<p>Sample bags having at least one multilayer wall are described. The multilayer wall may include an inner layer and a sealing layer. The sealing layer is outside of the inner layer and forms a seam around at least a portion of the sample bag. In certain embodiments, the inner layer comprises a patterned periphery. The patterned periphery extends into the seam to provide the inner layer with a mechanical stability. The inner layer may be a thin metal foil or a plastic film and the sealing layer may include a sealing surface of a thermoplastic, wherein the thermoplastic of each sealing layer may be fused to form a seal around the periphery of the sampling bag. The sample bag thereby an inner layer with a low permeable, low adsorption layer coupled with a second layer providing an effective seal results in a sample bag with improved sample gas stability.</p>
