1. Because of the bidirectional nature of the molecular structure, it is best to apply the composite between the plastic film and the aluminized film, that is, the non-polar end will be firmly connected to the film, and the polar end will be firmly connected to the aluminized layer.Precautions For Flexible Packaging Composite Waterborne Adhesive

2. Because water is not volatile, it has strict requirements for drying process. The temperature should rise evenly from low. The drying air volume is sufficient, and the wind speed is controlled by 8-12m / s.Precautions For Flexible Packaging Composite Waterborne Adhesive

       The anemometer can be used for measurement here, but it must be noted that the impeller and sensing part of the anemometer must be made of metal, such as the aluminum impeller used by landmec’s CF-II anemometer. Precautions For Flexible Packaging Composite Waterborne Adhesive

      The general anemometer will deform and lose its function in the environment of more than 60 ℃ due to the use of ABS plastic as impeller.Precautions For Flexible Packaging Composite Waterborne Adhesive
