1. A hollow weather-strip article formed from a planar extruded article having an indeterminate length, a width of about 0.1 to 10 cm and a thickness of about 0.2 to 5 mm, the article consisting of:
(a) a natural fiber fabric; and
(b) an extruded resin layer;
wherein the fabric comprising a basis weight of about 50 to 500 g-m−2, warp fiber and a fill fiber, the fabric having a count of about 50 to 4 fibers-cm−1, each fiber having a diameter of 30 to 500 denier, the article comprising an add on amount of polymer to fabric of about 0.01 to about 1 g-cm−2, a polymer thickness of less than 2 mm, a fiber tensile modulus about 2 to 10 g-denier−1, an extensibility of less than 10% in either length or width;
wherein the article comprises a width having a first edge and a second edge, the edge width comprising about 0.1 to 3 centimeters, wherein the hollow article comprises a closed volume surrounded by the flexible article joined at a joint comprising the first edge in contact with the second edge wherein the enclosed volume has a cross-sectional area of about 0.1 to about 7 cm2 and the weather strip article has a shrinkage less than 0.4%.
