Saran is a Tamil film director from Coimbatore in Tamil Nadu. He was once an assistant to K. Balachander. He now owns a production houses called Gemini Productions and Saran movie factory.

Life and career

Saran's father T. Kulandaivelayudam worked with the directorate of examinations and many of his relatives are teachers. He finished diploma in visual communications from the College of Arts And Crafts and became an instructor in textile designing. But, even as a child, the only thing he wanted to do was direct films.

When he decided to take up the job as an instructor, his father couldn't make sense of it—he was earning about Rs 600, whereas others from his class went into advertising and made big money.

But Saran had a purpose. The institute he taught at was in Kodambakkam, where all the films happen, he wanted to be there, to breathe in that air, that atmosphere.

Saran worked as instructor for a year and, during this time, he did some work with a lady called Mohana who was art director for K. Balachander. KB was the director whom Saran admired above all others. Saran hoped this relationship would be the key to get to him.

Saran is the trade name for a number of polymers made from vinylidene chloride (especially polyvinylidene chloride or PVDC), along with other monomers. Since its accidental discovery in 1933, Saran has been used for a number of commercial and industrial products. When formed into a thin plastic film, the principal advantage of Saran, when compared to other plastics, is its very low permeability to water vapor, flavor and aroma molecules, and oxygen. This oxygen barrier retards food spoilage, while the film barrier to flavor and aroma molecules helps food retain its flavor and aroma.

History

Polyvinylidene chloride (PVdC) was discovered at Dow Chemical Company (Michigan, USA) in 1933 when a lab worker, Ralph Wiley, was having trouble washing beakers used in his process of developing a dry-cleaning product. It was initially developed into a spray that was used on US fighter planes and, later, automobile upholstery, to protect them from the elements. Dow Chemical later named the product Saran, and eliminated its green hue and offensive odor.
