What PP film is used for
Polypropylene (PP) blown film is a highly versatile material in the modern packaging industry. Its excellent clarity, stiffness, and moisture resistance make it ideal for specific end-use applications. Primarily, PP film is used for manufacturing garment bags, providing a protective and presentable covering for apparel. It is also widely utilized in textile packaging, keeping fabrics clean and secure during transit and long-term storage. Additionally, PP film serves as an excellent substrate for printed packaging film, offering a smooth, consistent surface for high-quality graphics and brand logos.
Why twin screws
Processing PP requires precise thermal management because it processes at different temperatures than PE. To handle these specific thermal requirements and ensure consistent melting, our PP film machines utilize a twin screw configuration, specifically featuring twin screws of 65 mm x2. This dual-screw design provides superior mixing and temperature control compared to standard alternatives. The extrusion line is driven by a robust 22 kW main motor, delivering the necessary torque for stable, continuous operation. Because PP and PE require distinct thermal profiles, exact recipe settings are confirmed with our engineers to optimize the process.
Width, output and materials
The machine is engineered to handle a variety of materials, including PP, PE, and CPE. In terms of production capacity, the line achieves a reliable output of up to 100 kg/h. The film width is highly adaptable, ranging from 200 mm to 1000 mm, and is fully customizable to meet specific production requirements. Thickness control is precise, allowing for a gauge of 0.01 to 0.15 mm per layer. This operational flexibility ensures that manufacturers can produce films tailored to exact specifications efficiently, reducing the need for multiple dedicated lines.
Integrating with bag making
When integrating the blown film process with downstream bag making, the consistency of the extruded film is critical. The precise thickness control of 0.01 to 0.15 mm per layer ensures that the film feeds smoothly into automated bag-making machinery without tearing or jamming. For applications like garment bags and textile packaging, uniform width and reliable output up to 100 kg/h prevent costly downtime on the production floor. If you require specific integration details or custom modifications for your bag-making setup, please confirm with our engineers.
