Starch is hydrolysed under controlled conditions to achieve desired viscosity, molecule size and  weight then hydroxyl group of starch are reacted  to have sufficient acetyl groups to prevent retrogeation and to have excellent film properties. The Smil-O-Ester are more stable and maintain constant viscosity over extended period as compared to normal Starch.

With this product effect of temperature is not as Critical or ensitive as with other starch modification. This starch allows moderate fluctuation in operating temperature without need to compensate for thicker or thinner flow.

Smil-O-Ester film has greater clarity, higher gloss, more flexibility, and strength, hydrating ability, oil and grease resistance. By combining all these efficient working characteristics with excellent film properties Smil-O-Ester has established new standards of specialty starch performance for the paper industry.
