Biodegradable Sealing microperforated Bags, with its unique microporous structure, has an outstanding performance in ensuring air permeability.
The microporous structure of this microporous bag is carefully designed. First of all, the size of the micropores is one of the key factors. Their size is usually at the micron level, and they are precisely controlled to allow air molecules to pass freely. These tiny channels are like countless tiny channels that allow gases to be exchanged inside and outside the bag. For some items that need to breathe, such as fresh agricultural products, the appropriate size of the micropores can not only ensure the appropriate amount of oxygen entering to meet their breathing needs and prevent the production of harmful substances by anaerobic respiration, but also allow waste gases such as carbon dioxide to be discharged from the bag to maintain the relative stability of the environment inside the bag.
The distribution density of the micropores also plays an important role. In the production process of the microporous bag, the micropores are evenly distributed over the entire surface of the bag. This uniform distribution ensures that no matter where the items are in the bag, they can obtain sufficient and uniform gas exchange conditions. There will be no local hypoxia or gas accumulation, thus ensuring the consistency of air permeability.
In addition, the shape and connectivity of the micropores also contribute to air permeability. The micropores may have irregular shapes, which increase the contact area and contact time between the gas and the pore wall, and are more conducive to the adsorption and diffusion of gas molecules. Moreover, there may be a certain degree of connectivity between these micropores, forming a microscopic gas conduction network, which further promotes the flow of gas in the bag and the exchange with the external environment, so that the air permeability of the entire bag is effectively guaranteed, whether in static storage or in a dynamic environment during transportation, it can provide good air permeability conditions for the package contents.
