RPC launches polypropylene packaging

Germany-based packaging firm RPC Bramlage has launched a new plastic pack using barrier multi-layer injection moulding technology to increase shelf life of food products.

RPC said the multilayer polypropylene (PP) pack is a low cost alternative to glass and cans for storing sensitive products like ready meals or paté.

The new pack can extend the shelf life of a food product to between 12 and 24 months depending on the food and the preservation technique used. The new packaging is compatible with sterilisation, pasteurisation and heat sealing.

The technology used to produce the pack is achieved by simultaneous injection of skin and core layers creating pack walls with an EVOH barrier layer surrounded by PP measuring 0.4mm in thickness.

RPC Bramlage food sales manager Matthias Hammersen said combining barrier and injection moulding technology in this way gives food manufacturers all the benefits of injection moulding in a pack designed for a long shelf life.

Hammersen further said the technology using in-mould labelling (IML) allows to make different shapes, as well as colourful and eye-catching designs of the new packaging.
