Proof you can see in the dark
BPLP-60s is a luminescent additive, now in development, that makes compostable plastic self-authenticating. Shine a UV torch on it, switch the torch off, and genuine material keeps glowing. Counterfeits go dark at once.
Your cursor is a UV torch. Sweep it over both bags. The demo runs faster than the real material.Tap the bags to shine a UV torch on them. The demo runs faster than the real material.
Same print. Same price. Only some are real.
- Under UV light, every bag looks the same.
- Then the light moves on.
- Only material made with BPLP-60s keeps glowing.

Why genuine material keeps glowing
UV light lifts electrons to a higher energy level. In most materials, including the brighteners in many inks, they fall straight back down, so the glow stops the instant the light goes off.
In a phosphorescent material, part of that energy is held in a trapped state and released slowly. You see it as afterglow.
General physics of phosphorescence. BPLP-60s specifics are shared under NDA.
A printed word costs nothing to fake
Plain plastic printed with "compostable" sells for a fraction of the price of the real thing. Lab tests catch it, but they take weeks. BPLP-60s moves the check to the shop counter.
| How you check | Printed logo or mark | Laboratory test | BPLP-60s glow check |
|---|---|---|---|
| Time to a result | Instant | Weeks | Seconds |
| Where it works | Anywhere | In a lab | Anywhere, with a UV torch |
| Can a printer copy it? | Yes | No | No. It is inside the material |
| Changes to the film line | None | None | None. Added at compounding |
