NDC has developed an integrated silicone coating and glue coating for the precise application to a wide range of Linerless and pressure-sensitive labels as well as tape with online silicone coating. The integrated coating line includes with many different components, from unwind to rewind producing variety items for the client's product line up
Technology facts
1.Line speed: 300m/min
2.Material width: 1600mm
3.Real diameter: 1200mm
4.Unwinder: automatic turret unwinding
5.Rewinder: automatic turret rewinding
Silicone coating technology
1.Coating method：5-roller silicone coating (Optionally with 3 rollers )
The 5-roller system meticulously controls the application of silicone and the coat weight. The anilox roll applies the silicone from the buffer to the coating roll with exactly the right thickness. The coating roll then applies the silicone to the substrate. Each variable speed roll is independently driven delivering incredible precision. It also offers the ability to apply low silicone coat weights, making it a great unit to tap into the growing market for Linerless direct thermal labels
2.Silicone type：UV silicone coating; Silicone-free coating
3.Application：suitable for high speed single side silicone coated release liner (glassine, SCK, CCK, PCK, etc.) and film liner(BOPP, PE, PET) production
Coating technology
1.Coating method：slot die coating with rotary bar
It takes 90 days with 11 processing steps to finish a set of coating die to achieve high coating quality.
2,Application：Hot melt glue; UV glue; Water-based
Drying technology
1.Air flotation dryer with high efficient to ensure proper silicone cure at high speed
2.4 sections dryers, length 5m for each section
3.Humidity detection and control of recirculation air
4.Equipped with tension detection and vacuum rollers in the front and rear section of dryer module to control tension during the process.
5.High performance convection oven for all coating compounds
