Mono Layer Laboratory Extruder
One extruder, one material stream. The simplest and most affordable LabEx line for testing and teaching.

ABA Laboratory Extruder for ABA Blown Film R&D
The LabEx ABA is a compact coextrusion line that produces three layer ABA blown film with only two extruders. One extruder feeds both outer skins through a flow splitter, while the second feeds the core. This is an economical way to test skin and core structures with recycled or lower cost material inside.

How ABA works
Three layers, two extruders
The ABA layout gives you a skin, core and skin film structure while keeping the machine compact and affordable.
Extruder 1 feeds the two outer A layers through a flow splitter into two concentric outer channels. Extruder 2 feeds the central B layer. A compact manifold keeps the flow balanced for stable three layer bubbles. Use the same material in both skins, with different colour or additive levels if required, and a different material in the core.
This is the practical, lower cost route to three layer film: place recycled or lower cost material in the protected core, while maintaining quality, colour, slip or antiblock in the skins.

Highlights
Why choose the ABA line
A focused coextrusion tool for skin and core development and cost driven recycled content trials.
Recycled or cheaper core
Place recycled, filled or lower cost material in the protected B core while the A skins provide the required surface quality.
Skins for colour and effects
Use the A layers for colour, slip, antiblock or a higher recycled content on the surface, testing skin recipes without touching the core.
Economical route to 3 layers
Three layer film from only two extruders, with a lower investment than a full three extruder coextrusion line.
Low material use, quick changeovers
Simulate real production with small quantities and fast recipe changes, ideal for R&D laboratories and pilot lines.
Table top or mobile modules
The extruders can be supplied as table top units or as stand alone modules on a mobile frame to suit your laboratory.
European build quality
Nitrided steel screws and barrels, a precision ABA die head and Schneider Electric Green Premium PLC, HMI and inverters.

Typical uses
What the ABA line is used for
Focused on skin and core development and cost driven recycled content work.
Skin and core R&D
Develop three layer structures with outer skins for colour, slip/antiblock or recycled content, and a modified core.
Recycled content trials
Increase recycled material in the protected core while keeping processability and surface quality in the skins.
Customer samples
Produce small batches of coextruded ABA film for customer samples and product trials.
Training and teaching
Show coextrusion principles clearly, with low material consumption, in schools and training centres.
