Development of the Functional Packaging Paper for Ethylene Gas Absorption Using Charcoal

The ability of ethylene absorption and the possibility of reusing the functional packaging paper made of charcoal powder and pulp were examined. White charcoal powder absorbed relatively higher concentrations of supplied ethylene than black charcoal powder. Compared with wetting agent A, the polyacrylamide was more effective in absorbing ethylene among other absorbents. The ethylene absorption ability was higher in the functional pulp paper, and it maintained for 5 days. The higher concentrations of charcoal in the paper showed the greater absorption ability of ethylene. However, there were no statistical differences between 120% and 150% of charcoal treatments. To determine the possibility of recycling the papers, the used papers were dried before examining the ethylene absorption ability. It was found that the reused papers had the similar ethylene absorption ability, compared with that of new papers.
