Solvent-free laminating composite adopts solventless adhesive, which will not volatilize VOCs nor produce any irritating odor. It solves the problem of residual solvents in the packaging, eliminating the erosion of the organic solvent on the printing ink, can also achieve cleaning production, conducive to environmental protection.
2. Energy saving
The solventless laminating machine does not need to be dried, which reduces energy consumption. Moreover, in the late-ripening process, the maturation temperature of the solvent-free composite is substantially the same as the dry composite, so the energy consumption is also relatively close.
Since there is no organic solvent, so no need to adopt explosive and warm measures during production, transportation, storage and use and no need to specifically build a warehouse for solvent storage, more importantly, there is no harm to the health of the operator.
The speed of solventless machines adopting solvent-free adhesive is generally 250 ~ 350 m / min, even up to 400 to 500 m / min, while the solvent-based adhesive composite is generally 150 ~ 180 m / min.
