Esco Bars Smooth 3 · Leak Prevention

Leak prevention is a quality issue that shows up in return rates long after the first order.

There is no shortcut on leak prevention: the Smooth 3 rewards preparation and punishes improvisation.

Retail staff rarely ask about leak prevention directly, but their questions almost always lead back to it.

Why leak prevention matters on the Smooth 3

Consistent filling torque and proper sealing rings remove most transit leaks.

The most common mistake is optimising for the first order instead of the fourth, which is where Smooth 3 economics actually settle.

Pressure changes during air freight are a common cause of minor seepage.

Frequently asked questions

How can leakage in Smooth 3 shipments be reduced?

Use sealed inner trays, keep cartons upright and allow a settling period before retail display.

Do you support long term supply agreements?

Can packaging be adjusted for our market?

Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.
