Stacks of lumber are covered with a wrapping material comprising a woven oriented polyolefin tape structure coated with a polyolefin containing an aluminum, brass or bronze metallic filler. The metallic filler is present in an amount sufficient to provide a light transmittance through the wrapping material of less than about 30% in the 450 to 700 nm range e.g. in amounts of 0.75 to 4.5% metallic filler when the thickness of the coating is between about 15 and 50 .mu.m.
