Absorbent paper was used as the core paper covered with the facial tissue on both sides and bonded with hot melt adhesive. 1-MCP preservative paper was prepared with quantificational 1-MCP put in the holes punched evenly in the core paper. The release regularity of the 1-MCP was studied by using the GC-MS.

The influences of 1-MCP dosage on se...
