JWELL Front and Back Double-sided Composite Laminating Production Line
JWELL front and back double-sided composite laminating production line uses a plastic extruder to laminate coil surfaces or compound multiple substrates, improving tensile strength and moisture-proof performance for woven bags, valve-mouth cement bags and paper coating products.
Key Selling Points
- Front and Back Lamination: Designed for double-sided composite laminating of woven and paper webs.
- Optional Tubular Turn-Back: Optional 180° turning-back device for cylindrical fabrics enables one-pass double-sided lamination of tubular woven cloth as well as wide flat webs.
- Three-in-One Option: Optional second unwinding machine supports composite three-in-one products.
- Industrial Bag Coverage: Serves chemical, fertilizer, container and square-bottom valve cement bags plus food, aquatic and pet-feed bags.
- Paper Coating Uses: Also used for paper-cup paper lamination and packaging-paper lamination.
Technical Specifications
| Screw dia | Die width | Product width | Coating thickness | Max. mechanical speed | Total power |

Application Scenario
Widely used for chemical bags, fertilizer bags, container bags and square-bottom valve cement bags; rice and sugar bags; aquatic-product and pet-feed bags; and paper-cup or packaging-paper lamination.
Product Description
The equipment laminates coiled substrates or compounds multiple webs through plastic extrusion to raise tensile strength and moisture resistance for industrial and food packaging bags.
With the optional 180° tubular turn-back device, the same line can handle wide flat webs and one-pass double-sided coating of cylindrical woven fabric. Adding a second unwind enables three-in-one composite structures.
