Abstract

The invention relates to a fruit and vegetable anti-bacterial refreshing permeable film, comprising an upper layer, a middle layer and a lower layer, the upper layer is an anti-bacterial agent layer, the middle layer is a core layer, the lower layer is a gas adsorption layer, the middle layer is covered on the lower layer, the upper layer is covered on the middle layer, and the mass percents of the anti-bacterial agent layer, the core layer and the gas adsorption layer in the mass total sum are as follows: 15-20 percent of the anti-bacterial agent layer, 60-70 percent of the core layer and 15-20 percent of the gas adsorption layer; the invention further provides a manufacturing method of the fruit and vegetable anti-bacterial refreshing permeable film; the invention provides the fruit and vegetable anti-bacterial refreshing permeable film which can enhance the refreshing effect and effectively prolong the refreshing time and the manufacturing method thereof.

Description

technical field [0001] The invention relates to a fruit and vegetable fresh-keeping film and a manufacturing method thereof. Background technique [0002] my country is the largest fruit and vegetable country in the world. Most of the fruits and vegetables produced and sold are supplied to the domestic market, and some are exported to other countries. Since our country's fruits and vegetables have been kept fresh by traditional plastic wrap, the rot loss of fruits and vegetables caused by improper packaging in the process of storage, transportation and sales of fruits and vegetables has reached more than 30%, which is a huge loss ratio. [0003] Existing ordinary plastic wraps are used to keep fruits and vegetables fresh. Since fresh fruits and vegetables are a living body, after picking or harvesting, they are still breathing and have a vigorous life. They need to consume their own nutrients and water to maintain life; Fresh-keeping treatment, ranging from 3 to 5 days (suc...
