What Constab does

Constab, formally CONSTAB Polyolefin Additives GmbH, is a German manufacturer of masterbatches and compounds for the polyolefin plastics-processing industry, headquartered in Rüthen, Germany and operating as a wholly-owned subsidiary of the publicly listed Israeli group Kafrit Industries (1993) Ltd. (Tel Aviv Stock Exchange: KAFR). Founded more than 50 years ago, the company is positioned as a market leader in masterbatches for BOPP (biaxially oriented polypropylene) films and serves plastics processors across packaging, automotive, construction, electronics, and filtration end-markets, with packaging described as the primary vertical.

The product portfolio centers on color and additive masterbatches plus custom compounds, with proprietary specialty lines including the patented Ecocell® chemical foaming agent (for lightweight, energy-efficient injection-molded and extruded parts, especially in automotive), CON-Xtend 21 barrier masterbatch (enabling recyclable packaging with reduced EVOH content), CONSTAB Charge Enhancers for PP meltblown nonwovens used in air filtration, food-contact-approved FL 08200 LL and FL 08204 LL filler masterbatches, odor-control additives, MDO PE film solutions for recyclable mono-material packaging, and the climate-neutral CONSTAB UV 01255 LD. A new in-house Pilot Plant (Technikum), commissioned in July 2024 with Collin lab extrusion and 3-layer blown / 5-layer cast film lines, supports both internal R&D and external toll compounding and product-testing services.

Constab operates an enterprise, direct-sales-led go-to-market via regional area sales managers covering most of Europe, the Middle East, South America and Asia-Pacific, complemented by trade-show presence (K, Fakuma, KUTENO, PLAST, PIAE, KPA, Plastindia, Plastics Brazil) and industry-association memberships (IK, EUPC, IVLV). Pricing is quote-based and formulation-specific, structured through multi-year contracts. Distribution is executed largely through KafritGroup sister companies (Kafrit Industries Israel, Suzhou Constab in China, Kafrit NA in Canada, Polyfil in the USA, Addvanze in Sweden, Delta Kunststoffe in Germany) and licensed for Pantone® color masterbatches. Revenue is derived almost exclusively from one-time product sales, and no standalone Constab revenue figure is disclosed.
