Loose produce is often more expensive than packaged fruits and vegetables because it requires more labor and resources to handle and display. Loose produce needs to be individually weighed, labeled, and arranged on shelves or in bins, which adds to the overall cost.

On the other hand, packaged fruits and vegetables are often pre-weighed, labeled, and can be easily stacked or displayed, reducing labor and handling costs. **
