BMT Blowscan and Thermoscan rPET bottle perfecting systems

BMT (Blow Moulding Technologies) has developed Blowscan and Thermoscan, which are designed to help manufacturers improve PET bottle performance, reduce waste and accelerate development cycles.

Blowscan is a lab-based, single-cavity stretch blow moulding platform, which is designed to deliver deep, data-driven insight into material performance, preform quality and bottle development, without disrupting production. Its modular design allows easy switching between free-blow and mould-blow modes. In free-blow mode, materials such as recycled PET (rPET) or bio-polymers are stretched without mould constraints, making it suitable for benchmarking material behaviour. Mould-blow mode is designed to support rapid prototyping and validation of new geometries, enabling fast iteration during early-stage design  

The system uses a batch-fed preform system with no conveyors or hoppers, and uses infrared to replicate industrial conditions. It captures key data, including preform temperature, inflation pressure and blow geometry, enabling comparison across materials and machine set-ups. From resin producers and preform manufacturers to brand owners, the system is designed to accelerate innovation, improve decision-making and build confidence in scaling sustainable packaging.

Thermoscan is a lab-based thermal imaging system designed to provide temperature data insights for sustainable production of preforms and bottles. It provides a data-driven way to manage material changeovers, narrowing process windows and reducing reliance on guesswork. By capturing the temperature profile of a successful vPET run, teams can set informed starting points for rPET and use the system to compare and fine-tune heated preforms to help ensure more consistent processing and performance.

The two systems will be exhibited at drinktec from 15–19 September 2025 in Munich, Hall C6, Stand 531.
