摘要： The invention provides a vessel for biological materials comprising a multilayer polymeric barrier material that has very low permeability to small molecules, such as water and oxygen, high flexibility and softness, and is resistant to tearing. The invention is particularly useful for forming vessels that receive biological fluids, such as ostomy bags and bags for storing blood, blood products, and IV solutions. The vessel comprises a flexible, multilayer, polymeric barrier material comprising (1) a first sandwich polymer layer, (2) at least one sandwiched, oriented liquid crystal polymer layer, and (3) a second sandwich polymer layer, the first and second sandwich layers disposed to sandwich the liquid crystal layer therebetween.
