Abstract:
     This invention provides a raw material composition for manufacturing plastic products. It is prepared by mixing in proportion the materials such as polypropylene, calcium carbonate, pottery clay, talcum powder and titanate coupling agent. The amount of inorganic filler mixed into the base of polypropylene is increased because the function of the coupling agent, so the softening temp. of the woven bag is increased and the purpose of packing the material with the temp. up to 150 deg.C can be reached. The technology for preparing the composition is simple without adding any apparatus,so that having certain social and economical benefits.
