Unilever Uses IML Compression In The Mold

Procter & Gamble has been getting most of the press for low pressure thin-wall packaging developments, but Unilever is also in the game.

Unilever started working on new injection compression technology in 2011 with partners Plastisud (a moldmaker based in France) and Coveris (a processor based in Luxembourg). This week the three companies announced commercial development of the technology, which includes in mold labelling (IML).

tubThere is a reported 20 per cent weight (and resin) savings in the production of a 500g container for margarine. A 4X4 stack mold is used.

The system has been running for four months in the Coveris Center of Excellence for IM-IML in Ravensburg, Germany. The Ravensburg plant also processes materials from Coveris divisions in other countries, including the 40μm in-mold labels from Coveris’ EU Food & Consumer Business Unit in Angoulème, France.

The compression technology is integrated in the mold and runs independently on hydraulic or fully electric injection presses.

“Our injection compression IML is a great achievement in the improvement of the established injection molding IML technology,” says Yves Caunègre, group development manager at Coveris Global Rigid.

Coveris reports $2.6 billion in annual sales and has 66 production facilities globally.
