ENVIRONMENTALLY FRIENDLY PACKING MATERIAL WITH EXCELLENT PRODUCT MOLDABILITY AND FOOD STORAGE INCLUDING A SILICON DIOXIDE, POLYMER RESIN, ZINC, AND WAX

摘要

PURPOSE: An environmentally friendly packing material is provided to have moderate tensile strength and elongation, good processability, and excellent product moldability and to have excellent food storage.;CONSTITUTION: A packing material comprises 15-40wt% of SiO2; 40-80wt% of a polymer resin; 1-50wt% of zinc and 3-15wt% of wax. The polymer resin is polyethylene resin. The packing material additionally includes an organic oxide selected from titanium oxide, ferric oxide, tin oxide, silicon oxide, barium sulphate, magnesium oxide, and calcium carbonate. The packing material additionally includes one or more additives selected from dispersant, plasticizer, and pH controller. The tensile strength of the packing material is 280-350MPa.;COPYRIGHT KIPO 2013
