Thermally stable PP jar

The September launch of Marks & Spencer’s new British Groceries range, with new branding for more 70 products, includes a coextrusion blown plastic jar solution.

The jar comes from RPC Containers Corby. RPC’s involvement is based on its close association with G’s Marketing, a renowned food grower that is Europe’s largest producer of beetroot. Based on the company’s experience in the fresh beetroot sector, where products are processed in a glass-free factory, G’s looked into available options in plastic containers and approached RPC Corby. The suggested solution was RPC’s standard 360- and 720-mL Thermic Ultra, a six-layer, coextrusion blow-molded, polypropylene/EVOH/PP plastic alternative to glass. This thermally stable container offers significant benefits in terms of lightweighting and easy opening.

Trials confirmed the compatibility of the jar with G’s new product range, so G’s approached Marks & Spencer about the possibility of launching the range. This coincided with the retailer’s own plans for the launch of its new British Groceries range, which comprises a repackaging of existing products as well as new additions, with a view towards improving the consumer experience.
