Total and RPC Promens Consumer Corby have launched a multilayer polypropylene/ethylene-vinyl alcohol/polypropylene or PP/EVOH/PP jar using Injection Stretch Blow Moulding technology that offers even greater transparency and gloss for high barrier food applications.
The technology opens up opportunities in the retail sector, in particular markets such as cook-in sauces, instant coffee, ready meals, fruits and baby foods, producing packs that deliver high clarity for a premium on-shelf image along with the practical, convenience and safety benefits of plastic.
The light plastic jars will help retailers and brand owners meet sustainability targets in terms of packaging and carbon emission reductions.
The polymer development leads to improved aesthetics with ultra-low extractables, reducing overall migration, especially at high temperature conditions.
Together a new manufacturing process, RPC Promens Corby can produce multilayer containers that maintain their highly-effective oxygen barrier for long ambient shelf life, while delivering excellent clarity.
The containers are thermally stable to temperatures in excess of 100°C for pasteurization and sterilization.
A number of popular retail jar sizes are being developed with additional sizes planned for the future.
Caps, also supplied by RPC, are manufactured in PP for a mono material pack, which facilitates recycling.
