Date：2026.06.10 Number：LET-NEW-237
Summer peak season is here – asphalt, lubricating oils, and hot chemicals are being shipped in large volumes. Filling temperatures often exceed 90°C. Ordinary packaging softens and ages rapidly under such heat, drastically increasing the risk of leaks. LET high-temp flexitank is specifically designed for hot liquids – with a special formula and proven performance in the world’s hottest regions.
01 Three Pain Points in High-Temperature Shipping
Packaging fails under heat
Standard plastic bags start to soften above 50°C and lose strength significantly above 60°C – high risk of rupture during filling or transit.Accelerated oxidation, product degradation
Asphalt and oils oxidize faster in high temperatures. Poor barrier properties lead to quality loss.High consequences of leakage
A hot-liquid spill means total cargo loss, potential injury to workers, environmental damage, and large liability claims.
02 Why Choose LET High-Temp Flexitank?

LET high-temp flexitank withstands filling temperatures up to 120°C+. The bag does not soften or age under extreme heat.
