The Double-layer LVT Flooring Extrusion Line is designed to produce two-layer luxury vinyl tiles in one continuous process.
Compared with traditional single-layer LVT lines, this system provides higher efficiency, better dimensional stability, and improved material utilization — making it an ideal choice for manufacturers seeking to reduce costs while maintaining high product quality.
The double-layer structure enhances floor strength, sound insulation, and temperature resistance, while ensuring a smooth surface for lamination or further processing such as cutting and click-lock profiling.

FAQ
Q1: What is a Double-layer LVT Flooring Extrusion Line?
A1: It is an advanced production line designed to produce two-layer LVT (Luxury Vinyl Tile) flooring sheets in a single co-extrusion process. The two layers are extruded simultaneously by separate extruders and bonded together through a double-layer T-die and calendering system.
Q2: What are the advantages of a double-layer design compared to a single-layer LVT line?
A2: Better dimensional stability and strength
Possibility to use recycled material in the bottom layer
Reduced material cost
Enhanced sound insulation and flexibility
Improved bonding strength between layers
Q3: What materials are used for each layer?
A3: Top Layer: Virgin PVC compound with decorative film and wear layer lamination.
Bottom Layer: Can include recycled PVC or lower-grade material for cost efficiency.
Q4: What is the typical layer ratio for double-layer extrusion?
A4: The ratio between the top and bottom layers is adjustable, commonly 70:30, 60:40, or customized based on product requirements.
Q5: What kind of extruders are used?
A5:The line is equipped with two twin-screw extruders — one main extruder for the top layer and one co-extruder for the bottom layer. Both feature high torque, precise temperature control, and stable output.
Q6: Can this line be integrated with online lamination or embossing?
A6: Yes. The system supports inline lamination of the color film, wear layer, and backing layer.
Optional embossing rollers can be added for wood grain or stone surface textures.
