What Bleher does

Bleher Folientechnik GmbH is a German specialty film converting company headquartered in Ditzingen-Heimerdingen, Baden-Württemberg, operating as a private, owner-managed GmbH (HRB 729081, Amtsgericht Stuttgart). Founded approximately four decades ago, the company employs 50 people, of which 28 work in production, and manufactures and converts biaxially oriented polyester (BO-PET) films marketed under the proprietary optimont® brand. The portfolio spans 7–500 micron thicknesses in transparent, opaque, mirror, white, black, and metallized variants, including UL 94 VTM-0 and VTM-2 flame-rated technical films (MF-AS, MF-SC, MF-MW, MF-WO, SC-VTM-0, TCA, CBF), food-safe window and barrier films, inkjet/laser/copy films, visor films for sandblasting helmets and face shields, electrical insulation films, BIO-based cellulose di-acetate (CDA) and PLA films, and recycled R-PET films. In-house capabilities include roll slitting (2–2,500 mm), sheet cutting (up to 1,800 × 2,000 mm), and surface treatments (Corona, Plasma, TCA).

The company sells exclusively to B2B customers — entrepreneurs, tradesmen, freelancers, and public institutions — with no sales to private consumers and a €1,000 minimum order value. Pricing is quote-based and not publicly disclosed; standard payment terms are net 30 days with a 2% Skonto discount for payment within 8 days. The GTM motion is sales-led: a Head of Sales (Eric Geringer), a Sales Manager (Daniel Blum), two sales representatives (Marc-Derek Ammer, Luis Temizkan), an inside sales and customer support function (Nadja Graf, Greta Tschan), and a dedicated France sales agent (Joël Pinault). Customer segments span industrial manufacturing (automotive, plastics, surface finishing), packaging (folding cartons, food-safe applications), printing (prepress, offset, screen, flexo, mounting, stencil), medical/safety equipment (visor films), artists/designers, and bio-based/sustainable packaging.

Bleher is certified to DIN EN ISO 9001:2015, holds OEKO-TEX STANDARD 100 for selected transfer films, maintains UL Recognized Components status (File E546905), and received an EcoVadis Silver Medal in 2026 with a 76/100 score (90th percentile of 150,000+ companies). The Ditzingen facility operates an in-house photovoltaic system covering approximately 21% of electricity demand and hosts 10 EV charging points. The company has no external investors, no parent entity, no subsidiaries, and no disclosed M&A activity, consistent with a classic German Mittelstand profile.
