See? RBC Containers Corby makes blowmolder investment

New injection stretch blowmolder provides better transparency in containers.

December 9, 2014   by Canadian Packaging staff

RPC Containers Corby has invested in new ISBM (Injection Stretch Blow Molding) technology that enables it to offer its established high barrier PP/EVOH/PP (Polypropylene/Ethylene vinyl alcohol/Polypropylene) containers with even greater transparency.

The company says this 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.

Equally important, the substantially lighter weight of the plastic jars will help retailers and brand owners meet sustainability targets in terms of packaging and carbon emission reductions.

The development of a special new manufacturing process has allowed RPC Corby to produce containers that incorporate its effective EVOH oxygen barrier for long ambient shelf life, while delivering excellent clarity.


The containers are thermally stable to temperatures in excess of 100°C for effective pasteurization and sterilization.

A number of popular retail jar sizes are being developed with additional sizes planned for the future.  Caps are supplied by RPC Halstead.
