Natural color food packaging

The independent construction of the original "spring forest model" for high-value and deep utilization of straw, and the innovative development of straw source fulvic acid and straw natural pulp products provide an industrialization engineering scheme for a package solution to outstanding problems in agriculture, resources and environment such as haze reduction, forest resource felling, greenhouse gas emission reduction, soil fertility improvement, quality improvement, yield increase, chemical fertilizer reduction and pesticide reduction. The "Spring Forest Model" for comprehensive utilization of straw has been included in the "Dawn of Ecological Civilization", "Typical Model of Circular Economy", and "National Typical Model of Comprehensive Utilization of Agricultural Products and Processing By-products" and other national case databases due to its outstanding comprehensive benefits and typical significance.
