Packing and Packaging

The primary function of packaging is protection. Fresh produce is easily bruised and cut, and the compression, vibration, and impacts of stacking and transport cause much of the damage seen at market. A package sized and built for the product cushions it, limits movement, and lets units be stacked without crushing those beneath. For grain, packaging in sacks or the design of bulk handling protects against spillage, contamination, and moisture.

Packaging also carries out secondary roles: it forms convenient handling and selling units, provides ventilation to remove heat of respiration, helps hold humidity around perishables, and in some cases creates a modified atmosphere. It also carries the labelling and traceability information that supply chains and regulators require.

• Match the strength and size of the package to the product and the stacking it must withstand.
• Provide ventilation for perishables to release heat of respiration and avoid moisture build-up.
• Avoid overfilling, which crushes produce, and underfilling, which lets it move and bruise.
• Use clean packaging and, for reused containers, ensure they do not carry decay or contamination.
• Consider cost, availability, and whether packaging is returnable, recyclable, or single-use.

The best package is the one that delivers the product to its destination in sound condition at acceptable cost. That means selecting packaging appropriate to the commodity, the distance and conditions of transport, and the market, and pairing it with careful handling. Because damage is cumulative, protecting produce at every transfer point — from field to pack to transport to store — matters as much as the packaging itself.
