Polystyrene netsA polystyrene net can protect product from damaging each other during transport. The need for this depends on the origin of the product and type of product.
Protection against light
Light can also be a problem for storage of fruit and vegetables and flowers or plants. Chicory and potatoes are vegetables that are sensitive to light storage. Under light, many plant products will produce green pigment, for instance chlorophyll, which can affect the visual quality or the taste of the product. In some cases also toxic compounds may be produced.
Examples of protection against light or dark

Reducing light levelsPackaging can help to reduce the amount of light receive by the product, think about the blue paper covering chicory tray. Some plastic foils can also filter some light wavelength, or reduce the amount of light going through the foil (think about print cover than reduce the amount of light going through the product).

Reducing light sensitivityMA packaging can also help to reduce the light sensitivity of certain product. A kilo potato bag develops a low oxygen and rich CO2 gas conditions inside bag. Potato under this storage condition are less sensitive to green discoloration.
