Polaroid is closing factories in Massachusetts, Mexico and the Netherlands and cutting 450 jobs as the brand synonymous with instant images focuses on ventures, such as a portable printer for images from cell phones and Polaroid-branded digital cameras, televisions and DVD players. This year’s closures will leave Polaroid with 150 employees at its Concord headquarters and a site in the nearby Boston suburb of Waltham, down from peak global employment of nearly 21,000 in 1978.
