<p>A stretchy polyolefin wrap has an inner woven scrim that is extrusion coated on one or both sides. The reinforcing polyolefin tapes of the inner woven scrim of the polyolefin wrap are made at a draw ratio of about 2:1 to about 4:1. The lower draw ratio of the stretchy polyolefin tape helps to achieve a modulus and orientation suitable for use in the automated wrapping process of lumber. The stretchy polyolefin wrap can be stretched over a stack of lumber at relatively low stress levels and maintained around the stack of lumber in the stretched state without becoming loose and without the use of staples.</p> |
