Abstract
A producing method for fruit and vegetable fresh packing material has steps of (1) mixing porous granules, material and water, (2) blending the porous granules, material and water until the water is removed to form a dry mixing powder, and (3) mixing the dry mixing powder with plastic matrix material and forming plastic granules. Thus, a bag or a packing material may be produced using the plastic granules by standard plastic producing methods, such that the bag or packing material with an outstanding fruit preservation ability may be produced by a very simple way.
