Porous anti-fog fruit and vegetable packaging Bag use scenario fruit and vegetable products still have life after harvest, need to maintain its normal metabolism in order to maintain its fresh quality. Vacuum Packaging bags, tea bags so the storage process is very important, in accordance with the characteristics of different fruit and vegetable tissue structure and physiological activities, control their exhalation, metabolism, reduce water loss, the Inhalation, metabolism, reduce water loss, prevent microbial attack and enzyme action, protect the integrity of fruit and vegetable tissue, in the storage and transportation of Process commonly used in the storage and transportation of low-temperature and air conditioning two kinds of ways.
The main role of porous anti-fog fruit and vegetable packaging bags is to regulate the air. Achieve the principle of fruit and vegetable Product respiration, in a humid environment, when the humidity reaches below the dew point, will condense a layer of fine water droplets on its surface, so that the surface Blurred atomization, hindering the transmission of light waves. So after the product is packaged will form water vapor in the inner wall of the bag, condensing on the inner wall of the bag and thus the formation of water beads, water droplets, fog on the inner surface of the bag.
Seriously affect the bag's light transmission, brightness, freshness The water droplets will also have an impact on the storage cycle of vegetables, fruits and mushrooms and other agricultural products, in order to meet the normal fruit and vegetable products In order to meet the normal breathing and metabolism of fruits and vegetables, we will open a small hole in the bag. In order to meet the normal breathing and metabolism of fruit and vegetable products, we will open a small hole in the bag to vent the internal gas of the bag in time to avoid the production of fog to affect the light transmission rate. Material collocation and shortage of common common materials with OPP + CPP, PET + CPP, single-layer PE, etc..
Sometimes rely on ordinary Common porous anti-fog fruit and vegetable packaging bag is not a complete solution and control the metabolic problems of fruit and vegetable products, so a certain amount of gas permeability is required PE, PP resin as the basic material, in the manufacturing process of the film added with gas adsorption porous tuff, aragonite The addition of micro-powders such as tuff, siderite and silica, which have gas adsorption properties, can improve the performance of the film in terms of anti-fog, ethylene absorption, water absorption and anti-bacterial properties. Because of this principle, PE and PP films with adsorbent PE and PP films with adsorbent substances are often processed into a variety of multifunctional fresh packaging bags, but because of the physical method, the film has a limited ability to absorb ethylene gas. However, due to the physical method, the film has a limited ability to absorb ethylene gas, so it is mostly used for the preservation of vegetables such as cauliflower, cucumber, root vegetables and fresh mushrooms. For the amount of ethylene production For vegetables and fruits with high ethylene production, ethylene adsorbent can be placed inside the bag to enhance the effect.
