Layered polymer materials include a first layer including a first cyclic olefin polymer or a first cyclic olefin copolymer, a third layer including a second cyclic olefin polymer or a second cyclic olefin copolymer, and a second layer including an amphiphilic polymer having a hydrophilic component with a Hansen Solubility Parameter distance of 8 MPa.sup.1/2 or greater from oxygen gas, while at the same time having a hydrophobic component with a Hansen Solubility Parameter distance of 8 MPa.sup.1/2 or less from COC or COP. The second layer can be in contact with and be between the first layer and the third layer. The layered polymer material can be used to construct the body of a vial or a syringe. Methods of making the layered polymer material and kits containing the layered polymer material or containers having a body constructed from the layered polymer material are also described.
