Advanced Functional TPU Film & Sheet Compounds | Multi-Constraint Film Solutions
Advanced Functional TPU Film & Sheet Compounds
For TPU film & sheet projects where one standard route is not enough.
Advanced functional compounds are designed for multi-constraint requirements such as
anti-block + unwind stability, low friction + abrasion, printable surface + adhesion stability, breathable waterproof balance,
lamination compatibility + aging resistance, and appearance consistency at scale.
This page is for you if your project keeps failing at the system level:
not “missing one property”, but balancing multiple functions without breaking film extrusion stability,
surface behavior, or downstream converting (printing / lamination / bonding).

Supply Format (Pellets-first, Film also available)
Choose the format that matches your setup
Film-grade TPU compounds (pellets) : primary
Best if you run your own film/sheet extrusion and want control over thickness, surface finish, and converting behavior.
- Functional stacking aligned with your printing/lamination/bonding process
- Better lot-to-lot control during scale-up and long runs
- Support on drying, haze control, anti-block/unwind, and surface stability
Finished TPU film (rolls) : optional
Best if you prefer ready-to-convert film for printing/lamination trials to shorten internal steps.
- Project-dependent availability (thickness, width, finish, winding)
- Recommended for fast validation with your real ink/adhesive/lamination line
- Still requires system verification (adhesion, scratch, blocking, aging)
When to Choose Advanced Functional (Fast Check)
Choose advanced functional when
- Your film has 2+ dominant constraints (e.g., anti-block + print adhesion; breathable + mechanical strength).
- Trials pass one test but fail another (print looks OK, then peels; unwind OK, then blocking appears).
- Your film line window is too narrow (haze drift, surface streaks, gauge instability, tack variation).
- Retesting cost is high and you need a short shortlist (2–4 routes) with higher success probability.
Typical “multi-constraint” combinations
- Anti-block + Unwind stability (high-speed converting, roll handling)
- Low friction + Abrasion (sliding contact, wear-critical surfaces)
- Printable surface + Scratch resistance (appearance films at scale)
- Lamination/bonding + Aging stability (heat/UV/humidity exposure)
- Waterproof + Breathable balance (WVTR vs hydrostatic vs softness)
Common Failure Modes (Cause → Fix)
Advanced functional work typically starts from a failure diagnosis: the issue is often an
imbalance between surface behavior, mechanics, and processing history.
| Symptom on Line / In Field | Most Common Cause | Typical Fix Direction |
|---|---|---|
| Blocking / hard unwind / roll-to-roll sticking | Surface tack too high; anti-block route insufficient; winding/cooling mismatch | Anti-block + slip balance; stabilize surface tack; optimize winding & cooling window |
| Print adhesion inconsistent (peels / scratches after aging) | Surface energy drift; migration; thermal history sensitivity; ink/primer mismatch | Surface-energy route tuning; lock drying & heat history; validate with your ink/primer system |
| Haze / gloss drift and appearance instability | Moisture sensitivity; contamination; unstable crystallization/phase behavior | Drying discipline; cleanliness; widen extrusion window; define appearance targets and method |
| Lamination delamination / weak bond line | Surface not compatible with adhesive; insufficient wetting; aging reduces bond strength | Bonding/adhesion route selection; surface compatibility tuning; verify peel after heat/UV/humidity |
| Breathable film: WVTR OK but hydrostatic fails (or vice versa) | Structure/compounding balance off; thickness/process drift; pore/phase control unstable | Rebalance structure + mechanical support; tighten gauge control; verify on real test methods |
Key principle: avoid “over-solving” one metric. A successful film compound is the one that delivers
stable converting + repeatable extrusion while meeting your real end-use tests (adhesion, blocking, aging).

Customization Options (Film & Sheet Relevant)
Below are typical directions we tune for film & sheet. Final feasibility depends on your process, thickness, and validation plan.
Surface & Converting
- Anti-block / unwind stability
- Low friction surface for sliding contact
- Matte/gloss control & appearance consistency
Printing / Bonding
- Printable surface-energy routes (ink/primer matching)
- Scratch resistance after printing
- Lamination & adhesive compatibility (project-dependent)
Durability / Aging
- Anti-yellowing & UV weathering routes
- Hydrolysis resistance (humidity / water exposure)
- Heat aging stability for long-life appearance
How We Run Trials (Shortlist → Stabilize → Verify)
1) Shortlist
We start from your converting method and dominant failure risk, then propose a small shortlist (usually 2–4 routes).
- Film structure (mono / co-ex / laminate)
- Thickness range & surface finish target
- Dominant constraint(s) and test priorities
2) Stabilize Extrusion
We tune the processing window so film runs consistently across long runs and real winding conditions.
- Drying discipline and haze control
- Heat/shear control and surface uniformity
- Cooling + winding stability (anti-block/unwind)
3) Verify on Real System
Confirm performance on your real converting line and end-use tests (not only resin-level data).
- Adhesion (peel / cross-hatch) and scratch tests
- Blocking/unwind evaluation at real storage conditions
- Heat/UV/humidity aging with appearance retention
Request Samples / TDS
We primarily recommend film-grade TPU compounds (pellets). If you need film rolls, share your width/thickness targets and required surface finish.
- Supply format: pellets (preferred) or film rolls (width, thickness, finish, winding)
- Structure & thickness: mono / co-ex / laminate; thickness range; target haze/gloss
- Dominant constraint(s): anti-block/unwind, low friction, printable surface, lamination/bonding, waterproof/breathable, aging
- Failure symptom (if any): blocking, tack drift, haze/gloss drift, print peel, delamination, yellowing
- Line conditions: film line type, output rate, drying practice, winding notes, and any surface treatment
