The present invention relates to a process for minimizing the formation of undesirable byproducts in ozonated liquids comprising the steps of: providing a container comprising a polyester comprising repeat units from a dicarboxylic acid component comprising at least about 85 mole percent terephthalic acid, 2,6-naphthalenedicarboxylic acid or a mixture thereof and at least about 85 mole percent ethylene glycol; and from about-to about-weight % of at least one polyamide which displays a melting point below that of said polyester, and filling said container with an ozonated liquid.
