In the manufacture of biaxially‑stretched films, the stretching machine orients molecular chains via machine‑direction and transverse‑direction stretching, endowing the film with outstanding mechanical and optical properties. As a core indicator for product quality, film‑thickness uniformity directl

In cast film production, thickness uniformity serves as the core quality indicator, which directly determines the optical properties and downstream processability of the film. A cast film machine forms films via melt casting and rapid cooling and shaping. Its thickness control performance relies on

In extrusion lamination production, the bond strength between the substrate and the film serves as the core indicator for measuring product quality, which directly determines the reliability and durability of composite materials during subsequent processing and end-use applications. The laminating c

Cast film manufacturers are often confronted with challenges including diverse raw materials and frequent order changeovers. Different materials such as PP, PE, EVA and TPU have remarkably different requirements in processing temperature, shear rate and cooling characteristics. Whether a cast film m

In extrusion coating production, the bond strength between the substrate and the coating film serves as the core indicator for evaluating product quality, which directly determines the reliability and durability of composite materials during subsequent processing and end-use applications. An extrusi
