The WRJ i9 Solventless Laminating Machine handles various materials, such as plastic films, metallized films, aluminum foil, and paper, offering excellent versatility and reliability for diverse lamination needs. With over 1,500 units successfully installed globally, it has earned widespread market recognition.
Introduction
The WRJ i9 is a 2-layer solventless laminating machine specifically designed for the flexible packaging industry. Utilizing eco-friendly and high-efficiency solventless adhesive technology, it laminates two different materials—such as plastic films, metallized films, aluminum foil, and paper—into high-performance laminated films. Characterized by high productivity, excellent stability, and environmental benefits, this machine serves as essential equipment in modern packaging material production lines.
Main Advantages
Easy Operation: Minimizes operator intervention during production through a simplified control system.
User-friendly: The intuitive design and clear operation logic enable beginners to master the operation within just two days.
Stable Operation and Tension Control: Through multi-stage tension control and a stable combining pressure system, it ensures a flat and uniform lamination effect for different materials even at high speeds.
Efficient Two-Layer Composite Structure: Specifically designed for dual-layer material lamination, featuring a compact structure and high efficiency, making it suitable for the daily production of mainstream flexible packaging structures.
Excellent Material Adaptability: Compatible with a wide range of common substrates—including BOPP, PET, PE, CPP, VMPET, nylon films, aluminum foil, and paper materials—meeting diverse packaging requirements.

Frequently asked questions
1. What is the difference between the Fi9, i9 and S1 Digital models?
Fi9 is the standard high-output solventless laminator, i9 is configured for two-layer lamination, and S1 Digital is the digital-control variant for shorter runs and tighter recipe management. The right model depends on your mix of structures and run lengths, not on the highest speed in the catalogue.
2. Why laminate without solvent instead of with solvent?
Three reasons: no drying tunnel, so no solvent evaporation energy and no effluent treatment; no solvent residue in the laminate; and a more compact line. The trade-off is a more disciplined process — mixing ratio, pot life and web tension are less forgiving than with solvent-based adhesive.
3. Which adhesive systems does the machine handle?
100 % solids two-component polyurethane systems, in the standard configurations. Adhesive chemistry must be matched to the film structure; the machine cannot compensate for an adhesive that is wrong for the application.
4. What coating weight range is achievable?
Coating weight is set by the application and the adhesive system, and is quoted together with the machine configuration. What matters commercially is grams per square metre of laminate, not the number on the datasheet — the comparison with solvent-based adhesive must be made on that basis.
5. Do I need a curing room?
Yes. Solventless adhesive cures in a controlled environment with defined temperature and time. Without a curing area, the process does not close — the laminate may look acceptable and fail in slitting or in the customer's packing line.
6. How is tension controlled?
Closed-loop tension control on unwind and rewind, with taper control and edge guiding. Tension and guiding are where most lamination quality is decided, particularly on thin films and aluminium foil.
7. What is the minimum run length that makes sense?
It depends on start-up scrap and setup time against the volume per recipe — not on the total plant volume. Short runs with frequent structure changes make the machine work harder for the same output.
8. Who manufactures the machine and who supports it?
The solventless laminators are manufactured by SINSTAR in Chongqing. XIAOPAI supplies them worldwide as authorised distributor and is responsible for specification, documentation, installation coordination, training and after-sales.
