Solventless Lamination Machine
Solventless Lamination Machine
Modern food safety compliance and green manufacturing standards demand sustainable flexible packaging lines that completely eliminate hazardous chemical emissions. In solventless laminating engineering, transferring an ultra-thin adhesive layer onto high-velocity polymer films without using heavy thermal drying tunnels requires absolute mechanical precision. To fulfill this advanced ecological conversion standard, Micro Enterprise engineers next-generation multi-roll coating systems. We are an established Solventless Lamination Machine Manufacturer in Ahmedabad, Gujarat, delivering high-output machinery designed for high optical clarity.
Our industrial lamination lines are purposefully built to execute high-strength bonding across sensitive flexible films including PET, BOPP, and LDPE. Operating as a premier Solventless Lamination Machine Exporter from India, we construct robust machinery decks that achieve perfect chemical layout uniformity. This specialized technology completely eliminates the threat of layer separation or adhesive smearing, helping conversion plants reduce daily energy consumption while maximizing operational floor output.
The Mechanics of 5-Roll Transfer & Automated Heat Profiling
Controlling adhesive viscosity without solvent dilution requires strict mechanical and thermal regulation across the coating station. Functioning as a high-integrity Solventless Lamination Machine Supplier in Gujarat, our equipment utilizes continuous dosing networks to safeguard film integrity:
Precision 5-Roll Coating System: Employs a multi-roll transfer system to smoothly lay down an ultra-thin adhesive layer (0.8 to 2.5 GSM), preventing the “orange peel” texturing defect.
Integrated Oil & Water Heating Circuit: Features independent thermal management systems for the steel rollers to maintain a stable temperature profile, ensuring the chemical adhesive retains optimum wetting properties.
Target Substrates: Food-grade polyester (PET), biaxially oriented polypropylene (BOPP), low-density polyethylene (LDPE), and barrier Aluminum Foils.
Closed-Loop Servo Tension Control & Continuous Turret Splicing
The core operational efficiency of this eco-friendly machine depends on its advanced AC servo motion setup paired with sensitive load cells. Because solventless adhesives remain wet during the rewinding phase and require 24 to 48 hours of room storage to fully cure, web tension must be monitored precisely within a practical industrial tolerance of +/- 1 N to prevent internal film curling. To sustain high running speeds, our line integrates an automatic Dual-Station Turret Unwinder & Rewinder with Flying Splice, which executes roll transfers on-the-fly without causing linear registry distortions.
Key Technical Features Of Solventless Laminators
Continuous High-Speed Turret Splicer: Employs an automated rotary turret setup that executes instant roll indexing at full running speed, guaranteeing 100% continuous converting uptime.
Automated Mixing & Dosing Sync: Interfaces directly with high-precision 2-component adhesive mixers to ensure an exact resin-to-hardener ratio, eliminating un-cured spots.
High-Response Digital Load Cells: Monitors the film path continuously to adjust web torque, completely preventing core telescoping or wrinkles in the finished rolls.
Ergonomic Compact Footprint: Engineered with a compact layout that completely eliminates the need for massive overhead curing tunnels, drastically lowering plant electricity bills.

Solventless Lamination Machine FAQs:
Technical FAQs
Solventless machines use 100% solid adhesives that do not require a solvent (like ethyl acetate) for application. Consequently, there is no need for a drying tunnel, which significantly reduces electricity consumption (by 30%-40%) and eliminates fire risks associated with flammable solvents.
The machine features a Precision 5-Roll Coating System that ensures an ultra-thin and uniform adhesive layer between 0.8 to 2.5 gsm. This precision eliminates "orange peel" textures and prevents adhesive wastage.
Yes. It is equipped with high-response load cells and AC Servo Drives that maintain a constant web tension of +/- 0.1 N. This digital control prevents thin films from stretching, curling, or deforming during the lamination process.
This unit is built for high-speed industrial output, capable of reaching speeds between 400 to 450 m/min. The integrated automatic turret unwinder and rewinder ensure non-stop production with seamless roll changes.
Curing time depends on the specific adhesive brand and the ambient room temperature. Typically, the laminated material is ready for slitting or pouch-making within 24 to 48 hours.
machine integrates with advanced 2-Component Mixing & Dosing units. It features a monitoring system that triggers an alert or error if the ratio of resin to hardener is imbalanced, preventing lamination failure.
The most critical maintenance task is the thorough cleaning of the coating rollers after every shift. Maintaining the cleanliness of the 5-roll system and monitoring the thermal heating units ensures consistent bonding quality and a longer machine lifespan.
