SJ-FMS-800 Dual-Extruder Extrusion Coating and Lamination Machine is designed and developed by ourselves, as the first one nationwide.

The machine adopts the construction of dual extruders and dual laminating rolls. It uses PP or PE as raw material, through the flow-casting coating and lamination technology, to accomplish double-sided lamination with substrates (such as plastic woven fabric, paper, etc.) in one production flow. The machine is especially suitable for using tubular woven sacks as the substrates, and producing double-sided coated tubular sacks or double-sided BOPP color-film laminated woven sacks.

The machine is characterized by simple structure and easy to operate. Compared with a single-extruder and single-die lamination machine, our machine can accomplish double-sided lamination with the substrate in one production flow, which improves production efficiency greatly, reduces energy consumption and labors, and guarantees products' quality.

For double-sided color printed film lamination, there are two modes for your choice as follows:

Manual Registration Mode: using magnetic powder brake tension control, manually adjusting for color-film registration. It is characterized by simple structure, easy to operate, and convenient for adjustment.

Automatic Registration Mode: using color-mark photocell detection, automatically registering the detected signals and adjusting (to control the motors of nip rolls for film feeding), so as to achieve automatic registration for color films at both sides. It is characterized by accurate registration, good stability, and high automation, which is especially suitable for producing high-grade double-sided color-film laminated sacks.
