High polymer tube having modified inner surface

Abstract

Abstract PURPOSE:A high polymer tube usable for blood bag tubes, gas piping, etc., having desired inner surface properties, wherein the inner surface layer has a discharge- treated surface. CONSTITUTION:A discharge-treated layer is formed on the inner surface of a high polymer tube. Polyethylene, regenerated cellulose, triacetate, polyvinyl chloride, polyster, polycarbonate, etc. may be cited as the polymer. The high polymer tube may be a hollow one which is seamless or made by joining a film (or sheet) and has continuous holes along the long direction. The tube has a discharge-treated surface, which is subjected to glow discharge, or has the whole surface of a graft polymer layer or a plasma polymer layer.
