Porcher Industries Group is the world's leading technical textile and composite materials manufacturer. Based in Isère in Central France, the group has also established factories in China, the United States, and Brazil. Since the outbreak of Covid, the group has faced an unprecedented crisis as orders dropped dramatically and factories were threatened to be shut down. But this crisis has also allowed the group to test its adaptability by starting to manufacture tissue masks. What challenges did the French manufacturer face? How did it manage this difficult transformation? Could it pursue the same strategy in other countries as in France? Finally, will this experience allow Porcher Industries to enter the long-term medical textile sector, which is promising but highly regulated and complicated?
