PO film (polypropylene cast film), with its unique high-rigidity molecular structure and excellent mechanical properties, stands out among many flexible packaging materials, becoming a reliable choice for pressure protection.
During the stretch molding process, high melt index PE film, due to its excellent fluidity, can quickly fill the mold cavity, reducing processing time and energy consumption.
Plastic shrink film, as a key material in modern packaging systems, is widely used in the sales and logistics of industries such as food, beverages, daily chemicals, and electronics.
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.
