Tandem Extrusion Lamination
JDLM1300/110X2C, JDLM1700/110X2C
The extrusion coating & lamination line applies molten resin onto substrates to create high-strength, multi-layer composite materials for specialized packaging. We offer turrent tandem extrusion lamination machine features an operational speed of 240m/min, specifically engineered for coating and laminating with LDPE, PP, and other coating-grade resins. It is optimized for substrates including light-weight paper, aluminum foil, and non-woven fabrics. The line is widely utilized in medical packaging, food-grade films, office stationery packaging, and construction materials.
Components
- Double Station Center Unwinding Unit
Features dual-station unwinding with PLC-controlled tension to ensure the substrate maintains its original tension integrity. - Automatic Cutting & Re-connecting Unit
Facilitates seamless material roll changes and cutting without stopping the production line. - Automatic Web Guiding System
Utilizes ultrasonic sensors for displacement detection and a high-precision servo system for real-time misalignment correction. - Traction Unit
Provides stable and consistent web transport across the entire processing line. - Corona Treatment Unit
Equipped with three high-power corona treaters to increase surface energy and peel strength for subsequent processing. - Extrusion Unit
Incorporates US-developed screw and static mixing. The T-die extrusion ensures stable flow and neat film edges without splitting. - Triple Roller Lamination Compounding Unit
Features large-diameter rollers with dual-layer flow channels (temp variance < ±1°C). Silicone and back-pressure rollers ensure rapid cooling and bond quality. - Edge Trimming Unit
Removes excess material edges precisely to ensure consistent finished web width. - Automatic Friction Winder
Dual-station winding with PLC/servo-controlled cutting. Includes automated air-shaft loading and unloading for labor-reduced operation.
