About Söhner Kunststofftechnik
Söhner Kunststofftechnik GmbH has specialized in plastic deep drawing (thermoforming) since 1968 and is one of the leading European manufacturers of reusable packaging for internal and external transport. The portfolio includes foldable large-load carriers (MegaPack), workpiece carriers, intermediate layers and container inserts, dividers made of PP hollow-profile sheets, reusable boxes, ESD packaging, blister packaging as well as special containers such as hazardous goods, heavy-duty and solar containers. Production takes place in single-sheet and twin-sheet thermoforming using materials such as ABS, ABS/TPU, HD-PE, PC, PS, PET, PVC and PP, partly electrically conductive for ESD protection. In addition to production in Schwaigern, the company offers development, in-house toolmaking, 3D printing, packaging tests, assembly of modules and recycling. Customers come from the automotive, electronics, automation, logistics, mechanical and plant engineering, retail and waste management sectors. Around 320 employees are based at the company's headquarters in Schwaigern.
