French firm Total and RPC Promens Consumer Corby have developed a new multilayer PP/EVOH/PP jar that offers better transparency for storing high-barrier food applications.
The firms have manufactured the new plastic jars with injection stretch blow moulding (ISBM) technology, which provides superior gloss and clarity.
RPC Promens Corby has sourced metallocene-based polypropylene (PP) from Total, which is used for the ISBM technology. Specially developed for ISBM, the PP can reduce migration of chemical contaminants from contact materials into food.
The jars can withstand temperatures more than 100°C, which makes them ideal for pasteurisation and sterilisation.
The multilayer jars can ensure long, ambient product shelf life by acting as a efficient barrier against oxygen.
The container caps have also been manufactured from PP, which facilitates recycling.
The lightweight plastic jars can be used for storing cook-in sauces, instant coffee, ready meals, fruit and baby foods.
Use of the variant can also help retailers and brand owners in reaching sustainability targets when it comes to packaging and carbon emission reductions.
RPC Promens Consumer Corby is offering the jars in multiple popular retail sizes and have additional sizes planned for the future.
The firm manufactures extrusion blow-moulded barrier bottles and wide-necked jars, and works as a unit under the RPC Group.
Another RPC unit, RPC Promens Consumer Kutenholz had launched 1,000ml round bottles for salad dressing firm Sylter Salatfrische in August.
