The 1989 Supply Conference held by the State Economic Commission and the import of “triene” did not set any orders. Second, the shortage of plastic materials, increased packaging cartons, plastic packaging demand will also increase. As the wooden box packaging will be greatly reduced, the weak foundation of the plastics industry, “triene” a lack of supply, so to plastic substitution wood has been limited,
