Sauce manufacturer changes from glass to plastic

27 May 2014


British pasta sauce Ragú has changed packaging from glass to plastic.  Manufacturer Symingtons say that the change was due to longer ambient shelf life of up to 24 months combined with glass-like transparency and the added in-home safety of a non-shatter container.

The package also has an oxygen barrier on all surfaces with a membrane seal to ensure an almost non-existent oxygen transmission rate.

The barrier is created through the use of a leading-edge in-mould labelling (IML) technique. Labels are manufactured using a special co-extruded barrier foil and are applied during the injection moulding of the containers. After filling, health the containers are sealed with a PP/EVOH/PP membrane seal.

Together the two processes ensure virtually zero oxygen transmission to provide an ambient shelf life of up to 24 months. They are suitable for hot filling and autoclaving during processing. An additional filling line benefit is that the process is far quieter than other materials.

Ragú is Britain?s original pasta sauce and has been available since 1988. Its heritage dates back to the Cantisano Family in Rochester, New York in 1937 where Giovanni and Assunta Cantisano made Ragú sauce from the basement of their home, selling it door-to-door and through local shops.
