    • PURPOSE: A gas absorption resin composite for packing food and a molded product having the same are provided to absorb and remove ethylene and other harmful gases which are generated from the breaths of fruit and vegetable and causes the over-maturation of the fruit and the vegetable, to absorb and remove odor-causing gases such as amine, ammonia, and acetic acid generated from meat, and to prevent decomposition due to microorganisms with an anti-bacterial effect, thereby maintaining the freshness of fruit, vegetable, fish, and meat, extending the expiration date of food, and improving the purchasing value of a product. CONSTITUTION: A gas absorption resin composite for packing food contains 50 to 85 wt% of a substrate resin, 5 to 40 wt% of gas absorption porous powder of which the particle size is 200 to 2000 meshes, 1 to 5 wt% of a molded surface improver of which the particle size is 200 to 2000 meshes, 1 to 5 wt% of a lubricant, and 0.2 to 3 wt% of a polyolefin wax. The substrate resin is one or a mixture of at least two selected from a group of polypropylene, polyester, polyethylene, polystyrene, polylactic acid, polybutylene succinate, polyhydroxybutyrate, polyhydroxyalkanoate, and polyvinyl chloride. The gas absorption porous powder is one or a mixture of at least two selected from a group of illite, zeolite, conglomerate with seven stone, bentonite, titanium dioxide, tourmaline, germanium, barley stone, shell, red clay, kaolin, aluminum hydroxide, and activated charcoal. The molded surface improver is calcium carbonate powder, talc powder, or a mixture thereof. The lubricant is one or a mixture of at least two selected from a group of calcium stearate, zinc stearate, glycerine stearate, butyl stearate, calcium behenate, zinc behenate, glycerine behenate, butyl behenate, a solid paraffin, a fluid paraffin, a beeswax, a mold wax, an emulsifying wax, and a candellila wax. The polyolefin wax is a polyethylene wax, a polypropylene wax, or a mixture thereof.
