Importance of container bag's breathability for storage and transportation of specific goods
Publish Time: 2024-12-04
In the field of storage and transportation of goods, the breathability of container bags is of great importance for specific goods.
For some goods that are susceptible to moisture or require respiration, such as grains and beans in agricultural products, the good breathability of container bags can effectively regulate the humidity and gas composition in the bag. During storage, grains will undergo weak respiration, releasing carbon dioxide and absorbing oxygen. If the container bag is not breathable, the carbon dioxide concentration in the bag will gradually increase, and the oxygen content will decrease, which may cause the grain to deteriorate and mold. The breathable container bag allows fresh air to enter slowly, discharges excess carbon dioxide, maintains the balance of gas in the bag, ensures that the grain is stored in a suitable environment, prolongs its shelf life and maintains its quality.
In the transportation link, breathability is also critical. For example, fresh fruits will emit moisture and ethylene gas during transportation. Ethylene is a plant hormone, and excessive concentration will accelerate the ripening and decay of fruits. A breathable container bag can emit ethylene and excess water vapor in time, preventing the fruit from ripening and rotting too quickly during transportation, and ensuring that the fruit arrives at the destination in a good state. For some active biological products or chemical raw materials, appropriate air permeability can prevent the adverse effects caused by pressure changes or gas accumulation in the bag, and ensure the activity and stability of the goods.
From the overall performance of the packaging, air permeability and moisture-proof and insect-proof functions work together. Moderate air permeability will not destroy the moisture-proofness of the container bag, but can prevent excessive condensation of moisture in the bag to a certain extent. At the same time, if the design of the air holes is reasonable, it can also prevent pests from breeding in large numbers in the bag, because the circulation of air is not conducive to the creation of a suitable living environment for pests.
In addition, the air permeability of the container bag is also related to the safety of the goods. During long-distance transportation or long-term storage, if the gas in the bag cannot be exchanged normally, the pressure in the bag may increase abnormally due to temperature changes or the characteristics of the goods themselves. Container bags with good air permeability can effectively avoid safety accidents such as bag rupture caused by excessive pressure, ensuring safe, stable and efficient transportation and storage of goods.
