PO film (polyolefin film), as a high-performance agricultural covering material, has been widely used in greenhouses worldwide in recent years, especially in high-latitude or frigid winter regions. One of its core advantages is its ability to maintain exc
By optimizing processing techniques such as blow molding and extrusion, the crystallinity and molecular chain arrangement of the film can be controlled, thereby improving its low-temperature performance.
During the blown film process, parameters such as mandrel rotation speed, blow-up ratio, and traction speed will change the orientation of molecular chains.
It's this combination of lightweight, high strength, and high barrier properties that has made PO film a disruptor of traditional packaging materials, leading technological innovation in the packaging industry.
In the modern packaging industry, shrink film is widely used for packaging food, beverages, daily necessities, electronics, and industrial products due to its excellent wrapping, protection, and display properties.
The fundamental reason why PE film combines both softness and exceptional tear resistance lies in its unique polymer chain structure, the intermolecular entanglement effect, and scientific processing technology.
