Fruit packaging design

For a long time, the packaging of fruit on the market has been very simple, and the "soil" taste is too strong. With the continuous improvement of people's living standards and the constant changes in consumer psychology, the traditional trading pattern of agricultural products from the field to the market has been shown to be behind. Fruit is placed in the shelves of supermarkets is no longer a novelty. However, among the fruits placed in many supermarkets, it is very difficult to see domestically produced fruit, and almost all of them are imported. The reason is that fruit packaging cannot keep up.
Nowadays, people’s awareness of packaging has begun to increase, and packaging has also become an effective means to increase the added value of products. However, fruit packaging has not yet been given a fundamental importance. Farmers must completely change their minds and refer to packaging and planting as equally important. Not achievable overnight.
The requirements for fruit packaging protect the fruit from harm. The fruit packaging must first have a real protection function to avoid all physical injuries. Under normal circumstances, the packaging should protect the fruit from the following injuries:
Shock damage. Impact damage is mainly caused by fruit colliding with each other or with a hard object. Shock damage may not be apparent in appearance, and it is usually the main cause of injury that drops the fruit in the packing box when packing the fruit. Pads should be added to the design of the package and must be carefully handled and supervised to reduce the impact of fruit damage.
Compression damage. Compression damage is mainly caused by unsuitable packaging size. The size of the package should be appropriate to suit the packaged fruit and to avoid the compression damage caused by overpacking. Excessive packaging and overpacking of the packaging can cause fruit compression damage. Therefore, the fruit packaging must have sufficient strength and high humidity resistance.
Shock and bruises. Fruit damage due to shocks in transit is less noticeable. The damage caused by the shock is generally on the surface of the fruit, but the soft fruit may damage the deep flesh. In order to prevent shock damage, the fruit should be kept in a proper density in the package, and be fixed in the packing box.
Fruit packaging should meet special temperature requirements. The fruit packaging should protect the inside of the package from external ventilation. Only ventilation can quickly dissipate the heat inside the package. Increasing the size of the vent within a certain limit can promote heat exchange. Ventilation holes should not be blocked by internal packing or underlayment. During transportation, cold air should be able to pass through the holes. A suitable small number of large ventilation holes is better than many small ventilation holes. Corrugated carton packs with a vented area of ​​5% on the side can quickly reduce the temperature inside the box, and will not over-soften the box due to moisture. Some fruits need to be cooked before retail, need to be evenly heated and treated with ethylene, and the packaging must be suitable for warming and ventilation.
Prevent fruit moisture loss. Many fruit products shrink due to moisture loss during handling and sales. Loss of water is caused by the difference in water vapor pressure between the fruit and the surrounding dry environment. During storage of fruits, high relative humidity can be maintained to reduce moisture loss, but it is difficult to control environmental humidity during transportation and sales. Therefore, the packaging must have a moisturizing function to prevent loss of fruit moisture.
For special treatment. Fruits that require special treatment must consider the choice and design of the packaging. If the product requires fumigation, a well-ventilated package is required to facilitate the passage of fumigated air. Ventilation designs that generally allow rapid cooling are also suitable for fumigation.
Suitable for other mechanical processes. Since some processing systems still require manual handling when working, they limit the weight of the package, while some systems are designed for pallets and mechanical shipping. Therefore, the design of the packaging must be compatible with the packaging machinery handling and handling process. The dimensions should be suitable both for the overall loading and for the mixed loading.
Fruit packaging design requirements Package design should be suitable for overall processing. Package design suitable for overall processing refers to the safety, quantity, and volume requirements that are suitable for shipping trays. When selecting the package size, attention should be paid to the connection between the production area and the market place. In order to stabilize the tray loading, stacking handles and the like should be designed on the overall package.
Fruit packaging should be standardized. At present, the types, shapes, and sizes of fruit packaging are extremely inconsistent. Many packaging designs are not suitable for loading and unloading, and often cause serious damage to fruit during mixed transportation or retail distribution. Therefore, it is very necessary to establish a series of standardized packaging and be suitable for international use. On the metric system. When designing a fruit package, the size of the package should be adapted to pallet handling.
Fruit packaging should be suitable for the needs of fruit handling and environmental conditions The fruit must remain in good condition during handling, storage and sales.
Resistant to moisture. Many fruit packagings need to be exposed to moisture for a long period of time. This requires that the packaging must have good moisture resistance so that it can maintain its good condition even in a high relative humidity environment.
High temperature function. Corrugated carton packaging at high temperatures may accelerate the delamination of corrugated cardboard. In fruit harvesting, the package should be protected from exposure to sunlight as much as possible. With the same packaging material, light-colored cardboard can reflect more radiant heat than natural cowhide-colored paperboard. The deterioration is slower. Light-colored corrugated cardboard should be used as much as possible.
Suitable for fruit storage. In the process of fruit storage and sales, the packaging must withstand changes in environmental conditions. To reduce packaging problems during storage, stacking aids can be used to reinforce the packaging, such as pallet racks, luggage racks, and pillars.
Convenient for inspection, sales and post-processing of packaging. The fruit packaging should facilitate the inspection of the products that are packaged inside, and must be able to be safely reclosed, or the design of inspection openings on the packaging also has the same function.
The fruit packaging design should facilitate the display of merchandise to promote sales. The packaging used for retail display must be suitable for the needs of retail sales. The packaging and decoration design must be novel and unique, and it is easy to attract consumers' attention.
Generally used packaging materials should be treated with waste, and do not pollute the environment. Especially after the ISO14001 standard is in effect, the development of environmentally-friendly packaging has become a necessary task. Follow the trend of environmental protection, choose green packaging, and focus on the design of fruit packaging. consider.
