Polaroid Corporation pioneered and released instant photography products in 1948. Their film was initially made in house, but soon after many components was manufactured by Kodak. In 1969, Polaroid built their largest facility for manufacturing negative film in New Bedford, Massachusetts. Their Waltham based plant was also expanded. At the time, the newly built Norwood plant was for industrial and eyeglass polarizing material along with transparent instant films. By 1970 Polaroid started to manufacture a majority of their film products in house. Intergral film was manufactured in the Waltham (US) or in Enschede (Netherlands). Packfilm was manufactured in Waltham, Queretaro (Mexico), and Vale of Leven (Scotland). 4x5 sheet film was manufactured in Waltham. In the early 1980's they worked with Fuji Photo to produce Type 100 and Type 550 (4x5) compatible instant packfilm intended primarily for the Japanese market. Film production stopped in 2008. Shortly after, a group known as Impossible is leasing the Enschede plant and manufacturing compatible intergral films.
