Fermented feed breathing bag is a widely used bagging method in modern agriculture, which can effectively maintain the freshness and nutritional value of feed. As a commonly used material for manufacturing fermentation feed breathing bags, multi-layer co extruded film has unique oxygen permeability, making it highly favored by farmers and feed manufacturers. So, how is the oxygen permeability of multi-layer co extruded films achieved? What are the advantages of its application in fermented feed breathing bags?
Multi layer co extruded film is a material made by co extrusion process of two or more thin films. Among them, the transparent outer film is usually made of polyethylene (PE), while the white inner film is composed of a special material that has a certain degree of oxygen permeability. By controlling the composition and structure of the inner membrane during the manufacturing process, an appropriate amount of oxygen permeation can be achieved to meet the respiratory conditions required for fermented feed.
The oxygen permeability of multi-layer co extruded films mainly depends on the microporous structure in the inner membrane. These micropores can be controlled through precise processes to achieve ideal oxygen permeation rates. Moderate oxygen permeation can meet the respiration needs of microorganisms during the fermentation process, thereby promoting the fermentation effect and nutritional value of feed. At the same time, multi-layer co extruded films can effectively block external pollutants and moisture, maintaining the dryness and hygiene of feed.
In the application of fermented feed breathing bags, multi-layer co extruded membranes have unique advantages. Can provide stable oxygen permeability, maintain the freshness of feed and the stability of nutritional components. Multi layer co extruded film has good plasticity and tear resistance, which can effectively prevent the rupture and damage of packaging bags. In addition, due to improvements in manufacturing processes, the cost of multi-layer co extruded films is gradually decreasing, making them an ideal choice for farmers and feed manufacturers.
In summary, as an important component of the fermentation feed breathing bag, multi-layer co extruded film achieves the preservation and nutritional value improvement of feed through its unique oxygen permeability. The control of its microporous structure and the selection of materials enable it to meet the respiratory conditions required by microorganisms during the fermentation process, while effectively blocking external pollutants and moisture. The application of multi-layer co extruded film in fermented feed breathing bags has stable oxygen permeability, good plasticity and tear resistance, and gradually reduces costs, making it highly favored by farmers and feed manufacturers.
