The 400ml RPC Superfos SuperLock, supplied to Ragú maker Symingtons by RPC Containers, has been selected in preference to glass due to its ambient shelf-life of up to 24 months combined with glass-like transparency and the added in-home safety.
SuperLock containers combine an oxygen barrier on all surfaces with a membrane seal to ensure an almost non-existent oxygen transmission rate, claims RPC. The barrier makes use of an in-mould labelling technique. Labels are manufactured using a co-extruded barrier foil and are applied during the injection moulding of the containers. After filling, the containers are sealed with a polypropylene (PP)/ethylene vinyl alcohol/PP membrane seal.
Virtually zero oxygen transmission is ensured, which provides an ambient shelf-life of up to 24 months. Packs can be hot filled and autoclaved during processing.
