Coating Food Solventless Laminating Machine

SEN-A1050/1350 Solventless Laminating Machine Overview

Engineered for exacting production environments, the SEN-A1050/1350 series redefines efficiency in flexible packaging. By utilizing advanced solvent-free lamination technology, this equipment completely eliminates volatile organic compound (VOC) emissions, ensuring full compliance with stringent international food-grade and pharmaceutical packaging safety regulations, including CE and ISO standards. The oven-free architecture significantly lowers energy consumption compared to traditional methods, directly improving your operational margins and delivering a rapid return on investment. Designed to handle plastic films, paper, and aluminum foil multi-layer substrates at exceptional speeds, it provides a reliable foundation for scaling your manufacturing capabilities while maintaining strict environmental compliance.

Core Engineering Advantages & Performance Metrics

1. Advanced Tension Control System: The material handling relies on a highly responsive dancing roller system integrated with Japanese Fujikura low-friction pneumatic cylinders. This configuration maintains exact web tension across varying roll diameters, preventing material stretching or snapping during rapid acceleration. The tactile feedback of the pneumatic system ensures smooth, continuous substrate feeding, which is critical when working with delicate or ultra-thin films.

2. Micro-Precision Coating Gap System: The critical gap between the scraper roller and the metering roller dictates the initial adhesive application. We utilize a premium Japanese-brand ball reducer to achieve an adjustment precision of ±0.001 mm (1 micron). This microscopic control absolutely eliminates common lamination defects such as trapped air bubbles, white spots, and uneven adhesive distribution. Furthermore, the system features a mechanical memory function. After routine maintenance or cleaning, the adjustment pointer automatically resets to your original gap setting. This tactile, click-into-place mechanism saves valuable setup time and removes human error from the calibration process.
3. Independent Servo-Driven Rollers: The coating section, metering roller, and transfer rubber roller are individually powered by dedicated servomotors paired with precise servo drivers. This independent drive architecture allows for exact synchronization of roller speeds. The result is a highly accurate, consistent adhesive coating amount across the entire web width, regardless of operating speed fluctuations.
4. Heavy-Duty Solid Steel Framework: To counteract the intense kinetic forces generated at 500m/min lamination speeds, the machine chassis is constructed from 80mm thick solid steel plates. Weighing between 14 to 15 tons, this massive physical footprint absorbs operational vibrations, resulting in a quiet, grounded hum rather than a rattling noise on your factory floor. To protect this immense structure during global transit, we utilize export-grade, high-strength, shock-absorbing fully enclosed wooden packaging, ensuring the equipment arrives at your facility in pristine condition.
5. Automated Shaftless Roll Handling: Both the unwinding and rewinding stations feature a shaftless automatic loading mechanism, complete with adapters for standard 3-inch and 6-inch paper cores. This automated lifting system drastically reduces the physical strain on operators when loading heavy raw material rolls, accelerating changeover times and maintaining a continuous production rhythm.

Optional Integration & Production Upgrades

1. Mono-Component Glue Machine Integration: Expand your adhesive compatibility by integrating a specialized mono-component glue dispensing unit. This modular addition is ideal for specific flexible packaging formulations requiring precise temperature and flow control, allowing your production line to adapt to diverse client specifications without requiring entirely new machinery.

2. Inline Corona Treater Device: Improve the surface energy of inert plastic films immediately before lamination. This electrical discharge treatment ensures maximum adhesive bonding strength, preventing delamination in the final packaged goods. The visible micro-sparking during operation guarantees that even the most resistant substrates are perfectly prepped for solventless adhesives.

3. Premium Electrical Control Systems: Depending on your facility's existing infrastructure and maintenance preferences, you can upgrade the core automation framework to either a Siemens Servo motor system or an Allen-Bradley (USA) electrical architecture. This ensures immediate compatibility with your plant's diagnostic tools, shortening the learning curve for your engineering team and streamlining future maintenance protocols.
