Machinery used for MAP did not require invention but is the result of the development of established packaging systems. In the late 1950s and early 1960s, experimental work in the commercial use of MAP was being undertaken. The horizontal form-fill-seal or pillow pack type of packaging machine was becoming established, setting a packaging style that is now commonplace. In Italy, a manufacturer of processed cheese attempted to introduce an inert gas into the packs produced on a pillow pack machine by flushing out the air prior to the pack being sealed. Given the unsophisticated type of sealing system then employed and the simple film structures available, it is unlikely that a successful result was achieved. However, this was the beginning, and as the demand for improved seals and efficiency of flushing increased, so manufacturers of machinery turned their attention to developing the pillow pack machine into a specialist MAP machine.
