As we all know, the choice of a variety of plastic film and other base film permutations and combinations, made it into laminate packaging materials, because although each material has unique properties, but a single base material can not fully meet the requirements of packaging performance, such as barrier property of oxygen resistance, gas resistance, water resistance; such as heat sealability, printing ability, heat molding property in post-printing demand. And after they are laminated after permutation and combination, the advantages of these materials are concentrated, which can not only meet the essential performance requirements, and also be presented in simplest form, even the laminate material of the same size costs only 1/3 of the original purchase price. As a result, a market for packaging with laminate materials emerged and laminating equipment for laminate materials was developed. Then why in the numerous laminating equipment and laminating process, more and more users will push to promote the solventless laminating machine, especially WSSL-A series solventless laminating machine?

Reason 1 .Compare to other laminating process equipment

(1) When WSSL-A series solventless laminating machine is used for laminating processing, the production cost is only 60% of that of other laminating equipment. Even lower. The comparison between Polaris solventless laminating machine and dry laminating machine was taken as an example

WSSL-A series solventless laminating machine does not need to eliminate the solvent in the adhesive by heating in the drying tunnel during the laminating process, only for the part of heating in the drying tunnel, The cost of drying channel and solvent emission channel can reduce 30% or even more. Therefore the procurement cost of whole machine will be lower than other laminating machine. Because there is no need to use the drying channel for laminating drying, therefore every solventless laminating production line can save at least 200,000 RMB/year in electricity.

The adhesive used by Polaris solventless laminating machine does not contain solvent, so the gluing cost is 50% lower than solvent-based laminating machine during the entire coating.

Specific performance:

①　The user of solventless laminating machine do not need to spend the cost of purchasing ethyl acetate
②　Contains no solvent, so there is no cost on solvent emissions

③　Because it does not contain solvent, the viscosity of bi-component solventless polyurethane laminating adhesive for solventlese laminating machine is higher than that of solvent-based adhesive. Therefore, in the same substrate and laminate conditions, the coating thickness of solventless adhesive is half thinner than that of solvent-based adhesive

Reason 2 . Compare with similar solventless laminating machine: WSSL-A series solventless machine has higher Intelligence. Specific performance

The automatic glue supply system of WSSL-A series solventless laminating machine solves the disadvantages of traditional manual glue mixing. With traditional manual glue mixing, adhesive undermixing will occur when sealing, which will limit the viscosity of adhesives to the maximum space, and the quality of laminate products will be difficult to achieve the best. Use the automatic glue supply system of Polaris solventless laminating machine can finished the glue supply, glue mixing and glue putting with stable performance. The theoretical and practical error of mixing ratio control of automatic glue mixer of WSSL-A series solventless laminateing machine is less than or equal to±2%~3%. This is a negligible error value. This automatic glue supply system not only guarantees the quality of laminated products, but also reduces the dependence of users on advanced operators and reduces the production risk caused by human factors.

The coating accuracy before solventless laminating is also an advantage of solventless laminating machine compare with other laminating machine.

The coating accuracy not only determines the quality of the laminate product, but also has a decisive role in the cost of purchasing adhesive. The coating accuracy can be solved by adjusting the gap between the rubber roller and the metering roller, controlling the speed ratio between the metering roller and the transfer roller, and controlling the speed ratio between the transfer roller and the coating steel roller. These processes in traditional operations require manual use of feeler gauge to measure the gap, and then use hand wheel to adjustment calibration to complete the work. These very test the operator's professional. In order to reduce users' dependence on advanced operators, reduce the production risk brought by human factors. Polaris solventless laminating machine for the operation of this process directly using self-developed technology system [CCMS],[CWDS]& [PCWD], users only need to input the coating range value and coating thickness value in the man-machine interface, to complete the work.

(2) The laminate file produced by WSSL-A series solventless laminating machine have the characteristic of low price, better performance, more healthier, more safer. The specific performance details as below:

Because the production cost of WSSL-A series solventless laminating machine is lower than that of solvent based laminating machine, Therefore, the finished film has a strong price competitive advantage

All kinds of laminate material produced by WSSL-A series solventless laminating machine have better hygienic properties. Because the glue used byWSSL-A series solventless laminating machine is solventless, the glue is no odor, odorless and non-toxic. Therefore, various laminate materials produced by WSSL-A series solventless laminating machine are used to package food, and there will be no problem of food contamination due to residual solvent in the food high-temperature sterilization when seeping into the package.

In general, Polaris solventless laminating machine subverts the production mode of high energy consumption and high pollution of traditional laminating process equipment, and has been favored by users through resource saving, green environmental protection and friendly operation. This is why more and more users choose Polaris solventless laminating machine.
