Packaging must remain in good condition in various situations, including not only the sale and distribution of fruits, but also the handling and storage of fruits.
Some fruits, especially vegetables, need to come into contact with moisture during and after packaging, and the packaging used for these types must be able to withstand long-term exposure to moisture. When packaging fruits with ice cooling, that is, ice is placed on the packaging or topped with ice during transportation, the packaging must be in contact with water and maintained in good condition. Many horticultural products require packaging that can withstand high relative humidity. Even when stored under moderate relative humidity conditions (usually 85% -95%), the moisture released by the fruit itself inside the packaging can create a 100% relative temperature. When fruits are taken out of transportation vehicles or storage warehouses at the destination market, air moisture often accumulates on the cold side of the packaging. Therefore, the packaging must undergo special moisture-proof treatment or reinforced corrugated board strength to prevent packaging damage.
High temperature resistant packaging exposed to sunlight and field heat is a problem that should be maximally controlled in the harvesting of all horticultural products. The packaging design in the field must also pay attention to avoiding deterioration. Light colored cardboard can reflect more radiant heat than natural cowhide colored cardboard, so with the same packaging materials, deterioration is slower. Flower boxes should have thermal insulation properties to prevent the effects of heat and cold on the flowers. There are reports that storing corrugated packaging at high temperatures can accelerate the delamination of corrugated boards, causing serious problems during use.
Suitable for storing fruits throughout the entire season of fruit storage and sales, the packaging in the warehouse should be able to withstand changes in environmental conditions. To reduce packaging problems during storage, stacking aids such as pallet racks, luggage racks, and pillars can be used.
