Technical Specifications: Features high tensile strength (≥28MPa in longitudinal direction and ≥25MPa in transverse direction per ISO 527-3), with excellent puncture resistance (≥850g impact per ASTM D1709). Ideal for blow molding processes, it ensures bubble stability with thickness deviation ≤5% and a low heat seal initiation temperature of 110°C, making it suitable for high-speed packaging lines. The material exhibits haze ≤10% and gloss ≥85% (per ASTM D1003), delivering outstanding optical performance.
Application Fields: The extrusion and blow molding processes are utilized to manufacture frozen food bags, composite film inner layers, and vertical packaging bags for food packaging applications. In the construction and building materials sector, industrial films and packaging solutions such as FIBC (Foil-in-Bulk) bags are produced. Agricultural applications include specialized films and stretch films. Additionally, the lamination molding technique creates laminated boards for construction panels, while also serving specialized purposes like medical packaging films and high-transparency label substrates.
