A composition including a mixture of 1 to 80% by weight of polyolefin and 20 to 99% by weight of polyvinyl alcohol; based on 100% by weight of the polyolefin, 3 to 40% by weight of high molecular compatibilizer and/or 0.1 to 5% by weight of low molecular compatibilizer and 0.01 to 0.5% by weight of initiator; based on 100% by weight of the polyvinyl alcohol, 3 to 50% by weight of plasticizer, 1 to 10% by weight of processing auxiliary agent and 0.01 to 5% by weight of antioxidant. Also, films, sheets and processed articles having barrier properties against gases and organic solvents, manufactured by melt processing the composition; and multi layer articles using the same. These films, sheets and molded articles can maximize barrier properties against gases and organic solvents due to the unique morphology of polyolefin and polyvinyl alcohol, and also show water resistance and mechanical properties of polyolefin.
