    摘要: A flexible tube includes a first polymer layer and a second polymer layer adjacent to the first polymer layer. The first polymer layer includes a polyolefin, an ethylene vinyl acetate copolymer, an ethylene/norbornene copolymer, a styrenic block copolymer, a styrene butadiene copolymer, or combination thereof having a total organics content of less than about 12 μg/L per USP 34, Chapter 643. The second polymer layer includes a polyolefin, a styrenic block copolymer, a blend thereof, or combination thereof, wherein the second polymer layer has a shore A durometer of less than about 65. Further included is a method of forming the flexible tube.
