Abstract: The mathematic models for the gas control system of packaging and transportation under ideas conditionswere analyzed, based on its weakness, research focuses and practical difficulties existed in current circulation of freshagricultural produce in China. A respiration oriented mathematic model for the gas regulating system of packaging andtransportation of fresh horticultural produce was constructed, based on the characteristics of current package systemunder current merchants logistic conditions. This model could be helpful in guiding the manufacture of packagematerials and ensuring safe circulation of horticultural produce

Key words: merchants logistics, package material, osmotic coefficient, model
