    Concerns in excess of packaging waste have increase industrial and scientific interests in the field of biopolymeric materials [1]. Poly(hydroxybutyrate) (PHB) is a well-known biodegradable, hydrophobic and semicrystalline polyester, that can be use in packaging applications in replacement of non degradable commodity polymers [2,3].     In this work two-layer films were prepared by hot pressing a PHB film and a cellulose paper sheet. Permeation and uniaxial tensile  properties of films containing 5, 10, 15 and 20 wt% of PHB were investigated.
