Introduction
FlexBlow is the trade name used by UAB “Terekas”, a Lithuanian plastics machinery and packaging company based in Kretinga, Lithuania, that specializes in PET stretch blow molding equipment and related packaging solutions. The company began in the mid-1990s as a PET bottle and preform producer and later evolved into a machinery manufacturer focused on highly flexible, all-electric two-stage stretch blow molding systems for a wide range of bottle and container formats.
FlexBlow’s business is centered on the plastics packaging segment of the industry, where demand for shorter production runs, faster changeovers, format versatility, and energy-efficient equipment has increased alongside growth in customized consumer packaging. The company’s systems are used for PET container production and, in some configurations, PP preforms and specialty packaging applications, placing it within the broader ecosystem of blow molding machinery suppliers serving beverage, personal care, household, food, and specialty packaging markets.
History and Development
UAB “Terekas” was founded in 1994 in Kretinga, Lithuania, initially as a producer of PET bottles and preforms. By 1996, the company had begun developing its own stretch blow molding machinery, turning from a container producer into a machinery maker serving other plastics processors.
A major technical shift came by 2006, when the company’s machine line had been converted to fully electric servo-drive architecture, a step that aligned the product platform with industry trends toward lower maintenance, higher controllability, and improved energy efficiency. Over time, the FlexBlow brand became the company’s primary commercial identity, while the corporate entity remained UAB “Terekas.”
By the late 2010s, FlexBlow was emphasizing rapid format change, broad bottle-design flexibility, and automation-oriented features such as virtual simulation, predictive maintenance, and auto quality control. Company and trade-show materials also indicate that FlexBlow has expanded its export footprint and international service reach, reflecting the globalization of specialized blow molding equipment markets.
Business Operations and Segments
FlexBlow operates as a manufacturer of plastic packaging machinery and as a packaging-technology provider supporting container design, preform development, equipment integration, and after-sales service. Its commercial activity is centered in Lithuania, with manufacturing and corporate operations located at its Kretinga facility.
The company’s activities can be grouped into several practical segments:
- Stretch blow molding machinery
- Packaging and bottle design support
- Preform and container development
- Line integration and technical service
- After-sales support and process consulting
Business registry sources describe UAB “Terekas” as a Lithuanian private limited-liability company engaged in the manufacture of plastic packaging goods, with a registered office in Kretinga and majority Lithuanian ownership. Company data services and trade-show materials also indicate that FlexBlow exports a substantial share of production and maintains customers across Europe, North America, Asia, and other regions.
Products and Technologies
FlexBlow’s core products are two-stage reheat stretch blow molding machines designed for PET container production, with a product philosophy built around format flexibility and rapid changeover. The company’s standard and hybrid platforms are presented as covering a wide range of neck finishes, container shapes, and bottle sizes in a single machine family.
Typical technical features associated with the FlexBlow platform include:
- All-electric servo drives for motion control
- Intermittent linear preform feeding on standard models
- Hybrid rotary-linear configurations on higher-output systems
- Wide neck and container-size compatibility
- Fast format changeovers for short production runs
Publicly described model capabilities include machines suitable for very small containers as well as larger bottles and jars, with some systems marketed for wide-neck packaging and specialty shapes. Trade and industry materials also note applications in hot-fill packaging and in bottles requiring precise neck-to-body alignment, which is relevant for closures, dispensing systems, and premium cosmetic or specialty packaging.
Beyond molding equipment itself, the company presents its offering as a broader packaging engineering platform, including:
- Bottle and preform design
- Blow trimming
- Quality-control integration
- Packing-system integration
- Line setup and technical consultation
Applications and End Markets
FlexBlow equipment serves packaging producers and brand owners that need format agility rather than only maximum commodity throughput. This positions the company in market segments where product variety, smaller lot sizes, and frequent design changes are commercially important.
Reported end-use areas include:
- Beverage packaging
- Cosmetics and personal care
- Household chemicals
- Food packaging
- Specialty and custom container production
Industry-facing descriptions suggest particular suitability for producers of custom bottles, jars, and containers with unusual neck sizes or asymmetric forms. The flexibility of the machinery is also relevant to laboratories and prototype environments, where design validation and rapid iteration matter as much as steady-state output.
Global Presence and Market Position
FlexBlow is a comparatively specialized machinery supplier within the global plastics processing equipment sector, competing on flexibility, configuration range, and changeover speed rather than on scale alone. Its market position is closely tied to the growing need among packaging converters for machines that can economically handle both prototype work and smaller production batches.
Company communications indicate that a large share of production is exported and that the company has customers in markets including Germany, the United States, the United Kingdom, Japan, Latin America, Fiji, and the Philippines. Earlier and current trade-show participation records also show continued presence in international plastics exhibitions, including CHINAPLAS, where FlexBlow is listed as an exhibitor under UAB “TEREKAS.”
Research and Development
FlexBlow’s development model has historically combined in-house machinery design with close feedback from packaging users. A trade-association presentation from 2019 described the company’s technology direction in terms of digitalized and Industry 4.0-oriented features such as virtual simulation, instant costing, self-service interfaces, predictive maintenance, and automatic quality control.
The company also reports participation in an EU-funded project titled “Creation of Innovative Products,” running from July 2024 to January 2026. That project indicates continued investment in product development and engineering capability within the Lithuanian industrial innovation framework.
Sustainability and Environmental Initiatives
FlexBlow’s sustainability profile is primarily linked to all-electric machine architecture, which is generally associated in the blow molding industry with improved energy efficiency and reduced reliance on hydraulic systems. The company also emphasizes process efficiency through faster changeovers, smaller batch capability, and reduced warehouse space, all of which can lower operational waste in packaging production.
In broader industry terms, PET packaging remains under pressure to improve recyclability, resin efficiency, and production efficiency, and machinery suppliers are increasingly judged on how well their systems support those goals. FlexBlow’s publicly described technical emphasis on precision control, process flexibility, and integration with quality systems aligns with those industry expectations.
