How should fresh vegetables be packaged?

The packaging material is mainly plastic film. The implementation of commodity packaging can prevent water evaporation, keep vegetables fresh and beautiful, improve the quality of goods and make them easy for consumers to carry. The packaging of general vegetable commodities should follow the following points: first, the quality of vegetables is good and the weight is accurate; The second is to let customers see the freshness or tenderness of vegetables in the package as much as possible; Third, avoid confusing the color of vegetables with color packaging; The fourth is to explain the nutritional value and eating methods of some precious vegetables. Plastic film packaging generally has poor air permeability, so it is necessary to make some small holes to exchange internal and external gases and reduce vegetable rot.

2. Transport packaging

At present, there are many kinds of transportation packages in China, mainly including crates, bamboo baskets, plastic boxes, cartons, sacks, straw bags and nylon net bags. Crate is a good way to transport fruits and vegetables, but it is expensive and difficult to recycle. Bamboo baskets are mostly used for transportation and packaging of leafy vegetables, cauliflower, kidney beans and garlic bolts, which is more suitable in the absence of refrigerated trucks at present. Bamboo baskets of different shapes and sizes should be selected according to different kinds of vegetables, and the baskets should be lined with one or two layers of clean paper scraps or kraft paper to avoid damage. Carton is a common packaging container in developed countries, which is suitable for packaging and transportation of various vegetables, but not suitable for carton packaging without precooling and heat preservation vehicles. Carton packaging should avoid rain, soaking and frosting, and it is best to choose corrugated boxes with good moisture-proof performance. Sacks and nylon bags are generally suitable for root vegetables that are not afraid of extrusion, or some small and light vegetables, such as potatoes, garlic, onions, radishes and so on. Plastic boxes are ideal packaging for short-distance automobile transportation, and are suitable for almost all kinds of vegetables. High strength, extrusion resistance, not easy to damage, and can well protect the quality of vegetable products.
