Founded in France in 2020, Sealester started with intensive R&D before its industrial acceleration in 2023. We do not just manufacture pouches; we deliver outstanding consumer experiences and innovation.
Powered by our pioneering digital sealing technology, we liberate packaging from standard shapes. Through our "Design" and "Booster" offers, we co-develop innovative, eco-designed flexible packaging with our partners. We guarantee extreme agility—from 48h prototyping to production runs starting at 5,000 units. Using 100% recyclable materials like mono-polymers and apple composite paper, we ensure full compliance with AGEC and PPWR regulations.
Furthermore, we commercialize our digital sealing technology, empowering other industrials to invent new, sustainable packaging formats. As a true long-term partner, Sealester brings you localized production, reduced carbon footprint, and the future of circular packaging.
