Our Story

Founded in 1949 as Winzen Film + Fiber, Inc. (“Winzen”), the company initially produced specialty films for research balloons used by the U.S. military and NASA.

In December 2012, PARI Olefins purchased the assets of Winzen from B.A.G. Corp. Located in Sulphur Springs, TX, the facility can produce blown films, liners, poly bags, PP high tenacity fiber, and fibrillated webbing. PARI Olefins sold its assets to trash bag manufacture and relocated to Taylor, Texas.In 2018, due to growth and strategically concentrate on each business segment, PolySachi Polymers a management company created along with Winlon Food liners as subsidy concentrating on food liners and made PARI olefins a subsidy to concentrate on FIBC solutions to manufacture high quality and safety components servicing FIBC markets in Mexico, India, Thailand and China from USA.

Winzen Fibers will be producing high tenacity PP yarn from 210 to 3000 denier from our plant starting May 2019.
