethylene- alpha -olefin co-polymer of 5 SIMILAR 60 % by weight which is ( i ) ethylene propylene rubbers or ( ii ) co-polymers of ethylene and octene or butene; coloring master batch chip of 0.5 SIMILAR 15 % by weight formed by mixing LLDPE or LDPE with pigments or titanium dioxide; and adhesion-preventing master batch chip of 0 SIMILAR 10 % by weight formed by mixing LLDPE or LDPE with silica or calcium carbonate.
