Practical Notes

Controlling the moisture content of the timber (below 18%) is critical to prevent warping, shrinkage, and fungal growth which could spoil the fruit.

Ensure that nails are properly clinched and driven flush with the surface to prevent damage to the apples and ensure structural integrity during rough handling.

Timber used should be free from large dead knots, rot, and insect attacks to maintain box strength.
