Sodium silicate or Modified starch are hitherto used as adhesive for making Paper core. Both these adhesives are highly alkaline with very high pH which damage the paper and rollers of winders and also create hazardous working conditions for workman. It is also classified as highly pollutant and Disposal of the same is problem.
The biggest problem is that core prepared using these adhesives does not give high crushing strength or compressive strength to the core which is very much essential for the modern Paper machine. Paper reels gets damage while inserting chuck with high pressure to the end of the core resulting in rejection of Paper reel.
