In the circulation process of fruit from picking to selling, packaging bags play a key role in maintaining fruit quality, reducing wastage and enhancing commodity value. Choosing the right fruit packaging bag requires comprehensive consideration from multiple dimensions such as fruit characteristics, packaging functions, and material characteristics. ​

1. Choose according to fruit characteristics

According to the type of respiration: fruit can be divided into respiratory jump type and non-respiratory jump type. Fruits such as apples and bananas release a lot of ethylene during ripening, speeding up the ripening of their own and surrounding fruits. Therefore, such fruits are suitable for packaging bags that can adjust the gas composition, such as plastic film bags with micropores, which can moderately discharge ethylene and delay fruit ripening. And strawberries, grapes and other non-respiratory jump fruits are relatively insensitive to ethylene, pay more attention to the moisture of the packaging bag, can choose a certain breathable plastic box lined with absorbent paper packaging, both to maintain humidity, but also to avoid excessive humidity caused by rot. ​

Consider the texture and shape: soft and easily bruised fruits, such as peaches and blueberries, should choose a cushioning bag, such as a plastic bag with foam mesh cover, which can reduce collision damage during transportation. Fruits with irregular shapes, such as pineapples and cantaloupes, need the right size, shapeable packaging to ensure that the fruit is properly wrapped to prevent shaking and damage during transportation and storage. ​

2. Meet the functional requirements of packaging

Fresh-keeping function: The fruit packaging bag should have good fresh-keeping function and can adjust the gas composition and humidity in the bag. By filling the right amount of nitrogen, carbon dioxide and other gases, the air conditioning bag can inhibit the respiration of the fruit and extend the fresh life. At the same time, some bags added desiccant or ethylene absorbent, can maintain the appropriate humidity in the bag, reduce the concentration of ethylene, delay the aging of fruit. ​

Labeling and information transmission: The packaging bag should clearly mark the variety, origin, picking date, shelf life and other information of the fruit, so that consumers can understand the source and quality of the fruit and make purchase decisions. In addition, packaging bags with information such as eating methods and nutritional composition can also provide consumers with more consumption guidance. ​

3.consider the material characteristics

Safety: Packaging materials in direct contact with fruit must meet food safety standards, non-toxic, tasteless, and will not chemically react with the fruit to avoid harmful substances migrating to the fruit. Common polyethylene (PE), polypropylene (PP) and other plastic materials, after strict testing, in line with food safety requirements, widely used in fruit packaging. ​

Environmental protection: With the improvement of environmental awareness, the application of degradable materials in fruit packaging has attracted more and more attention. Environmentally friendly packaging such as biodegradable plastics and paper materials can be decomposed in the natural environment, reducing pollution to the environment and meeting the requirements of sustainable development. ​

4. take into account cost effectiveness

When choosing fruit packaging bags, it is necessary to control costs under the premise of ensuring packaging quality and function. By comparing the price of different materials and specifications of packaging bags, choose cost-effective products. At the same time, considering the promotion role of packaging bags on fruit sales, high-quality packaging can enhance the commodity value of fruit, reduce losses, and maximize economic benefits. ​

The selection of fruit packaging bags is a comprehensive decision-making process, which needs to comprehensively weigh factors such as fruit characteristics, packaging functions, material characteristics and cost effectiveness to ensure the quality and value of fruits in the circulation process and promote the sustainable development of the fruit industry.
