Hydrolysis Resistance
Hot-Melt Bonding
Printable Surface
Advanced Functional Custom
Choose Your Path (Go to the Right Subpage)
Start with the dominant constraint. For multi-constraint projects (e.g., optical + anti-yellowing, membrane + durability, bonding + low-temperature),
start from the closest path and request a combined shortlist via advanced functional tuning.
Protective Film (Surface & Optical)
Projects driven by clarity, haze control, scratch visibility, and long-term yellowing risk.
Anti-Yellowing
Anti-Block
Handling Wear
- Haze increases after handling or surface rubbing
- Yellowing under heat/UV/aging exposure
- Blocking and unwind instability on rolls
Waterproof / Breathable Membrane
Functional membranes where waterproof-breathable balance and hydrolysis/aging durability dominate.
Breathable
Hydrolysis
Durability
- Performance drop after heat-humidity or washing cycles
- Brittleness or elasticity loss over time
- Lamination mismatch on real structures
Hot-Melt Adhesive Film (Bonding)
Bonding projects where adhesion, activation temperature, and lamination window stability dominate.
Activation Temp
Lamination Window
Post-Aging
- Bond passes initially then delamination after aging
- Narrow activation window causing unstable runs
- Substrate compatibility constraints
Decorative / Printing Film
Aesthetic projects where print adhesion, surface energy, and matte/gloss + color stability dominate.
Ink Adhesion
Matte / Gloss
Color Stability
- Ink adhesion inconsistent across lots or conditions
- Color shift or gloss inconsistency after aging
- Appearance defects at scale-up
thickness, and the top 1–2 risks (yellowing, haze, blocking, delamination, print adhesion, hydrolysis).
We will route you to a shortlist quickly.
Typical Focus Map (Fast Reference)
This table is a router, not a datasheet. Final selection depends on structure, thickness, and validation plan.
| Path | Most Common “Why it fails” | What we tune | Recommended Page |
|---|---|---|---|
| Protection / Optical | Yellowing, haze increase, blocking, scratch visibility | Optical stability, anti-yellowing, surface anti-block, abrasion balance | Protective Film → |
| Barrier / Breathable | Durability drop after heat-humidity, brittleness, laminate mismatch | Hydrolysis route, aging package, breathability balance, laminate strategy | Breathable Film → |
| Hot-Melt / Lamination | Delamination after aging, narrow activation window, substrate mismatch | Adhesion system, activation temperature, lamination window stability | Hot-Melt Film → |
| Decorative / Printing | Ink adhesion drift, gloss inconsistency, color shift after aging | Surface energy, print adhesion, matte/gloss control, aging stability | Printing Film → |
| Advanced Functional | Multi-constraint conflict + unstable process window | Functional stacking + processing robustness | Advanced Functional → |
Note: Final performance depends on film structure, thickness, processing window, and verification method.
Customization Options (Project-Focused)
Film and sheet compounds can be tuned around real failure risks and scale-up conditions. Typical directions include:
Optical & Surface
- Anti-yellowing route selection (heat/UV/aging)
- Clarity / haze control and surface stability
- Anti-block and unwind stability tuning
Barrier & Durability
- Hydrolysis resistance for heat-humidity exposure
- Weathering and aging stability for outdoor use
- Low-temperature handling flexibility
Bonding & Printing
- Adhesion package tuning (substrate-specific)
- Activation temperature and lamination window robustness
- Surface energy and print adhesion (project-dependent)
Functional Stacking
- Combine multiple constraints (e.g., optical + anti-block + anti-yellowing)
- Balance membrane performance + durability + lamination stability
- Processing window tuning to reduce scale-up risk
Note: Customization scope depends on structure, thickness, target standards and verification plan.
For multi-constraint projects, start from the closest system page and request an advanced functional shortlist.
Request Samples / TDS
- If you extrude films in-house:
share film structure (mono / co-ex / laminate), thickness range, target properties and line conditions. We recommend suitable TPU compounds (pellets) with TDS/SDS. - If you source finished films:
share thickness, width, surface (matte / gloss / printable), roll specification and validation plan. We quote finished TPU films accordingly.
What should you do next?
If your project fits clearly into one category above, jump to the relevant subpage.
If you face multiple constraints or repeated trial failures, start from Advanced Functional.
