Polyex, a family-run business founded in 1991 and based in Lunéville (54), is a major player in the extrusion of polyethylene plastic films for industrial clients: shrink films and packaging, individual sheets, bags, covers, etc. Its expertise enables it to offer bespoke solutions for a wide range of sectors: construction, automotive, agri-food, retail, logistics, services, laundry, etc.
With 8 extrusion lines, 8 cutting/sealing lines and 7 in-line printing units, it can meet even the most complex requirements with the utmost responsiveness.
Already established in the industrial film market through its subsidiary Alfaplas (United Kingdom), SPHERE intends to expand within this European market, which offers strong growth potential.
“The Polyex acquisition enables us to consolidate our position as a European manufacturer in a thriving sector and to diversify our group’s markets, which are currently predominantly focused on the professional, local authorities and retail sectors. Polyex expertise is very complementary to the Alfaplas one and perfectly fits with our diversification strategy. Its geographical location is a major asset for our European expansion. My visit to the site and my discussions with the teams there have convinced me of this company’s professionalism.I am delighted with this transaction and would like to take this opportunity to welcome the Polyex teams to the SPHERE family”, said Jean-François Gallet, Chairman of the SPHERE Group.
“This new chapter in Polyex’s history is a source of great satisfaction for our whole team. Joining the SPHERE Group, a major and recognised industrial player in the household packaging sector, opens up new prospects for our company, whilst enabling us to preserve what has been our strength for over thirty years: our expertise, our responsiveness and our close relationship with our customers. We are convinced that this transaction will enable us to accelerate our growth, strengthen our offering and provide our customers with new solutions, whilst drawing on the expertise and resources of a leading European group. I would also like to thank all Polyex staff who, through their commitment and professionalism, have helped build the company we are today. We are embarking on this new venture with great enthusiasm and confidence,” said Xavier Seigne, Chairman of Polyex.
