New Zealand invents new packaging materials

recently, the advanced synthetic materials research center of the University of Auckland successfully synthesized two kinds of cheap waste plastics into a new advanced plastic

they synthesized a new polymer plastic from waste polyethylene plastic milk bottles and pet cola bottles. The test shows that the performance of this new type of plastic is significantly better than that of the two raw materials, and its hardness is greater than that of any raw material, and the effect of isolating oxygen is increased by times, which is very suitable for food packaging materials. The research center also found that after adding appropriate additives, the electromagnetic shielding function of this new plastic is greatly enhanced, and it is an ideal packaging material for electronic products. More importantly, this new material can be recycled for several times without degradation of performance. At present, the production machine of this new type of plastic has also been designed and manufactured by the center, with a daily production capacity of several hundred meters

the main reason for the successful synthesis of this new type of plastic is that the two raw materials have different melting points with a difference of at least 40 degrees. When milk bottles and Coke bottles melt together, pet with a high melting point forms tiny fibers with a diameter of microns or even nanometers. These small fibers control the electromechanical start-up and evenly distribute in the new materials, greatly improving the strength and hardness

at present, this new material is being patented, and the weight of the aircraft will be accurate to grams in the preparatory stage of commercialization
