Case Story: How a Cream Jar Supplier Improved Lid Fit for a Korean Brand
Table of Contents
See how a cream jar supplier solved lid fit issues for a Korean skincare brand with custom cream jars, precise neck dimensions, and closure testing.
Context
A Korean skincare brand was searching for a reliable cream jar supplier for a new facial cream line. They chose Vesseluxe for its custom production, glass packaging experience, and ability to coordinate jars with matching closures. The brand ordered 50ml frosted cream jars with thick glass walls, a smooth cylindrical body, wide opening, matte white screw lids, and a minimalist printed logo.
Challenges
Loose Lid Fit
Some lids felt loose after repeated opening and closing, affecting the premium user experience.
Uneven Sealing
Small differences between jar necks and lids caused inconsistent sealing pressure.
Difficult Assembly
Operators needed extra force to close some cosmetic containers, slowing packing.
Cause Analysis
Our team measured the jar neck finish, lid thread, and sealing surface. We found that tolerance differences between the glass neck and plastic closure were causing unstable engagement.
Solution
As their cream jar supplier, Vesseluxe refined the neck dimensions, adjusted the lid thread, and matched the sealing liner to the jar opening. We also added torque and leak checks during production to verify closure performance.
Result
The improved cream jars delivered smoother lid engagement, more consistent sealing, and faster packing. Vesseluxe became the Korean brand’s trusted cream jar supplier for repeat packaging orders.
