Tianjin developed nano plastic film

Tianjin National Agricultural Product Preservation Engineering Technology Research Center developed a nano-preservative film and has passed technical appraisal. As measured by China National Testing Center, the water vapor transmission rate and permeability coefficient, physical and mechanical strength and other indicators are in line with national health inspection standards. It solves the shortcomings of traditional varieties of fruit and vegetable cling film, poor air permeability, and no mildew, and it is also advantageous for long-term storage and transportation of fruits and vegetables.
