Description

technical field

[0001] The invention belongs to the technical field of fruit fresh-keeping materials and applications, in particular to a nano-sized fresh-keeping bag material and its preparation method and application. Background technique

[0002] Fruits are easily affected by external factors such as physical, chemical, and biological factors during production, processing, transportation, and storage, resulting in a decrease in their quality. Packaging can not only avoid the adverse effects caused by the above factors, but also endow them with Food appearance aesthetics. From the perspective of the root cause of food spoilage, microbial activity is the main cause of its quality decline. Therefore, the use of fresh-keeping packaging systems to control microorganisms in food preservation is one of the important ways to prolong food storage.

[0003] Fresh-keeping bags are widely used in daily life. According to the production materials, fresh-keeping bags are divided into ...
