Except as otherwise provided, it is unlawful for any person to pack any fruits, nuts, or vegetables in layers in any container which has straight sides, unless there is approximately the same numerical count in each layer.

All packed fruits, nuts, or vegetables shall be so packed that they will not move in the container. Fruits or vegetables which, after having been in storage or after having been shipped, fail to meet this requirement due to unavoidable natural shrinkage which occurs after packing, do not violate this section.
