S1 Digital Solventless Laminating Machine
Digital Solventless Laminating Machine with More Precise Tension Control
The S1 Digital Solventless Laminating Machine is a high-end model within the Suplock series by Sinstar, specifically engineered for large enterprises. As a professional flexible packaging laminator, it performs high-quality lamination on various plastic films, metallized films, aluminum foil, and paper.
The S1 operates efficiently with advanced flexible packaging lamination adhesives, ensuring a uniform and stable bonding effect.
Features of the S1 Digital Solventless Laminating Machine
Equipped with an advanced digital control system, it can not only manage up to 300 job orders but also precisely control parameters such as temperature, pressure, and speed, ensuring stable quality and uniform thickness of the composite materials. With a maximum speed of 500 m/min, it meets the demands of mass production and improves production efficiency.
Core components are sourced from internationally renowned brands, ensuring high reliability and a long service life.
While traditional laminators typically use solvent-based adhesives, digital solventless laminators utilize hot-melt or pressure-sensitive adhesives. This eliminates the need for organic solvents and reduces harmful gas emissions, thereby complying with modern environmental standards.
The three-roller back-pressure design ensures uniform and reliable film coating.
Tungsten Carbide Coated Roller, with wear resistance increased by 5 times.
One-click input for coating weight, easy to operate.
Dual-motor coordinated braking ensures uniform and stable coating.
Automatic glue proportioning ensures high operational efficiency.
Unique four-stage proportional protection mechanism.
Adopting a swing arm tension linkage system to ensure stable tension.
Adaptive Tension Control Technology, Intelligent Rewind Taper Control

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.
