Is Your Flexitank Really Safe? Let Data Speak
Date:2026.05.23 Number:LET-NEW-233
How LET keeps incident rate below 1‰ – from raw material to global delivery
Every day, we hear the same question from customers around the world:
“Will it leak? Is it really safe?”
It’s a fair question. Liquid bulk shipping carries risk. And not all flexitanks are created equal.
At LET, we don’t answer with slogans. We answer with data, process, and full-chain control.
Here’s what keeps our incident rate below 1‰ – far lower than the industry average.
1. Raw Material: Virgin Only. No Compromise.
We use 100% virgin resin from Dow and ExxonMobil (8-carbon metallocene).
No regrind. No recycled material. No unknown additives.
Every batch is tested for melt flow index, density, and tensile strength before entering production.
👉 Good materials are the foundation of safety.

2. Full In-House Production: From Film to Valve
Unlike many assemblers, LET controls the entire chain:
Blown film – German technology, fully automated, thickness deviation ≤±2%
Valve injection molding – In-house, not outsourced
Welding – Millisecond precision, 30% stronger than national standard
Cleanroom – Class 100,000, with air shower and ozone sterilization
👉 When you make everything yourself, you control every detail.

3. Testing: Destructive & 100% Valve Check
Safety is not about sampling. It’s about 100% verification.
First-piece inspection – Every batch starts with a destructive test (puncture, tensile, seal strength)
Valve air-tight test – Every single valve, not just spot checks
Traceability – Each flexitank has a unique ID linking to raw material batch, operator, and test records
👉 If it doesn’t pass, it doesn’t ship.

4. Insurance: $1 Million Product Liability Coverage
Even with the best quality control, we believe in being prepared.
$1,000,000 per incident
Underwritten by a globally recognized insurer
Covers major trade routes
👉 Your cargo has real financial backup.

5. After-Sales: 24/7 Response, On-Site Within 6 Hours

24/7 emergency hotline
