Clear Aligner & Retainer Sheets. FLEX · DURA · CLEAR
PETG and multi-layer PETG + TPU thermoforming sheets for clear aligners and retainers — engineered for consistent forming and repeatable lab production.
PETG and PETG + TPU Sheets for Aligners and Retainers
Compare single-layer and multi-layer thermoforming materials for attachment templates, active aligners, and retainers.
FLEX Series.
Elastomeric multi-layer sheet that delivers a gentle, continuous initial force — with edges that trim and polish cleanly on the production line.
- Production-friendly edge finishing
- High resilience for continuous force
- Gentle initial force for sensitive-case protocols
DURA Series.
The production workhorse. Rigidity balanced with flexibility for sustained force delivery and low breakage across complex tooth movements.
- High fracture resistance
- High structural integrity & wear resistance
- Ideal for complex tooth movements
CLEAR Series.
Classic single-layer premium PETG with exceptional optical clarity — the cost-efficient choice for retainers and forming templates.
- High transparency for aesthetics
- Excellent stain resistance
- Consistent thermoforming behavior
Choose by material and workflow
For dental labs, aligner brands, and distributors, FLEX supports attachment templates and aligners; DURA supports aligners and retainers; and CLEAR is a single-layer PETG option for retainers and forming templates. All three series are available in 0.50, 0.75, and 1.00 mm, in 125 × 125 mm square and Ø 125 mm round formats.

Why multi-layer.
Bonded PETG and TPU layers put rigidity and elasticity exactly where the aligner needs them.
Structural integrity
The layered construction resists wear, cracking, and breakage — through thermoforming, trimming, and weeks of daily wear.
Optimized biomechanics
Rigidity where the treatment plan needs control, elasticity where the fit needs give — controlled force delivery from the start of wear.
Thinner, yet stronger
Multi-layer structure lets labs form thinner, more discreet aligners without giving up strength or retention.
Holds its force.
Lower force decay means more predictable tooth movement across the full wear period — the difference shows within the first 24 hours.
Force retained after 24 h — RayForm internal comparative testing under simulated intraoral conditions (37 °C). Approximate values; see the brochure below for the full series data.
Engineered for volume.
Production is supported by a line dedicated to aligner sheet materials, with options for different order volumes.
