A Solventless Laminator bonds two layers using 100% solid-content adhesives. The adhesive is applied, and the materials are pressed together by big cylinders at room temperature or slightly elevated temperatures, where they chemically cure. Key advantages are environmental friendliness (zero VOC emissions), energy efficiency, high operating speeds, lower operational costs, and a more compact machine size. The main challenge is its higher sensitivity to material surface tension, workshop environmental conditions, and precise process control.

Peel strength depends on the perfect synergy between the materials, adhesive, and process parameters. Our laminators ensure optimal bonding through:

 Precise Coating System: Guarantees uniform adhesive application. For Dry Laminators, it precisely controls the adhesive coat weight (e.g., 2.5-4.0 GSM). For Solventless Laminators, it accurately controls the adhesive mixing ratio.

Uniform Drying/Laminating Pressure: Dry Laminators feature independently controlled temperature zones in the drying oven. Solventless Laminators have evenly stabilized nip roller pressure.
Professional Process Support: We provide initial parameter sets for various material combinations as a starting point for your production. Additionally, comprehensive operator training is included with the purchase of our equipment.

Our machine is compatible with common laminated flexible materials such as BOPP/CPP, PET/PE, PA/PE, and Alu Foil/PE etc. The prerequisite is that the materials must be pre-laminated, supplied on rolls with good flatness and uniform tension. For materials with extremely high or low coefficients of friction, or with excessively thick or thin sealing layers, it may be necessary to adjust the machine's process parameters, such as setting appropriate temperature and pressure, so can ensure the final pouch quality meets quality standards.
